1.76 Ct. Greenish Yellow Chrysoberyl from Tanzania

This 1.76 carat transparent chrysoberyl from Tanzania presented by The Natural Gemstone Company is a finely proportioned asscher cut in an octagon outline. Its measured dimensions are 6.34, 5.95, 5.23 millimeters, producing a substantial face up for its carat weight while retaining a compact profile suitable for bespoke rings and pendants. The stone exhibits a greenish yellow hue with medium color intensity, and it is offered with no enhancement, ensuring that the color and clarity are entirely natural. Clarity is graded as slightly included evaluated at eye level, which means that the stone displays minor internal characteristics that are visible to a careful unaided inspection but do not compromise its overall transparency or visual appeal. The exceptional polish applied to every facet yields crisp facet junctions and mirror like facet surfaces, enhancing both the cut geometry and the inherent optical properties of chrysoberyl.

The asscher style faceting used on this octagonal stone emphasizes step cut architecture, featuring concentric parallel facets on the crown and pavilion that create a hall of mirrors effect. The asscher interpretation on this specimen favors large, square oriented crown facets converging toward a neatly centered table, and graduated pavilion steps that return light in broad flash planes rather than scintillation points. The precise symmetry of the octagon perimeter and the well aligned facet meeting points produce uniform light return across the table and shoulders. With a pavilion depth relative to the average of length and width of approximately eighty five percent, this cut is deeper than many modern brilliant style cuts, which accentuates color saturation and yields a controlled, layered internal reflection pattern. The excellent polish ensures minimal surface diffusion of light, so the step facets read clean and the internal reflections remain defined under varied lighting.

Color characteristics of this Tanzanian chrysoberyl warrant close attention, because the greenish yellow tone sits within the desirable spectrum for chrysoberyl that balances freshness with warmth. The medium intensity provides enough saturation to be distinctly colored in daylight and artificial light, while remaining adaptable to a variety of metal tones and jewelry designs. The coloration in chrysoberyl is influenced by trace transition elements, commonly iron, which in controlled concentrations produces yellow to greenish yellow tones without the instability associated with many treated gems. Because this stone is untreated, its hue is stable over time and under typical wear conditions. Observationally the stone displays subtle orientation dependent color shifts, so that face up it reads as a lively greenish yellow, while slight rotations or changes in lighting angle reveal nuanced adjustments in tone that add depth to the visual experience.

The clarity grade slightly included evaluated at eye level indicates that the internal features are intrinsic to this natural chrysoberyl and contribute to its character rather than detract from it. Under magnification small crystals and faint growth related features are present within the step facets, and at certain viewing angles these elements interact with the deeper pavilion to create depth and interest. Importantly these inclusions do not interrupt facet symmetry or produce windowing that would diminish face up color or luster. Chrysoberyl is a durable species with a Mohs hardness of approximately eight and a half, offering superior resistance to abrasion and suitability for daily wear in rings and bracelets. Coupled with the excellent polish and the absence of any enhancement, this material promises long term stability, retaining its optical performance through routine use and periodic professional cleaning.

As a piece destined to captivate for years, this Tanzanian asscher chrysoberyl combines enduring material properties with considered cutting and finishing. The step cut architecture will age gracefully, preserving strong planar reflections and a dignified, architectural appearance that contrasts with more fleeting brilliance of mixed cuts. The natural medium greenish yellow color will remain stable because there is no heat treatment or dyeing, and the stone s provenance from Tanzania is documented as part of The Natural Gemstone Company s commitment to traceability and quality. For setting recommendations the asscher octagon performs exceptionally well in four prong or partial bezel designs that protect the corners while allowing the table and step facets to present prominently. Care is straightforward, using warm soapy water and a soft brush to maintain the polish, avoiding harsh chemicals and extreme thermal shock. This chrysoberyl is a technical and aesthetic statement, a naturally fashioned gem that will continue to draw the eye and reward close inspection for decades to come.
