About Diamond Color
Most diamonds, although appearing colorless, actually have slight tones
of yellow or brown. As the tones become more apparent, the rarity and
the cost decrease.

But Why Start With "D"?
Before GIA universalized the D-to-Z Color Grading Scale, a variety of other
systems were used loosely, from A, B, and C (used without clear definition),
to Arabic (0, 1, 2, 3) and Roman (I, II, III) numbers, to descriptive terms
like "gem blue" or "blue white," which are notorious for misinterpretation.
So the creators of the GIA Color Scale wanted to start fresh, without any
association with earlier systems. Thus the GIA scale starts at the letter D.
Very few people still cling to other grading systems, and no other system has
the clarity and universal acceptance of the GIA scale.
The 4 C's of Diamonds are Cut, Color, Clarity and Carat Weight.
