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

This listing describes a single natural star sapphire from Ceylon, offered by The Natural Sapphire Company. The gem weighs 1.32 carats and is fashioned into an oval cabochon with dimensions of 6.50 x 4.85 x 4.01 mm. The material exhibits a translucent body, and the color is best described as a medium intense purple, showing a balanced mix of violet and lavender tones across the dome. The cutter has produced an excellent polish, resulting in a smooth, reflective surface that enhances both the color and the optical star. The stone has been evaluated as very slightly included at eye level, consistent with natural sapphire material of this type, and there has been no treatment or enhancement applied to alter the color or clarity of the piece.

Optical performance is a defining attribute of this specimen, with asterism presented as a distinct star when illuminated with a single point light source. The star appears centered on the dome and shows good definition and mobility as the light source or viewing angle changes, indicating well oriented rutile needle inclusions within the sapphire. The interaction between the oriented inclusions and the cabochon dome produces a fine, six ray star that is most pronounced when the angle of incident light is controlled, and the gem is examined against a neutral background. The translucent body contributes to the visibility of the star without overly masking internal features, and the medium intensity color provides sufficient contrast so that the asterism remains visible without being subdued by an overly dark tone. The very slightly included clarity grade reflects light scattering from natural inclusions, but these do not materially diminish the star effect or the overall eye appeal under typical viewing conditions.

From a cutting and practical perspective this oval cabochon balances weight retention with optical effectiveness. The proportions yield a pleasing dome height that supports the development of the star while preserving a clean silhouette suitable for a variety of settings. At 6.50 mm in length and 4.85 mm across, the gem is a versatile size, compatible with ring designs that protect the dome, as well as with pendant and brooch applications where the star can be presented face up and viewed easily. The excellent polish reduces surface diffusion and enhances luster, which helps in everyday wear and in settings that expose the surface to light frequently. Because the sapphire is untreated, its appearance reflects solely its natural formation and geological origin, which is often a consideration for collectors and for settings intended to emphasize natural character. The Natural Sapphire Company presents this stone with its measured specifications and visual assessment, suitable for professionals and connoisseurs seeking a well characterized example of a Ceylon purple star sapphire.
