1.23 Ct. Purple Star Sapphire from Ceylon (Sri Lanka)

This specimen is a translucent oval shape star sapphire weighing 1.23 carats, with precise dimensions of 5.58 x 5.09 x 4.06 mm, cut as a domed cabochon to maximize asterism. The cutter has preserved a high, evenly curved dome and a well centered apex, which optimizes the convergence of oriented inclusions that produce the star. Color is evaluated as medium intense purple, exhibiting even saturation across the table and crown, with good translucency that allows the star to appear crisp without excessive washout. Polish is excellent, resulting in a glossy surface that enhances light return and star contrast, and there are no surface-reaching abrasions or polishing pits visible at standard loupe magnification. No enhancement has been applied, the material is natural and stable, and documented origin is Ceylon, Sri Lanka, a provenance known for producing strong asterism in corundum.

The asterism is generated by a dense, oriented network of silica stabilized rutile needles, producing a well defined six rayed star that centers cleanly under a single point light source and migrates predictably with movement, indicating good internal orientation and symmetry in the cabochon profile. Clarity is graded slightly included at eye level, with fine silk and a few minor dark crystal inclusions confined below the dome that do not materially detract from the visual star effect, and indeed contribute to its contrast. The gematic proportions, specifically the 4.06 mm depth relative to the 5.58 mm length, provide sufficient body to carry the star while maintaining wearable size for a ring or pendant setting. For mounting considerations, the high dome and centered star favor a setting that presents the dome to a single overhead light, and a secure bezel or partial bezel will protect the cabochon while preserving the aesthetic of the asterism. This untreated, medium intense purple star sapphire from Ceylon is offered by The Natural Sapphire Company, and will appeal to connoisseurs who value natural asterism, meticulous cabochon cutting, and transparent treatment disclosure.
