AT GIA LAB FOR REPORT, WILL BE AVAILABLE IN A FEW WEEKS

A natural 7.98 carat gray star sapphire in a round cabochon, from Sri Lanka (Ceylon), completely unheated, with a GIA report in progress. This stone displays a six-rayed asterism — a sharp silver-white star that moves across the dome when illuminated by a single directional light source. The round cabochon format is the most classical shape for star sapphires, centering the star symmetrically on the dome for maximum visual impact. At 7.98 carats unheated from documented Ceylon origin, this stone sits at the premium tier of the star sapphire market.

STAR WILL ONLY BE SEEN UNDER DIRECT SUNLIGHT OR FLASHLIGHT.

Why Choose this 7.98 ct Unheated Round Gray Star Sapphire?

The round cabochon is the preferred format for star sapphires because the symmetric dome presents the six-ray star with equal arm length in all directions, making the phenomenon as visually balanced as possible. At 7.98 carats, the star is large enough to be clearly visible across a room under a single light source, and the GIA report — once issued — will confirm the asterism, the unheated status, and the Ceylon origin.
