0.65 Carat Natural Black Oval Diamond GIA

This 0.65-carat black diamond is a loose stone certified by GIA as Fancy No Overtone Black, indicating the stone's color derives from graphite inclusions and structural defects rather than colored diamond grading factors. The oval cut is a common choice for black diamonds, as the shape can help distribute color evenness across the stone. The diamond is untreated, meaning no artificial enhancements have been applied to improve appearance. As a loose stone, it is available for custom setting or independent appraisal.
