Buying a diamond is confusing. On the surface, it seems like nothing makes sense. Take a look at this diamond from Amazon and then take a look this diamond from Blue Nile. They’re both one carat diamonds. Does it make sense that they’re the same size, yet one costs $1,179 and the other $16,500? To make it even crazier, the Blue Nile diamond may actually be a better value!

Basic Rules: The Three Steps to Buying a Diamond

Below we will be getting into the nitty gritty details that determine the price of a specific diamond. Its important to understand this so that you can determine what is important for you when making this purchase. Take a look at this beautiful 1.00ct G VS1 diamond and compare it to this 1.02ct E VVS2 diamond. Can you see any difference between the two? I can’t. But I can see a $1,600 difference in price (20%).

Lately we have been seeing interest on this topic from readers considering Lab Created Diamonds. While we are outright fans of LCDs, we do have an article discuss this topic and how it pertains specifically to lab created diamonds. In this article, we discuss the issues we have with LCDs as well as advice on how to get the best LCD diamond if you decide to go that route. The basic question is are you willing to sacrifice long-term value for short term bang for your buck? If you do decide to go for a lab created diamond, we recommend James Allen.

When discussing pricing and what is a fair deal, you have to know what you want and how to be sure you are getting what you are paying for. You need to make sure you are following the process to ensure you aren’t getting scammed. It’s hard figuring out how much you should spend on a diamond. It’s just as hard figuring out how to get the best bang for your buck.

1) Certification – This is the most important step. It is an absolute must if you are spending more than $1,000 on a diamond. The purpose of buying a diamond with a certificate is to have peace of mind that you are getting what they claim. The only certificates that provide that are from the GIA and AGS laboratories. They are the gold standards for the diamond industry.

2) Quality – Now that we know which certificates to use, we need to understand all the qualities listed on the certificate and what we should do with that information. You may have heard of the four Cs of diamonds and we have articles on each of them: Color, Clarity, Cut and Carat.

I will use color as an example. If you decide to go with an elegant solitaire setting like this one or this one, you can focus on J+ to maximize value. But if you are going for a more elaborate halo setting like this one, you will need to stick with H+.

I understand that this gets a bit confusing trying to balance the different diamond proportion and qualities. If you prefer more personal help guiding you through the qualities, feel free to contact us.

3) Pricing – We get into the deep background below, but the easiest way to figure out the price is the same way you do with anything else. Shop around. Blue Nile and James Allen are the industry leaders when it comes to diamonds (like Amazon is for many products). A store will always be more expensive than what you can find online, but figure out the right baseline and then you can decide if its worth paying premium “X” for the added value you feel you are getting from the store.

For example, we reviewed Shane Co and were offered a 1.01ct I VS2 cushion cut for $6,477. Firstly, had you gone through our education on quality, you would know that this was an undesirable diamond (cut a little too deep and better to avoid “I” color in cushion cuts. Next, we can do a quick price compare. Here is a superior diamond from James Allen (better cut, higher clarity) for $2,800 and a similar diamond from Blue Nile that is an even better deal coming in at $2,779.

You don’t need me to tell you that the Shane Co diamond is horrifically priced.

Bottom Line Recommendation

Follow these three steps to ensure you are getting proper value. There are some other pitfalls you need to avoid as well (e.g. enhanced diamonds or fluorescence).

Diamond Prices

Diamond prices can vary hugely depending on a diamond’s shape, cut quality, clarity and color. For example, the cost of a one carat diamond can range from just $1,500 to more than $16,000 for an extremely well cut, high quality diamond, while a two carat diamond could cost as little as $6,000 or as much as $80,000 based on its shape, cut, clarity and color grades.

As you can see, this is a huge range, with some diamonds costing as much as 10 times higher than other diamonds of the same carat weight.

Diamond prices depend on such a wide range of factors that’s very difficult to give an accurate price estimate for “diamonds” as a whole. The biggest of these are the four Cs, which we briefly mentioned earlier — cut quality, clarity, color and carat weight.

The better a diamond’s four Cs (or, in the case of carat weight, the higher) the more expensive it will be. In short, the better a diamond’s quality, the more you’ll need to pay to purchase it.

Now, this doesn’t mean that you can’t get a good quality diamond without paying a fortune. With diamonds, the key is to maximize the amount you spend on the factors that affect the diamond’s appearance, all while minimizing the amount you spend on the factors that don’t.

We’ve covered this in more detail further down the page. For now, let’s start by looking at how a diamond’s price is calculated based on its carat weight, color, clarity and other factors.

Calculating Diamond Price Per Carat

Diamonds are all priced per carat. Lets say a 0.50 carat diamond has a price of $1400 per carat. That diamond’s price for the stone would be $1400 * 0.50, or $700. Or, let’s say that a 1 carat diamond has a price of $4,100 per carat. This one is easy to calculate — since the diamond is 1 carat, the price for the stone is exactly the same — $4,100.

Diamond prices per carat increase as you jump up to higher weight categories. In short, the higher the diamond’s carat weight, the higher the total amount you’ll need to pay per carat to purchase the diamond.

Diamond Prices from 0.08ct to 1.00ct by size “categories”

Therefore, diamond prices increase exponentially with weight, since their prices increase both due to the increased weight and due to the higher price per carat for the increased weight category.

Below, we’ve provided a table with the average price range per carat for diamonds of different carat weights. Since diamond prices can vary based on shape, we’ve used the round brilliant cut (the most popular and expensive diamond shape) for our data.

You can find more information on the relationship between a diamond’s shape and its price in our guide to diamond shapes and pricing.

To provide useful data, we’ve also restricted our search to diamonds with a color grade of K or higher and a clarity grade of SI2 or better.

Diamond Carat Weight Price (Per Carat, Round Brilliant Cut)
0.50 carat $1,220 – $5,800
1.0 carat $2,500 – $18,000
1.50 carat $3,400 – $24,000
2.0 carat $4,200 – $29,000
3.0 carat $7,200 – $51,000
4.0 carat $8,400 – $71,500
5. 0 carat $9,600 – $67,500

It’s actually possible for the price range per carat to actually be wider than this. For example, a diamond with very low color and clarity grades (for example, M and I1) might cost slightly less per carat than the price ranges listed above.

However, is this a desirable diamond? Outside of certain circumstances, most likely not. At the other end of the scale, the highest end of the price ranges listed above is reserved for diamonds with exceptionally high color and clarity grades, which often don’t offer ideal value for money.

Price of 1 Carat Diamonds

The price of a 1 carat diamond is between $1,300 and $16,500, depending on factors such as the diamond’s cut quality, clarity, color and shape.

Below, we’ve listed the average price ranges for 1 carat diamonds in all 10 of the most common shapes. Like above, we’ve restricted our search to diamonds with a clarity grade of SI2 or better and a color grade of K or higher. There are also amounts in parentheses for diamonds of the same category but with recommendable paramethers to provide pricing data that’s relevant for you as a buyer:

  • $2,500 ($3,000) to $16,500 for a round brilliant cut diamond (view prices)
  • $1,600 ($2,000) to $11,000 for a princess cut diamond (view prices)
  • $1,600 ($2,000) to $9,500 for a cushion cut diamond (view prices)
  • $1,600 ($1,750) to $10,500 for an emerald cut diamond (view prices)
  • $1,600 ($2,000) to $10,000 for an oval shape diamond (view prices)
  • $1,300 ($1,800) to $7,000 for a radiant cut diamond (view prices)
  • $1,800 ($2,100) to $6,900 for an asscher cut diamond (view prices)
  • $1,700 ($2,300) to $10,000 for a marquise cut diamond (view prices)
  • $1,700 ($1,900) to $12,000 for a heart shape diamond (view prices)
  • $1,700 ($1,900) to $11,400 for a pear shape diamond (view prices)

Below the 1 carat mark, diamond prices per carat are significantly lower. Here’s what you should expect to pay for a diamond that’s smaller than 1 carat:

  • What is the price of a 0.5 carat diamond? A high quality 0.50 carat diamond (H color and VS2 or higher clarity) costs about $2,500 per carat, meaning that the price of the diamond itself is approximately $1,250.
  • What is the price of a 0.25 carat diamond? A 0.25 carat (quarter of a carat) diamond with the same color and clarity grades as above costs around $1,600 per carat, making the price of the diamond approximately $425.

Price of 2 Carat Diamonds

The price of a 2 carat diamond ranges from $6,500 to $55,000, depending on the diamond’s cut quality, clarity, color and shape.

Below, we’ve listed the average price range for 2 carat diamonds in the most common cuts and shapes. Like above, our price ranges use a minimum color grade of K and a minimum clarity of SI2, which limits out most diamonds that aren’t aesthetically pleasing enough to consider. And also there are prices in parentheses which indicate the minimum for diamonds with recommended specs:

  • $7,400 ($9,000) to $55,000 for a round brilliant cut diamond (view prices)
  • $6,200 ($7,000) to $31,500 for a princess cut diamond (view prices)
  • $5,600 ($7,500) to $28,300 for a cushion cut diamond (view prices)
  • $5,700 ($8,500) to $33,270 for an emerald cut diamond (view prices)
  • $7,200 ($8,300) to $33,000 for an oval shape diamond (view prices)
  • $6,500 ($7,000) to $29,500 for a radiant cut diamond (view prices)
  • $7,700 ($8,000) to $35,700 for an asscher cut diamond (view prices)
  • $9,400 ($10,500) to $36,900 for a marquise cut diamond (view prices)
  • $7,600 ($8,000) to $33,800 for a heart shape diamond (view prices)
  • $7,400 ($8,000) to $42,400 for a pear shape diamond (view prices)

Current Diamond Prices

As with other precious items, the market price for diamonds tends to increase with inflation. This means that diamond prices published several years ago aren’t fully accurate now and may be less than helpful if you’re shopping for a diamond.

Below, we’ve published the current diamond prices for a round brilliant cut diamond in a variety of carat weights. Note that the prices published below are for the whole diamond, not per carat:

  • 0.50 Carat: $600 to $2,900
  • 1 Carat: $2,500 to $18,000
  • 1.50 Carat: $4,800 to $35,000
  • 2 Carat: $8,500 to $59,000
  • 3 Carat: $20,000 to 155,000
  • 4 Carat: $35,500 to $286,000
  • 5 Carat: $45,500 to $337,500

How to Save Money When Buying a Diamond

As you’ve probably noticed, the price ranges we’ve listed above for different diamond shapes and carat weights are very large. For example, a 2 carat round brilliant cut diamond can cost upwards of $50,000, or as little as $7,400.

Saving money when buying a diamond is all about finding the intersection where a diamond’s quality and its value for money intersect.

There are several steps involved in doing this. The first is recognizing that diamonds are often priced based on their “category” rather than an objective measure of their appearance or actual quality.

The second is to understand how the diamond cutting process affects the price at which a loose diamond can be sold.

The third is to learn how a diamond’s color and clarity grades affect its price, as well as how the right choice of color and clarity grade can help you buy a beautiful diamond at the right price.

We’ve covered all three of these steps below, along with examples of how each factor affects a diamond’s price, as well as how you can use it to your advantage as a buyer.

The Importance of Categories

I stress categories, because you might mistakenly believe that prices per carat increase continuously as weight is increased, but this is not the case.

Since diamonds are a retail product driven more by emotion than reason, a 0. 99ct diamond is worth only about 1% more than a similar diamond weighing 0.98ct. But a 1.00ct diamond is worth about 20% more than a similar 0.99ct diamond. Why is that?

Maybe because now you can say it’s a “one carat diamond,” or maybe because now it’s three full digits. Who knows. But with diamonds, it’s all about feelings. This little quirk about the business is the sole reason there are so many poorly cut diamonds out there.

How Cutting Impacts Price

You could imagine very easily that if there’s a 20% price jump from a 0.99ct diamond to a 1.00ct diamond, the cutter who loses that 0.01ct trying to make a prettier stone will lose his job.

Perhaps with the nicer cut it will only be worth 15% less instead of 20%, but either way, it’s a big loss. This kind of price manipulation by maintaining weight categories has been taken to an extreme by many of the world’s largest diamond companies.

They will take rough diamonds with diameters that really should have only been used to make a 0.75ct-0.85ct diamond (with the proper cut to maximize brilliance), but instead will keep them over 0.96ct to sell them as 1ct diamonds to the major jewelry chains like Kay or Zales.

Even though they will have to sell these diamonds at steep discounts compared to well cut 1ct diamonds, they are still sold at a significant premium to well made 3/4ct diamonds.

The lesson here is, like above, not to get too attached to a diamond that’s within a certain carat weight category. A well cut 0.9 carat diamond will look significantly more beautiful than a poorly cut 1.00 carat diamond, all while costing either the same amount or slightly less.

For example, look at this 1 carat, H color, VS1 diamond. It has a relatively low cut grade (Good), and it clearly shows when you look at the diamond. Meanwhile, this ever-so-slightly smaller 0.90 carat diamond has a far better cut quality and looks more attractive at a similar price.

We’ve covered this topic in more detail in our guide to diamond cut quality. Cut is possibly the most important of the 4 Cs, making it something you’ll want to understand before you shop for any type of diamond.

How Color and Clarity Impacts Diamond Price

As we’ve covered below, a significant amount of the diamond pricing equation is based on the Rapaport Prices List, or Rap List — an industry price list that provides standardized pricing for different diamond color and clarity grades.

One interesting outcome of the entire business being based on the Rap List is that far too much weight is given to color and clarity in determining price.

As we mentioned above, cut is arguably the most important of the 4 Cs. In almost every case, the cut of a diamond will have a significantly bigger impact on its appearance than its color or clarity grade.

Objectively speaking, and G color SI1 clarity that is an ideal cut with a pleasantly laid out inclusion will be a prettier diamond than a G color VS2 clarity with an average cut. And a G SI1 super-ideal stone (like a Brian Gavin Signature stone) will be all the more beautiful.

If we continue with this case, lets say for a 1 ct diamond, a G SI1 that was an ideal cut (and everything else was fine), the price would be approximately “25 back,” or $6100*0.75 = $4575 per carat. But a G VS2 with an average cut might go for “35 back,” or $7200*0.65 = $4680.

By all accounts, the “25 back” SI1 is a much much prettier diamond than a “35 back” VS2, yet the VS2 is still more expensive.

Sounds confusing? It is. In simple terms, pricing standards used in the diamond industry often give too much weight to color and clarity when determining diamond pricing.

For a savvy buyer, this presents an opportunity to buy a diamond that’s aesthetically stunning but quite affordable due to its color and clarity grades — something we’ve explained in greater detail in our guides to diamond color and clarity.

This is why it is so crucial to have someone helping you along the way specifically regarding how to value the different factors that go into pricing a diamond. If someone knows what they are doing, they can really find tremendous value out there.

Diamond Price Chart

In terms of pricing, there are two basic categories of diamonds — those priced off of the Rapaport diamond price list and those that aren’t. The following is a recent update on diamond prices from Rapaport (in 100s for 1.00ct to 1.49ct diamonds):

IF VVSI VVS2 VSI VS2 SI1 SI2 SI3 I1 I2 I3

What is the Rapaport Price List?

