4.96 Carat Natural Black Round Diamond GIA

This 4.96 carat round diamond is graded Fancy No Overtone Black by the Gemological Institute of America, indicating a natural black coloration without secondary hues. The stone is untreated and offered as a loose diamond, allowing for independent evaluation and custom setting options. Black diamonds of this size and quality are relatively uncommon in the market, as the color results from numerous graphite inclusions and structural defects throughout the crystal lattice rather than trace elements. GIA certification provides documentation of the diamond's characteristics and lack of treatment.
