2.73 Ct. White Rough Sapphire from Ceylon (Sri Lanka)

This is a translucent, rough shape white sapphire weighing 2.73 carats, supplied by The Natural Sapphire Company, with exact dimensions of 13.40 x 6.70 x 3.40 mm. The sample is presented in its natural rough state, with a n slash a cut designation, and demonstrates the inherent qualities expected from Ceylon, Sri Lanka material. Color intensity is near colorless, yielding a clean palette that interacts with light primarily through surface luster and internal scattering rather than strong color saturation. Clarity is graded as included when evaluated at eye level, and inclusions are visible but do not compromise the overall structural integrity of the crystal. The surface exhibits an excellent polish on natural faces and facets where present, indicating that the material will respond well to lapidary work without exhibiting surface pitting or etch textures that impede polish. There has been no enhancement, so the stone retains its natural state, an important characteristic for collectors and connoisseurs seeking untreated gem material.

From a lapidary perspective this piece offers several technical opportunities and constraints, informed by the 13.40 by 6.70 by 3.40 mm profile. The elongated plan view and relatively shallow thickness favor designs that conserve weight while optimizing face up spread, such as elongated step cuts, long ovals, and shield shapes, or alternatively a carefully planned shallow mixed cut to balance dispersion and brilliance. Given the included clarity grade, strategic orientation of the finished gem along the cleanest crystal axis will minimize visible inclusions. The rough is amenable to both faceted and cabochon outcomes, and because the surface polishability is excellent, high luster cabochons are a particularly attractive option when retention of carat weight and translucency are priorities. If the cutter elects to remove inclusions, the trade off will be a reduction in carat weight from the 2.73 carats, however precise planning and modern preforming techniques can often retain a substantial proportion of weight while producing a face up gem with optical performance that belies the starting material.

Optical and physical properties reinforce the premium potential of this sample, and the Ceylon origin contributes directly to market perception and demand. Corundum is a trigonal crystal with robust physical hardness of Mohs nine, providing exceptional durability for everyday wear, and the refractive index range typical for sapphire gives the stone good light return even in near colorless material. White sapphire lacks strong pleochroism, so consistent orientation in cutting will render a predictable tone and light response across the table. The low to moderate internal features reflected in the included clarity grade interact with light to create subtle internal texture, which can be an attractive quality in translucent white material when left as a polished cabochon, or can be masked by pavilion faceting in a brilliant or mixed cut. The absence of heat or other enhancement is a critical specification, elevating this piece for buyers and designers who prioritize untreated provenance. Ceylon provenance historically aligns with clean crystal growth and crystalline clarity, making this specimen a representative example of untreated white sapphire from that region.

As a member of the inventory at The Natural Sapphire Company, this 2.73 carat rough white sapphire is presented with full technical transparency and service options for customization based on client priorities. For clients seeking maximum carat retention the recommendation is to consider a cabochon or a shallow step cut, which will preserve weight and emphasize translucency and luster. For clients seeking higher faceted brilliance and crisp windowing, careful preforming to align the table with the cleanest axis followed by a mixed brilliant pavilion is the recommended approach, with anticipated trade offs in final carat weight. We provide detailed cutting consultations, faceting schematics, and specialist cutter recommendations for those who wish to convert this rough into a finished gemstone. Documentation of origin and enhancement status accompanies each sale, and The Natural Sapphire Company can advise on setting styles that complement near colorless white sapphire, including bezel settings that showcase cabochons, three stone designs that use white sapphire to balance stronger colored gems, and bespoke mounting solutions that protect and present the finished stone to best effect.