According to Wikipedia, Martin Rapaport started as a cleaver and rough sorter in Antwerp, Belgium. In 1975 he began brokering rough and polished diamonds in New York City and, In 1978, created the Rapaport Prices List.

Since creating the price list, he’s also known for founding many businesses in the diamond industry, including an electronic trading network for traders RapNet and INDEX, and diamond-related news in print and web formats.

The Rapaport Diamond Report price list (“Rap List”) is released weekly on Fridays, however it does not necessarily change every week.

It is used as a baseline for pricing for basically all loose diamonds sold as single individual stones (as opposed to diamonds sold in parcels) generally SI3 or better in clarity and K or better in color (although the price list does offer prices for L and lower colors and I1 and lower clarities, they are rarely used in the industry).

How to Read the Rapaport Diamond Report

If you click on the image of a sample “Rap List,” you will see four separate grids. Each one is for a different size category. The four categories shown on this sample are 0.90-0.99, 1.00-1.49, 1.50-1.99, and 2.00-2.99.

Each grid is a matrix of color against clarity. To find the “Rap Price” for a given diamond, you need three pieces of information: the size category, the color, and the clarity.

Prices listed are always in hundreds. Let’s say, for example, that you have a 1.55ct H color SI1 clarity diamond. The “Rap Price” for that diamond would be $7,600 per carat. But finding the Rap Price for your diamond is only the beginning of pricing a diamond.

Why Companies Lose the Certificates

Rarely will you see a diamond with an I1 clarity grade sold with a certificate. As I discussed in the Diamond Clarity article, it is no small matter that James Allen has decided to sell GIA certified I1 diamonds online. There are very few places that do this.

Intelligent companies in the industry never sell GIA certified I1 diamonds because they know they can sell them for more without the certificate (and therefore without using the Rapaport diamond price list as the baseline).

Whenever they receive an I1 clarity grade for a diamond which they had intended to receive an SI2, they will simply throw out the certificate and pretend it didn’t exist.

Discount and Premium Prices

The real art of diamond pricing is figuring out the discount or premium to the Rap Price. In the vast majority of situations, diamonds trade at a discount to the Rap Price. It is this figure that two diamond dealers will haggle over.

Let’s stick with our 1.55 H color SI1 clarity diamond example.

Those three qualities (color, clarity, and weight) only bring you to the baseline. Now things become much more subjective. Factors that might come into play in determining the discount off of the Rap Price might include: Fluorescence, Cut, Inclusion quality, Luster of the diamond material, and Color Quality.

What is “20 Back” or “20 Below”?

If that diamond were an excellent cut and the SI1 was a beautiful SI1 that was way off on the side of the diamond and barely visible and the H color really looked like a G, and there was no fluorescence, then the diamond might trade at -20% or even -15% less than the Rap Price (in diamond jargon, this would be called “20 back” or “20 below”).

This is the figure that is argued over. So while a seller might try to sell this diamond at “15 back,” a buyer might only wish to buy it for “20 below.” To calculate the actual price, you need to reduce that percentage from the Rap Price.

In our example, “20 below” $7,600 per carat is $7,600 * (100%-20%), or $7,600 * 0.80, which comes to $6,080. Then you need to multiply that price by the weight to arrive at the final per diamond price ($6080 * 1.55 = $9,424).

Sweet Spots of Value

Now, take another look at the sample “Rap Sheet” from before. Take a close look. Notice anything odd? The differences between adjacent prices in each matrix are very far from being uniform.

For example, the difference between a 1ct G color VS2 clarity diamond and a 1ct H color VS2 clarity diamond is a full $1000. But the difference between the same G VS2 and a 1 ct F VS2 is only $500!

Don’t ask me why this is. The diamond business is rarely built on rhyme or reason. A skilled diamond dealer, though, can help you navigate these inconsistencies to find the sweet spots of value within this pricing grid.

In our case, for example, it’s clearly not worth it to upgrade from an H color VS2 clarity to a G color VS2 clarity since it costs so unreasonably much to make that upgrade. And anyway, as I mentioned in the Color article, color upgrades are rarely worth the money.

Diamond Pricing Alternatives to the Rap List

Over the years, there have been several attempts to create alternatives to the Rapaport price list in the industry. There is much to criticize about the Rap List.

Nobody knows what his methodology is and Martin Rapaport himself has financial interests in diamonds, so there’s a very clear conflict of interest. One of the most valiant recent efforts to create a new industry pricing standard came from the IDEX company.

IDEX

Similar to Rapaport, IDEX offers an online B2B industry diamond exchange in addition to publishing industry analysis. Unlike the Rap List, however, their diamond pricing tool, called the IDEX Diamond Price Report, is completely transparent about its methodology.

Their price list has gained the support of some major diamond dealers, but so far it has been met with much resistance in the broader market.

Diamond Retail Benchmark

In addition to the Diamond Price Report, IDEX publishes another consumer focused price list called the Diamond Retail Benchmark. Like the Rap list, the DRB offers a high-level standard price off of which should be applied a “discount” to arrive at the final consumer price.

The list is available here, but without knowing what “discount” should be applied in your specific case, it will be challenging to extract any usable information.

What about diamonds priced

without the Rapaport Price List?

Just about all other diamonds that are not certified, and therefore not sold as single diamonds, are sold according to a “parcel price.” This is a price per carat for the weight of diamonds purchased, irrespective of the number of diamonds selected.

Since there is no list dictating baseline prices, understanding these prices is far more nuanced and therefore requires years of experience to truly understand a parcel’s value.

Relying on Experts

In fact, at Leo Schachter, there were no employees who were experts in all shapes and sizes. Parcel diamond pricing is so complex and demanding of experience, that the company was broken up by size and shape to allow managers to become experts in their limited field.

There was a manager for princess and emerald cuts, round cuts 0.90ct and above, round cuts below 0.90ct, and other fancy shapes.

This is not so relevant for most of you, since you are better off buying a certified diamond unless you have someone you can trust completely who can sell you an uncertified diamond.

A diamond’s proportions are incredibly important. While it may seem like a hodgepodge of digits and percentages, if you ignore it, you may end up with a diamond that has no sparkle whatsoever. The color and clarity grades are simple enough that you may just overlook the proportions, but you do so at your own peril.

Take this one carat H VVS1 clarity round diamond for example. On the face of it, it is an incredible diamond that is a whopping 33% cheaper than this one carat H VVS1. But if you start looking at the proportions, you realize that the first diamond is poor value at any price.

Diamond proportion is the ratio and size of the diamond’s depth, width and table. The exact proportions like table and depth percentage play a huge role in the beauty of a diamond. Diamond proportion is an element of Diamond Cut and is critical to a stone’s brilliance and value. 

With ideal diamond proportions, a diamond takes in and reflects light well—causing brilliance and fire. This 1.26 carat round cut diamond is a stunning example of a diamond with ideal cut proportions. 

If a diamond is cut too shallow or too deep, light is lost out the sides and doesn’t reflect as well back to the eye. In other words, if a diamond’s proportions are poor, the diamond looks dull and lifeless. 

Because a diamond with ideal cut proportions offers more brilliance, the price also tends to be higher for these diamonds. Throughout our years of experience, we find that the higher price is worth it, because cut quality impacts the diamond’s beauty more than any other feature. That’s why we suggest spending a good amount of your engagement ring budget on Cut quality, over other features like Color and Clarity. 

Both of these are graded as Excellent Cut diamonds
One has a depth of 63.1% and we wouldn’t recommend
The other 58% and looks great!
Choose the diamond you like better and see if you are a pro!

How Diamond Proportion is calculated?

Diamond proportion is calculated using the dimensions of the table size, crown height and pavilion depth in relation to the diamond’s diameter. Each calculation describes the angles and ratios of the diamond’s precise cut. These aspects are universally measured in millimeters (mm) and/or percentages. The formulas for each specific component of a diamond’s proportions are listed below.

Diamond Table

Table percentage is calculated by dividing the table width (top surface area) by the diameter. For example, if the table facet is 3mm wide and the diameter is 5mm, the table percentage is 60%. 

  • If the table percentage is too low, light gets trapped inside the diamond and leaks out the sides of the diamond (instead of reflecting back through the table). 
  • If the table percentage is too high, light doesn’t reflect off of the diamond’s crown angles and facets—leaving the diamond looking dull. 

Diamond Width

Width is calculated by measuring from one end of the girdle (the diameter at its widest point) to the opposite end of the girdle.

  • Width is primarily used to determine the length to width ratio which denotes how proportionate the diamond is for its intended shape (i. e. rectangular vs. square). 
  • Length to width ratio is calculated by dividing the length of the diamond by its width. For instance, if a diamond has a length of 5mm and a width of 3mm, the length to width ratio is 1.67.

Diamond Depth

Depth percentage is calculated by dividing the depth of the diamond (its height) by its width. For example, if a diamond measures 3mm in depth and 4mm in width, the depth percentage is 75%. 

  • A diamond with a lower depth percentage usually appears larger due to its increased width, but often creates a dark appearance as the diamond doesn’t reflect light as well.
  • A diamond with too high of a depth percentage loses light out the bottom of the diamond, making it appear dull.

The table, depth and width all combine to impact how well a diamond refracts and reflects light. That’s why it’s essential to find a diamond with ideal cut proportions in each area. 

Factors affecting diamond proportion

There are several factors that impact a diamond’s proportions, including the table size and total depth. How well a diamond interacts with light is affected by the size, shape and angle of each facet. 

Here are the 10 main components that impact diamond proportion:

  • Table size: Length and width of a diamond’s table (top surface area)
  • Star length: Length of the angled facets adjacent to the table
  • Girdle thickness: Height of girdle (belt that divides the crown from the pavillion)
  • Lower girdle length: Width of the lower girdle—from the culet to where the facet connects to the girdle
  • Culet: Size of the culet (bottom tip of a diamond)
  • Total depth: Height of a diamond from culet to table
  • Pavilion depth: Height from culet to bottom of the girdle
  • Crown height: Height from the top of the girdle to the table
  • Pavilion angle: Angle of the pavillion from the bottom of girdle to the edge of a diamond pavilion
  • Crown angle: Angle of the crown from top of the girdle to edge of a diamond crown

Ideal Cut Diamond Proportions

The best diamond proportions allow light to refract and reflect back to your eyes. The ideal round diamond proportions are listed in the table below and based on expert recommendations. 

Best Diamond Proportions for Round Brilliant Diamonds<
Depth Percentage 59 to 62.6%
Table Percantage 54 to 57%
Girdle Thickness Thin to Slightly Thick
Culet None to Pointed
Length to Width Ratio 1.0 to 1.03

Each of these factors plays a role in the beauty and brilliance of the diamond. By staying within these ideal diamond proportions, you’ll end up with a stunning diamond that captures and reflects light. For example, this 1.32 carat round diamond is exceptionally brilliant because it’s well-proportioned. 

To find the best proportions, start by looking at GIA and AGS graded Excellent and Ideal cut diamonds. Narrow down your search to the recommendations above, as some Excellent and Ideal cut diamonds won’t meet these ranges. 

For help reviewing a specific diamond’s proportions, reach out to our experts.

Diamond Proportions Chart

Ideal diamond proportions depend on the shape, as each one interacts with light differently. As you look at diamonds, be sure you’re getting the best diamond proportions for the shape. To find these proportions, look at Excellent and Ideal cut diamonds, but remember that not all of them will meet the recommendations below. 

Best Diamond Proportions for Every Diamond Shape

Shape Depth % Table % Girdle Culet L to W Ratio
Round Brilliant Cut 59 – 62.6% 54 – 57% Thin-Slightly Thick None-Pointed 1.0 – 1.03
Princess Cut 68 – 74% 69 – 75% Thin-Slightly Thick None-Pointed 1. 0 – 1.04
Cushion Cut 61 –  68% < 68% Thin-Slightly Thick None-Pointed

1.0 – 1.08 (sq)

1.15 – 1.25 (rect)

Emerald Cut 61 – 68% 61 – 69% Thin-Slightly Thick None-Pointed

1.30 – 1.45

Asscher Cut 61 – 68% 61 – 69% Thin-Slightly Thick None-Pointed 1.0 – 1.05
Oval Cut < 63% 53 –  63% Thin-Slightly Thick None-Pointed 1.30 – 1.50
Pear Shape < 68% 53 –  65% Thin-Slightly Thick None-Pointed 1.45 – 1.75
Radiant Cut < 67% 61 –  69% Thin-Slightly Thick None-Pointed

1.0 – 1.05 (sq)

1.20 – 1.50 (rect)

Heart Shape 56 – 66% 56 – 62% Thin-Slightly Thick None-Pointed 1. 0 (or as close as possible)
Marquise Cut 58 – 62% 53 to 63% Thin-Slightly Thick None-Pointed 1.85 – 2.1

By staying within the recommended diamond proportions, you’ll narrow down your selection of diamonds to the very best. You’ll knock out diamonds that will look dull and lifeless in an engagement ring. 

Cut quality, including diamond proportions, is the most important factor in a diamond’s appearance. You’ll still want to pay attention to the other of the 4Cs: Color, Clarity and Carat.For help in choosing the right diamond, use the HD imagery on James Allen’s or Blue Nile’s websites, or reach out to our experts. We’ll take a look at the diamond you’re considering and make sure it gives you the most beauty for your budget.

Bottom Line Recommendation

Cut is possibly the most important of the 4Cs. If you ignore it, you can make an enormous mistake. For example, this diamond seems like a great find, as it is 5% cheaper than this diamond. In reality, the diamond will have no brilliance and is very poor value.

If you’re buying a round diamond, limit your selections to “Excellent” cut diamonds (if graded by GIA) or “Ideal” cut diamonds (if graded by AGS). If you’re buying any other shape diamond, it’s essential that you see a high quality image of the diamond before deciding to buy as fancy shape cut quality cannot be deciphered using certificate stats alone. Because of this, we recommend you stick with Blue Nile or James Allen.

When it comes to round diamonds, despite them all being uniform in shape, the difference between a well cut diamond and a poorly cut diamond is enormous. You can have something like this ridiculously brilliant diamond that runs circles around a poor cut like this one.  Despite the second one being a higher color grade, the first one is a much prettier diamond.

As always, if you’re unsure about any aspect of the diamond buying process, please feel free to contact us with your questions.

What is a “Diamond Cut”?

Diamond Cut is how well a diamond is cut and polished, including how well-proportioned the stone is, its depth and symmetry. Diamond Cut doesn’t refer to the shape of the diamond, such as an Oval or Pear Shape. Cut quality directly impacts the diamond’s beauty and brilliance. A well cut diamond is luminous and reflects white and colored light back to your eyes. A poorly cut diamond is dull instead of brilliant. 

Differences in Diamond Cut greatly impact beauty, aesthetic appeal and the value of a diamond. It is the most important of the 4Cs.

How GIA grades Diamond Cut Quality for Round diamonds

GIA diamond cutting grades for Round diamonds range from Excellent to Poor. Diamond cut grade is based on a number of factors including symmetry, polish, brilliance and fire. For the most brilliance and beauty, only consider Round Brilliant diamonds with an Excellent cut. Ensure the symmetry and polish of the diamond are either Excellent or Very Good.

