3.03 Ct. Chrysoberyl from Tanzania

This transparent 3.03 carat chrysoberyl presents in an emerald cut shape with precise dimensions of 9.29 x 6.29 x 5.03 mm, offering a compact silhouette that balances presence and wearability. The gem displays a yellowish green hue with a medium intense color grade, judged for evenness and saturation across the table and pavilion. Clarity is graded as very very slightly included at eye level, indicating that any internal features are minor and do not interfere with the gem facing up in typical viewing conditions. The cutting is executed to an excellent polish, with facet junctions and bevels finished to minimize light leakage and to deliver clean facet reflections. There is no enhancement, the material is natural chrysoberyl sourced from Tanzania, and the combination of weight, color intensity, and untreated origin positions this example as a material of interest to connoisseurs and collectors who prioritize authenticity and geological provenance.

From a lapidary perspective the emerald cut used here is a traditional step cut that favors linear facets and broad planes, providing a calm, architectural appearance that emphasizes color and clarity over scintillation. The long rectangular table is framed by elongated step facets on the crown and a series of parallel steps on the pavilion, producing controlled light return that renders the yellowish green tone with clarity and depth. The truncated corners reduce the risk of chipping during setting, and the facet geometry has been tuned to the specific refractive index and birefringence of chrysoberyl to maximize face up color while preserving internal contrast. Chrysoberyl typically exhibits refractive indices in the high 1.74 range, a modest birefringence, and a Mohs hardness of about 8.5 which together inform the cutter on ideal facet angles and durable facet edges. In this example the cutter has calibrated crown and pavilion angles to limit windowing and to emphasize chroma, while the excellent polish supports crisp facet reflections and minimal surface diffusion, resulting in a stone that reads evenly vivid under both natural and controlled lighting.

For the discerning collector this chrysoberyl makes a technically compelling addition to a high end gemstone assemblage, its combination of weight, step cut, clarity grade, and untreated Tanzanian origin aligning with the priorities of rigorous collections. The emerald cut format allows the stone to be showcased in fine jewelry with settings that favor open galleries and clean lines, such as bezel trimmed mounts with clipped corners or elegant prong designs that preserve the step facet planes and allow light to enter the pavilion. Because the stone is untreated, it carries the conservation of natural color and structural integrity that advanced collectors and investors prefer, and the very very slightly included clarity assures minimal impact on durability or visual purity. The Natural Gemstone Company offers this piece as a ready to set example of well executed lapidary craft and gemological quality, and it is ideally suited for placement in a curator grade ring, a bespoke pendant, or held as a singular specimen in a focused collection of chrysoberyls and other rare beryls.
