2.92 Ct. Yellowish Green Chrysoberyl from Tanzania

This cushion shaped chrysoberyl presents as a precise, near three carat specimen, weighing 2.92 carats, with dimensions of 8.20 x 7.69 x 5.61 mm, and a length to width ratio of approximately 1.07, indicating a gently rectangular cushion outline. The depth to average diameter ratio is approximately 70.6 percent, a proportion that, combined with the mixed brilliant cut, produces a concentrated light return and a strong visual presence relative to its compact table, while reflecting the material density typical of chrysoberyl, with a specific gravity near 3.73. The mixed brilliant faceting scheme marries a step influenced crown with a brilliant pavilion, conserving color and maximizing scintillation, the medium yellowish green hue remaining even across the field without obvious zoning, the clarity evaluated as eye clean at eyeline inspection, and the overall finish executed to an excellent polish, with no enhancement reported, and an origin from Tanzania that confirms a reputable geological source.

From a technical valuation perspective, the 2.92 carat weight is the primary driver of rarity and premium for this type of chrysoberyl, because chrysoberyl specimens with clean transparency and durable faceting above the three carat threshold are uncommon, and prices typically scale nonlinearly with weight as larger natural crystals suitable for cutting become scarcer. The near three carat mass concentrates value per unit weight, especially given the stone is untreated and eye clean, attributes that collectors and discerning setters prize for a center stone application. The cutter chose a mixed brilliant profile to balance color saturation and brilliance, a deliberate technique that preserves the medium intensity yellowish green while enhancing face up presence, and the excellent polish indicates meticulous lapidary control over facet junctions and symmetry, factors that further reduce light leakage and support higher valuation. The Natural Gemstone Company presents this specimen as a technical grade, investment oriented gem, ready for high quality mounting, with provenance and physical metrics documented for buyers who prioritize measurable attributes in rare colored gemstones.
