4.88 Ct. Grey Star Sapphire from Ceylon (Sri Lanka)

This is a beautifully translucent grey star sapphire from Ceylon, Sri Lanka, presented by The Natural Sapphire Company, weighing 4.88 carat, in an oval shape with dimensions 11.79 by 9.79 by 4.39 mm, cut as a cabochon to maximize asterism and overall visual appeal. The gem is lab classified as Grey by the certifying laboratory Other, and it carries a clarity grade of very slightly included as evaluated at eye level, which indicates that inclusions are minimal and do not detract from the star effect when viewed unaided. Color intensity is described as intense, which in a grey sapphire means the tone and saturation work together to present a strong, even body color that allows the six rayed star to appear crisp. The polish is excellent, which is essential for a star sapphire because a smooth, well finished dome yields the sharpest and most centered asterism. There has been no enhancement, this stone is untreated, and its natural state is documented on the accompanying certificate, making it an especially desirable choice for buyers who prioritize provenance and authenticity.

For an educated buyer, this specimen offers several clear strengths that justify its value, starting with origin, which matters in both market perception and gem character, because Ceylon sapphires are renowned for their combination of clarity and satiny silk that produces strong asterism. The relatively large weight of 4.88 carat in an oval cabochon is notable, because well proportioned star sapphires of this size with intense color and minimal eye visible inclusions are uncommon. The very slightly included clarity grade indicates that the internal rutile silk and any other features are fine enough to support a sharp star without causing obvious cloudiness, which enhances both visual appeal and light performance. The lack of enhancement adds a premium for collectors and connoisseurs who seek natural material, and the excellent polish and dome height are indicators that the cutter optimized the piece for a centered, six ray star. Practical considerations include durability, as corundum is second only to diamond in hardness, making this stone suitable for a variety of fine jewelry settings, and versatility, since the neutral grey tone pairs elegantly with both white and yellow metals. At The Natural Sapphire Company we document these characteristics fully, and we welcome inquiries about secure mounting options and viewing guidance to help ensure this star sapphire meets your exact expectations.
