0.58 Carat Natural Black Round Diamond GIA

This is a 0.58 carat round diamond with a GIA certification identifying it as Fancy No Overtone Black. The stone is untreated natural diamond offered as a loose stone. Black diamonds of this type derive their color from graphite inclusions and structural defects rather than traditional color-causing elements. The round cut is a common choice for black diamonds, as the faceting can emphasize the stone's depth of color.
