11.97 Ct. Bluish Grey Sapphire Crystal from Ceylon (Sri Lanka)

This translucent bluish grey sapphire, weighing 11.97 carats, presents an elongated various shape with precise dimensions of 25.88 x 9.97 x 5.92 mm, and a polished crystal cut that preserves the natural terminus and axial symmetry of the original crystal. The cut strategy emphasizes broad, smooth planes rather than faceted brilliance, producing even light transmission and accentuating subtle internal growth zoning and fluid color distribution, with a faint color intensity that registers as a cool, silvery blue in standard daylight. Clarity is graded as very very slightly included, evaluated at eye level, which indicates minimal to negligible surface reaching features visible only under acute observation, and an excellent polish has been applied to the crystal planes to optimize tactile smoothness and reduce microabrasion. This sapphire is reported unenhanced and of Ceylon Sri Lanka origin, qualities that preserve natural character and make the material especially desirable to connoisseurs who prioritize provenance and unchanged lattice chemistry.

From a durability perspective this corundum specimen is exceptionally well suited for daily wear, owing to sapphire s intrinsic 9 on the Mohs hardness scale which confers high resistance to scratching and abrasion. The absence of cleavage in corundum and the robust crystal integrity of this piece provide good toughness, though like all sapphires it will benefit from protective design choices to mitigate the risk of chipping from sharp lateral impacts. The excellent polish on the crystal cut reduces hanging edges that can catch on settings or clothing, and the unenhanced nature of the stone ensures color stability under thermal and chemical exposure typical of everyday use. Recommended mounting approaches include low profile bezels or guarded prong shoulders in platinum or 18 carat gold, to secure the elongated axis and protect terminal points, and routine maintenance can be managed with warm soapy water and a soft brush. Ultrasonic cleaning is generally acceptable for natural unenhanced corundum, however because inclusions are present at eye level a conservative approach is advised and a professional inspection by The Natural Sapphire Company is recommended before submitting to aggressive treatment. This sapphire combines natural provenance, precise polished crystal workmanship, and the intrinsic hardness of corundum to deliver a piece that is both technically interesting and eminently practical for everyday jewelry.
