1.59 Carat Natural Black Round Diamond GIA

This 1.59 carat diamond is a round brilliant cut with a Fancy No Overtone Black color grade from GIA. The stone is untreated natural diamond and is sold as a loose stone. Black diamonds of this size and color saturation are relatively uncommon in the market, as most black diamonds contain graphite or other inclusions that create their dark appearance. GIA certification provides independent verification of the stone's characteristics and carat weight.
