0.68 Ct. Bluish Grey Star Sapphire from Ceylon (Sri Lanka)

This beautiful translucent 0.68 carat oval bluish grey star sapphire from Ceylon Sri Lanka is a finely proportioned cabochon, measuring 5.15 by 4.31 by 2.84 millimeters, with an excellent polish that enhances its luster and asterism. The gem has been evaluated as very very slightly included at eye level, reflecting a clarity that is exceptional for asteriated sapphires where oriented needle inclusions produce the star rather than detract from the appearance. The light color intensity allows a distinct white star to form and glide across the dome when viewed under a single light source, a characteristic owed to an ideal balance between translucency and internal silk. There has been no enhancement to this stone, so the color, clarity, and star are entirely natural, and the cabochon shape and dome height were chosen to maximize the visibility and sharpness of the star while preserving the gem weight and overall proportions.

For the educated buyer this specimen represents a convergence of rarity factors that increase both aesthetic appeal and collectability. Bluish grey star sapphires are less common in the market than classic cornflower blue or deep black star material, and finding an untreated Ceylon stone in the 0.5 to 0.8 carat range that combines translucency, a clear centered star, and very very slight eye level inclusions is unusual. Ceylon Sri Lanka is historically renowned for producing finely asteriated sapphires with good silk alignment, and provenance from this source is a meaningful attribute for connoisseurs. The untreated status increases rarity and long term value compared with heated or otherwise enhanced material. This gem will perform beautifully as an elegant single stone in a minimalist ring or as a refined pendant accent where the star can be showcased, and its modest dimensions make it versatile for custom settings. At The Natural Sapphire Company we provide detailed imaging and evaluation so you can assess the asterism, color tone, and proportions, and we are available to advise on mounting options that preserve and emphasize the star effect while protecting the cabochon.
