18.97 Ct. Blue Star Sapphire from Ceylon (Sri Lanka)

From the ancient alluvial terraces of Ceylon Sri Lanka this blue star sapphire began its journey as a hidden marvel beneath layers of river gravel and time, a patient miner's luck uncovered in a landscape that has produced some of the world most beloved sapphires, a place where folklore and geology meet. Local miners sifted and washed the gravels by hand, following veins of corundum with careful intuition passed down through generations, and when a pale blue rough appeared it carried with it the slow history of heat and pressure that built its crystalline heart. The stone arrived to our cutting house as a translucent crystal with promise, a specimen that would reveal its star only if respected in the process of shaping and polishing. In Ceylon there is a reverence for these stones that is cultural as much as practical, a belief that certain sapphires hold the weather and the sea within their color, and that tradition informed every step taken on this gem until it reached the hands of our master cutters.

Under the steady eye of an experienced lapidary the rough was evaluated and coaxed into an elegant oval cabochon to best reveal the internal silk and the asterism that defines a star sapphire. The resulting gem weighs 18.97 carats, and measures 14.86 x 12.39 x 9.40 mm, dimensions chosen to maximize both face up presence and the graceful dome needed for a clear star. The cutter worked to preserve translucency and to center the silk inclusions so that the light catches a single, sharp star that travels smoothly across the surface as the stone is tilted, a living phenomenon that feels almost like a heartbeat. The clarity is graded very slightly included at eye level, a grade that speaks to natural character without distracting from its luminous blue, which presents with medium intense color. No enhancement was applied, allowing the sapphire to speak plainly of its origin and formation, and the final polish is excellent, a mirror that lets the asterism read with vivid contrast against a soft oceanic blue.

This gem is AGL certified, a guarantee that the stone has been examined and its natural origins and treatment status verified, and The Natural Sapphire Company proudly presents it with full provenance from Ceylon Sri Lanka. The lack of enhancement adds to the appeal for collectors and connoisseurs who value stones that are honest and unaltered. Imagine this cabochon set in a simple mounting that lets light find the dome, or cradled in a vintage inspired bezel where the star can be admired at every angle, each movement bringing a new spark to the surface. For those seeking a centerpiece with both history and personality this 18.97 carat blue star sapphire offers a rare combination of size, translucency, and an archetypal star effect, an heirloom quality gem that connects the wearer to centuries of gem lore and the skilled hands that shaped it.
