1.07 Ct. Greenish Yellow Chrysoberyl from Tanzania

This transparent 1.07 carat asscher octagon shape greenish yellow chrysoberyl is presented by The Natural Gemstone Company, a gem of refined proportions and thoughtful cutting, with finished measurements of 5.46 x 5.35 x 4.10 mm. The asscher cut, known for its stepped pavilion and square octagonal outline, has been executed to create strong table facets and concentric light returns, allowing this chrysoberyl to display its medium color intensity with clarity and appeal. Evaluated at eye level the stone is graded slightly included, which means that minor natural inclusions are present but they do not significantly detract from transparency or brilliance when set. The polish is excellent, a mark of careful lapidary work that maximizes surface reflection and yields crisp facet junctions, and there has been no enhancement applied to this gem, preserving its natural state and value. Origin is Tanzania, which is a recognized source for fine chrysoberyl, and the combination of natural, untreated color, accurate proportions, and quality finishing makes this gem a compelling choice for collectors and connoisseurs seeking authenticity and lasting beauty.

From a gemological perspective, several objective attributes explain both the durability and the market appeal of this chrysoberyl, attributes that educated buyers weigh when assessing investment grade gems. Chrysoberyl has a high hardness rating, which confers resistance to daily wear, and a refractive index that produces lively facet reflections, characteristics that are complemented by the asscher cut in this piece. The slightly included clarity grading indicates that inclusions are present but generally unobtrusive to the naked eye, suggesting a gem that retains strong visual impact while remaining natural and unfilled. Medium color intensity in greenish yellow tones places this stone within a subtle spectrum that is both versatile for design and distinct from more common yellow color varieties, and because the stone is untreated, its color is entirely the product of trace elements and crystal chemistry rather than human intervention. For the discerning buyer, factors that enhance value include weight at 1.07 carats, which crosses practical thresholds for many fine jewelry settings, excellent polish which assures enduring beauty, and Tanzanian provenance which often accompanies a documented geological context and reputable sourcing in modern gem trade channels.

The narrative of origin for this chrysoberyl reaches back into deep geological time, a story written in the slow chemistry of the Earth over millions of years. In Tanzania, the gem formed in an environment where beryllium rich fluids interacted with aluminum bearing host rocks under conditions of elevated heat and pressure, likely in pegmatitic or metamorphic settings where concentrated chemical components could crystallize. Over vast spans of time, these fluids migrated through fractures and pockets, allowing chrysoberyl to nucleate and grow into well formed crystals as the local temperature and pressure regimes slowly changed. Trace elements, including small amounts of iron and other transition metals, influenced the final greenish yellow hue, with minute variations in chemical composition and lattice defects producing the medium intensity color we observe today. Subsequent geological processes transported crystals from their primary growth sites into secondary deposits, where careful mining and hand sorting yielded material suitable for precision cutting. The lapidary stage completed the transformation begun deep underground, as a skilled cutter carved the asscher octagon facets to reveal the internal geometry and optical characteristics developed over eons, resulting in the finished gem that is now available from The Natural Gemstone Company, a tangible piece of planetary history and a durable, elegant candidate for fine jewelry.
