A natural fancy color diamond is priced on the strength and rarity of its color first, and its size and clarity second. That is why two yellow diamonds of the same carat weight can be thousands of dollars apart, and why a pink or blue can cost many times more than either.
Colored diamond pricing is harder to research than colorless diamond pricing. There is no public price chart, few online retailers carry rare colors, and auction headlines in the millions make everyday stones hard to judge.
This guide explains how natural colored diamonds are valued, how KK Diamonds sets its prices, what my services cost, and the questions buyers ask most often. I have worked in the diamond trade since 2011 and deal only in natural, untreated diamonds.
How are fancy color diamonds priced?
Color drives the price of a fancy color diamond more than any other factor. With colorless diamonds, buyers weigh the 4Cs fairly evenly. With colored diamonds, the color itself is most of the story.
These are the factors I look at, roughly in order of how much they move the price:
- Hue. The base color sets the starting point. Reds, blues, pinks and greens are far rarer than yellows and browns, so they start from a much higher price.
- Intensity. GIA grades color strength on a scale running from Faint through Fancy Light, Fancy, Fancy Intense and Fancy Vivid, with Fancy Deep and Fancy Dark for darker stones. Each step up in intensity can change the price dramatically.
- Secondary colors. A pure color is worth more than one with a modifier. A “Fancy Pink” is generally valued above a “Fancy Brownish Pink” of the same size.
- Color distribution. Even color across the stone is worth more than color that is patchy or concentrated in one area.
- Carat weight. Larger colored diamonds are much rarer, so the price per carat usually rises with size, not just the total price.
- Clarity and cut. These matter less than with colorless diamonds. A cut that deepens the color face-up can add more value than a higher clarity grade.
- Natural origin and documentation. A GIA Colored Diamond Grading Report confirms that the color is natural rather than treated or lab-grown. Treated and lab-grown colored diamonds sell for a fraction of the price of natural ones.
The result is that two stones described the same way in a sentence, such as “a 1-carat yellow diamond,” can sit at very different prices once intensity, purity of color and documentation are considered.
Why is there no price chart for colored diamonds?
Colored diamonds are too individual to price from a chart. The trade prices colorless diamonds from the Rapaport list, which sets benchmarks by shape, weight, color and clarity. No equivalent list exists for fancy colors, because two stones with the same grade can still look noticeably different.
The closest public reference is the Fancy Color Research Foundation’s index, built from wholesale transactions since 2005. It tracks price movement over time rather than publishing actual prices. Since 2005 the index has risen about 202%, and over the past year prices have been essentially flat, down 0.5%.
In practice, a colored diamond is valued the way fine art is: against recent sales of comparable stones, adjusted for its particular color, size and documentation. That is why an experienced eye matters more here than any online calculator.
How KK Diamonds sets its prices
I price each stone once, fairly, and I don’t play the markdown game. You won’t see inflated tags followed by “sales,” because a price that can drop 30% overnight was never a real price.
Here is what goes into a KK Diamonds price:
- The stone’s own characteristics. Hue, intensity, distribution, size and documentation, judged stone by stone rather than by formula.
- Current market evidence. Recent wholesale and auction results for comparable natural colored diamonds.
- The cost of doing it properly. Grading reports, insured shipping and the time spent sourcing the right stone.
Because I work privately and by appointment, I don’t carry the overhead of a retail storefront. That lets me focus spending on the stones themselves rather than on showrooms.
When a client wants more value, I prefer to add it rather than cut the price. That can mean design work, documentation or service included with the piece, so every client pays the same fair price for the same stone.

Shipping, returns and trade-ups
Every shipment is fully insured, and the terms below are the same for every client.
- Insured shipping. Packages are insured up to $150,000 per FedEx box. Anything above that value travels by Malca-Amit, a specialist secure carrier.
- Ship dates. In-stock pieces ship within 72 hours, Monday to Thursday only, so nothing sits in transit over a weekend when insurance doesn’t cover delivery.
- International orders. I don’t ship to countries experiencing war or severe economic instability.
- Returns. Returns carry a 20% restocking fee, which covers labor costs I can’t recover.
- Lifetime trade-up. Select colorless diamonds qualify for a lifetime trade-up. The new stone must be worth more than your trade-in credit, so the program is a path to an upgrade rather than a refund.
Frequently asked questions about diamond prices
Are colored diamonds more expensive than colorless (often called white) diamonds?
It depends on the color and its strength. Fancy Vivid yellows and almost all natural pinks, blues and reds cost more than colorless diamonds of the same size. Lighter yellows and browns can cost less than a fine colorless diamond. Colorless diamonds are often called white, though true white is itself a rare fancy color.
What is the most expensive diamond color?
Red is the rarest, followed by blue and pink. In 2015 the Blue Moon, a 12.03-carat Fancy Vivid Blue, sold at Sotheby’s Geneva for about $4 million per carat.
Why are natural colored diamonds so expensive?
They are extremely rare. Natural fancy color diamonds make up roughly 0.01% of all diamonds mined, and strong, pure colors in larger sizes are rarer still.
Which colored diamond is the most affordable?
Yellow is the most accessible fancy color, along with champagne and cognac browns. They offer real color and natural rarity at a fraction of the price of pink or blue.
Do colored diamonds hold their value?
Natural colored diamonds have held up well over the long term. The Fancy Color Research Foundation’s index has risen about 202% since 2005, though prices have been flat over the past year. No diamond should be bought purely as an investment, and resale prices are generally below retail.
How do I know a colored diamond is natural?
Ask for a GIA Colored Diamond Grading Report. It states whether the color is natural, treated or lab-grown, along with the color grade. Every diamond I sell is natural and untreated.
Are lab-grown colored diamonds cheaper?
Yes, much cheaper, and their prices keep falling. They are a different product from natural colored diamonds, which is why I deal only in natural stones.
Can I negotiate on price?
I don’t inflate prices to leave room for haggling, and I don’t run sales. If budget is a concern, tell me early. I can suggest a different size, intensity or color that gets you more for your money.
