1.86 Ct. Purple Star Sapphire from Ceylon (Sri Lanka)

From the mineral veins of Ceylon Sri Lanka this purple star sapphire begins its life deep within metamorphic rock, formed over eons as aluminum rich layers were infused with traces of titanium and iron, and as tiny rutile needles aligned during growth, asterism was born. This one of a kind gem weighs 1.86 carat, and is cut to a classic cabochon oval measuring 6.92 by 6.13 by 4.16 millimeters, a profile chosen to honor the stone natural structure and to reveal its signature star. The material is translucent with an intense purple body color, an excellent polish that gives the surface a satiny sheen, and a clarity described as very very slightly included when viewed at eye level, a testament to its natural, untreated origin. No enhancement has been applied, the color and the star are entirely natural, and our team at The Natural Sapphire Company sources and presents this gem with complete transparency, celebrating its Ceylon provenance and timeworn story.

What makes this star sapphire unmistakable are the internal inclusions that form a precise six ray star that appears to float on the dome as light moves across the surface. Fine, oriented rutile silk threads create a velvety internal lattice, and in this specimen those silk inclusions intersect in a way that produces a crisp, centered asterism, giving the gem an almost lunar quality. Under direct light the star pins into view, a bright silk line that bisects the cabochon, then repeats along two additional axes to create the classic six armed star, while the purple body color shifts in tone from cool violet to warmer amethyst as the angle changes. These inclusions are the gem fingerprint, they guide the cutter in shaping the cabochon, they influence how the star travels across the surface, and they lend the sapphire a character that cannot be replicated by treatment or imitation. For collectors and designers who value story and natural rarity, this Ceylon purple star sapphire is ready to be set as a focal ring, a pendant, or a bespoke commission, and our gem specialists at The Natural Sapphire Company are available to advise on settings that will showcase the star and preserve the gem integrity.
