1.09 Carat Natural Black Marquise Diamond GIA

This is a 1.09 carat natural black diamond in a marquise cut, graded by GIA as Fancy No Overtone Black. The stone is untreated and offered as a loose diamond. Black diamonds derive their color from numerous inclusions and structural defects within the crystal lattice rather than from trace elements. The marquise shape emphasizes the stone's dark appearance while offering increased surface area compared to round cuts of similar weight.
