What Is Diamond Color?

Color describes the natural tint found in white diamonds. Most white diamonds have a slight yellow hue. The closer a diamond is to being completely colorless, the rarer it is. Color is graded by comparing each stone to a master set, with letter grades from “D” (colorless) to “Z” (light yellow). Diamonds outside the D–Z range are extremely rare and classified as fancy color diamonds, valued for their vivid and vibrant tones.

Does Diamond Color Matter?

A diamond’s color has a direct impact on its appearance. Stones with lower color grades may show a slight yellow tint rather than the desired bright white. Additionally, the Orrling Gemological Laboratory does not accept diamonds with strong or excessive fluorescence, which can make a stone appear milky in natural light.

The Orrling Difference

Orrling's Color Standards

At Orrling, our laboratory experts determine each diamond’s color by comparing it to authenticated “master” stones. Every diamond is then graded on a precise scale. Orrling only selects diamonds in the “colorless” to “near colorless” range, with those closest to “colorless” being the rarest and most valuable.
