Diamond Prices Chart
Shoppers often wonder how and why two identical diamonds have a significant difference in price.
Because diamonds are among the most valuable gemstones in the world, learning how their prices are determined, who determines them, and why two identical diamonds might not have the same price tag is critically important. Having answers to these questions will set a pro apart from most buyers.
Without essential price information and technical insights, a diamond buyer will likely make a misinformed decision. As such, the price charts below aims to help buyers determine the approximate price of a diamond in a given range.
In this guide, we also highlight and discuss the key factors that influence the final price of a diamond. In addition to the 4Cs, we share our insights on the importance of diamond certification, the physical appearance of a diamond, and buying diamonds online versus locally.

Note: avoid fluorescence in high color grades and prioritize cut.
Full Diamond Prices Charts
Even though a single pricing formula cannot be applied to all diamonds, the charts below illustrates our best approximate diamond prices. Because diamonds are natural gemstones with unique characteristics, each stone should be evaluated based on its own quality.
The indexes below are for diamonds in the one to three carat range. It reflects average prices for GIA and AGS graded round diamonds based on carat weight, clarity, color, cut, and none-to-faint blue fluorescence. We have also provided estimates for other "fancy" cut diamonds in the subsequent section.

Fancy Cut Diamonds Prices
Round cut diamonds are more expensive than fancy cut diamonds. It takes a larger rough diamond to cut a round diamond than it does for a fancy diamond. The estimates below show the difference between the prices of round diamonds in the above charts and fancy cut diamonds. The demand and supply of each diamond shape and surplus inventory in global circulation also influence these prices.
- Oval cut diamonds: priced 5-15% lower than round diamonds.
- Princess cut diamonds: priced 17-26% lower than round diamonds.
- Cushion cut diamonds: priced 22-30% lower than round diamonds.
- Radiant cut diamonds: priced 20-27% lower than round diamonds.
- Emerald cut diamonds: priced 19-27% lower than round diamonds.
- Pear cut diamonds: priced 15-22% lower than round diamonds.
- Marquise cut diamonds: priced 23-32% lower than round diamonds.
- Asscher cut diamonds: priced 21-31% lower than round diamonds.
Rough Diamonds Prices
The market for uncut rough diamonds is highly distinguishable from polished and cut diamonds.
Mainly, De Beers (the diamond giant), ALROSA, and Rio Tinto, among others, maintain stable prices by regulating the volume of available rough stones in the market at a specific time. This controlled supply stabilizes and determines the prices of polished diamonds.
It is important to note that unless a supplier fully complies with the Kimberly process, they are not permitted to be involved in the business of rough diamonds.
De Beers does not control the rough diamond market in its entirety. However, the company significantly influences the prices of rough diamonds. While, initially they supplied about 85% of all rough diamonds to the market, their market share has dropped to about 25-35%.
De Beers Sight holders are large diamond dealers who cut and supply diamonds to the market. De Beers organizes ten sights annually, during which they present several collections of rough diamonds to sight holders; each package could be worth anywhere between $1-25 million dollars. Being a De Beers sight holder is very prestigious in the diamond trade.
Polished Diamonds Prices
When polished diamonds are priced, they are classified into two categories: diamonds priced against Rapaport’s Price List and those that are not priced against the said list.
The Rapaport Diamond Report of Polished Diamonds
When polished diamonds are priced, they are classified into two categories: those priced against Rapaport’s Price List and those not priced against it.
The Rapaport Diamond Report of Polished Diamonds
The pricing of polished diamonds is based on a standard process within the industry. Several factors influence the pricing equation, having to do less with cost and more with market demand.
Martin Rapaport, a Belgian industry broker, and his team calculate the prices of diamonds. These prices mirror the present market state and are published weekly on the Rapaport Diamond Report for premium subscribers.
In the report, the primary factors determining the cost of polished diamonds are three of the 4Cs - carat, color, and clarity.
The Rapaport Report displays a price for a combination of diamond color and clarity, with a weight range of 0.01 to 5.99. Rap prices are usually high and typically used by traders for reference. Only some sellers strictly follow the prices in the Rap Report.
How to use the RapNet Price List
RapNet is a jewelry trading network powered by Rapaport. Being the world’s largest, the network is selectively available to premium members of the diamond and jewelry trade and is the most trusted in the industry.
