This is a 4.10 carat round diamond graded by GIA as Fancy No Overtone Black with no reported treatments.

Black diamonds are polycrystalline with numerous inclusions that cause their dark coloration, which differs fundamentally from colorless diamonds. The GIA certification provides documentation of the carat weight, color grade, and lack of enhancement.
