Natural Gray Star Sapphire Cabochon, 61.57 Carats – Sri Lanka

A commanding 61.57 carat natural gray star sapphire cabochon from Sri Lanka, measuring a substantial 21.44 x 10.37 x 14.86mm — a true statement stone for a serious collection or a one-of-a-kind piece. Cut in a high, well-domed cabochon, it displays a soft, silvery-gray body color with a translucent glow that lets light diffuse gently through the stone, and the six-ray star sits centered and legible under a single light source, sliding smoothly as the stone is turned.

Like all natural star corundum, the asterism comes from dense rutile silk oriented along the crystal's growth axes — in this stone, that silk is also responsible for the atmospheric, almost smoky translucency across the dome. This is an unheated, untreated stone, which is genuinely uncommon at this size; large star sapphires on the market are very often heat-treated to improve clarity or deepen color, so a natural 60+ carat piece with an intact, well-formed star is a rare find for collectors, museum-style displays, or a bespoke pendant designed to let the stone itself be the centerpiece.