On RapNet, buyers and sellers directly interact without trading fees or commission charges. Members of the RapNet network have access to over 1,000,000 diamonds of any shape, clarity, size, and color. For a $699 annual membership, it offers an effective platform to source and sells diamonds.
The RapNet Asking Price List
The RapNet Price List presents the average and best-asking prices on the RapNet Diamond Trading Network for certain diamond classes available for sale worldwide. The RapNet Asking Price List prices are limited to diamonds with a very good cut or above-cut quality, Rapaport specification-2, and graded by GIA.
The RapNet asking price provides a listing for sale for a specific date. The list presents discounts below or above the standard Rapaport Price List.
How does the RapNet Asking Price List differ from the Rapaport Pricing List?
Typically, the Rapaport Price List presents the High Cash Asking Price that the global diamond trade uses to find the base value to approximate the prices of a broad range of diamond sizes and qualities. On the flip side, the RapNet Asking Price List is the actual price sellers ask for specific diamonds.
Interestingly, the RapNet Asking Prices List reveals comprehensive data about discounts and premiums to the standard Rapaport Price List. Also, the RapNet Asking Price List includes different diamond shapes, whereas the Rapaport Pricing List offers prices for round diamonds only.
How to use the RapNet Asking Price List?
To read and calculate the diamond price using the RapNet Asking Price List, it is essential to be familiar with the chart below.
Example of RapNet Price List
The table above is the RapNet Asking Price List, which is only accessible to jewelers and dealers.
The diamond carat size range is at the top of the list, followed by publication dates. Next to them is the price for each diamond and the discounts available; the prices are consistently in the hundreds.
For instance, the $12,100 represents the best RapNet asking price offer for a round, D, IF 0.9-0.99 diamond.
It is important to remember that there is a big difference between the Rapaport Price List and the RapNet Asking Price List.
Discount and Premium Prices
The real work in calculating diamond pricing is judging the discount or premium to the Rap price. Often, diamond deals are made at a discount of the Rap price. Two diamond dealers will haggle at the Rap discount point.
However, note that the three Cs of diamond quality on Rap price only bring us the baseline; from then onwards, things turn subjective. Factors like cut, fluorescence, and inclusion quality are considered so that the discount Rap price can be determined.
The “20 Below,” or “20 Back,” Rule
To understand this correctly, consider a diamond with an excellent cut, a clarity grade of SI1, and the color H containing no fluorescence. This diamond will look precisely like a G and might trade at -20% or even -15% less than the Rap price for a similar G grade diamond. In the diamond world, such a scenario is known as “20 below” or “20 back.”
A dealer will want to bargain for such a diamond at “15 back,” but a diamond buyer will desire to gain it at “20 below.” To calculate the actual price, a buyer must subtract the “percentage back” from the Rap Price.
Sweet Spots of Value
When inspecting the Rapaport Price List, buyers will see how different prices between adjacent prices in each matrix unfold; they are not uniform.
For instance, the price difference between a 1 carat diamond of VS2 clarity and color H and a 1 carat VS2 clarity and color G is $1,000. But the price difference between a 1 carat G VS2 and a 1 carat G VS2 is only $500.
In this industry, prices are rarely based on sound reasoning; the pricing process becomes emotional.
To help get through these inconsistencies, a buyer should seek an expert diamond dealer’s assistance to take advantage of the sweet spots within the pricing grid. Such support is critical because it will help determine if upgrading from H color VS2 clarity to G color VS2 clarity is worth the price difference.
The Effect of Rap Prices
Rap prices help regulate diamond price manipulation, which is good news for diamond buyers. Before Rapaport standardized diamond prices, dealers within the industry used different methods to determine the value of a diamond without any consistency.
In the first decades of introducing Rap Prices, some dealers continued selling diamonds above the list price. However, with growing popularity, most retailers are taking Rap prices seriously.
Limitations of the Rapaport Price
- It only focuses on color, clarity, and carat as graded by GIA and assumes that the cut is of an excellent grade.
- Rapaport also does not include polish and symmetry.
- Different diamonds of the same grade can have different outlooks.
