1.47 Ct. Cabochon Chrysoberyl from Ceylon (Sri Lanka)

This single translucent brown chrysoberyl, offered by The Natural Gemstone Company, is a 1.47 carat oval, with exact dimensions of 6.52 by 6.55 by 3.68 millimeters, executed as a cabochon. The shaping is a true oval profile, with symmetry maintained within one or two hundredths of a millimeter across the length and width, which preserves optical uniformity and consistent table presentation. Clarity is graded as very very slightly included when evaluated at eye level, indicating only minute internal features that do not interrupt the gem body or its overall translucency. Color presents as medium intensity brown, with balanced saturation that reveals subtle tonal variation across the dome as the viewing angle changes. Polish is excellent, producing a smooth surface that enhances surface reflection and allows the inherent body color to read cleanly, with no evidence of treatments or enhancements, and with origin documented as Ceylon Sri Lanka.

From a gemological perspective, chrysoberyl offers a combination of optical and physical properties that make this specimen technically interesting and practical for fine jewelry applications. Chrysoberyl has a high refractive index and strong luster relative to many other semiprecious species, and its hardness is approximately 8.5 on the Mohs scale, which gives good resistance to abrasion and wear. The translucency of this cabochon indicates light diffusion through the material, rather than full transparency, and this interacts with the domed cut to produce an even color plane and localized highlight zones. The lack of enhancement for color or clarity assures that the observed optical behavior is wholly natural, a characteristic highly valued by connoisseurs who focus on untreated Sri Lankan gem material, which often displays a muted, earthy palette and fine internal character.

The craftsmanship displayed in the cabochon cutting is specific and intentional, with technical choices made to balance depth of color against light return. The cutter selected a moderate dome height to maximize the visibility of the medium brown hue while avoiding overly deep saturation that can render the interior darker and less lively. Edge and girdle transitions are tapered and smoothly blended into the base, which facilitates secure bezel mounting and reduces the risk of stress concentration during setting. The excellent polish results from sequentially applied abrasives calibrated to chrysoberyl hardness, concluding with a finishing lap that minimizes microscopic surface imperfections and yields the clean reflections visible in the photographs. The clarity grade of very very slightly included at eye level suggests that the cutter positioned the cabochon to conceal or render inconspicuous any internal features, a common practice when working with translucent material where internal dynamics contribute to character rather than detract from value.

For design and setting considerations, this oval cabochon of 1.47 carats and near equal dimensions across length and width makes an excellent focal stone for rings, pendants, and bespoke pieces where the brown color can be complemented by warm metal tones. Bezel settings are technically preferable for cabochons, providing a continuous edge that protects the soft curve and distributes mechanical stresses during wear, while prong settings can be employed where the design allows collar style retention and protection for the dome. Given chrysoberyl hardness, routine wear is feasible, though recommended care includes avoiding harsh ultrasonic cleaning and sudden thermal shocks, and using warm water with mild detergent and a soft brush for periodic maintenance. At The Natural Gemstone Company we document origin and treatment status, and we stand behind the natural provenance and the no enhancement declaration for this stone, which will interest collectors and professional jewelers seeking natural Ceylon chrysoberyl with precise cutting and verified characteristics.
