Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 3.26 carat purple star sapphire displaying a six-rayed asterism, cut as an oval cabochon, completely unheated, with a GIA report. The six-rayed star is caused by aligned rutile needles within the corundum crystal — when illuminated by a single directional light source (flashlight, sunlight, spotlight), the needle inclusions reflect a sharp, silver-white star that crosses at the apex of the cabochon. This stone's purple body color creates a dramatic contrast with the silver star, a pairing that makes purple star sapphire one of the most visually striking phenomenon gemstones available.
Important: the star is only visible under direct single-source light — sunlight, flashlight, or a spotlight. It will not appear under diffuse room lighting.
Why Choose this 3.26 ct Unheated Purple Star Sapphire?
At 3.26 carats with a GIA report and unheated status, this sits at the premium end of star sapphire collecting. The GIA report confirms the asterism phenomenon, weight, and dimensions — documentation that is rare for star sapphires, which are typically sold without formal certification. The purple body color is less common than gray or blue star sapphires, and the oval cabochon shape allows the star to be viewed from multiple angles without the restrictions of a round.
