Color
The "color" of a diamond refers to the presence or absence of inherent coloration in a white diamond. The whiter the diamond is the greater its value since a colorless diamond will allow increased light to pass through it and will consequently emit a greater amount of fire and brilliance. An appropriate analogy would be the difference between a clear glass window's superiority in allowing light to pass through it, versus a (color) stained glass window. Diamonds are graded for color against a white background so as to eliminate the possibility for any outside light to be absorbed by the diamond.
In the diamond industry we refer to the GIA color grading scale which begins with the letter "D" indicating the highest rating for a colorless diamond, and makes its way down the alphabet as it grades stones with hues of faint or significant yellowish and brownish coloration. The scale continues all the way to the letter Z.
