1.36 Carat Natural Black Emerald Diamond GIA

This is a 1.36-carat diamond with a Fancy No Overtone Black color grade, cut in an emerald shape. The stone is natural and untreated, certified by GIA, and is offered as a loose stone. Black diamonds of this size and purity are relatively uncommon in the market, as the color saturation typically requires significant graphite content throughout the crystal structure.
