2.03 Ct.Tw.Total Carat Weight Greyish Blue Star Sapphire Pair from Ceylon (Sri Lanka)

This pair of natural star sapphires from Ceylon, presented by The Natural Sapphire Company, comprises two oval cabochons weighing 1.08 carats and 0.95 carats, with precise dimensions of 5.68 x 5.17 x 3.13 mm and 5.77 x 5.18 x 3.04 mm respectively. Both stones are classic cabochon cuts, exhibiting a rounded dome profile that is optimized to display asterism, the six rayed star produced by oriented rutile silk inclusions. The cabochon geometry, including the relatively shallow but well rounded domes, balances the path length for internal reflection with the visibility of the star, producing a distinct, centered star when illuminated from above. Clarity is graded included at eye level, which is consistent with the presence of fine silk and minor crystal inclusions that contribute to the asterism rather than detract from it. The body color is a greyish blue with medium color intensity, a hue range characteristic of Ceylon material, and the polish is excellent, giving smooth, lustrous surfaces that aid in defining the star sharpness and contrast against the translucent body.

From a gemological and practical setting standpoint these sapphires are unenhanced, natural stones with no heat or diffusion treatments, preserving their original silk network and optical phenomena. The rutile needle orientation is subparallel, producing the classic six ray star that is most visible under a direct point light source, and the translucency of the material allows the star to register cleanly without excessive washout. Measurements and dome heights are ideal for matched pair applications such as stud earrings or paired accents, where symmetry of size and star orientation is important. Given the included clarity, cabochon profile, and medium color saturation, recommended mounting strategies include low bezel or protective prong settings that permit top lighting while minimizing exposure to knocks, preserving the polish and asterism. For collectors and connoisseurs who prioritize provenance and natural optical features, these Ceylon star sapphires represent a technically refined example of asteriated corundum, combining measured proportions, natural silk driven asterism, and excellent surface finish.