The reality is that 55% of all Round diamonds receive an excellent cut grade from the GIA. About 25-30% of these “excellent” diamonds are not recommended. Our consultants review thousands of Excellent cut diamonds and find bad specs (depth, table and angles).

That’s why it’s important to look at the diamond cut grade on the GIA certificate, but to also review the diamond closely yourself or ask an expert. You don’t want to end up paying for an Excellent diamond that’s only mediocre.

Diamond Cut Grade Chart

A professional gemologist at the GIA reviews each diamond under magnification to determine the Cut grade. Here are the GIA diamond cut grades:

Excellent Excellent Cut Diamonds provide the highest level of fire and brilliance. Because almost all of the incoming light is reflected through the table, the diamond radiates with magnificent sparkle.
Very Good Very Good Cut Diamonds offer exceptional brilliance and fire. A large majority of the entering light reflects through the diamond’s table. To the naked eye, Very Good diamonds provide similar sparkle to those of Excellent grade.
Good Good Cut Diamonds showcase brilliance and sparkle, with much of the light reflecting through the table to the viewer’s eye. These diamonds provide beauty at a lower price point.
Fair Fair Cut Diamonds offer little brilliance, as light easily exits through the bottom and sides of the diamond. Diamonds of a Fair Cut may be a satisfactory choice for smaller carats and those acting as side stones.
Poor Poor Cut Diamonds yield nearly no sparkle, brilliance or fire. Entering light escapes from the sides and bottom of the diamond.

The AGS diamond cut grade chart also includes an Ideal grade. Cut quality is graded by the AGS as Ideal, Excellent, Very Good, Good, Fair or Poor. When looking at AGS diamonds, we recommend only considering Ideal cut diamonds for the best quality.

How Cut Grade Affects Price

Diamond cut prices are based on the precision and quality of the cut—primarily its proportions and symmetry. For example, this diamond is about as perfect a cut as you can get. The depth, table and all other proportions are as exact as can be. Because of that, you are paying a higher price for the diamond, even compared to a typical excellent cut diamond.

If the facets (the glossy flat surfaces of a diamond) are proportional, for instance, they refract and reflect light back to the eye in tremendous fashion. Diamonds that aren’t as precisely cut have facets and pavilions that do not refract and reflect light as spectacularly.

The amount of light return and brilliance found in an exceptionally cut diamond is worth the extra diamond cut price. Without brilliance and fire, a diamond is less than radiant—no matter the Carat weight or table size.

In other words, a diamond’s Cut is the quality that most significantly impacts its beauty. That’s why the higher diamond cut prices are worth every penny—and it’s better to spend more on Cut than on Color or Clarity.

For example, Brian Gavin offers a Signature collection called Hearts & Arrows which includes some of the best Cut diamonds on the market. For instance, this diamond has tremendous brilliance at an excellent price point. It would be perfect for a 1 carat diamond engagement ring.

If you’re working within a budget, we recommend forgoing a GIA grade in Color and Clarity to ensure you’re selecting an ideal cut diamond.

Factors affecting Diamond Cut (& Price)

The most important factor in a diamond’s value and price is its Cut quality. Many elements are involved in Cut quality including its proportions, facets, finishing details and ability to reflect light. The better these characterstics are as a whole, the higher the quality of the diamond, and in return, the higher the price. While Color and Clarity play a role in a diamond’s beauty, Cut is the most critical of the 4Cs.

Here are the main factors that affect the price of a diamond:

  • Proportions (table, width, depth)
  • Symmetrical facets (the mirrors, windows and steps of a diamond)
  • Brilliance (brightness of white light reflection)
  • Fire (dispersion of colored light)
  • Scintillation (the flashes of sparkle when light moves)
  • Finishing details (permanent treatment and polishing)

A diamond like this seems to be cheap if you are going by the color and clarity. But if you look at the proportions, this diamond is horrifically cut. It is incredibly deep and has a massive table. Under perfect lighting you may see some sparkle. But in real life scenarios this diamond will be devoid of any brilliance.

Diamond Proportions

To further understand the factors impacting Diamond Cut quality, let’s examine a diamond’s proportions, primarily its table, width and depth. These elements are universally measured and are excellent indicators of a diamond’s cut quality.

Diamond Cut Proportions directly affect a diamond’s ability to reflect light and provide brilliance. Proportions are based on the ratios between size, angle and shape of each diamond facet. Various combinations of these elements impact how the diamond will interact with light, which determines its overall beauty and lasting appeal (as well as its GIA grading).

About Diamond Table

Diamond table % is determined by dividing the width of the table (top surface area) by the width (diameter) of the diamond. For example, if the table facet is 3.5mm wide, and the diamond is 5mm wide, the table % is 70%.

If the table percentage is too large, light won’t reflect off of the diamond’s crown angles and facets. Vibrant reflections of color won’t be seen as the light will escape from the top of the diamond instead of reaching the eye.

If the table percentage is too low, light will remain trapped inside the diamond and be emitted through other parts of the diamond instead of to the eye.

The ideal table % depends heavily on the Diamond Shape. If you’re unsure of an excellent table % for your diamond, please
contact us and we will walk you through the options and factors.

About Diamond Width

A diamond’s width is determined by measuring from one end of its girdle (the diameter at its widest point) to the other end of the girdle.

The width is most important when it comes to determining length to width ratio, which signifies how proportionate the diamond is along with its intended shape (i.e. square vs. rectangular).

Length to width ratio is measured by dividing the length of the diamond by the width. For example, if a diamond has a length of 5mm and a width of 3mm, the length to width ratio is 1.67.

About Diamond Depth

Depth % refers to the height of the diamond, from the culet to the top of the table. Depth is measured in millimeters and percentage. By dividing the depth by the width, the depth % is achieved.

As an example, if a diamond is 4mm in depth and 4.5 mm in width, the depth percentage is 88.8%.

In most cases, a lower depth % of two equal carat diamonds will appear larger due to the increased width. On the other hand, a depth % that is too low can create a darker appearance as it will not reflect light as powerfully.

What happens when a Diamond Cut is too shallow?

When a Diamond Cut is too shallow, light hits the pavillion at a low angle. The light travels through the diamond and exits through the sides, instead of reflecting through the table and to your eyes.

While shallow cut diamonds may seem large based on their table size (they are also called Spready Diamonds), the escape of light at the bottom significantly reduces the diamond’s brilliance, sparkle and fire.

What happens when a Diamond Cut is too deep?

When a diamond is cut too deep, light hits the pavilion at a sharper angle, causing it to immediately reflect to another pavilion. The light is forced to retract and pass through the bottom of the diamond. As this happens, light is dulled and the diamond becomes less vibrant and radiant.

A Diamond Cut that is too deep also tends to look smaller than those of an ideal cut.

What is the best cut for a Diamond?

Simply put, a well cut diamond maximizes the light that strikes each pavilion. Instead of escaping through other parts of the diamond, light reflects back through the crown and table.

When it comes to determining the highest grade possible, GIA uses the term “excellent” while AGS (the inventory of the cut grade) uses the word “ideal.” These cuts are well proportioned with optimal facet angles, allowing the brilliance and fire to pass through the table for all to see.

For these reasons, excellent cuts are more valuable and more luminous. When buyers have a budget, we often advise choosing a smaller, well cut diamond as opposed to a larger carat that is poorly cut.

If you’re unsure of an ideal cut for your diamond, speak to an expert to walk you through the process.

Symmetrical facets

The facets of a diamond are the tiny mirrors that reflect light back to your eyes. Facets surround the diamond’s table. There are facets above the girdle and below the girdle. The pavilion (the part of the diamond below the girdle that reaches to the culet) is also made up of facets. A Round Brilliant diamond is cut with 58 facets total.

The size, placement and symmetry of the facets impact how well the diamond refracts and reflects light. A diamond with unproportioned facets, too many facets or not enough facets, can cause a less than ideal diamond. 

Brilliance

A diamond’s brilliance is the brightness of the white light reflection. When looking at a diamond face-up under light, it should reflect an abundance of white light. A diamond that’s not symmetrical, is cut too deep or too shallow, for example, looks dull instead of brilliant.  

Fire

A diamond’s fire is the amount of colored light that reflects off of the table and facets. Diamonds that are well cut not only have brillance but fire too. When looking at the diamond face-up under light—especially daylight—you should see colored light bouncing off of the diamond. If the diamond doesn’t exhibit colored light reflection, the diamond has a low amount of fire.

Scintillation

Scintillation of a diamond refers to the flashes of sparkle when light moves on the diamond’s table and facets. The scattering of light resembles a sparkle and is caused by the light and dark areas on the diamond’s surface.  A diamond with a large amount of scintillation is more desireable. A diamond without much scintillation can appear dull. 

Finishing details

The finishing details are the craftmanship of the diamond and include its permanent treatment and polishing. The polish of a diamond refers to the condition and quality of the facet surfaces. A diamond that is polished well creates a clear mirror for light to reflect off of. A diamond with a poor polish job looks dull because the facets don’t reflect light as vividly. 

Factors for Determining Diamond Cut Quality

Because Diamond Cut is an enormous element in determining the beauty and brilliance of any diamond, there are some complexities. Many factors play a role in how a diamond’s cut quality is determined.

The main factors impacting Diamond Cut Quality are:

  • Proportions: the ratios and sizes of the diamond’s depth, width and table
  • Symmetry: precision of the facets, mirrors, windows and steps
  • Polish: the shine and glow of the diamond surface

When you’re looking to see how well cut a diamond is, take note of how its facets and angles reflect light. Specifically, note how bright and sparkly the light return is when placed under a normal lamp.

You’ll want to gauge the diamond’s fire (the rainbow light of reflection) and its brilliance (colorless light and sparkle of the diamond). Be sure to also watch for any dark spots within the piece.

When a diamond is poorly cut (even if it has a high Color or Clarity grade), light will not reflect as well back to your eyes, making it a duller, more lifeless diamond.

Be sure to review the GIA cut grade on a diamond’s report, which will include ratings of Poor, Good, Very Good or Excellent.

What’s the difference between Diamond Cut and Diamond Shape?

The terms Diamond Cut and Diamond Shape have distinct meanings.

Diamond Shape describes the outline or figure of the diamond. For example, Pear Shaped and Round Brilliant refer to the shape appearance of the diamond.

Cut refers to the facets, symmetry, dimensions and reflective qualities of the diamond. A Heart Shaped Diamond, for instance, may be cut shallow or deep, dull or brilliant. The Heart Shape remains, while the Cut may differ significantly. The finer the cut, the greater the brilliance and fire of the diamond.

Our Recommendations For Buying The Right Diamond

When it comes to selecting an ideal diamond, we recommend a quality Diamond Cut over anything else. For GIA Certified Diamonds, we recommend choosing an Excellent cut grade. For AGS Certified Diamonds, choose an Ideal cut. When we search for a diamond, we filter more heavily on Cut. You can see our parameters by looking at this James Allen diamond search.

For Maximum Brilliance: Consider a Brian Gavin Signature cut. Brian is a leading industry expert in the field of cut optimization. His Signature cuts are on par with the famed Hearts on Fire brand—only far cheaper.

For Round Brilliant Cut Diamonds, don’t give any credence to an online vendor’s cut grade. Only focus on the GIA or AGS cut grade on the certificate.

In addition to reviewing a GIA or other grading report, be sure to look at the diamond yourself or have an expert assist you. Most importantly, ensure the diamond is appealing to you and your personal style and desires.

Our primary focus is making sure your diamond search is easy, simple and accurate. We want you to find the highest quality diamond while staying within your budget.

If you’d like assistance with finding and selecting a diamond, we’ll be happy to filter through the cuts and make recommendations for you.

BOTTOM LINE RECOMMENDATION

The price of lab-created diamonds have dropped in recent years, and we predict that trend will continue. With lab-created diamonds, the resale value is minimal. Jewelers don’t want to buy back lab-grown diamonds and if you try to sell them on eBay, you’ll get pennies on the dollar.

Having said that, if you’re intrigued with the idea of a lab-created stone and not bothered by seeing your diamond on sale for a lower price in the future, you can get more bang for your buck by going with a lab-created diamond. We recommend James Allen for lab-created diamonds. They’re IGI certified and their high-end photography allows you to view each diamond up close before purchase.

Another company you should check out is Clean Origin. They specialize in lab-created diamonds and have plenty of diamonds to offer.

OVERVIEW OF LAB-CREATED DIAMONDS

Lab-created diamonds are man-made diamonds that mirror the qualities and appearance of natural diamonds. These synthetic stones consist of carbon atom structures with the same chemical and visual characteristics of natural diamond crystal. For example, this stunning 3.01ct is a lab-created diamond. It’s a beautiful stone, but the value and resale value is incredibly low.

DIAMOND PRO DECLARATION

We believe diamonds are beautiful and a great choice for high-end jewelry, but we don’t buy into the marketing that you must buy a diamond for your engagement ring.

In other words, our goal isn’t to persuade you to buy a diamond. We’re here to help you get the best bang for your buck. We work to find the right balance of quality and size for your budget, all while avoiding rocks or pitfalls along the way.

We also agree that synthetic diamonds look exactly like natural diamonds. As long as we’re referring to lab-created diamonds (and not diamond simulants or cubic zirconia) they are “real” diamonds. I won’t go into the technical details of how diamonds are made because that’s not the issue. The main concern is value and wanting our readers to make smart, long-lasting purchases.

This article focuses on the value and prices of lab-created diamonds. If you’re interested in the ethical issues related to diamond buying, see this comprehensive article.

PRICES OF LAB-CREATED DIAMONDS

Just as with natural diamonds, the prices of lab-created diamonds fluctuate greatly. They can be as low as this 1.02 Carat for $1,600 or as expensive as this 5.23 Carat for $72,130.

Here are the main factors that impact the price of lab-created diamonds:

Shape: The most popular diamond shape is the round brilliant and also the most expensive. That’s partly because Round Cut diamonds offer the most brilliance and sparkle. After that, Oval Cuts and Asscher Cuts are the next most expensive.

Cut: A diamond’s cut impacts its beauty more than anything else. An ideal or excellent cut diamond will be more stunning and more expensive than a “Good” or “Very Good” cut diamond.

Carat Weight: The weight of the diamond, such as 1 or 2 Carats, affects its price. Typically, the heavier the stone, the more it will cost.

Color: Lab-created diamonds are graded by the IGI on a scale of D to Z. A D colored diamond is colorless, while a Z diamond has a noticeable yellow or brown tint. Diamonds with a better color grade will be more expensive, but the difference isn’t always noticeable. That’s why we recommend looking for a diamond in the G-J range, because they look colorless to the naked eye but cost far less than D, E, and F colored diamonds.

Clarity: When we talk about diamond clarity, we refer to how clean it is of blemishes and inclusions. Diamonds without inclusions will be more expensive than diamonds with noticeable imperfections. We recommend looking for VS1 and VS2 diamonds because they’ll be eye-clean but cost much less than FL or VVS diamonds.

