1.43 Carat Natural Black Heart Diamond GIA

This 1.43 carat heart-shaped diamond is graded Fancy No Overtone Black by the Gemological Institute of America, indicating the stone's color falls within the black diamond category with no secondary hues. The diamond is untreated and sold as a loose stone, allowing for independent evaluation of its optical properties. Heart-shaped cuts in black diamonds are relatively uncommon and require precise faceting to display the stone's inherent color saturation effectively. GIA certification provides documentation of the diamond's weight, color grade, and natural origin.
