3.89 Ct. Bi Color Rough Sapphire from Ceylon (Sri Lanka)

This translucent 3.89 carat, rough shape, bi color sapphire measures 17.50 by 6.00 by 4.50 mm, and presents an elongated, tapered crystal habit with subtle color zoning. The stone displays light color intensity, with areas ranging from pale golden to muted bluish tones that are typical of certain Ceylon deposits. The piece has no traditional faceted cut, its surfaces have been given an excellent polish that preserves the natural contours of the crystal while improving luster and tactile quality. Clarity is graded as slightly included, evaluated at eye level, and no enhancement has been performed, confirming an unaltered material from its origin in Ceylon, Sri Lanka. The Natural Sapphire Company documents this sapphire as a natural, unenhanced example suitable for collectors and designers who value original crystal form and natural color distribution.

The internal inclusions visible in this specimen are important features that contribute to its identity and provenance, they appear as growth zoning, thin veils, and linear internal features that trace the crystal growth and color transition. These inclusions act as natural fingerprints, useful for gemological characterization and for distinguishing this stone from treated or synthetic material, they also enhance the stone character by providing depth and a three dimensional interplay with transmitted light. From a practical perspective these internal features inform potential cutting and setting decisions, they may guide orientation for a polished cabochon or creative slice that highlights the bi color effect while preserving structural integrity. For care, gentle cleaning with warm soapy water and a soft brush is recommended, avoid steam and harsh chemicals to maintain the natural surface polish. This sapphire offers a distinctive, responsibly sourced option for bespoke jewelry and collection pieces, and The Natural Sapphire Company can provide additional gemological information and imagery to assist in design planning and provenance documentation.
