6.91 Ct. Bluish Grey Sapphire Crystal from Ceylon (Sri Lanka)

This semi translucent bluish grey sapphire weighs 6.91 carat and measures 26.67 x 6.13 x 4.91 mm, its elongated various shape and rough crystal cut preserve the natural form and termination that make material from Ceylon desirable to collectors and designers, the stone displays a light color intensity with subtle bluish grey tones that read differently under varied lighting, clarity is graded as very slightly included evaluated at eye level which indicates only minor internal features that do not compromise structural integrity, polish is excellent producing a clean surface luster, and importantly this sapphire has undergone no enhancement which is a key factor for many informed buyers seeking natural provenance and value. Origin is Ceylon Sri Lanka, a region renowned for producing sapphires with fine crystalline structure and a wide range of blue tones, the combination of natural crystal habit and untreated status gives this specimen appeal both as a collector crystal and as a centrepiece for bespoke jewellery.

From a gemological perspective the attributes of this stone explain its appeal and value, the corundum species has a Mohs hardness of nine which ensures durability for wearable settings while the rough crystal cut and semi translucency provide a unique aesthetic different from precision faceted stones, very slightly included clarity means inclusions are minimal at standard visual inspection and often contribute to character without materially reducing brilliance, light color intensity results in a softer, more understated appearance that suits elegant pendant or modern, minimalist ring designs where color subtleties are appreciated. For educated buyers the absence of heat or other treatments increases rarity and market desirability, provenance from Ceylon carries historical and trade significance and often commands a premium when paired with transparent disclosure, at The Natural Sapphire Company we prioritise accurate descriptions and can assist with mounting recommendations to highlight the stone length and tapered profile while protecting delicate points, we also offer independent certification services upon request to document natural origin and non enhancement status, this sapphire is well suited to someone seeking a distinctive natural crystal with strong provenance, sound gemological credentials, and the enduring qualities of untreated Ceylon corundum.
