The color of a diamond can vary from completely white (D) to yellow or brown (Z).

Pink, bluish stones can be found. However, gems that are absolutely flawless and without any defects are most valued.

There are also colored diamonds, so called "fancy color", but M/Z category diamonds are not "fancy color" diamonds, because their color is too dull. The color is graded using the letters of the alphabet from D to Z.

H – WHITE 

I/J – SLIGHTLY TINTED WHITE
