7.29 ct Black Sapphire-Star - Cabochon

This 7.29-carat star sapphire is shaped as a cabochon measuring 12.4 x 9.8 x 5.3 mm, with a black body color, sourced from Thailand.

A star sapphire carries fine silk inclusions that gather light into a star across the dome of the cabochon, a phenomenon gemologists call asterism. Thailand is both a corundum source and the great cutting and finishing hub of the colored gemstone trade. It carries no treatment of any kind, so the color you see is the color that came out of the ground.

This is a center-stone-grade gemstone with a character of its own, chosen rather than settled for. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
