1.68 Carat Natural Black Round Diamond GIA

This is a 1.68 carat round diamond graded Fancy No Overtone Black by the Gemological Institute of America. The stone is untreated and offered as a loose stone. Black diamonds of this size and grade are relatively uncommon in the market, as the coloration typically results from graphite inclusions or structural defects within the crystal lattice. The GIA certification provides documented confirmation of the carat weight, color grade, and treatment status.
