1.25 Carat Natural Black Round Diamond GIA

This is a 1.25 carat round diamond with a GIA certification identifying it as Fancy No Overtone Black. The stone is untreated and offered as a loose diamond. Black diamonds of this type derive their color from graphite inclusions and structural defects throughout the crystal lattice rather than from elemental impurities. The round cut is a standard choice for maximizing the visual impact of darker stones.
