Diamonds are graded for color face down, against a white background. The diamond is then assigned a letter grade. Most diamonds used for jewellery purposes fall into the Near Colorless Category – G to J. 미국보석연구소 (G.I.A.) grades color alphabetically from D (totally colorless) Z야 (노란색).

If you plan on mounting the stone on a platinum or white gold setting, consider a diamond in the D-G range. Yellow gold will be much more forgiving to a less than colorless stone, but regardless of the setting, the diamond will start to appear yellow if the color grade is lower than about J.
