GIGJ Colour Grade Chart

Color refers to a diamond's lack of color, grading the whiteness of a diamond.

A color grade of D is the highest possible, while Z is the lowest.

A diamond's color grade is based on its lack of color. The less color a diamond has, the higher its color grade. After cut, color is generally considered the second most important characteristic when selecting a diamond. This is because the human eye tends to detect a diamond's sparkle first, and color second. Diamonds graded J or better are colorless or near-colorless.
