Diamond Color Chart

Diamond Color

Color grades, using the GIA scale, ranges from D to Z, with D being colorless and Z being heavily (usually yellow) colored. Colorless stones (designated D, E, or F) command the highest prices. Diamond colors rank in the following groups:

Colorless: D, E, or F
Near Colorless: G, H, I, or J
Faint Yellow Tint*: K, L, or M
Very Light Yellow Tint*: N, O, P, Q, or R
Tinted Light Yellow*: S, T, U, V, W, X, Y, or Z

* The tint viewed may actually be yellowish, brownish, or gray.
When grading diamonds, a nonreflective white background should be used. Diamond graders have to be careful about the surrounding environment. Clothing color, lighting, and the color of their instruments may affect the outcome.

Fancy Colored Diamonds


Diamonds of certain colors are called fancies. These colored diamonds have intense natural colors that in some cases are very rare and command exceptional values. These stones are not color graded using the scale above. Brown and yellow diamonds are the most common members of the fancy diamond group and have a distinct beauty of their own. Naturally red, blue, purple, and green diamonds are extremely rare and highly sought after by designers and collectors.

Diamond Buying Tip: Color is one of the most noticeable characteristics of a diamond. Most people can notice whether or not a diamond is colorless (the most desired). The setting of the diamond can affect the appearance of color. If the diamond is colorless, a white gold or platinum setting will enhance the diamond's whiteness. But if the diamond has a yellowish tint, a yellow gold setting may help mask the yellow tint, making the diamond appear whiter.
