3.53 Ct. Brownish Green Cabochon Chrysoberyl from Tanzania

This listing presents a single, translucent 3.53 carat oval chrysoberyl, precisely measured at 9.62 by 7.64 by 5.05 millimeters, cut en cabochon to maximize chatoyancy and overall eye appeal. The body color registers as brownish green with intense color saturation, and the stone was graded as very slightly included at eye level. The cabochon profile is oval rather than round, which allows for an elongated, well centered chatoyant band when oriented along the dome axis. The cut is deliberately conservative in dome height to preserve translucency and to allow light to penetrate and interact with internal parallel inclusions while maintaining a pleasing surface curvature. Polish is graded excellent, providing a highly reflective surface that enhances both the luster of the dome and the crispness of the cat s eye band. This specimen is natural and untreated, enhancement none, with documented origin Tanzania, a provenance that is highly regarded among chrysoberyl connoisseurs.

From a lapidary perspective the cutting and finishing decisions are clearly oriented toward maximizing optical phenomena rather than producing faceted fire. The cabochon exhibits a distinct, narrow to medium width, sharply defined chatoyant band that traverses the dome with strong contrast when illuminated. Chatoyancy in chrysoberyl is produced by densely packed, fine, parallel oriented inclusions that act as a single reflecting plane, and in this material the cutter oriented the elongation axis of the oval and the symmetry of the dome to the inclusion orientation to produce a centered, linear band. The dome curvature is uniform, with smooth transitions to the pavilion and a well executed lower profile that preserves overall weight while maintaining good symmetry. The surface shows no abrasive pits or polishing fractures, and the polish quality serves to increase the reflection of incident light, making the band move crisply across the cap as the stone or light source is rotated.

Technically minded buyers will appreciate the intrinsic material properties that make chrysoberyl an exceptional choice for wearable gemstone jewelry. Chrysoberyl has a hardness of approximately 8.5 on the Mohs scale, which confers excellent durability for rings and everyday jewelry, and a specific gravity near 3.73 which contributes to a satisfying heft relative to its dimensions. Refractive indices for chrysoberyl fall in a narrow high range, and the mineral is biaxial with low birefringence, properties which support strong single plane reflections in chatoyant material. The combination of translucency, intense body color and a clean, centralized cat s eye effect means that light is both transmitted and reflected in a manner that emphasizes the band, rather than diffusing it. For setting considerations the stone s 5.05 millimeter height is sufficient to display the optical band without an excessively high profile, lending itself to protective bezel or low claw settings that can both secure the cabochon and allow the band to remain unobstructed.

This chrysoberyl, offered by The Natural Gemstone Company, makes a striking and memorable gift for someone special who values technical excellence and uniqueness. The intense but subtle brownish green body color combined with the precise chatoyant band produces a visual signature that reads as classic yet uncommon, and because the stone is natural with no enhancement and carries Tanzanian origin, it will appeal to collectors and style conscious wearers alike. For a daily wearable presentation we recommend a low bezel or partial gallery that orients the oval axis east west across a finger, enabling the band to read strongly when the hand is relaxed, or a pendant mount with the dome oriented toward the light source to maximize the dynamic banding for social and evening wear. The Natural Gemstone Company guarantees the recording of the stated characteristics and can provide additional detailed imagery and mounting recommendations on request, ensuring that the recipient receives a gemstone that is both technically impressive and emotionally striking.
