2.70 Ct. Purple Cabochon Star Spinel from Ceylon (Sri Lanka)

This exquisite opaque 2.70 carat round purple star spinel is a rare treasure from Ceylon, Sri Lanka, offered exclusively through The Natural Gemstone Company. Measuring 7.34 x 7.32 x 5.07 mm and fashioned in a classic cabochon, this stone displays a medium color intensity with a velvety purple that reads as both regal and mysterious. The clarity grade is very very slightly included, evaluated at eye level, and the excellent polish allows light to play across the dome without interruption. With no enhancement and a natural origin, this single piece stands as a one of a kind example of the finest star spinel material, a gem reserved for collectors and connoisseurs who insist on authenticity and singularity.

The natural asterism is the defining feature, presenting as a precise, six rayed star that sits crisply at the heart of the cabochon, formed by fine parallel silken inclusions that intersect to cast star like rays across the surface. Under strong direct light, such as midday sun or a focused gem lamp, the star sharpens into a bright, pin point motif that appears to glide across the dome as the stone is tilted. Under cool LED or halogen illumination, the star remains tight and vivid, the rays slicing cleanly through the purple body color. In softer, diffused lighting the asterism relaxes into a ghostly, shimmering star, while the overall purple deepens and becomes more enveloping, giving the gem a secretive, inner glow. Under warm incandescent or candlelight the purple takes on warmer undertones and the star softens slightly, offering an intimate and romantic presence. The cabochon cut and the impeccable polish maximize these effects, allowing the star to respond clearly to light direction and intensity, so the wearer can enjoy a dynamic, living jewel that reveals new facets of its personality in every environment.

This spinel is offered in strictly limited quantity, a single, museum worthy specimen. Contact The Natural Gemstone Company to reserve this rare star spinel and to explore bespoke mounting options that will honor its extraordinary optical display.
