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

This listing presents a natural purple star sapphire weighing 0.60 carat, presented in an oval cabochon form with precise dimensions of 4.55 by 4.24 by 3.01 millimeters. The gem displays a translucent body and a medium intense purple color that reads consistently across the crown and girdle, providing a balanced, elegant hue. The cabochon cut enhances a distinct star phenomenon, or asterism, which is visible as a fine, six-rayed star across the dome under direct, single-point lighting. The polish is graded as excellent, producing a smooth lustre that supports strong light return and clear delineation of the star, while the clarity is graded as very slightly included when examined at eye level, with internal features that are typical for natural star sapphires and that contribute to the character of the gem rather than detract from its appearance.

The origin of this star sapphire is Ceylon, also known as Sri Lanka, and the stone has not undergone any enhancement. No heat treatment or other modifications have been applied to alter the color or the asterism. The presence of the star is attributable to oriented needle-like inclusions of rutile within the corundum, and the lack of enhancement preserves the natural textures and growth features associated with Ceylon sapphires. The combination of natural origin, absence of treatment, and a well-centered asterism is of interest to collectors and connoisseurs who prioritize provenance and natural state. The dimensions and modest carat weight make this gem well suited for a focused design application where the star can be positioned as the visual center, and where the intact natural character of the stone is an integral part of the finished piece.

From a practical standpoint the inherent toughness of corundum, which ranks at nine on the Mohs scale, makes this star sapphire suitable for a variety of jewelry settings that protect the cabochon while allowing the star to be seen clearly. A setting that provides a stable seat and some protection to the girdle is recommended, given the cabochon profile and the small but meaningful table height. Routine care can be undertaken with warm, soapy water and a soft brush, and exposure to extreme chemicals and prolonged high heat should be avoided to preserve the stone and any surrounding materials in the finished setting. The Natural Sapphire Company provides this gem with documentation of its stated characteristics and origin, supporting informed selection and integration into custom or ready-made designs, and the piece is presented with an objective assessment of its optical and physical attributes for accurate comparison with other stones.