Certification: The certification itself doesn’t increase or decrease a diamond’s price, but verifies what it is you are paying for. We recommend an IGI certificate for lab-created diamonds. The IGI offers the most extensive and reliable grading for lab-created diamonds. By choosing an IGI certificate, you’re ensuring that the diamond you’re getting is what the sellers say it is.

Take a look at these beautiful rings. If you replace the diamond with one of James Allen’s lab-created diamonds, you will save a nice chunk of cash(also check out the best places to buy lab-created diamonds here).

LAB-CREATED DIAMONDS VS. NATURAL DIAMONDS

Lab-created diamonds are made over the course of several weeks, while natural diamonds take billions of years to form. Lab-grown diamonds are created through a high-temperature carbon growing and compression process. Real diamonds are cut from a rough stone into the shape and carat weight that’s desired. Similarly, once a synthetic diamond is grown, a cutter forms the shape.

Placed side by side, a lab-created and a natural diamond look nearly identical. The price and value, however, differ—sometimes dramatically. For example, this 1.08 H VS2 lab-created diamond looks almost exactly like this 1.00ct H VS2 natural round diamond. The lab-created stone costs $3,640, while the natural diamond costs $5,280. That’s a 45% difference in price.

However, the lab-created diamond doesn’t retain any value. It can’t be resold to a jeweler and it won’t garner more than a few dollars on a site like eBay. On the other hand, the natural diamond can be resold for at least 50% of the original price—but potentially much more.

ARE LAB-CREATED DIAMONDS WORTH ANYTHING?

Lab-created diamonds have very little to no resale value. That means if you buy a lab-created diamond, you won’t be able to reap any part of what you paid for it. For example, if you bought this 1.20ct lab-created diamond, you’d have a beautiful stone, yet no jeweler will buy it back. If you try to sell it on eBay, you’ll get pennies on the dollar. From a value perspective, you’d need to buy a lab-created diamond at a massive discount to justify giving up the value retention of natural diamonds.

ARE LAB-GROWN DIAMONDS CHEAPER?

Lab-created diamonds are cheaper than natural diamonds but they’re a worse bang for your buck since there’s no resale value. As we explain in this article, you shouldn’t view your diamond as an investment, but you shouldn’t ignore its value entirely.

For example, let’s say an average natural diamond retains about 50% of its value after purchase. Eventually, the value of the diamond will rise (historically, diamond prices rise consistently). If you ever try to sell your diamond, you should get at least half (or possibly much more) of your original purchase price.

Here’s an example: this is a stunning 1.21ct diamond that we found. It’s an incredible value at $5,866. We asked companies that purchase diamonds how much they’d offer for it. They thought the diamond was stunning and were willing to pay $3,150. That’s 54% of the original purchase price. If diamond prices rise (as they historically do), the value only increases.

With a lab-created synthetic diamond, you would not have the same experience. For instance, this beautiful 1.33ct lab-created diamond costs $3,800. It’s cheaper than the similar natural diamond we just talked about. However, if you were to try and resell it, you might make $50 or less.

WHY ARE LAB-CREATED DIAMONDS SO EXPENSIVE?

The process for creating synthetic diamonds isn’t cheap. It requires specialized machinery, diamond-growing experts, diamond cutters, and more. Different than cubic zirconia or moissanite, lab-created diamonds involve either High Pressure-High Temperature (HPHT) or Chemical Vapor Deposition (CVD) processes. In order to multiply the carbon atoms and compress them into a diamond, they need time, innovative technology, and expertise. That’s why a beautiful 1.52 carat lab-created diamond will still cost you $6,020.

PLUMMETING VALUE OF LAB-CREATED DIAMONDS

In the last three years, the price changes in the lab-created market have been absolutely alarming. We recently did our own comparisons with products from the major online retailers of lab-created diamonds (MiaDonna, Diamond Foundry, and Brilliant Earth) to natural diamonds from James Allen.

We compared a GIA certified diamond from James Allen to an IGI certified diamond from Brilliant Earth. For lab-created diamonds, IGI Certified diamonds are the standard. The GIA, on the other hand, is what we recommend for natural diamonds. As we explain in our IGI article, it’s a much more “generous” laboratory, so we adjusted the grades accordingly.

Price Comparison: Beginning of 2017

For the lab-created stone, we chose Brilliant Earth’s 0.70 I VS1 IGI certified round diamond (no longer available) for $1,870. For the natural diamond, we used James Allen’s 0.70 J VS2 GIA certified round diamond for $1,590. Take a look at both diamonds to evaluate the quality for yourself. For these two identical diamonds, the lab-created choice was 25% more expensive than the natural diamond.

At the time, we also compared 12 other pairs of natural vs. lab-created diamonds. On average, the lab-created diamonds were 23% more expensive than similar real diamonds.

Just one year later, the difference is staggering.

Price Comparison: End of 2017 to 2021

From the example above, you can see that at the beginning of 2017, lab-created diamonds were actually higher priced than their natural diamond counterparts. By the end of 2017 leading up to today, there’s a very different landscape. Prices have dropped dramatically for man-made diamonds while prices for natural diamonds have increased slightly. The change is dramatic.

To show this more vividly, let’s take a look at more comparable diamonds from James Allen. With the lab-created diamond, you can find a 0.79 H VS2 round diamond for only $890. Through James Allen, you can find an identical natural diamond for $1,800. The natural diamond is now more expensive than the lab-created stone.

The natural diamond price change was expected. Diamond prices historically rise at a steady rate. That’s why you shouldn’t completely discount the “investment value” of a diamond.

On the other hand, the price of the lab-created diamond was alarming. In just one year, the price of the two identical diamonds dropped 30%. What’s worse is that the prices might drop even further.

It’s important to note that this isn’t a one-off comparison either. We analyzed several diamonds and the trend is the same. As an example, a one carat I VS lab-created diamond cost $4,100 at the beginning of 2017 and now is down to $2,850 (a 35% drop).

When doing these comparisons, we came upon a fascinating phenomenon that highlighted the alarming nature of the price change. When we reviewed at diamonds on Diamond Foundry (made famous by their movie-star investor), we noticed the prices of larger diamonds dropped at a faster rate than smaller stones. This distinction shows that the major roadblock in pricing is merely manufacturing expenses. The price will continue to fall because the technology will become less expensive. In other words, there is no inherent value in the product.

Overall, the price of lab-created diamonds has halved in the last two years according to a report published by Bain & Company.

LAB-CREATED GEMSTONE PRICES: DÉJÀ VU

The market for lab-created diamonds is eerily similar to what happened with lab-created emeralds. Emeralds were (and still are) one of the rarest precious gemstones in the world. Technology innovations allowed manufacturers to replicate a natural emerald and create a virtual copy.

I recently had the chance to talk with a former CEO of one of the largest lab-created emerald wholesalers (the CEO wishes to remain anonymous).

When lab-created emeralds burst on the scene in the early 1990s, people were excited and jumped on the bandwagon. These synthetic emeralds popped up in jewelry all across the United States. But it didn’t stop there.

“As with any technology, as the demand increases, the competition floods in. The prices for lab-created emeralds plummeted below any level we could have imagined. One day we were selling lab-created emeralds for hundreds of dollars per carat. The next day the price was in the $40 per carat range,” the former CEO recalls.

Soon after, people were buying synthetic emerald jewelry for $79 to $99. Lab-created emeralds were popular for a year or two, then the excitement faded away. You can still buy them, but they’re far from in-demand.

ARE LAB-CREATED DIAMONDS A FAIR COMPARISON?

Is it fair to compare lab-created emeralds to diamonds? Yes and no. From a technical perspective, it’s hard to imagine that the price of lab-created diamonds won’t continue to plummet. There’s no cap on supply and economies of scale, and innovations in technology continue to progress. These factors will all continue to force the price down.

Will lab-created diamonds fade away in popularity? That’s a trickier question. Emeralds are beautiful, no doubt about it. But the diamond market has positioned itself as a must-have when getting engaged (hats off to De Beers’ incredible marketing for the last 80 years).

If I were to pull out my crystal ball, I’d say that lab-created diamonds will thrive in the market for engagement rings priced under $1,000. Similar to the emerald market, no one that’s investing a hefty sum of money will be interested in a lab-created diamond. But if you’re looking at a dull, low-quality diamond from Zales or a lab-created diamond, many people might still opt for a lab-grown stone.

PURCHASING A LAB-CREATED DIAMOND TODAY

If you’re in the market for a diamond engagement ring, you can technically save big money by going with a lab-created diamond instead of a natural diamond. But you need to be prepared for the fact that it’ll be selling for a fraction of the price in the near future.

Other than sheer price, you might be interested in a lab-created diamond for other reasons. Perhaps you’re an engineer and are intrigued with the technical process of lab-created stones. Or maybe you’re looking for an ethical and environmentally-friendly choice.

BOTTOM LINE ON LAB-CREATED DIAMONDS

We’re not saying you should buy into De Beers’ marketing BS and choose a diamond for your engagement ring. But if you do opt for a diamond, you have a choice to make: if you are concerned with the long term value of your diamond, stick with natural. If you want the most WOW factor for your money, go for a lab-created diamond.

Don’t Overpay. Learn About Diamond Pricing Before You Shop

Thinking about buying a diamond? You have probably got a set budget for the engagement ring. And your goal is to get the best, biggest, and shiniest diamond on that budget.

We’re going to show you exactly how to do that.

Rule of thumb: A 1-carat diamond can cost as low as $2,000 and as high as $25,000. That means a middle-of-the-range diamond should be $11,000 – $12,000. Sounds simple, but that is overpaying. A good value, good quality 1 carat diamond should cost you around $4,500 – $6,000. We’ll explain below.

Bottom Line: Save money on color and clarity. You just need an eye-clean (flaws are not visible) diamond. We recommend H color and VS2 clarity diamonds for the sweet spot.

What to Know About Diamond Prices

In this article, we will discuss the industry secrets to diamond prices that jewelers don’t want you to know. But before we explain, here are a few things you absolutely need to know to get the best diamond for your money.

  • Quality (4C’s): The carat weight, cut, color, and clarity determines how much a diamond is worth. The more flawless and colorless the rock, the higher the prices.

    But here’s a secret: Save yourself money on color and clarity. These characteristics can’t usually be seen by the average person. All you need is a diamond that looks eye-clean and white. We recommend H color and VS2 or SI1 clarity as the sweet spot.

  • Certification: It’s extremely important that you only buy a diamond certified by a reputable lab. The certification is how you know that you paid for the quality advertised.

    We recommend diamonds certified by GIA and AGS, as these labs have the highest grading standards.

  • Where to Buy: Jeweler markup has the biggest effect on diamond pricing. The same quality stone can be priced many times higher when it comes in a trademark little blue box.

    To avoid paying high markup prices, we recommend shopping online at places like James Allen. Online retailers can cost as much as 40% less than big name jewelry stores.

Online diamond retailers (such as Blue Nile, James Allen and Whiteflash) allow you to custom design your own engagement ring with a loose diamond and setting. This also helps you save so you’re not limited to a store’s pre-set ring selection.

How Much is a 1 Carat Diamond?

© CreditDonkey

The average diamond size for engagement rings is around 1 carat. So, just how much can you expect to pay for a 1-carat diamond? Here is a general pricing guide:

Here’s a chart to show prices of 1.0 carat diamonds with different grades.

Diamond Price Color Clarity
1 Ct Round $9,000 E VVSI
1 Ct Round $7,500 F VVS2
1 Ct Round $6,500 G VS1
1 Ct Round $5,500 H VS2
1 Ct Round $4,000 I SI1

A good price for a 1 carat engagement ring is around $4,500 – $6,000 for an ideal cut diamond of H color and VS2 clarity. We will explain what cut, color and clarity means in this article.

This chart below shows the diamond price ranges of a 1-carat, round ideal-cut stone. Based on the color and clarity grades, you can easily see the vast pricing difference.

IF VVS1 VVS2 VS1 VS2 SI1 SI2
D $13-$16k $10-$13k $8k-$11k $7-$10k $6.5-$9k $5.5-$8k $4.5-$7k
E $11k $9-$11.5k $7.5-$10k $6.5-$9k $6-$8k $5-$7k $4.3-$6k
F $10-$11k $9-$10k $7.5-$9k $6-$9k $6-$8k $5-6.5k $4-$5.5k
G $8-$9.5k $6.5-$9k $6.5-$8k $6-$8k $5.5-$7.5k $5-$6k $4-$5k
H $6.3-$7.3k $6-$8k $5.5-$7k $5.5-$7k $5.3-$6.5k $4.7-$6k $4-$5k
I $5.7-$6.3k $5.2-$6.3k $5-$6k $5-$6k $4.7-$6k $4-$5.5k $3.5-$4.3k
J $5k $4.5-$5.5k $4-$5k $4-$5.3k $4-$5.3k $3.7-$4.7k $3.3-$4.3k

The highlighted boxes show our recommendations for best value. Color H and clarity of VS2 will get you a white-looking diamond that appears eye-clean. If you can find an eye-clean diamond at the SI1 clarity level, even better.

Store vs. online diamond prices: One thing to note is that we are using online jeweler prices. CreditDonkey conducted an independent market survey, where we found that online jewelers, such as Blue Nile and James Allen, offer pricing 32% to 50% cheaper than traditional big box jewelers. Online jewelers are able to offer much lower prices because of their low overhead. They also have wider selections.

How Much is a 2 Carat Diamond?

© CreditDonkey

A 2-carat diamond can cost as low as $7,000 and as high as over $60,000. The price depends on factors like diamond shape, color, clarity, and cut. A good value, good quality 2 carat diamond should cost you around $16,000 – $21,000.

Here is a price chart based on an ideal cut, round 2-carat diamond:

IF VVS1 VVS2 VS1 VS2 SI1 SI2
D $65-$73k $45-$60k $35-$55k $30-$50k $25-$40k $20-$30k $15-$25k
E $45-50k $35-$50k $30-$45k $23-$43k $20-$35k $17-$30k $14-$23k
F $35-$45k $30-$40k $26-$40k $22-$35k $20-$32k $17-25k $13-$22k
G $30-$40k $25-$35k $25-$32k $22-$32k $18-$28k $15-$25k $12-$20k
H $23-$30k $20-$30k $20-$30k $18-$28k $17-$25k $15-$23k $13-$21k
I $18-$22k $17-$24k $16-$22k $15-$22k $15-$20k $13-$20k $11-$18k
J $15-20k $13-$18k $13-$18k $13-$17k $12-$16k $10-$16k $10-$14k

The highlighted boxes are where we recommend you stay to get the best value – a diamond that appears white and eye-clean. Also, keep in mind that for fancy shapes, you can knock an extra 10% to 40% from these prices too.

How Much is a 3 Carat Diamond?

A 3-carat diamond can cost anywhere from $20k to $200k+. For the best value, we recommend a 3-carat diamond with color H and clarity VS2, which will cost around $35,000 – $50,000, depending on the shape.

How Diamond Prices are Calculated

Diamond prices are calculated per carat. The per-carat price increases exponentially as you move up in carat weight. This is because it is more rare to find bigger sized diamonds.

