Key Points

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.
Blue Nile only sells diamonds with a color grade of J or higher.

Color manifests itself in a diamond as a pale yellow. This is why 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 (light performance) first, and color second.

At Blue Nile, you'll find only the finest diamonds with color graded D-J. Diamonds graded J or better are colorless or near-colorless, with color that is typically undetectable to the unaided eye.


Z-N	Noticeable color. Not carried by Blue Nile.
M-K	Noticeable color. Not carried by Blue Nile.
J-I	Near-colorless. An exceptional value with slightly detectable warmth or tone.
H-G	Near-colorless. Color difficult to detect unless compared side-by-side against diamonds of better grades. An excellent value.
F-E	Colorless. Minute traces of color can be detected by an expert gemologist. A rare diamond.
D	Absolutely colorless. The highest color grade. Extremely rare.

What Color is Right for Me?

For the purist, look for a colorless diamond with a grade of D-F for a diamond with no discernible color.
For an excellent value in a diamond with little or no noticeable color to the unaided eye, look for a near-colorless grade of G-I
