1.72 Carat Natural Black Heart Diamond GIA

This 1.72 carat heart-shaped diamond is graded by GIA as Fancy No Overtone Black, indicating the stone displays a pure black color without secondary hues. The diamond is untreated and offered as a loose stone, allowing for independent evaluation of its optical properties. Black diamonds of this carat weight and shape are typically achieved through high concentrations of graphite and other inclusions throughout the crystal structure, which creates the opaque black appearance characteristic of the variety.
