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

This listing describes one translucent purple star sapphire, weighing 0.71 carat, presented as an oval cabochon with dimensions 5.35 by 4.67 by 2.89 millimeters. The cutting style is a classic domed cabochon, executed to display the internal asterism and to maximize color uniformity across the surface. Clarity has been graded as very slightly included when evaluated at eye level, indicating that minor internal features are present but do not substantially detract from the gem’s overall appearance. Color intensity is medium, producing a reliably visible purple hue that remains consistent across different viewing angles. The polish is graded excellent, yielding a smooth, reflective dome that enhances the stone’s luster and the visibility of the star. No enhancement has been applied to this material, and the origin is Ceylon, Sri Lanka, a locale historically associated with high quality sapphires.

The specimen displays a distinct star effect when illuminated by a single, strong light source, the asterism appearing as a centered star on the dome surface. The star is readily visible on the provided images and remains apparent under direct lighting conditions, indicating well-aligned rutile inclusions that produce the optical phenomenon. Because the cabochon is well proportioned, the star remains relatively centered and maintains its form as the viewing angle changes, which is a desirable attribute in star sapphires. The combination of the medium intense purple body color and the sharp star creates a balanced visual presentation where both color and asterism are appreciable without one overpowering the other. Translucency allows partial light transmission, which contributes to the depth of the star and gives the gem a soft, satiny appearance under diffuse lighting.

From a practical and design standpoint the gem’s oval dimensions and modest 0.71 carat weight are suitable for a range of jewelry applications, including modest ring settings, solitaire pendants, and matched pairs for earrings where comparable pieces are available. The cabochon profile is best showcased in settings that expose the dome to light, such as open-backed bezels or prong settings that leave the crown unobstructed, permitting the star to be activated by direct illumination. Sapphire’s inherent hardness near 9 on the Mohs scale makes it durable for everyday wear, though the cabochon dome should be protected from hard knocks and abrasive contact to preserve polish and prevent chipping along the girdle. Routine cleaning may be accomplished with warm, soapy water and a soft brush. Given the presence of natural inclusions that generate the star, caution is advisable with ultrasonic and steam cleaning; although no enhancement has been applied to this stone, these methods should be used with discretion or avoided if any doubt exists about internal features or set mounting.
