3.58 Carat Natural Black Heart Diamond GIA

This 3.58 carat diamond is a natural fancy black with no overtone, fashioned in a heart shape. The stone is untreated and certified by the GIA as a loose diamond. Black diamonds of this size and color saturation are relatively uncommon in the market. The heart cut presents distinctive optical properties characteristic of fancy black diamonds, which derive their color from graphite inclusions and structural defects within the crystal lattice.
