6.91 Ct. Bluish Grey Star Sapphire from Ceylon (Sri Lanka)

This translucent bluish grey star sapphire weighs 6.91 carats, and measures 10.85 x 9.21 x 5.82 mm, presented in an oval cabochon shape. The gem displays a light color intensity that allows the inherent luminosity to read softly across the dome, and it exhibits a distinct six rayed asterism that becomes apparent and well centered under direct light. Clarity is graded as slightly included when evaluated at eye level, with internal features consistent with natural formation, and no enhancement has been applied to alter its appearance. The cabochon cut has been executed to optimal proportions, with an excellent polish that enhances surface reflectivity and improves the contrast and definition of the star. Origin is Ceylon Sri Lanka, a provenance noted for producing quality star sapphires with fine asterism.

The exceptional cut and finish position this stone as an immediate centerpiece for a variety of settings, with the symmetry of the oval proportions and the clean domed surface contributing to a strong central star that commands attention. The controlled dome height and even polish maximize the chatoyancy and deliver a luminous, dynamic presentation as light moves across the surface, making the sapphire suitable for a signature ring or a pendant where the asterism can be shown to best effect. As an untreated natural sapphire supplied by The Natural Sapphire Company, this gem offers both aesthetic presence and the straightforward gemological attributes that collectors and designers rely on, combining a thoughtful balance of color, cut, and surface quality to present a refined example of Ceylon star sapphire craftsmanship.