For example, a .25 carat round diamond starts at around $300 and a .5 carat round diamond starts at around $650. But a 1 carat round diamond jumps up all the way to $2,000+. For best value, we recommend staying just under half or whole carat weights (for example, go for 0.9 carat instead of 1 carat).

Diamond Price vs Carat © CreditDonkey

How to calculate diamond prices: Diamonds are priced per carat. A 0.5 carat diamond may cost $2,500 per carat. The price of that diamond would be $1,250 ($2,500 * 0.5). The per-carat cost increases as the weight and quality increases.

Did you know: Like diamonds, no two snowflakes are alike?

How to Calculate Price per Carat

Using price per carat, here’s how to calculate the actual diamond price:

  • If a 0.91 carat G SI1 stone is $5,500 per carat, the diamond price would be $5,005 (0.91 x $5,500)
  • If a 1.2 carat H VS2 stone is $7,200 per carat, the diamond price would be $8,640 (1.2 x $7,200)

Here’s how you can use the price per carat to determine best value:

Let’s say you’re deciding between two diamonds with the same color, clarity, and cut. Both look the same in size.

  • A 0.88 carat diamond that costs $5,000. The per carat price is $5,682 ($5,000/0.88)
  • A 0.82 carat diamond that costs $4,800. The per carat price is $5,853 ($4,800/0.82)

Even though the 2nd diamond costs less, it’s actually more per carat. So in this case, maybe you would think the first stone is the better value.

Note that to compare the per-carat price, you must be comparing apples to apples. You need to compare diamonds with the same cut, color, clarity, fluorescence, and lab certificate. You also need to look at actual appearance. This means whether flaws, tints, or haziness are visible.

Diamonds are priced per carat. Here’s what you get at lower carat weights.

  • How much is a 0.5 carat diamond? A good quality 0.5 carat diamond (H, VS2) is around $3,000 per carat. This means the diamond itself would be priced at $1,500 (0.5 * $3,000).
  • How much is a quarter of a carat diamond worth? A similar quality 0.25 carat diamond is around $2,000 per carat. So the diamond itself would cost $500 ($2,000 * 0.25).

Wholesale Diamond Prices

The Rapaport is a price list that’s intended to be a benchmark for global diamond pricing. It’s released every Friday and shows the current value of individual loose diamonds.

However, it’s not meant to be the ultimate diamond market price chart. The Rapaport merely serves as a baseline for sellers to establish their own pricing. It’s also used to keep up with changes in diamond pricing.

Tip: This report used to be available for only those in the diamond industry. But anyone now can buy the current report for $50 on the Rapaport website.

Here is an example of what a Rapaport looks like:

Sample Diamond Price Chart
Note: this chart is for illustrative purposes only and does not reflect actual diamond prices.

The Rapaport is shown as a grid comparing color and clarity of different carat ranges. The numbers are by the hundreds (43 = $4,300). The price listed is per-carat. You have to multiply your carat weight by the listed number to arrive at the final diamond price.

There are other similar reports:

  • RapNet: This is part of Rapaport’s Diamond Trading network. The prices listed here are the actual average asking price by sellers. This is only accessible to jewelers and dealers.
  • IDEX (International Diamond Exchange): The diamond prices listed on the IDEX report are higher than Rapaport’s. Diamond retailers would usually apply a discount when selling.

What’s Wrong with Industry Diamond Price Charts?

If there’s a whole chart about diamond prices, then why don’t we just use that?

The Rapaport chart makes diamond pricing seem so simple. But there are some problems with it, including:

  • It doesn’t take cut into account. Rapaport prices are only based on carat, color, and clarity. But cut is a very important factor. It affects how brilliant the diamond appears. And the pricing difference between different cut grades can be huge.
  • Different diamonds of the same grade can look very different. One SI2 diamond can be completely eye-clean while another one has visible flaws. One D colored diamond can be beautiful and clear while another looks hazy because of strong fluorescence. Of course the diamond that looks more beautiful will be sold at a higher price.
  • The price is high. Rapaport itself says the price listed is the “high asking price.” Retailers will generally apply a discount. Some jewelers will show you the Rapaport pricing and tell you that you’re getting a “good deal” because they’re selling for less. If you’re unfamiliar with diamond prices, you may be fooled into believing that.

Instead, use this article to learn how to get the biggest diamond with most sparkle for the best value. Learn about key factors that affect diamond prices. Then you’ll learn how to shop for diamonds online to save even more money and get the maximum value.

Do Diamond Prices Increase Over Time?

Maybe you’re wondering if a diamond is a good investment, and if the value will appreciate.

Historical data shows that diamond prices have increased on average 4% per year, over the past 10 years. This seems to be mostly keeping in line with inflation.

In the early 2000’s, an average-quality (H, VS2) 1-carat diamond was priced at $5,900 on Rapaport. In 2010, such a diamond was listed at $6,300, while it is $7,600 today.

However, just because a diamond’s retail price increases over time, it doesn’t mean that the diamond will have good resale value. Unfortunately, the resale market is weak.

As soon as you have purchased the diamond, the value has already gone down. And you will never be able to sell a diamond even close to what you paid. You shouldn’t count on a diamond as an investment.

There are only very specific types of diamonds that work as investment pieces. Natural fancy colored diamonds (like red, blue, pink, and canary yellow) are super rare and will appreciate over time. Similarly, large flawless, colorless diamonds also hold value, because of the super high quality. But the stone needs to be a larger carat size.

How to Get Lower Diamond Prices

The 4Cs

You’ve probably heard people talk about the 4Cs of diamonds: carat, cut, color, and clarity. This is a good place to start your diamond education.

The 4Cs combine to determine the overall beauty and price of a diamond. But that doesn’t mean each C carries equal weight.

Don’t waste your money. Some Cs are just not as important as the others, yet can cause a huge spike in price. If you don’t understand the basics, you could be spending a ton of money on features you can’t even appreciate.

Did you know? Don’t get too caught up on finding the most perfect diamond. Most women are not too concerned with that. 86% of women say the most important is the overall design of the engagement ring. So spend more effort to find out what kind of engagement ring style she will like best.

Some of the most common mistakes include:

  • Purchasing a diamond too high in color and clarity thinking it will make the diamond “shinier.”
  • Assuming that all diamonds are cut the same and therefore a better color and clarity is what’s needed.
  • Placing too high of a priority on carat size and then having to sacrifice in other areas to stay within budget, resulting in a dull, poor quality diamond.

Don’t make these mistakes. This guide will help you know what to prioritize and what you can “cheap out” on.

Carat – Is This the Most Important C?

Most people prioritize carat. That’s why it’s first on this list. However, in our opinion, it’s not necessarily the most important.

Carat is overall the most visible of the 4Cs. Most admirers say “Wow what a big rock!” instead of “Wow what a colorless and flawless rock!”

Unfortunately, it’s probably the one area you have the least control over. You probably already have a goal or “requirement” and can’t stray too far from it.

So, what is carat exactly? Carat refers to the weight of the diamond. One carat is equal to about 0.2 grams, which is roughly the weight of a paperclip. The heavier the carat weight, the larger the diamond.

Fun fact: The word “carat” comes from carob, a seed from the carob tree in the Mediterranean. These seeds have a very uniform weight. In the ancient days in Europe and the Middle East, they were used as a weight reference for traders – especially when dealing with gemstones where slight differences in weight are important.

Carat has the largest impact on diamond prices. Let’s look at how that happens. These diamonds all have a color of H, clarity of VS2, and an excellent cut. The difference is the carat weight.

The diamond price increases exponentially as the carat goes up. A 0.5 carat diamond is almost twice the price of a 0.4 carat. It again doubles when you go up to .75 and then again at 1 carat. This is because it gets more rare to find raw materials good enough to make larger diamonds.

Pro tip: The largest price jumps are at those desirable half-carat and whole-carat points. To get a better value, look for a diamond just slightly under the whole number.

For example, a 1-carat H, VS2 diamond costs $5,300. But a 0.9 carat diamond of the same specs costs $4,300 – a full thousand dollars less. Would anyone be able to tell the difference? it’s highly unlikely.

Here’s the math: A 1-carat round diamond is around 6.4-6.5 mm in diameter. But a 0.9-carat round diamond is 6.2-6.3 mm in diameter. This is literally just a difference of 0.2 mm at the most (equivalent to the thickness of a piece of paper). But you can save a lot. Don’t spend the money on something you can’t even see. You would need a size difference of 20% apart to be able to tell.

Why You Should Pay Attention to Cut

We’re saying this now and we’ll probably say it a lot more before the end of this article. Diamond cut is the MOST important factor, and you should NEVER skimp on it.

In fact, put whatever money you can save on other areas into the cut.

Cut is what makes the diamond shiny and sparkly. And it can literally make the diamond so sparkly that it hides inclusions and masks slight color.

Cut refers to proportion, symmetry, and polish – NOT shape. A rough diamond has no shine. A diamond only sparkles because of how it’s cut and how light bounces off each angle and facet. A poorly cut diamond will leak light and therefore appear dull. While a well-cut diamond will reflect light and look super brilliant.

Diamond Cut Scale © CreditDonkey

Aesthetically, cut also make a huge impact on beauty.

The above shows some examples of diamonds of different cut grades (Good / Very Good / Ideal / Super Ideal). You can easily see that the better the cut, the more beautiful the diamond.

That’s why it’s so important to get the best cut you can. Not only do you get a diamond that sparkles, you can also afford to down a bit in the other Cs.

In fact, an ideal cut can make the diamond appear larger.

Check out this example of 2 loose diamonds:

  • The diamond on the left is 1.00 carat and has a “good” cut. The surface area is 6.23×6.26mm. It costs $5,240.
  • The diamond on the right weighs in at 0.92 carats and has an “excellent” cut. The surface area is 6.23×6.2mm. It costs $4,720.

The two diamonds have the same surface area, so face up, they are both the exact same size. But because of the poorer cut of the first one, about 10% of the carat weight is wasted on the deep cut (just to hit the 1 carat mark). So, it’s not going to appear as brilliant as the other diamond.

For about $500 less, you can purchase the smaller diamond on the right. It may not hit that coveted 1 carat mark, but it looks just as large and will be a lot more sparkly.

Here’s an example of the diamond prices at different cuts (for a 1-carat, H, VS2 diamond):

The diamond price jumps quite a bit to the excellent cut, but this is an area where that extra money is well worth it as the difference in quality is very visible. If your budget is tighter, go down in the other Cs before you go down in cut.

Tip: Our favorite retailer for high-quality cut diamonds is Whiteflash. It has one of the largest inventories of ideal cut diamonds in the world. They are especially known for their signature A CUT ABOVE® super ideal cut diamonds. Each diamond comes with light performance imagery, so you can be confident in your purchase.

James Allen also has their own line of super ideal diamonds, called TrueHearts. Blue Nile’s premium collection of diamonds is called Astor by Blue Nile.

Color – Does It Matter?

A lot of people think that color and clarity affect how brilliant the diamond is. In fact, they have nothing to do with it.

However, color does still make an impact on the overall beauty of the ring.

Color refers to a slight yellow tint in colorless diamonds. The color ranges from D (completely colorless) to Z (obvious yellow/brown tint), though diamond retailers typically don’t sell anything less than K for engagement rings.

Diamond Color Scale © CreditDonkey

True colorless diamonds are extremely rare and therefore, priced at a premium. Most diamonds have a slight yellow tint, but most of the time, it’s undetectable to the naked eye.

The difference in price as you go up and down color grades is truly staggering. Here’s an idea of how wildly it swings. All these diamonds from James Allen are 1 carat with a clarity of VS2 and an excellent cut. The only difference is the color.

But here’s the thing: Most people cannot tell the difference between colorless and nearly-colorless diamonds. And there’s really no point in splurging on something with no visible difference.

To get the best value for your money, we recommend going with H. It’s in the near-colorless category, so the price is cheaper, but most people can’t see a yellow tint at all.

Expert tip: If you’re examining diamonds in person at a store and not sure whether a diamond will appear yellow (without all that bright store lighting), here’s a trick you can do. Fold a pure white business card in half and place the diamond in the crease. Look at it away from the spotlights. If you see any yellow at all, it will also appear yellow when set in white gold or platinum. This diamond is most likely at best a J or K.

The three diamonds below – from left to right – represent an F diamond (bottom of colorless range), an H diamond (middle of near-colorless range), and a J diamond (bottom of near-colorless range). Looking at them face up, can you really spot a difference?

The color of the setting can make a huge impact. H is a good choice for a platinum or white gold engagement ring. For yellow gold or rose gold bands, you can go down to a J or even K color diamond and it’ll still appear white against the band.

What if H is still out of your budget? Easy – go down in color even more. Personally, we’d rather have a J-colored diamond with an excellent cut than an H diamond with just a fair cut.

Clarity – Not As Important As You Think

Clarity refers to the flaws on a diamond. There are two types of flaws: inclusions (internal flaws) and blemishes (flaws on the surface).

It doesn’t actually really matter if your diamond contains flaws (most do). All you have to do is get a diamond with flaws you cannot see (called “eye-clean”). You don’t need a high clarity diamond for it to be eye-clean.

Clarity is last of the 4Cs on our list for the simple reason that you cannot see most flaws with the naked eye. Clarity grade is assigned based on what flaws can be seen under 10x magnification. In real life, nobody is going to examine your engagement ring that closely. A flaw would have to be pretty major to be visible to the casual observer.

We recommend VS2 as the most bang for your buck. The VS clarity grading refers to diamonds that have more noticeable flaws under magnification but most likely can’t be seen with the naked eye.

Here are some examples of eye-clean VS2 diamonds.

Diamond 1 / Diamond 2 / Diamond 3

VS2 diamonds are a generally safe bet that they will be eye-clean. If VS2 is out of your budget, it’s possible to find eye-clean diamonds in the SI1 and SI2 range, and even I1 if your budget is truly limited.

Let’s take a look at the price differences as we move up and down in clarity. All these diamonds are around 1 carat, an excellent cut, and a color of H.

As you can see, the difference in diamond prices as you increase in clarity is astounding.

Internally flawless diamonds are priced so high because of how rare they are. But just like with color, you will not be able to appreciate this because the difference isn’t visible. You shouldn’t pay $1,500 more just to have “flawless” written on a piece of paper.

Shape of the Diamond Makes a Difference Too

You might already know what shape your girl prefers or maybe you have no clue.

If it’s the latter, you may have some flexibility budget-wise here. An alternative shape also makes for more unique engagement rings.

Round diamonds are the most expensive and most traditional. Their popularity is due to the fact that round diamonds exhibit incredible brilliance. But if you think your girl could appreciate a unique shape, consider other diamond shapes as they are all cheaper than round.

  • Princess cut diamonds are the second most popular shape because they are almost as sparkly as round diamonds. Princess cut diamonds are edgy and contemporary, yet still feminine and delicate.
  • Oval diamonds put a modern, elegant twist on the classic round. It is for the girl who appreciates tradition but likes to express individuality. Oval diamonds are in the family of brilliant cuts, so they are close to round in terms of brilliance.
  • Other fancy cuts, such as pear and marquise, scream for attention. A woman drawn to these likes to stand out in a crowd. These shapes are also great because they often look larger than a round diamond of the same carat weight.
  • Step cuts, such as asscher and emerald, were very popular during the art deco period. These are for the sophisticated lady with vintage tastes.
  • Other square/rectangular cuts, such as radiant or cushion, will appeal to those who like the princess cut but want something a little less mainstream.

