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.
