10.23 Carat Natural Black Round Diamond GIA

This is a 10.23 carat round diamond with a Fancy No Overtone Black color grade, certified by GIA as untreated. The stone is offered loose, allowing flexibility for custom setting. Black diamonds of this size and carat weight are relatively uncommon in the market. The round brilliant cut is a traditional choice for maximizing light reflection, though black diamonds do not display the spectral dispersion typical of colorless diamonds.
