0.64 Carat Natural Black Round Diamond GIA

This 0.64 carat diamond is a natural black diamond with Fancy No Overtone Black color, meaning it exhibits pure black coloration without secondary color casts. The stone is cut in a round shape and comes as a loose stone. It has been certified by the Gemological Institute of America (GIA) and shows no evidence of treatment. Black diamonds of this carat weight and certification are typically opaque or near-opaque due to the high concentration of graphite and structural defects that create their dark coloration.
