  1. “The Diamond Color Chart starts with the letter D. (There is no A, B or C)”

    But to clarify, the reason there is no A, B, or C for diamonds is because those letters are used to grade the quality of colored gemstones, like Rubies, Sapphires, Emeralds, Amethysts and so forth.
    They just didn’t choose to throw out the A, B and C because they didn’t like them! ;-)

    • I was always lead to believe that A,B,C, was left out because it was confusing, inconsistent and inaccurate with older grading systems that were in place before the Industry Standards were brought about by GIA in the 40’s and 50’s. Didn’t know it had dealt specifically with “Colored Gemstones”, just Diamonds in particular. Good to know! :)