It is worth noting here that a diamond with a brighter appearance sells at a higher price. One F-colored diamond can appear brilliant, while another of the same color might be less so because of strong fluorescence. While one S12 diamond might be perfectly eye-cleaned, the one next to it might have noticeable flaws.
The Rapaport List Price is High.
Rapaport itself states that the list assumes the highest asking price, taking advantage of this most retailers apply discounts on the Rap prices. Some diamond dealers share the Rapaport sheet with customers to convince them that they are getting a fair deal since the dealer has priced the diamond below the listed price.
A Deeper Dive into Calculating Diamond Prices
In order for buyers to get the best value for their money, below we will highlight key factors that influence the price of a diamond.
All diamond buyers will hear about the 4Cs at some point, including carat, cut, color, and clarity. However, what they will not know is that there are subdivisions, judgment calls, and variations that diamond dealers do not discuss often. Even the Rapaport diamond report does not list these details with its pricing data.
The 4Cs dictate how much a diamond will cost. The more colorless and flawless a diamond is, the more valuable it gets.
Tip: Save money on color and clarity as these factors are usually unnoticeable and unobservable to the naked eye. Most shoppers look for a diamond that is just eye-clean and colorless.
Carat has a significant impact on the price of a diamond. For instance, consider several diamonds with similar color, clarity, and excellent cut. The price of a diamond directly increases with carat weight. Theoretically, a 0.5 carat diamond will cost double what a 0.4 carat diamond costs—the case is similar for 0.75 and 1 carat diamonds. Big diamonds are scarce; their prices will reflect that.
However, looking closely, buyers will notice that the most rapid price shift happens at half carat and whole carat points. Searching for a diamond just slightly under a whole number, e.g., 0.9 instead of 1.0 carat, could be an excellent option for someone with budget constraints.
How to calculate the price per carat?
The per carat price increases as weight and quality increase. For instance, if one carat costs $2500, a 0.5 carat diamond would cost $1250. A buyer would calculate the price of that carat by multiplying 2500 X 0.5.
However, buyers also need to consider the remaining 3Cs of a diamond—color, clarity and cut. Also, it is noteworthy that different shapes come at different prices.
Buyers must compare diamonds with the same grading report or "certificate", clarity, fluorescence, cut, and color. Besides, it is also essential to inspect the physical appearance of a diamond to determine tints, external flaws, and haziness.
It important to note that diamond buying is often driven more by emotions than reason. For example, a 0.99 carat diamond costs 1% more than a 0.98 carat diamond. But a 1.00ct diamond costs 10-20% more than a similar 0.99ct diamond simply because the prior can be called a full carat weight diamond.
Since diamond prices jump rapidly as the carats increase, most diamond cutters are compelled to cut a gem that strikes a whole number. Unfortunately, stressing hitting a total carat instead of maximum brilliance results in undesirable cut.
The cut of a diamond is the most critical C to prioritize.
A diamond’s cut defines scintillation, fire, sparkle, and overall brilliance. An ideal cut can create a flash that hides inclusions and masks undesirable colors, making an average diamond look like a top-quality grade.
It important to not confuse a diamond’s cut with a diamond’s shape. For example, round is a shape, not a cut. The cut is the symmetry, proportion, and polish, whereas a diamond’s shape the external form of a diamond.
The cut of a diamond determines how brilliant a diamond is and defines the angles/how light travels through each facet. Poorly cut diamonds leak light, resulting in a dull diamond.
An ideal cut diamond has seamless proportions, perfect symmetry, and excellent polish. Facets and dimensions are purposefully cut to maximize the reflection of inner light.
Aesthetically, the cut significantly affects a diamond’s beauty—the better the cut, the more brilliant the diamond. Because cut is a higher priority in a diamond, it is recommended that buyers get the best cut possible. Downgrading the other Cs for an ideal cut is completely acceptable.
An ideal cut can also make a diamond appear large, whereas a poor deep cut can increase the carat weight.
Please check our article on ideal vs excellent cut proportions for reference.
Color also has a significant influence on the overall brilliance of a diamond. It ranges from D (colorless) to Z (yellow/brown tint). However, most retailers do not sell diamonds higher than K color.
