3.58 Carat Natural Black Round Diamond GIA

This 3.58 carat diamond is a round brilliant cut with Fancy No Overtone Black color grading from the Gemological Institute of America. The stone is untreated and offered as a loose diamond. Black diamonds of this carat weight and size are relatively uncommon in the market, as the color results from high concentrations of graphite and structural defects rather than trace elements found in colored diamonds.
