1.78 Carat Natural Black Round Diamond GIA

This 1.78 carat diamond is a natural, untreated round brilliant with a Fancy No Overtone Black color grade from the Gemological Institute of America. The stone is offered loose, allowing flexibility for custom setting. Black diamonds of this size and color saturation are relatively uncommon in the market, as most fancy black diamonds are treated or irradiated to achieve their dark appearance. GIA certification documents the stone's natural origin and color classification.
