● Diamond Value Calculator

While diamonds are all unique and incredibly rare to find, over the years the diamond pricing methods have become largely standardized so that all diamond professionals can calculate the actual diamond value just looking at the diamond’s characteristics. While this approach will give you a decent estimate of what the total value will be, there might still be a little difference when it comes to actually buying or selling your diamond depending on your negotiations with the diamond buyer or seller of that particular diamond and of course because diamonds like all other precious gemstones have different prices based on market conditions. The price difference isn’t significant, but it’s good to keep it in consideration.

What we mean by market conditions is the variation in price based on whether that particular diamond is currently in high demand, like princess cuts and cushion cuts in 2015, and if that particular diamond is especially rare to find, like large colored diamonds or large flawless diamonds perfectly cut by the diamond cutters.

Cost of diamonds: What are the 4Cs?

As you can see on the diamond pricing chart above, different carat sizes have specific price lists, where they are further categorized based on clarity and color. For that reason, before we go into calculations to know the diamond cost, it is important to start at the beginning at look what carat, color, clarity and cut really refers to. In the business, we refer to these four essential characteristics of diamonds as the 4Cs. Each “C” plays a part in a diamond’s beauty, rarity and therefore price.

● Carat, Factor 1

The first C is carat, which is a unit of weight. Often enough, people use carat to refer to the size of a diamond but this is not correct. While it is true that a 2 carat is bigger than a 1 carat, it’s not exactly double the size, and a 3 carat is not triple the size. So you can use it as an indication, but actual size mostly comes to do the way the rough diamond is cut by professional diamond cutters. In fact, 1 carat is exactly 100 grams. And 2 carats is 200 grams. Carat is a very important part of calculating prices, mostly related to the rarity of a specific diamond. Most diamonds found today are around 1 carat diamond, most diamonds sold for jewelry are between 1 and 2 carats. Diamonds larger than this is incredibly rare to find and so the prices go up. This is especially true for colored diamonds, where a 2 carat colored diamond is potentially on par with a 10+ carat colorless diamond – all depending on the other three Cs of course. Also, prices don’t increase in proportion to carat size – a 3 carat diamond is not three times the price of a 1 carat. The price per carat is the one fundamental of diamond cost.

● Color, Factor 2

Most diamonds found and bought are categorized as colorless diamonds. These are the typical see-through sparkling diamonds most people around you will most likely have. When grading the color quality in colorless diamonds, we actually look at the absence of color. The less color a colorless diamond has, the rarer and more valuable it is, the higher prices are. If a colorless diamond has some color to it, this means it has a slight hue of yellow in it. This yellow hue might be only noticeable in a neutral and white light environment, or obviously noticeable in normal viewing conditions. Diamond color grading is done on a spectrum that ranges from D to Z, where D is absolutely colorless and Z has definite yellow hue. As you can see in the diamond color grading spectrum below, the various diamond color grades are grouped together because they will appear similar to the untrained and common diamond jewelry wearers.

The grouping of these color grades is not reflected in how the price increases. It is merely a way to group diamond colors in a way that makes sense for you as the consumer. Generally speaking, most people will buy diamonds in the G to I group, if they are not so much concerned with the internal quality of the diamond. This is mostly related to the diamond values in this category. For the most part, you won’t really see the yellow hue at all in G to I diamonds. Especially when you wear the diamond ring outside and the natural world around you is reflected in the diamond, a little yellow hue simply blends in and melts away. But if you are concerned with having an absolutely perfect diamond, then you should go for D to F diamonds. If you are buying diamonds as an investment, then it is strongly advised you buy D color diamonds.