Pricewise, here’s how they compare, using the benchmark of 1 carat, H color, and VS1 clarity to control for the other Cs.

You can save as much as 20%-40% by going with a shape other than round. You can then put that money towards a larger stone, a fancier setting, or higher color/clarity grade.

Fancy-shaped diamonds are not given a cut grade by GIA, so they are a bit more challenging to buy. If you’re considering one of these alternate shapes, make sure you do the research and talk to a trustworthy jeweler who can tell you if the diamond is cut well or not. If you’re purchasing online, make sure you purchase from a website that shows you actual magnified photos of the stone (such as James Allen).

Certification: The Fifth C

© CreditDonkey

Certification is super important, so much so that it’s often thought of as the 5th C.

There are several diamond grading labs around the world: GIA, AGS, EGL, and IGI to name a few. These labs all have their own grading criteria and standards.

We recommend that you buy diamonds certified by GIA or AGS. These two labs are the most respected worldwide and have the highest, most consistent grading standards. For example, another lab may grade a diamond as VS2 clarity that would really be graded as an SI2 by GIA. Other labs may inflate their quality by as much as two whole grades. You’d be paying for an inferior product that just looks good on paper.

Diamonds certified by GIA and AGS are pricier (as much as 10-30%), because it is more expensive to receive a certification from them. But this is an area that you absolutely should not compromise on.

Did you know: The Federal Trade Commission legally allows a jeweler to be off by one color and clarity grade. So this means a jeweler can sell a diamond to you as a VS2 H, when it is really a SI1 I. This makes you think you are getting a better diamond and they can fetch a higher price. This is why you should never buy a diamond without a GIA or AGS report. These two labs have the most accurate grading practices.

Diamond Fluorescence Can Work In Your Favor

There is one last characteristic you need to know about – diamond fluorescence.

Fluorescence is when a diamond shows a soft glow under ultraviolet light (usually blue). This is caused by certain minerals in the diamond. This effect is totally natural, appearing in one third of all diamonds.

Usually, fluorescence doesn’t cause any negative effects on the appearance of a diamond. But since it’s generally seen as a “bad” thing, the good news for you is that a diamond with fluorescence can be priced 2-15% lower.

In diamonds with lower color grades (I and lower), the blue can counteract the slight yellow tint and improve the face-up color usually by one whole color grade. So you can buy a cheaper diamond with fluorescence in a lower color grade, and have it appear whiter.

Though there is usually no negative effect, you should know that for diamonds with a very high color grade (D-F), a strong-very strong fluorescence could cause a hazy appearance. But we wouldn’t recommend that you purchase a diamond in the colorless range anyway!

For an in-depth guide at diamond fluorescence, please read this article.

Natural vs. Lab Diamonds

We want to quickly mention lab created diamonds (or synthetic diamonds). This makes a huge difference in pricing.

So far, the examples you have seen are all for naturally mined diamonds. But lab diamonds are becoming more and more popular for engagement rings. Not only are they cheaper, they’re also eco conscious.

Lab created diamonds are the same as real diamonds with the same carbon structures. It’s just that the process is sped up in a controlled lab environment. Even gemologists can’t tell the difference.

Because they can be made in mass quantities in a lab, synthetic diamonds are much cheaper. They can be as much as 30-50% less than a real diamond of the same specs.

Are lab diamonds the same as treated diamonds?
No, they are very different. Treated diamonds are natural diamonds that have been enhanced. Typically, these will be poor quality diamonds treated to increase the color and/or clarity. A brown diamond can become white after a color enhancement. There are also clarity treatments to remove and fill flaws.

You can buy a treated diamond for up to 50% less. It sounds good, right? But be careful, because treatments can weaken the diamond and make it easier to damage. If a diamond has been treated, it should be properly disclosed on the report.

Other Factors that Affect Diamond Pricing

Besides diamond characteristics factors, there are a couple of other things that affect how retailers price their diamonds:

  • Jeweler markups: This has the biggest effect on diamond prices. Of course, prestigious brand names such as Tiffany and Harry Winston have high premiums. But popular mall jewelry stores have high markups as well. Stores with a physical location need to pay for a lot of overhead (the store itself, staff, etc., not to mention commission to salespeople), so these costs are passed onto customers. Online diamond retailers have less overhead, so they can sell their diamonds at a lower price.
  • Jeweler policies: Some jewelers will give you a lifetime warranty, free resizing, and 100% buy-back. These generous policies can be factored into the selling price of the diamond.

What the Experts Say

This gift is a symbol of eternal love to the most important person in your life. But buying the right one can be overwhelming.

As part of our series on engagement rings, CreditDonkey asked a panel of industry experts to answer readers’ most pressing questions. Here’s what they said:

Bottom Line

Here’s a quick cheat sheet for diamond buying:

  1. Go just below the 1 carat mark (or half carats) for a big drop in price – as much as 20%. We recommend checking out James Allen for affordable prices.
  2. Color and clarity do not affect the brilliance of the stone, so you don’t need to splurge on flawless and colorless rocks. Cut is what determines how sparkly it is, so don’t cheap out on this. Put whatever money you have into this area.
  3. A clarity of VS2 offers the most value for the money because most people won’t be able to see the small inclusions.
  4. A color of H is the best value for diamonds set in white gold or platinum bands.
  5. Getting a yellow or rose gold setting will save you more, because you can safely go down to a J or K diamond.
  6. Round diamonds are the shiniest but also the priciest. Consider a fancy shape for a more unique, yet budget friendly engagement ring.
  7. Look for a diamond lower in color grade with medium-strong fluorescence for a significant price drop and a whiter appearance at the same time.
  8. Multiple smaller diamonds cost a lot less than one single larger diamond. The halo setting is great for making a smaller center diamond appear huge on a budget.
  9. Only buy a diamond graded by GIA and AGS to ensure you receive the quality advertised.
  10. Online diamond stores offer prices as much as 50% less than big name jewelry retailers.

Do you feel ready to shop for an engagement ring now? Picking a diamond is part emotion and part science. It’s about hitting that balance of all 4Cs so that you get a stone that satisfies all your preferences while staying within your budget.

We hope this diamond price guide has given you a good starting point to understand diamonds and what to expect in cost. Please read our how to buy an engagement ring guide for more information.

0.5 Carat Diamond: Is It Worth Buying?

When inexperienced diamond buyers enter a jewelry store, they tend to ask for a 1-carat diamond, assuming they’ll save money on this smallest and not-so-popular gem. But the reality turns out to be completely opposite. To your surprise, this request identifies to any jeweler you’re a person to get left easily!

That’s because this phrase reveals your incompetence in several ways:

  • A 1-carat diamond is the most popular stone among all diamond carat categories.
  • One carat diamond is not the lightest one. There exists a 0.5-carat diamond, at least. Its weight is 100 milligrams, which is a half of 1-carat diamond weight. That’s why it’s frequently referred to as a ½ carat diamond.
  • Small carat weight doesn’t automatically mean the smallest size, because weight and size are two different diamond dimensions.

Can you imagine that: three serious mistakes in one innocent sentence! We don’t want you to be taken in — that’s why we created this guide on buying a half-carat diamond ring. Here, our diamond experts shared their buying tips, described how a 0.5-carat diamond ring price is formed, and offered their assistance to get the jewelry of your dreams! Keep reading not to miss these useful recommendations.

Buying Guide to 0.5-carat diamond: The most effective tips to picking a really good stone

If you think that’s hard to overprice a tiny 0.5-carat diamond, we’re here to disappoint you. Unfortunately, any carat weight alone doesn’t facilitate the evaluation. So, before you make an informed decision about the high-quality 0.5-carat diamonds, it’s reasonable to learn how to distinguish good stones from bad ones. For this, we’re here to explain the diamond ring basics and how they determine the appearance and quality of your choice.

3 things to invest in:

Thin shrinks (1.6-1.8 millimeters)

Highest cut and carat weight possible

Elongated diamond shape

To help you start your diamond shopping, here are the top 3 recommendations for picking a good 0.5-carat diamond:

  1. If you pick a 0.5 ct diamond size for the solitaire engagement ring design, pay close attention to the shrinks’ thickness. It should be 1.8 millimeters maximum, so even a half-carat diamond can become an accentuated diamond. Thin yet durable shrinks will help successfully eliminate the drawbacks of small size and carat weight.
  2. Invest in cut and carat number, not diamond color and clarity. When it comes to getting a real value-for-money for a 0.5-carat diamond, the downshifting of clarity and color will bring even less harm than it could happen in other carat categories. Thus, if you have free funds, it’s always better to choose a slightly higher carat number. In any case, the top diamond cut should become your priority.
  3. If diamond size matters, choose the shape that elongates it. Among the most suitable forms, go for marquise, oval, and pear options. The good news is these fancy shapes are cheaper than classic ones — and so, you’ll get an attractive half-carat diamond price with them.

Once you’re prepared to get the best engagement ring featuring a really good 0.5-carat diamond, it’s time to understand the difference between the elements of the 4C’s of a diamond and the way the diamond price is formed.

What’s the price of a 0.5-carat diamond

The question of diamond pricing is among the trickiest ones. And the reason is that many factors influence its value to a different extent.

On the most basic level, the price of a 0.5-carat diamond is calculated on the price per carat formula. It sets the value for each combination of cut, color, and clarity and multiplies the result on the exact carat weight the chosen diamond has. With this precondition, you can get the foreseeable price by getting the desired combination of diamond characteristics. And then, select the carat number that is affordable for you.

Together, these 4 factors have the title “the 4C’s of a diamond.” Once you get them, the exact diamond price will be easier to identify.

Price for a 0.5-carat diamond is formed on the basis of all the 4C’s of a diamond (not only carat weight but also clarity, color, and cut)

Among the other factors that affect the diamond prices, don’t forget to consider fluorescence, polish, length-to-width ratio, and diamond proportions. These factors are additional, though, while the above-mentioned 4C’s determine the initial cost of any diamond. Thus, if you are a diamond buyer, concentrate on the cut, color, clarity, carat weight, and shape — and leave the rest to diamond professionals.

To make a fair choice about a 0.5-carat diamond, apply one of these buying strategies:

  • Invest in a better cut and carat weight category,
  • Find the best clarity and color option,
  • Maximize the diamond size.

Basically, any good 0.5-carat diamond should be a combination of excellent cut, proper clarity and color, and a precisely selected diamond shape. Unfortunately, the reality can amend this ideal — because it’s not always possible to get all these three dimensions perfect and at once. Thus, you can play with these parameters in your particular case. In practice, you can concentrate on cut-carat, color-clarity, or shape maximization. But first, make sure you’ve got a good diamond that possesses the necessary quality minimum.

Last but not least, a diamond certificate is a must for any precious stone you buy. Nevertheless, it’s not enough to simply check the presence of this paper — you should also consider the diamond institution that issued it. In the diamond market, only GIA and AGS have a reputation you can rely on.

In short, the exact price of a 0.5-carat diamond (that can start from around $2,000 and reach almost $10,000) depends on its quality. And determining this parameter is possible by knowing the precise proportion of cut, clarity, and color, along with several other additional factors.

Is a 0.5-carat diamond big enough for an engagement ring

If you’re interested in size maximization, you can be safe that 0.5 ct diamond size looks big enough in an engagement ring. Specifically, the combination of an excellent sparkling cut and elongated diamond shape will make this stone shine in any circumstances. However, there can be problems with the diamond size if you invest heavily in color and clarity. That’s why we don’t recommend relying on this buying strategy at the expense of cut and shape.

Several 0.5-carat diamonds perfectly fit a pave engagement ring and earrings

When it comes to the exact diamond ring design, a couple of 0.5-carat diamonds look great in a three-stone combination. Also, customers frequently request this carat category for a pave engagement ring.

Another great option is to add 0.5-carat diamonds to a pair of earrings. Completing a carat, they look astonishing together. However, note that it’s not easy to get the pair of identical 0.5-carat diamonds — and so, you should invest in an excellent cut so both will look their size.

Clarity and color half-carat diamond ring

In a diamond, clarity stands for possible flaws and inclusions. The stone becomes less valuable because of them. To get a good option for a 0.5-carat diamond, go for Internally Flawless (FL and IF), Very Very Slightly Included (VVS1 and VVS2) or Very Slightly Included (VS1 and VS2) grades. They contain either no or very hardly identified imperfections. Also, note that both the number and placement of inclusions affect the diamond price.

Moreover, colorless diamonds may still have certain color grades. They range from D (completely colorless) to Z (visible yellowish or brownish hue). The more visible color tints are, the less valuable the diamond becomes. For a 0.5-carat diamond, we don’t recommend going below K diamond color.

Minimum requirements for a 0.5-carat diamond:

K color

VS2 clarity

Excellent cut

GIA certificate

½ carat diamond cut

Diamond cut is the parameter you shouldn’t sacrifice at any cost. It demonstrates the mastery of a diamond cutter in creating perfect proportions. You see this talent as brilliance, sparkle, and fire — and, of course, the rise in the amount which these diamonds cost. Notwithstanding, any diamond deserves nothing less than the best cut ever.

Among all the available diamond cuts, some brands distinguish a special category of premium cuts. These best items in the store have the ideal proportions — along with the great markup for their quality and the brand name.

Where to buy a half-carat diamond ring

Actually, determining the design of a 0.5-carat diamond ring is tricky. You need to find a true professional who has enough experience and knowledge to create a rich yet elegant setting to make this tiny stone reveal its sparkle and magnificence.

Diamond Prices (May 2021) – How Much is Your Diamond Worth? (REALLY)

How Much Are Diamonds Worth?


Diamond prices are complicated. Their true value is determined by dozens of factors. At least that’s what they often tell you. It’s true, but it really doesn’t have to be that complicated.


In this guide I’ll give you the all tools you need to calculate how much a diamond should cost, how much a diamond is worth – because as you probably know by now the two are not the same.
If there is one thing I learned during the past 14 years in the industry is that value and price are not the same. Far from it.

Diamond Price Chart

Actual Diamond Prices

















Diamond Carat Weight Price Per Carat Total Price * Recommended Diamond
0.50 Carat $1,100 – $7,690 $550 – $3,845 $1,000
0.75 Carat $1,810 – $8,800 $1,360 – $6,600 $2,400
1.00 Carat $1,910 – $15,650 $1,910 – $15,650 $4,280

5.00 Carat $8,430 – $70,370 $42,150 – $351,850 $105,010


* I may very well recommend a different diamond for each individual based on his/her specific needs (and I will explain below along with more actual diamond prices).


