3.00 Ct. Grey Star Sapphire from Ceylon (Sri Lanka)

This translucent 3.00 carat oval grey star sapphire is presented as a cabochon with dimensions 8.39 x 7.42 x 4.40 mm. The gem exhibits a medium color intensity within a cool grey range, and a distinct six ray asterism is visible under direct light, resolving into a sharp star at the dome when illuminated. Clarity is graded as very slightly included when evaluated at eye level, with needle like rutile inclusions that are typical for star sapphires and which contribute to the stone s asterism rather than detract from its appearance. The cabochon shows an excellent polish and a well proportioned dome that balances the stone s translucency with the visibility of the star, making the optical phenomenon apparent without excessive opacity. Overall shape and proportions are appropriate for practical jewelry mounting while preserving the optical alignment of the star.

This star sapphire is unenhanced, with no heat treatment or other modifications reported, and its origin is Ceylon Sri Lanka, a region noted for producing classic asteriated sapphires. For setting considerations, a protective bezel or a low profile mounting is recommended to shield the cabochon dome from abrasion while allowing adequate light to reveal the star. Cleaning with warm soapy water and a soft brush is advised, avoiding prolonged exposure to harsh chemicals or ultrasonic cleaners as a precaution for any stone with rutile inclusions. This specimen is offered by The Natural Sapphire Company as part of our curated inventory of natural sapphires, and it will appeal to collectors and designers seeking a naturally asteriated example with clear provenance and no enhancements.
