What To Look For

0.49-ct Blue Diamond
The most prized hues are red, pinks, blues, and greens.

Compared to fancy yellows and browns, diamonds with a noticeable hint of any other hue are considerably more rare. Grading fancy color diamonds is complex and specialized, and it takes highly trained laboratory graders to complete the process accurately.

Fancy Color Diamond Clarity

Color is the dominant value factor. Even diamonds with numerous inclusions that result in a low clarity grade are prized by connoisseurs if they display attractive face-up color. Of course, inclusions that threaten the gem’s durability can lower a fancy-colored diamond’s value significantly.

Round Brilliant Fancy Color Diamond
Fancy shapes can boost the intensity of color.

Cutters discovered that certain styles—typically mixed cuts like the radiant—can intensify yellow color in diamonds that are toward the lower end of the D-to-Z color-grading scale. When carefully fashioned as radiant cuts, many yellow-tinted stones can become fancy yellows when viewed face up.

Rare Reddish-pink Diamond
Even sizes under a carat are very valuable.

As with diamonds in the normal D-to-Z color range, large fancy color diamonds are rarer and more valuable than small ones.
