23.93 Ct. Yellowish Brown Sapphire Crystal from Ceylon (Sri Lanka)

This listing describes a substantial, semi transparent yellowish brown sapphire from Ceylon, weighing 23.93 carats. The stone measures 22.20 x 13.60 x 9.90 millimeters, and presents in a various shape form that reflects its natural crystal habit. The piece retains a rough crystal cut, evidencing original growth faces and a facetted profile that has been minimally altered. Color intensity is classified as medium intense, producing a warm, earthy tone that reads yellow to brown depending on light and viewing angle. The combination of size and semi transparency allows for appreciable light transmission while maintaining the organic character of a natural, untreated gem. The Natural Sapphire Company is offering this specimen as a collector grade rough crystal or as a potential preform for custom cutting by an experienced lapidary.

Clarity is graded as included, evaluated at eye level, and the stone contains internal features that are visible without magnification. These inclusions are consistent with natural formation and contribute to the stone character, presenting as discernible internal structure and localized opacity in places. Despite the presence of these inclusions the overall polish is excellent on the available surfaces, with well defined natural facets and smooth areas that reflect light cleanly. The semi transparent nature of the sapphire means that the inclusions affect the gem appearance more than they would in a fully transparent stone, but they do not overwhelm the material and in many cases add to the specimen quality by confirming its natural origin. Photographic views show the crystal from multiple orientations, highlighting the asymmetry and the way light interacts with the internal features and external faces.

No enhancement has been applied to this sapphire, it is presented in its natural state with no heat treatment, diffusion, fracture filling, or other laboratory interventions. This untreated status is important for provenance and for buyers who prioritize natural state material, as the absence of enhancement affects both rarity and potential market valuation. The origin is reported as Ceylon, Sri Lanka, a region internationally recognized for producing a wide range of sapphire colors and qualities. Ceylon sapphires are noted for their diverse color palette and clarity characteristics, and this yellowish brown material is consistent with the variety of hues found in Sri Lankan mines. For clients who are considering this sapphire for bespoke work or for investment and collection purposes the untreated origin and substantial carat weight make it a distinct example of natural Ceylon material.

Given the weight and dimensions this sapphire offers several practical options for further work or display. For lapidaries and cutters who wish to maximize retainable weight a careful re shaping and minimal faceting approach may yield a large free form gem, while a skilled cutter could also evaluate potential for a classic oval or cushion faceted stone that balances color distribution and inclusion masking. Alternatively the piece could be fashioned as a cabochon to exploit the warm color and provide a smooth surface that emphasizes tone over brilliance. As a rough crystal specimen the stone also suits connoisseurs who prefer to retain natural crystal form and display it as part of a collection. Handling and setting recommendations include using protective settings that account for the included clarity and the semi transparent body, and advising routine care such as gentle cleaning with mild soapy water and avoiding abrasive treatment.