But since the reality is that 1 carat diamond prices range from $1,900 to $16,000 and 2 carat diamond prices range from $8,000 to $84,000 which is a HUGE difference so as a general rule of thumb, in today’s market, my recommendation for best value for money diamond would be G color, SI1 clarity, no fluorescence and at least very good cut, and very good polish & symmetry. Needless to say that all of the above prices refer to GIA certified diamonds

You are welcomed (and recommended) reading this 5 minutes pricing guide that will easily save you up to 50%.
However, if you are in a rush you can jump directly to:


Diamond Prices Explained



In short… A diamond’s value is set by its appeal.
Trying to regulate the industry and create a standard for diamond comparison, a methodology of diamond grading was set by the GIA and it is called the 4 C’s of diamonds.


The 4C’s stand for – Cut, Color, Clarity and Carat.
As I mentioned above, in reality it is more complicated than that and as diamond dealers we look on dozens of factors but this grading system does do the trick in providing good estimates for the diamond’s value by enabling us (and you) to compare similar diamonds.


The only thing missing is a chart that states how much does a diamond cost? How much is it worth? And here to fill in the void entered Martin Rapaport who invented the diamond price chart (sometimes also referred to as the diamond price list or diamonds price index)…


We’ll dwell into the diamond price chart below and I’ll explain how to use it and more important what are the chart’s flaws.
But before that, below you’ll find our diamond price calculator which will give indication as for current diamond prices (unlike in the chart which is a pricing index)

Diamond Price Calculator


Whether you are trying to assess the value of your diamond or looking for a diamond engagement ring and wonder how much a diamond is worth, this diamond price calculator is perfect for you.


We are analyzing hundreds of thousands of diamonds and by clicking the search button you will get all of the information you need


The price calculator’s defaults are set to 1 carat round diamond, G color, SI1 clarity with excellent cut and no fluorescence.
Without additional information, this is the best “out of the box” most cost-effective diamond to buy – the diamond with the best value.



How to Get the Best Diamond Value for the Least Amount of Money?


Now, I will not tell you (or sell you) that you can buy the same diamond for 50% less – it’s simply impossible (though there is a way to save about 20% which I’ll reveal at the very end of this article).
But I will tell you how to buy a similar looking diamond, one that you cannot tell the difference for 50% less – that is doable!


When professional diamanters are evaluating a diamond, they look at more than a dozen attributes.


BUT, with all the respect, these are things that even when diamonds are placed one next to the other – you won’t be able to tell the difference. Not to mention when the diamond is mounted. So why pay extra for things you cannot see?


Here are my tips and they work whether you are looking for a 1 carat diamond ring, a 2 carat or half a carat:


  1. Go Below Weight Classes


    If you are looking for a 1 carat diamond, consider 0.95ct. If 2.0 carat, consider 1.90ct. Same goes for fracture – if you were looking for half a carat then consider 0.45ct etc.


    Since diamond weight is one of the biggest and easiest ways to reduce costs – I’ve dedicated an entire section explaining the price per carat system at the end of this article.
    For now I’ll just say that diamonds are priced per carat AND the price per carat increases as the weight goes up – this means “double” increase.
    The result is that while a good quality 1 carat diamond will cost $6,000, the same quality diamond weighing 0.90-0.95 carat will cost about $4,000! That’s 33% discount!


    Search 0.9 carat Diamonds   
    Search 1 carat Diamonds


  2. Diamond Color


    Diamond color refers to how colorless the diamond is. D color is the ideal, the highest grading and Z is the lowest.
    On colors I and below you’d already start seeing yellowish tint.
    But unless you have superman’s vision you won’t be able to tell D color from an F color diamond or even my recommendation G color diamond.
    And the savings on a 1 carat diamond? 15%



  3. Diamond Clarity


    Diamonds are not perfect and clarity refers to the inclusions within them.
    There are various types of inclusions from black points to fractures.
    The grading tells us how big and how visible these inclusions are.


    Our goal should be getting diamonds with inclusions that are not visible to the naked eye, that unless a magnifying loupe is used you won’t be able to see them.
    This means we are aiming to an SI1 clarity diamond. And the savings compared to a Flawless diamond – 50%



  4. Diamond Shapes


    Are you familiar with the saying don’t be square? Well here I’m saying the opposite.


    Round diamonds are far more expensive than other shapes such as oval, cushion cut and even princess cut.
    Below you’ll find two examples of GIA 1 carat diamonds with G color and VS2 clarity.
    One is round and costs $6,300, the other is a cushion cut and it costs $3,500









  5. Diamond Cut – Never Settle


    This is where we don’t save! It is the only place where we tell you to make the extra effort and pay for an excellent cut diamond. The premium is not that high and we LOVE diamonds that sparkle!


The bottom line – a 1 carat round D Flawless diamond would cost $12,500 – $15,000.

And a 1 carat round diamond like the one I recommend, A G color, SI1 Clarity and Excellent cut would cost $6,000. (and a cushion cut about $3,500) Easy savings!


What is the Diamond Price Chart?


The diamond price chart, also known as Rapaport Price List or just “The List” is a matrix that provides a benchmark to a diamond’s value based on its 4 C’s.


Since a matrix is two dimensional and there are 4 C’s then there are several price charts – each is of a weight group. Also, Cut, even though often considered as most important C is not in the chart but is given weight by discounting diamonds that are poorly cut.


Here is the Rapaport price chart for round diamonds weighing 0-5 carats:

Diamond Price Chart by Rapaport


As you can see, each cube / each matrix represents a weight class.
On the left you have the diamond’s color and on the top you have the diamond’s clarity.
To know the diamond’s value, find your weight class’s matrix, crosscheck the row of your color with the column of your clarity and you get the result.
Just note that the results are in hundreds. Meaning that 89 is actually $8,900.
Also, more importantly, diamond prices are per carat! A system that has its own disadvantages, or advantages if you know how to use it (explanation below).

The Hidden Dangers in the Diamond Price Chart


The problem with the diamond price chart is not what’s in it but rather what’s not.
People tend to rely too much on the chart not knowing its limits.
Consider the following two diamonds below – which do you like better?


Both diamonds above have the exact same certificate – both are 1 carat diamonds, G color, excellent cut with vs2 clarity and…
The diamond price chart puts them both under the same value.
However, given the black inclusion in the center of the table of the right diamond, I assume you’d prefer getting (or giving…) the one on the left.
But, as you can imagine, you are not the only one to prefer the diamond on the left and therefore its value is indeed higher.
The 1 carat diamond on the left costs $7,600 and the diamond on the right costs $6,500…


As seen above, not all VS2 diamonds are alike and priced alike.
And this is a problem that was caused by something that does get representation on the chart.
What about attributes that are not on the chart?


  1. Cut Quality

    Cut is interesting and many claim it’s the most important of the 4 C’s and for a simple and logic reason – you want a diamond for its brilliance and sparkle.
    If its poorly cut – who cares of its color or even size?

    When considering diamond cut, aside for its measurements like depth and table size, you should also take into account polish & symmetry.
    The difference between a poorly cut diamond and an excellent cut diamond can be 30% when all other factors are the same.
    The diamond here is yet again 1 carat, G color, vs2 clarity only this time with Poor cut grading. The value now is $5,400


  2. Fluorescence

    Diamond fluorescence refers to a bluish glow some diamonds reflect under UV light. Since it is considered a flaw, a defect, a medium to strong fluorescence reduces the price of 10-20%.

  3. Certificate / Lab

    A diamond’s certificate is often referred as a 5th C.
    All of the above are true only if you know what you have or what you are looking at – and you should not trust the dealers word or expertise. When it comes to the certificate, you should only consider GIA. To make the point clear, when it comes to EGL vs GIA certificates – an EGL diamond may sell for as much as half the price of an equivalent GIA diamond.

Current Diamond Prices


Below you’ll find a list of actual diamond prices.
These prices are of diamonds of the highest value, diamonds that are:

  1. Excellent Cut
  2. Excellent Symmetry
  3. Very Good / Excellent Polish
  4. No Fluorescence


I chose these attributes both because in it is the only way to truly compare diamond prices and because in today’s market you may not want to waive these qualities.
With that in mind, you can always reduce the price by waiving a few of the above, the easiest and least affecting on appearance that does impact the price is the fluorescence.
Going to a faint to medium fluorescence will reduce the price by 5-15% and at the same time, may actually cause the diamond color to appear whiter (a positive side effect of fluorescence).


You should also remember that these are prices of loose diamonds.
The cost of the ring will set you back by another $300-$2,000 depending on whether you are going for the classic solitaire or a more expensive mount like a double halo and whether you go with gold or platinum (and even double if you’re buying a designer ring).


Take a look at these beautiful two 1 carat rings from James Allen:

1 Carat Diamond Prices


1 carat diamonds are as classic as it may get when it comes to engagement rings.
In fact, considering that the average engagement ring for the last few years is just beneath $6,000, 1 carat diamonds are probably as high as you can go.

The marked cell of a 1 carat diamond for $6,000 with G color and SI1 clarity is my recommendation for best value for money diamond.
It provides a good white diamond color that will work with both white gold and yellow gold and is basically as good as the eye can see.


The affordable alternative to a 1 carat diamond would be running a wider search of diamonds weighing 0.90-0.99ct that are still cut very good to excellent but may include fluorescence.
This search will get you a very similar looking diamond for approximately $4,350! And if you are going for yellow gold setting you can drop to H color diamond at $4,000.

2 Carat Diamond Prices


In recent years with the economic depression and the drop in demand for luxury goods, prices of diamonds declined (at least for a while) – especially in such in bigger more expensive diamonds.
As a result, the prices of 2 carat diamonds had decreased dramatically, in some cases 30% (though still very expensive) – So there was no surprise that we started feeling a stronger demand for 2 carat diamond rings.


To answer the question of how much a 2 carat diamond costs, check the chart below:

In order to make it easier, the above price chart is of total diamond prices and not per carat.
Since these are 2 carat diamonds and the price steps are HUGE price wise, I’ve recommended three options.
For $21,000 you get 2 carat diamond G SI1 – again the best value for money. However, due to the differences you may very well consider H SI1 or G SI2.
Keep in mind that the SI2 diamond may not be “eye clean” – especially in a 2 carat diamond. This needs to be verified.


On the affordable side of 2 carat diamonds, dropping to 1.80-1.90 carat diamond and allowing fluorescence may get you a G SI1 for $14,000-$15,000!


I don’t know if you’ve noticed, but my recommended 2 carat diamond costs more than three times than the equivalent 1 carat diamond. There is a reason for that.
For even better bigger savings, an advanced course if you will, if you are willing to break the mold of buying a perfectly weighing 1 carat diamond or a 2 carat diamond and buy slightly smaller carat diamonds like 0.90 carat or a 1.90 carat for an extra 10-20% discount – keep reading!


Deep dive into the price per carat system:

What Does Diamond Price Per Carat Mean?


Price per carat is the price of the diamond divided by its weight


The practical explanation is that if you see a diamond that is priced $5,000 per carat and it is half a carat what you’ll need to do is 0.50 * $5,000 = $2,500 for the diamond. And if the same diamond that costs $5,000 per carat weighs 1.50 carat then it means 1.50 * $5,000 = $7,500 for the diamond.

Comparing Prices of Apples to Apples and Diamonds to Diamonds


It may sound confusing or you may wonder why diamonds are priced this way but this is basically the same as fruits and vegetables are priced per lbs… This is extremely important because not all diamonds are the same and therefore should not be priced the same and the price per carat method allows you to better compare between two different diamonds.


Consider the following example – A man walks to the store looking for an engagement ring to his future wife.
He sees a beautiful classic solitaire ring with a center diamond weighing 1.10 carat with D color and VS1 clarity for $10,200.
Later, as he walks down the street he sees another store with the same ring only that the center diamond is 1.02 carat and they want $10,000.
Assuming that all other factors are the same, if we’ll ignore the cost of the ring itself (which should not cost more than $500) we will see that while the first diamond is about 8% “bigger” it costs only $200 more which is equivalent to 2%.
This means that the bigger diamond is the better deal. He pays a bit more and gets a lot more…

Weight Matters!

Price per carat drastically increases with slightest weight increment


It is important to know and understand that prices of diamonds increase with their scarcity.
The rarer the diamond the more expensive it is.
A high diamond color diamond costs more than a low color diamond not just because it is better color – but also because these are extremely hard to find.
Same goes for large diamonds. It is by far harder to find a gem quality diamond weighing 2 carats than a similar diamond weighing 1 carat.


As a result, the price per carat of a 2.00 carat diamond is higher than the price per carat of a 1 carat diamond.
In other words, two 1 carat diamonds cost less than one 2 carat diamond – in fact – far less…

How to Reduce Diamond Prices using the Price Per Carat System?


Let me ask you the following question – Would you rather buy a 1.00 carat diamond or a 0.99 carat diamond for 1% less? Same question regardng a 2.00 carat diamond and a 1.99 carat diamond for 0.50% less?


Most people would rather walk the extra mile (or pay the extra 0.50%-1%) to get a round weight number diamond or more correctly not to get the “just below” carat weight.


This is why ontop of what we mentioned above about the scarcity of diamonds causes higher prices, while diamonds are in fact priced per carat, the price per carat changes between weight steps or weight classes and as a result the prices of diamonds are not increasing linearly but rather exponentially – supply and demand. Meaning, that the price per carat of a 1 carat diamond is higher than the price per carat of a 0.99 carat diamond and thus the increase in total price is more than the 1% of the weight – much more.


Example with actual diamonds…:


At the time of writing these lines a 2 carat D VS1 diamond costs $40,000-$42,000 total, approximately $20,000 per carat.


A 1.90 carat D VS1 diamond costs $30,000 – which is $15,800 per carat – more than 20% less per carat and more than $10,000 total!!!


And in case you wonder, I doubt if you could find a 1.95 carat diamond because the price difference is so HUGE that the diamond manufacturer would rather settle on the cut quality than dropping from 2.00 carat to 1.95 – this “drop” will cost him $10,000… And the diamond cutter’s goal is not the brightest and most brilliant diamond but rather the most valuable one.

Carat Does NOT Mean Size!


Heavy men are not necessarily bigger.
On the same note, heavy diamonds are not necessarily bigger!
Just keep this in mind that “settling” on a diamond carat that is slightly less than originally intended (a “lighter” diamond) does not mean that it is smaller.


And therefore – my advice to you, if you are on a budget (and we all are), instead of settling on other factors of the 4 Cs (such as diamond color), you can step a little below the weight class that you had in mind and save A LOT of money. The weight steps which have an effect on the price per carat are: 0.50 carat, 0.75 carat, 1.00 carat, 1.50 carat, 2.00 carat, 3.00 carat, 4.00 carat, 5.00 carat and so on.

Frequently Asked Questions about Diamond Prices and Valuations

What is a 9 carat diamond worth?


Every once in a while a person finds a diamond in the Arkansas Crater of Diamonds and immediately the entire world is trying to figure how much that diamond is worth…
After all, everybody dreams about finding a diamond 😊


On September 25th 2020, a 9.07 carat diamond was found, the second largest diamond to ever being found at the Crater.


There is very little that is known about this diamond at the moment. But a mid-level quality 9 carat diamond would be worth around $100,000-$250,000.


