0.83 Ct. Chrysoberyl from Tanzania

This transparent yellowish green chrysoberyl offered by The Natural Gemstone Company is a refined example of gemological quality and measured proportions. It weighs 0.83 carat and is fashioned into a round shape with dimensions of 5.56 x 5.57 x 4.08 mm. The cutter employed a mixed brilliant cut to balance fire and brilliance with face up presence, and the result is a compact, well centered stone that displays even pavilion and crown faceting. Coloration is described as medium intense, producing a pleasing yellowish green tone that is evident without appearing overly saturated. The gem is transparent with slight inclusions when evaluated at eye level, and it shows an excellent polish that contributes to crisp facet junctions and optimal light return.

Clarity for this specimen is graded slightly included at eye level, which means inclusions are present but do not materially detract from the stone when examined without magnification. Under routine observation the inclusions are unobtrusive, and they neither interrupt the visual flow of facets nor create significant windowing. The mixed brilliant cut enhances scintillation while retaining a strong center of light, and the cut proportions, measured in the given dimensions, support a well balanced appearance across viewing angles. The excellent polish is notable in the absence of surface abrasions or polishing lines, and facet edges remain clean and sharp. These finishing qualities permit the gemstone to exhibit its inherent optical properties with clarity and refinement.

Durability is a core consideration for practical use, and chrysoberyl performs strongly on the Mohs hardness scale. On the Mohs hardness scale chrysoberyl registers at 8.5, which places it above topaz at 8, and quartz at 7, and just below corundum species such as sapphire which register at 9, and considerably below diamond which registers at 10. This relative hardness confers good resistance to scratching from common materials and household contacts, and it makes chrysoberyl an appropriate choice for daily wear jewelry, including rings and bracelets, when set appropriately. Beyond hardness, toughness and the absence of pronounced cleavage are positive attributes, meaning the stone does not split along well defined planes as some other minerals do. Despite these strengths, chrysoberyl will still be vulnerable to severe impacts and sharp blows, so practical precautions are advised. Setting choices such as a protective bezel or well designed prong system can reduce exposure to knocks, and periodic inspection of the mounting will help preserve the gem over time.

Provenance and treatment status are important to the informed purchaser, and this chrysoberyl originates from Tanzania and is sold with no enhancement. The lack of heat treatment or other enhancements means the color, clarity, and overall character are natural, as extracted from the deposit. The Natural Gemstone Company provides full disclosure regarding origin and treatment status, and this specimen is presented with precise measurements and grading observations to facilitate evaluation and comparison. Routine care consists of gentle cleaning with warm soapy water and a soft brush, avoiding ultrasonic or steam cleaning if inclusions are a concern, and removing jewelry during activities that risk hard impacts. For setting and use recommendations consult with your jeweler regarding bezel proportions or prong protection to match intended wear. The combination of honest description, robust hardness on the Mohs scale, and the absence of enhancements makes this round yellowish green chrysoberyl a technically sound and enduring choice for a range of jewelry applications, and The Natural Gemstone Company stands ready to provide additional technical details and supporting documentation on request.