Colorless diamonds are exponentially rare and thus come at a premium price. Most diamonds have a slight yellow hue that the naked eye cannot detect, and even though the price difference from one color to the next is random, here is something buyers need to think through:
It is difficult to tell a colorless diamond from an almost colorless one, implying that there is no point in spending extravagantly on something with no visible difference.
To get the best value for the money, consider going with color G, typically viewed as the inflection point between a slightly noticeable hue in a diamond and a colorless diamond. Most people can hardly differentiate between the two.
G is a sure bet, but it is still okay to have a diamond with a H or I color and an excellent cut rather than a fair cut grade diamond with an F color.
The clarity of a diamond describes the inclusions/flaws in a diamond. Flaws usually comprise two types:
- Inclusions (internal flaws)
- Blemishes (flaws on the surface)
Most diamonds have flaws, but what matters the most is the visibility and location of the imperfections.
Diamond clarity is graded based on visible flaws under an X10 magnification.
A clarity of VS2 can be the best value. For instance, while looking at price differences between different clarity grades with the same carat, cut, and color diamond, buyers will notice that internally flawless and VVS diamonds are priced higher because they are rare. However, just as with color, it is nearly impossible to appreciate high clarity grade because the difference is not visible to the naked eye.
Remember that diamonds with identical 4Cs (including clarity) can differ significantly in pricing; this is so because of the type of flaw and its visibility or lack thereof. For example, there are SI2 diamonds that are perfectly eye-clean, while others have unappealing large black crystals or clouds in them.
Beyond the 4Cs, additional factors that influence the price of a diamond include certification, physical appearance, and the shape of a diamond.
Certification is essential, so much so that it is often assumed as the 5th C.
Many diamond grading labs operate globally, including GIA, AGS, IGI, and HRD, among others. Each one of them has its grading criteria and standard.
A grading report from a reputable lab is arguably the most critical factor in determining the price of a diamond. It will inform a buyer that the diamond is a natural gemstone and properly graded.
With a grading report, a buyer can also confirm the stone's quality from an unbiased third party.
GIA and AGS stand out as they have a global reputation for having the highest and most consistent grading system. For instance, GIA might grade a diamond as SI2, but a different lab would grade it as VS2 clarity. Some grading labs may even inflate their grading by as much as 2 whole grades.
Finding a grading report or certificate for a diamond with an I1 clarity grade is rare. Well-established companies rarely sell a GIA certified I1 diamond and assume that they might sell such diamonds at the same or higher prices without a certificate.
While diamonds graded by GIA and AGS might appear more expensive, the reality is that they are more consistent and have provided accurate grading.
While a grading report can confirm the quality of a diamond, it cannot confirm how exactly a stone appears in person. Because two diamonds with the same grades can appear different in person, the visual appearance of a diamond also influences its price.
Depending on the shape, the per carat price of a diamond increases because it takes a bigger rough diamond to cut into some shapes than others. Popularity of the shape is also important.
Round diamonds are the most expensive. Their popularity stems from the fact that they display incredible brilliance.
Princess cut diamonds are the next most popular shape and expensive because they sparkle the most after a round diamond.
An oval diamond is a modern diamond shape with an elegant twist. Oval cuts are very popular and are good alternatives to round cut diamonds.
Other cuts like Pear, Asscher, Emerald, and Marquise are fancy cuts and cost less than the round diamond shape.
Choosing a shape other than round can help buyers save as much as 20%-30%.
Diamond fluorescence is a soft glow—usually blue—that a diamond emits under ultraviolet light. This visual effect is natural in 1/3 of all the diamonds in the world.
Often, the blue fluorescence does not negatively influence a diamond’s appearance. However, because fluorescence is a negative factor, it can help save money without compromising quality if considered in G-J colors. Blue fluorescence can counteract any yellowish hue that a lower-grade diamond may have. Therefore, it may improve the color appearance of diamonds with grade G or lower.
On the flip side, yellow or green fluorescence will invariably lower a diamond’s price unless the diamond is a fancy yellow or green. In such a case, this fluorescence color will make the diamond appear more saturated, thus enhancing its value.
Generally, fluorescence decreases the value of D-F color grade diamonds, though it may not affect the price of I-J diamonds. Medium to strong blue fluorescence can cause the stone to appear milky, thus decreasing its value.
