Color
The body color of a diamond in its purest form is colorless. A colorless diamond is very rare, as traces of yellow or brown are usually present. The color of a diamond is evaluated by the unaided eye using a 23 letter grade scale, starting a t D, the highest grade, and continuing through to Z, the lowest grade. The less color a diamond has, the more valuable it becomes.
While colorless gems are the most sought after, other diamonds with colors of red, pink, blue, green, and amber – often referred to as “fancies” -- are options as well.
