1.05 Ct. Greyish Blue Star Sapphire from Ceylon (Sri Lanka)

One beautiful translucent 1.05 carat oval greyish blue star sapphire from Ceylon Sri Lanka presents as an oval cabochon with dimensions of 6.51 by 4.92 by 2.92 millimeters, a cabochon cut that has been executed to exacting proportions to maximize asterism and surface luster. The stone exhibits medium color intensity, a greyish blue tone that is both versatile and refined, and a clarity grade of very very slightly included evaluated at eye level, with fine oriented rutile silk that is typical of natural star sapphires and that generates a distinct star phenomenon when viewed under direct light. The asterism is visible across the domed surface due to precise symmetry of the cabochon profile and an excellent polish that enhances both the soft translucency of the body color and the contrast of the star. No enhancement has been applied to this gem, and its untreated status combined with a Ceylon Sri Lanka origin provides provenance that many discerning buyers seek.

For engagement jewelry this star sapphire is an exceptional option because of corundum hardness and toughness, a hardness of nine on the Mohs scale which ensures long term wearability for an everyday ring. The oval cabochon silhouette sits comfortably in bezel and rub over settings, where the smooth dome protects the stone while allowing the asterism to align with overhead light, and this profile also lends itself to bespoke designs that highlight the star with a simple solitaire bezel or a refined halo that adds visual weight without obscuring the light responsive effect. The stone measures precisely for ring mounting, and the 6.51 by 4.92 by 2.92 millimeter dimensions allow experienced setters to center the star through orientation during setting, maintaining symmetry and maximizing the optical impact. As presented by The Natural Sapphire Company this 1.05 carat greyish blue star sapphire is an ideal engagement choice for a buyer who values technical quality, natural untreated material, and the interplay of cut, clarity, and surface polish that produces a lasting and wearable focal gemstone.
