8.03 Ct. Chrysoberyl from Tanzania

This transparent chrysoberyl presents as an 8.03 carat cushion shaped gem, with precise dimensions of 10.77 x 10.47 x 8.02 mm, and a mixed brilliant cut that balances scintillation with depth of color. The body tone is a yellowish green with medium color intensity, a range that offers visual presence without overpowering versatility for jewelry design. Clarity was evaluated at eye level as very very slightly included, indicating that any internal characteristics are minimal and do not materially affect the gem s apparent transparency or light performance to the unaided eye. The polish is excellent across the table and pavilion facets, producing clean facet junctions and consistent light return. There is no enhancement, which means the color and clarity are entirely natural and stable, and the stone has not been subjected to heating, filling, or other treatments that could alter its appearance in the short or long term.

The gemstone s species conveys practical value as well as aesthetic appeal. Chrysoberyl is a durable mineral, with a Mohs hardness of approximately 8.5 and strong chemical and structural stability, making it well suited for everyday wear in rings and other jewelry that receive regular exposure. The mixed brilliant cut employed here optimizes both face up brilliance and depth, allowing the stone to exhibit lively flash from the crown while preserving saturation through the pavilion. At the stated dimensions and carat weight, this cushion form sits comfortably in a substantial ring setting or as a focal stone in a pendant, where it will read as a significant and refined center gem. The balanced proportions and expert cutting contribute to even light distribution, minimizing windowing and ensuring the yellowish green tone reads uniformly across a variety of lighting conditions.

Provenance from Tanzania adds a distinct layer of value to this chrysoberyl, beyond the measurable parameters of weight, cut, clarity, and color. Tanzanian deposits, including well documented occurrences in the southern regions, are recognized for producing chrysoberyl with clear, well saturated hues and consistent crystallographic quality. Origin information matters to collectors and connoisseurs because it speaks to the geological conditions that produced the stone, the likelihood of consistent performance, and the rarity profile relative to other sources. In the case of Tanzanian chrysoberyl, trace elemental chemistry and the specific formation environment yield stones that frequently exhibit the appealing yellowish green family of colors, and stones with clean, transparent material and natural color are increasingly sought after. The absence of enhancement, combined with documented Tanzanian origin, supports a transparent provenance narrative that enhances market confidence, collector interest, and long term desirability.

At The Natural Gemstone Company we describe this specimen with measured accuracy and provide practical guidance for use and care. For setting, consider prong or bezel styles that both display the stone s mixed brilliant cutting and provide protection to the girdle and corners of the cushion shape. Given the species hardness and polish quality, normal jewelry manufacturing techniques are suitable, and finished pieces are durable for regular wear. For routine maintenance, cleaning with warm soapy water and a soft brush is recommended, avoiding harsh chemicals and abrupt thermal shock. If certification or additional documentation is required, our company can supply supporting reports, high resolution imagery, and any provenance records available for this gem. This combination of natural color, transparent clarity, excellent polish, documented Tanzanian origin, and lack of enhancements defines the stone s appeal for both collectors and discerning jewelry clients, offering a refined balance of beauty, durability, and provenance.
