3.62 Ct. Greenish Yellow Cabochon Chrysoberyl from Tanzania

This translucent greenish yellow chrysoberyl weighs 3.62 carat and presents an elegant oval outline with measured dimensions of 8.55 x 7.36 x 6.06 mm, offered as a cabochon cut that emphasizes internal glow and optical phenomena. The body color reads as a balanced greenish yellow with medium color intensity, lending the stone a refined palette that performs well under both natural daylight and controlled gallery illumination. Clarity is evaluated at eye level as very slightly included, and the inclusions are sufficiently minor to preserve a clean visual appearance across the dome while also contributing to the gem character. The polish is rated excellent, the surface exhibiting a smooth, glasslike finish without visible polish lines when viewed with normal loupe inspection, and there has been no enhancement to alter color or clarity, confirming that the material is wholly natural from Tanzania.

From a lapidary perspective this cabochon demonstrates well considered cutting and finishing decisions that optimize both durability and aesthetic performance. The oval form maintains consistent symmetry and proportional outline, with a dome height calibrated to deliver a pleasing balance between translucency and body color saturation. The cutter has achieved intimate contact between optic and exterior by orienting growth structure parallel to the dome axis, a technique that maximizes any chatoyant response while minimizing windowing and color washout. The high quality polish is indicative of staged abrasive progression, likely culminating in a fine diamond paste or cerium oxide finishing regimen, resulting in crisp reflective highlights and even light return across the surface.

Optical and material properties of chrysoberyl underlie the gemological appeal of this example, and these characteristics are relevant for collectors focused on technical excellence. Chrysoberyl is a hard and dense species with a Mohs hardness near 8.5, and the refractive index typically lies in the range of approximately 1.746 to 1.755 with low birefringence near 0.008 to 0.010, parameters that contribute to its resistance to wear and ability to take a fine polish. The subtle internal inclusions that yield the very slightly included clarity grading can also act as the structural elements that produce a single cat eye or silk band when the stone is well oriented, a phenomenon produced by oriented, fine needle like or fibrous inclusions that reflect light in a narrow, well defined band. For practical use the stone is robust enough for daily wear when set in protective mounting styles, and a bezel setting is recommended to shield the cabochon edges and to present the dome with stable light interaction.

As a collectible piece this 3.62 carat Tanzanian chrysoberyl cabochon is a strong candidate for inclusion in a high end gemstone collection where both aesthetic subtlety and lapidary integrity are prioritized. The combination of natural, unenhanced origin, medium color intensity, excellent polish, and a carefully executed cabochon profile elevates its market position, while the very slightly included clarity preserves both value and visual interest. Collectors seeking stones with provenance and technical merit will appreciate the materiality and finish, and The Natural Gemstone Company stands behind the provenance and description supplied, providing this gem as a well documented, well finished example of chrysoberyl that integrates classic gemological attributes with artisanal cutting quality.
