2.30 Carat Natural Black Round Diamond GIA

This is a 2.30 carat round diamond certified by GIA as Fancy No Overtone Black with no documented treatments. The stone is offered as a loose diamond. Black diamonds of this size and weight are typically achieved through either natural color-causing graphite inclusions or irradiation treatments, though this example carries no treatment notation in its specifications. The round cut maximizes the visual presence of darker stones while allowing for standard brilliant faceting.
