1.49 Ct. White Star Sapphire from Ceylon (Sri Lanka)

This listing describes a single, translucent white star sapphire weighing 1.49 carats, cut as an oval cabochon with dimensions of 5.68 by 5.23 by 4.75 millimeters. The gem displays a near colorless body tone, and an overall appearance that reads as white with a subtle, cool overtone under neutral lighting. The cabochon shape has been executed to present a smooth, domed face and a well proportioned pavilion, qualities that preserve the stone surface and maximize the optical phenomenon for which star sapphires are prized. The polish is excellent, and the surface finish presents a clean, reflective plane that contributes to the crispness of the asterism. No enhancements have been applied to this stone, and it is offered in its natural state as sourced from Ceylon, Sri Lanka.

Under direct, focused light the stone displays a distinct six ray star, asterism produced by oriented rutile inclusions aligned within the sapphire crystal. The star is sharply defined on the dome, appearing centered when the cabochon is properly oriented to the light source, and it translates across the face of the gem as the viewing angle changes. The star contrast is influenced by the stone translucency, and in this specimen the balance between body translucency and rutile concentration delivers a bright, well centered star that reads clearly against the near colorless field. The cabochon geometry, including the height of the dome and the symmetry of the oval outline, has been shaped to present the asterism in an even and attractive manner, making the optical effect visible under everyday light as well as under more controlled illumination.

Clarity is graded very slightly included, evaluated at eye level, and those inclusions are consistent with the rutile silk and minor crystal features that cause the star phenomenon. These inclusions are natural and integral to the identity of asteriated sapphires, and in this example they are finely distributed enough to support a bright star while remaining unobtrusive in the overall appearance of the gem. The absence of enhancement confirms that the material has not been heat treated, diffused, or otherwise altered to modify color or optical properties, which preserves the natural formation and character of the stone. Origin is Ceylon, Sri Lanka, a source long recognized for producing high quality sapphires, including white and star varieties, and the provenance supports expectations for classic Ceylonese crystal habits and rutile silk orientations that generate strong asterism.

For practical use the stone is well suited to a range of jewelry, including rings, pendants, and bespoke pieces where the dome can be appreciated and protected. Settings that present the cabochon with the dome elevated and the face exposed to direct light will best showcase the six ray star, and protective bezels or low prongs are recommended to guard the polished surface. Routine care may be accomplished with warm soapy water and a soft brush, avoiding harsh chemicals and extreme thermal or mechanical shock. The Natural Sapphire Company can provide additional high resolution images and specific measurements on request, and we can assist with setting suggestions based on the dimensions and optical axis of the cabochon. This white star sapphire offers a naturally formed, untreated example of classic Ceylon asterism, presented with precise cutting and polish to make the star the defining visual feature.
