6.12 Ct. Cabochon Chrysoberyl from Tanzania

Presented by The Natural Gemstone Company, this piece is a beautiful translucent yellowish green chrysoberyl, weighing 6.12 carats, cut as a round cabochon, with precise dimensions of 8.80 by 8.86 by 7.88 millimeters. The cabochon form has been executed to emphasize the stone character, producing a distinct, sharp cat eye band across the dome that is both centered and well defined. The polish is excellent, contributing to strong luster and a smooth surface that allows the chatoyancy to read clearly even under normal room lighting. The color intensity is described as intense, and the translucent body permits a pleasing depth of tone without appearing overly dark, qualities that are especially desirable in chatoyant chrysoberyl. There has been no enhancement reported, so the material is offered in its natural state, and the overall presentation is one of balanced proportions and visual appeal, suitable for a fine bespoke setting.

From a gemmological perspective, chrysoberyl is a highly desirable species due to its combination of beauty and durability. This specimen exhibits a clarity grade of very slightly included at eye level, which means that inclusions are minor and do not interfere with the aesthetic of the cat eye, and under moderate magnification these features can be seen to consist of oriented fibrous inclusions that are responsible for the single, linear reflection that defines the eye. The hardness of chrysoberyl is approximately 8.5 on the Mohs scale, which makes it suitable for daily wear in secure settings, and its specific gravity and refractive characteristics give it a crisp appearance when properly cut and polished. Origin is Tanzania, a region that has produced notable chrysoberyl specimens and that contributes provenance value for collectors who prioritize documented supply sources. The absence of enhancement increases market appeal for buyers seeking natural, untreated material, and the combination of sharp chatoyancy, intense color, and good clarity places this gem in a favored category for serious purchasers.

For an educated buyer considering this 6.12 carat round cabochon, the factors that drive value are clear. The rarity of an untreated, intensely colored chrysoberyl of this size with a strong, centered cat eye is significant in both the collector and jewelry markets. The technical merits include the precision of the cabochon cut, which maximizes the visual effect, and the excellent polish, which enhances gloss and contrast. From an investment perspective, provenance, treatment status, and documented gemmological details all increase desirability, and this example checks those boxes. Practical considerations include recommendations for secure settings such as a bezel or recessed mount to protect the dome, gentle cleaning with warm soapy water and a soft brush, and professional inspection after any jewelry work. We recommend a third party report from a respected laboratory for buyers seeking formal documentation, and The Natural Gemstone Company can assist with high resolution imagery, additional viewing angles, and facilitation of independent testing upon request, ensuring confidence in purchase and long term enjoyment of this exceptional chrysoberyl.
