The color of a diamond refers to the relative amount of yellow, brown or gray body color that a stone possesses. The G.I.A. scale starts at "D" and goes through "Z", with "D" being void of any body color, and "Z" having a light yellow, brown or gray color.

(With actual stones, the color difference would appear like this:)

The color of a diamond depends on the quantity and nature of trace elements within the stone and how these elements originated. Most commercially available diamonds range in color from colorless to pale yellowish. There are other colors of diamonds known as "fancy diamonds" which can be pink, blue, green, yellow, brown and even black.