● Clarity, Factor 3

The last of the three main factors are diamond clarity. This includes both internal inclusions and external blemished on the diamond, anything from crystals, knots, clouds, feathers, milky spots or tiny specks present in the diamond. In the industry, we informally refer to these spots as the diamond’s birthmarks, and they are part of the formation process when nature creates diamonds. But some diamonds have much more inclusions than others, and a lucky few are even free of any type of inclusions or blemishes. Similar to diamond color, diamond clarity is graded on a spectrum that ranges from flawless to having slight inclusions:

Clarity plays a role because we value absolutely perfect diamonds much more, and they are also very rare to find. Then there is also the beauty aspect where some people don’t want to see any inclusions in their diamond. Together, this is how diamond clarity affects the cost. That’s why most people, in general, don’t go much lower than VS2, which strikes the right balance between looking perfect yet still at a good price. I1 to I3 diamonds are not really used in diamond jewelry anymore, so you won’t come across those very often when buying diamonds. However, if you’re interested in buying diamonds as an investment, it is best to buy a Flawless diamond. Again, more on that later.

● Cut, Factor 4

While you won’t see diamond cut listed on the list, it does play a vital role in the value of the diamond. Diamond cut is the only one of the 4Cs that is directly influenced by hand. When a diamond is mined, we call it a rough diamond. Its shape is highly irregular. Diamond cutters then analyze the diamond with state-of-the-art equipment to see how they should cut the diamond to maximize yield and perfection. This is when the pavilion depth, for instance, is created. The cut diamond is then further polished to make the faceting of the diamond perfectly aligned and symmetrical. Altogether, this process is what makes the diamond sparkle so brightly. The cut determines how the light that enters a diamond is reflected outwards. There are standard names for the quality of the diamond cut: symmetry, polish, and cut are graded separately as poor, good or excellent. Ideally, you should always go for excellent on all three, or “Triple X” as we call it. This last part, how bright the diamond makes a final contribution to the final market value.
If you take all these 4 diamond characteristics into account, you can calculate what it really cost.

The steps to calculating diamond prices

All diamonds are categorized according to the carat weight, and each weight class has its own price list. Diamond is then further divided into either round shape or fancy shape (any other shape than round). But regardless of whether the diamond you want to buy is round shape or fancy shape, the way to calculate the list will be the same.

Price per carat

Say you are interested in a 3 carat diamond, G color with VS1 clarity grading. Then you need to look up the price list for 3 carat diamonds, and find the value that matches G color with VS1 clarity. In the list at the top of this page, we can see that value is 28,270 per carat. The Price per Carat value is very important to understand because it is not the final price yet. Why we keep saying we need to calculate the final price, is because there is a little math involved when working with Price per Carat. But luckily, it’s simple math only:

Diamond Value Calculator

Total Cost of Diamond = carat weight X Price per Carat

So in our example from above, we need to multiply 28,270 by 3, which brings us to a total of $84,810 for the 3 carat, G color VS1 clarity diamond. Say you want a specific carat weight, maybe to celebrate your anniversary date or something special like it, so you’re looking for a 3.12 carat, G color VS1 diamond specifically. Simple:
28,270 x 3.12 = $88,202 for the unique 3.12 carat diamond. Perfect for your anniversary on December 3rd, or March 12th of course.

What about other diamond shapes? And colored diamonds?

For all other diamond shapes, or fancy shape diamonds, you apply the same method as we did here to find diamond values, but then for the specific list for fancy shape diamonds. Remember that when you are looking for a different carat weight class, you need to find the appropriate list for that carat weight, and multiply the Price per Carat value accordingly. Colored diamonds are far more difficult to assess, both in terms of quality and cost. There are no standardized lists for color diamond. You need to get in touch with diamond advisers if you are looking for a colored diamond and want to see what the current diamond prices are for available diamonds today.

● Where to find diamond prices aka diamond price lists

We’ve said a couple of times that you need to find the diamond price list for the diamond price per carat you are looking for. But where do you find the list? Luckily, you are already on the world’s most extensive diamond information platform. The Diamond Registry is the number one source online for loose diamonds at wholesale prices, and we publish and update our diamond price charts regularly so that you can see today’s wholesale diamond prices. Our list page shows you the list for all carat sizes below 10, both for round shapes and fancy shapes.