However, considering that a diamond can easily lose about 50% of it’s weight during the polishing procedure, it brings us to a 4.5-5.5 carat diamond which would place this specific catch in the $40,000-$60,000 price range.

The diamond is one of the most popular stones in the world. This stone has won the love of buyers due to its amazing strength, inner radiance and unique brilliance.

A diamond is a cut diamond, but not every cut diamond deserves to be called a diamond.

The dispersion of light on the facets of a diamond, which means its cost per carat, depends on the shape of the cut and its purity.The main types of diamond cuts have been designed to emphasize the natural properties of the stone, which is why a quality cut is so important.

Determining how many carats there are in a diamond

There is an exact system of classification and evaluation of diamonds in Russia, with which you can describe a gem in detail and find out what the price of a stone will be.

The average price per carat of a diamond in rubles will not differ much from the global one, it may change due to changes in the exchange rate.

According to the Russian quality assessment system, the price of a diamond will be influenced by:

  • the quality and method of cutting a mineral affects the shine and appearance of the stone;
  • weight of the cut mineral. The price of a faceted mineral will directly depend on the weight and on the size category in which the stone falls. It can be considered small, up to 0.29 carats, medium, up to 0.99 carats. Diamonds over 1 carat are already considered large. The cost of a large diamond in rubles can reach 600 thousand per carat.The price of a 5-carat diamond will be significantly higher than a one-carat stone;
  • purity. Natural minerals often have different inclusions. The scale for assessing the purity of a stone according to GOST defines several types of purity. The average price for a stone will be the higher, the less inclusions the stone contains and they are smaller in size;
  • color. The most expensive will be colorless diamonds. Prices will decline with increasing yellow tint. But sometimes dark stone colors will be more expensive than light ones.This is true of black diamonds, which have recently gained popularity in the gemstone market.

Black diamonds – value or a tribute to fashion?

More recently, the fashion for black diamonds has taken over the world. Such stones look very noble, although they do not have a strong luster like their colorless counterparts.

There are many legends and controversies around black diamonds. Someone thinks that they should be more expensive than diamonds of ordinary colors, someone does not see jewelry value in them.Let’s figure out how much a black diamond will cost, what its average price is connected with, and whether its frenzied popularity is justified.

The Whole Truth About Carbonado

It is often described on the Internet that black diamonds are derived from the rare black carbonado diamond. If you have ever seen a carbonado even in a photograph, you will immediately understand that this opinion is wrong.

Carbonado really has inclusions of diamond and is very similar in hardness to this stone, but due to the porous structure, carbonado does not shine at all and cannot be cut.They tried to grind the mineral and turn it into a precious crystal, but not a single attempt has been successful. This stone is used only in industry.

The cost of black diamonds

Diamonds are preferred to be made from what needs to be cut – from monocrystalline black or dark diamonds. Black diamonds weighing more than 5 carats are really rare in nature and diamonds from them can be very expensive.

The largest black diamond named for the anniversary of the city of Amsterdam.It weighs 33.74 carats and costs about $ 10,500 per carat.

The price of a quality black diamond about a carat in size can reach about $ 3000 per unit of weight. The cost of an average quality diamond will be only about $ 150-600 per 1 carat.

There are very cheap varieties of black diamonds. Such stones are obtained by dyeing and processing dark diamonds, stones with visible defects and other substandard ones. Such stones, especially if they are small, can cost $ 10-20 per carat.You can find out what the origin and grade of the mineral you like can be found in the certificate, which necessarily accompanies any gem.

    90,000 Colored diamond prices fell 0.7% in Q3 2020

    Photo: FCRF

    The Fancy Color Research Foundation (FCRF) has announced the results of its Q3 2020 Fancy Color Diamond Index (FCDI).For two long quarters, due to restrictions due to the COVID-19 pandemic, the FCRF could not conduct a price study and now has published the first index in 2020, the fund said in a press release.
    On average, colored diamond prices fell 0.7%, but with the rise in transactions in the third quarter of 2020, FCDI has shown overall stability against this chaotic period.
    Most categories of stones experienced declines of less than 1%, while yellow diamonds showed less falls than blue and pink diamonds.The GIA Vivid Gemstone category across all color segments showed price stability, down 0.1% compared to the Fancy (-1.1%) and Fancy Intense (-0.9%) categories.
    Yellow diamonds showed the smallest decline in the third quarter – 0.3%. The category that saw significant growth were the 8-carat Fancy Intense Yellow diamonds, up 1.0%. The 5-carat Fancy Intense Yellow category of stones, on the other hand, dropped 2.4% in price.
    Overall, in the third quarter of 2020, pink diamond prices declined 0.8%. The Fancy Vivid Pink category saw the biggest price drop as 10-carat diamonds fell 3.5%, but also saw the biggest price increase as 1.5-carat diamonds rose 1.6%.
    As with pink diamonds, overall blue diamond prices declined 0.8% in the third quarter. The 1.5-carat stone category dropped 1.8% in price, while the Fancy Vivid Blue 2-carat category increased in price by 1.5%.
    FCRF Advisory Board Member Oren Schneider said in this regard: “While the diamond trade has not yet fully returned to its pre-COVID ‘normal’, we are clearly seeing an increase in fancy color diamond activity as restrictions. We look forward to further improving the business environment in 2021. ”

    Why diamonds are valued – Evora.ru

    Without exception, all women dream of diamond jewelry. Not everyone can afford to make such a gift, although there is always an alternative. Diamonds are expensive stones, but crystals of the same size can vary significantly in price. What’s the point? The cost of diamonds depends, first of all, on their quality parameters: weight, color, clarity and cut. This classification is usually called “4C”.

    In the Evora online jewelry store you can find the following diamond items:

    The key to evaluating diamonds is their carat weight.It is clear that the more weight, the more expensive the stone. As you know, 1 carat is equivalent to 0.2 grams. The carat division scale consists of one hundred units. The weight of a gem is measured on a special scale that determines the weight with an accuracy of 0.01 carats. There are three weight categories of diamonds: small, medium and large. Large stones weigh more than one carat, medium – 0.3-0.99, small less than 0.29, stones weighing less than 0.01 carat are considered crumb. It should be noted that carats measure the weight of the diamond, not the size.Let’s say you decide to purchase a diamond ring. According to the gemological description, the weight of the stone is 0.03 carats, in accordance with the metric system, its diameter will be a little more than 2 millimeters, the correspondence is approximate, but it is quite possible to imagine how the stone will look. Of course, the more carats, the larger the crystal, for example, a 5 carat stone will be about 11 mm in diameter. Approximate parameters in relation to weight – diameter are given in the table.

    Table 1.Approximate Weight / Diameter Ratio for Diamonds
    Weight / Carat Diameter / mm
    0.03 2.0
    0.10 3.0
    0.30 4, 3
    0.50 5.2
    1.0 6.5
    1.50 7.5
    2.0 8.2
    3.0 9.4

    The mass of a diamond, assuming a standard round cut, can be calculated using the following formula: M / mass / = ( 2D / diameter /) x H / height / x 0.0061 .As a rule, stones of the first weight category go under the hammer. Stones weighing more than 25 carats have their own names and are known all over the world. Not everyone can buy such a unique one, since the price will shock.

    The size of the stone, of course, matters, but there are other, no less important, characteristics, one of them is the color of the stone. Diamonds are believed to be colorless. Indeed, such stones exist and are very expensive, but, unfortunately, there are very few of them. For the most part, diamonds – future diamonds – have shades of different intensities, which are determined by a color scale separately for each category of stones.You can find out the characteristics of diamonds based on the Diamond Color Scale or the Diamond Color Chart.

    Table 2. Color scale for diamonds

    9019 blue 1

    Characteristics of stones Group no.
    Small stones
    Absolutely colorless 1
    With a slight tint 2
    , purple, gray and brown 3
    Visible tints of yellow, lemon, green, aquamarine or gray 4
    Yellow, with yellow, green, lemon colored throughout the stone 5
    Brown tint 6
    Brown and tan color 7
    Medium and large stones
    Absolutely colorless higher Colorless 2
    With a barely noticeable shade 3
    With a slight shade of yellowness 4
    With the presence of small yellowish, greenish, aquamarine, purple, gray and slight brown shades C visible shades of yellow, green, aquamarine and gray 6
    With clearly visible yellow, green, aquamarine, gray and lemon shades 7
    Extremely weak, weak, light yellow colors 8 (1-5)
    Weak, lightly colored brown and dark brown 9 (1-4)

    Color parameters of diamonds are usually evaluated according to two classifications: according to domestic and international – system GIA (Gemological Institute of America).Colorless diamonds are especially valued according to both classifications. If an average diamond of 0.3 carats in a piece of jewelry is assigned to group 4 according to the color scale, it means that it has a slight tint of yellowness. This does not mean at all that the stone is of poor quality, of course not, just its cost will be lower than the same size of the stone, but absolutely colorless.

    We are smoothly moving on to one of the most important parameters in evaluating diamonds – their clarity. This characteristic is expressed in the presence or absence of other natural inclusions and defects in the diamond structure.It is clear that the fewer there are, the more valuable the mineral. Today, it is almost impossible to find completely transparent stones in nature, which is why their prices are unusually high. Defects in diamonds can be both internal and external, they are determined using a special microscope or a magnifying glass with a tenfold magnification, using the international and Russian assessment systems. The scale of measuring the purity usually includes 11 items (numbers), characterizing the stone in terms of the presence of foreign inclusions.

    Table 3. Measurements of diamond clarity

    there are small insignificant inclusions

    Purity / No. Characteristics of stones
    1 stone absolutely clean
    2, 3, 4 very small inclusions are present
    5.6
    7.8 there are small noticeable inclusions
    9.10.11 inclusions are visible with the naked eye

    It is clear that the lower the purity number, the more valuable the stone …If you are offered a piece with a stone of purity 5, then there are “very small minor inclusions” in the diamond, which will certainly affect its value. For many buyers, the best option is to buy a stone of purity 2 or 3, or even better 1. By the way, in our store there are jewelry inlaid with stones with purity – 1. To establish the degree of transparency, jewelers determine the nature of these defects, their size and location, since surface imperfections can be removed by sanding.If no defects are found upon examination, then the stone is recognized as a “diamond of pure water”. Given its large size and absolute colorlessness, it is a very expensive stone, and, by right, is considered the “Emperor of all stones”.

    The main principle in evaluating a diamond is the cut – not the form obtained, but the quality of workmanship. The same stones with different cut quality are completely different from each other, since the brilliance and play of color depends on how proportionally and accurately the cut of a diamond is made.The most popular and expensive diamonds are considered to be round-cut diamonds with 57 facets, which, with strict observance of all proportions, can reflect all the light falling on them. The ideal cut is indicated by the letter A, good – B, satisfactory – C, low cut quality is indicated by the letter G. Small fancy-cut stones with 17 facets are evaluated only in categories A and B. In addition to the round, there are wedge (oval, pear, heart, marquise and others), as well as stepped (baguette, emerald, etc.)) types of fancy cuts. It should be noted that the higher the quality of the stone, the brighter it shines and plays in the rays of light.

    As a rule, diamond grading is unified; four parameters are always taken into account when calculating the price – weight, color, clarity and cut. Based on these parameters, you can determine the value of the stone, judge its differences among others. That is, in principle, the answer to the question: why the same stones have different values.

    diamonds | Brilliant price. 1 carat diamond cost

    There are a lot of people who want to buy 1 carat diamond , and before answering the question how to buy
    1 carat diamonds is more profitable and more reliable, let’s figure out what it is.

    Diamond price . Let’s take a closer look at Carats for gold and diamonds are two different concepts that are completely unrelated to each other.
    The carats of precious metals indicated on the frame are the number of gold fractions in the alloy to the total weight,
    taken for 24.For example, 18 carat gold is an alloy in which 18/24 shares, that is, 3/4 is pure
    gold, and 6/24, that is, ¼ – some other metals. Therefore, if you receive from a loved one
    gold ring with diamond and proudly indicated on the certificate – 18 carats, do not assume that this is
    diamond 18 ct. Diamonds of 18 carats are rare, although I had the pleasure of participating
    in Antwerp a few years ago in a transaction of such a stone, which, by the way, belonged to my namesake, Maxim.The carats of a diamond are not proportion, but weight. I probably won’t reveal the secret if I say that 1 carat is
    the weight of a grain of a plant that has long been used in the Middle East for weighing precious stones and
    spices. Round diamond 1 carat – about 0.2 grams, or, with a round stone – a diamond
    with a diameter of about 6.5 mm, when measured at its widest part – on the rudist. It should be noted that
    that the weight of the stone grows rapidly with a relatively insignificant increase in diameter.4 mm – 0.25
    carats, 5 mm – 0.5 carats, 6.5 mm – 1 carat, 8 mm – 2 carats, 9.4 mm – 3 carats. I remind you that all this
    approximate dimensions, valid only for a round cut with its good quality. Unfortunately
    for consumers, diamonds are priced by weight. Moreover, if for the convenience of understanding,
    diamonds are divided into three categories: small – up to 0.30 carats (this is a diameter of 4.2 mm), medium – from 0.30 to
    1 carat and large – from 1 carat, then in the Rapaport table, which is used all over the world for
    orientation 1 carat diamond cost , division is more fractional.This is the table that gives
    approximate retail prices for diamonds based on weight, clarity and color. Other characteristics
    stones are also taken into account, but not in direct form, but in the form of coefficients. To find out the diamond price according to this table, you need to determine which category by weight it falls into, there are 18 of them.
    : 0.30- 0.39, 0.40-0.49, 0.50-0.69, 0.70 – 0.89, 0.90-0.99, 1.00-1.49, 1.50-1.99, 2.00-2.99 and so on.
    You understand?! Differences in weight are insignificant, 0.89 and 1.00, in diameter – generally unobtrusive
    untrained eye – 6.3 mm and 6.5 mm, but the price change – more than 2 times! For example,
    with perfect purity and color – 100 and 245 hundreds of dollars, respectively. And this one is essential
    the difference in price between stones of almost the same weight 0.99 and 1 carat diamond price pushes
    cutters, whose wages directly depend on the value of the stones they produce,
    to an irresistible desire to hold out the weight to the desired diamond 1 carat .By what means? Due to the deterioration
    cut quality. And your long-awaited and expensive diamond 1 carat will be pure, white, but not
    will shine like a 0.95 carat stone made from this diamond would shine. That’s why when
    if you want to buy diamond , do not spare the money, consult a professional. Only
    a professional diamond appraiser or independent gemologist can, given the realities of your budget and
    Your goals, suggest the best option.For example, if you are craving to buy a engagement ring with
    diamond
    , it is wiser, with a lack of funds, to buy a stone a little less, but with an excellent cut
    and in a unique frame, the effect will be stronger. If your goal is primarily an investment of money and only
    secondary – the desire to buy a ring with a diamond and wear it, I would advise to buy
    brilliant 1 ct . But what color and purity to choose – we will decide personally, if
    want to take my advice.From your goals we will also choose the place of purchase – you can
    buy from a dealer of the Antwerp Diamond Exchange, which also has its own retail store,
    or you can buy at a store that specializes in interesting, unique frames.
