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

This listing describes one translucent 0.72 carat oval purple star sapphire, measuring 5.61 x 4.04 x 3.40 mm, cut as a classic cabochon to display asterism. The stone exhibits medium color intensity in a clear purple hue, with translucency that allows light to interact with internal features to reveal a distinct, centered star when viewed under direct light. Clarity is graded as slightly included at eye level, with natural internal silk and minor surface reaching inclusions that are consistent with the photographed profile views, and these inclusions contribute to the gemological character without compromising the star effect. The surface shows an excellent polish, enhancing light return and the visibility of the star, and no enhancement has been applied to this material. Origin is Ceylon, Sri Lanka, a historically significant source known for star sapphire occurrences, and the stone presents the expected combination of natural inclusions and optical phenomena associated with such provenance.

From a practical perspective, the gem is well suited to applications that maximize viewing of the star, such as a pendant or a ring with a secure bezel or low profile setting that protects the dome while orienting the stone to receive direct light. At 0.72 carat and with dimensions of 5.61 x 4.04 x 3.40 mm, the sapphire is compact and will sit comfortably in most mounting designs, while its cabochon geometry and excellent polish facilitate strong asterism when properly oriented. The inherent durability of corundum, with a Mohs hardness of 9, makes this sapphire appropriate for regular wear given reasonable protection from sharp impacts. The Natural Sapphire Company stands behind the material description and is available to provide further guidance on mounting options, appraisal considerations, and additional imaging to confirm orientation and appearance under different lighting conditions. This presentation emphasizes the gemstone attributes and specifications to assist in informed evaluation, with a focus on the quality of the star effect, the natural origin, and the unenhanced state of the stone.
