12.03 Ct. Grey Star Sapphire from Ceylon (Sri Lanka)

This extraordinary, one of a kind grey star sapphire, offered exclusively by The Natural Sapphire Company, weighs 12.03 carats and presents an elegant oval silhouette, measuring 13.38 x 10.16 x 8.77 mm. Cut as a classic cabochon to reveal its celestial asterism, this translucent gem displays a clear six ray star that glides across the surface with even movement as it meets light. The stone shows medium color intensity, a serene grey that shifts subtly in different lighting, and an excellent polish that enhances the silky, reflective surface. Origin Ceylon Sri Lanka adds a storied provenance to the piece, linking it to a long heritage of world class sapphires, while the absence of enhancement guarantees that what you see is the natural character of the gem, preserved and untreated.

Evaluated at eye level, the clarity is slightly included, a natural signature that testifies to the gemological journey of this sapphire and contributes to its individuality and depth. The cabochon form and the slight inclusions work together to strengthen the star phenomenon, producing a focused, luminous star that will remain the centerpiece of any bespoke setting. This is not a mass produced item, but a rare single specimen, ideal for collectors, connoisseurs, and clients seeking an exclusive commission piece that will not be replicated. At The Natural Sapphire Company we offer personalized design consultation, and we can advise on mounting options that respect the proportions of the 13.38 x 10.16 x 8.77 mm oval, preserving the integrity of the star and maximizing visual impact. Owning this sapphire places you among an elite group who appreciate natural rarity and the quiet power of a stone that is both subtle and striking. For those who desire a gemstone with authenticity, provenance, and exceptional presence, this Ceylon star sapphire represents a rare opportunity to acquire a naturally formed marvel, unmarred by enhancement, ready to be transformed into a singular heirloom.
