2.64 Carat Natural Black Lozenge Diamond GIA

This is a 2.64 carat diamond with a lozenge shape and Fancy No Overtone Black color grading from GIA. The stone is untreated and offered as a loose stone. Black diamonds of this size and color grade are relatively uncommon in the market, as most black diamonds result from high concentrations of graphite inclusions or surface-reaching fractures that obscure the crystal structure. GIA certification documents the stone's specifications and lack of treatment.
