- 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 Jewelercart.com, 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.