In fact, Diamond Registry was the first online source of diamond price information, publishing wholesale diamond prices on a regular basis online since 1996. Before that, we were the first to publish a list of every diamond price and diamond price chart in our newsletter bulletin back in 1961. Many subscribers in those days were from the diamond industry themselves and relied on the Diamond Registry as the primary accurate source of price information. Since then, we have grown into a fully-fledged diamond information and education platform that closes the gap between the public and the diamond industry, by publishing the accurate wholesale diamond prices worldwide and educating the diamond buying public.

● What does it mean to buy loose diamonds at wholesale prices?

What we have discussed here, all refers to loose diamonds in the wholesale diamond industry. Diamond Registry is the main entrance to the wholesale diamond industry for the diamond buying public, and wholesale prices are far lower than retail prices.
Retail diamond jewelry has a lot of additional costs factored into the final price, which makes it a lot more expensive than wholesale diamonds. When you buy jewelry from the diamond shops, you pay for the advertising and marketing costs, the overhead costs of running a shop in that prime location, and quite often just for the brand name. You can avoid these costs easily buying through the Diamond Registry wholesale diamond platform.

● Buying diamonds as an investment: what is the best diamond price?

Mounted onto jewelry or not, diamonds, if bought correctly, can also be bought as promising investments. Many diamonds have broken record after record during diamond auctions, most notably at Sotheby’s and Christie’s auctions. Plus, different than a stock portfolio, you can also enjoy your diamond investment and wear it for elegant occasions and events. An investment you can enjoy actively, while you wait for the value to increase.
If you want to buy diamonds as an investment specifically, you should talk to a diamond adviser to help you buy the best diamond. But to give you an idea, there are a number of things you need to consider when buying diamonds as an investment.

• Don’t start with prices

Don’t start looking for a diamond to buy for investment purposes looking at the price. It’s good to have a budget already in mind, but it’s not the starting point when looking for a diamond to invest in. That way you might buy a diamond that could be beautiful for a good price, but not necessarily a smart investment.

• Start with color and clarity

This is an easy rule. If your purchase is purely investment driven, only buy D color and Flawless clarity. The absolute best, most perfect diamonds are the ones that increase in price the most over time. Not only that but selling it will be much easier as the demand is very high for perfect diamonds.

• Now look at carat weight, for diamond prices

Look at the different carat weights, and calculate the full price for the perfect diamonds in each class. This is how you determine what carat weight diamond falls within your budget for your diamond investment.

• Then get in touch with a diamond adviser

There are many more aspects involved when it comes to buying diamonds purely as an investment. The above information is just a simplification of the basics. You should always get in touch with a diamond adviser to help you make the best purchase for your investment.

● Diamond certificates – certainty about quality

Whether you are buying diamonds as an investment, jewelry or as a gift for like an engagement ring, there’s another element which is just as important as diamond price: diamond grading certificates. Every loose diamond, and finished diamond jewelry comes with a grading certificate that shows you the exact graded quality features. These certificates reveal a number of different features including the 4Cs, fluorescence, symmetry, image of the diamond’s measurements and a diagram of any present inclusions or blemishes. The certificate has a report number, which is laser engraved on the girdle of the loose diamond – barely visible at 10x magnification. That number ties the diamond to the certificate, and all certificates have a hard copy which you get with your purchase, and a digital version to be found online through the database.

Which diamond grading certificate is the best?

There a number of different diamond grading certificates available to you, but the absolute best as agreed upon by the diamond industry are GIA certificates. The GIA diamond grading lab is the most reliable and accurate when it comes to diamond grading, so the prices you see are what they should be regarding the quality of the diamond. In fact, the 4Cs was developed by the GIA to grade loose diamonds more systematically and their standards and methods for diamond grading have been copied by the other grading labs. So the GIA is the original source of grading and the most authoritative when it comes to assessing the quality of loose diamonds and therefore making it easier for the industry to calculate the accurate diamond price.
