2.67 Ct. Green Chrysoberyl from Tanzania

This transparent green chrysoberyl presents with a precise weight of 2.67 carats, an oval outline, and measured dimensions of 8.53 by 7.05 by 5.67 millimeters. The gem has been fashioned with a mixed brilliant cut, combining a faceted brilliant crown articulation with a stepped or modified pavilion design, and it displays a light green hue with light color intensity. Clarity has been evaluated at eye level as slightly included, and the piece benefits from an excellent polish that maximizes facet definition and light return. There has been no enhancement, and the provenance is Tanzania, information that The Natural Gemstone Company records and verifies as part of our standard documentation process.

From a cutting and optical performance perspective the mixed brilliant architecture on this oval chrysoberyl is engineered to balance scintillation and body color. The crown is cut with well proportioned star and kite facets that focus light into a crisp scintillation pattern across the table, while the pavilion mechanics rely on step like facets to control internal reflection and color dispersion. Based on the given dimensions the depth profile works out to an approximate depth of 5.67 millimeters against an average of the length and width of 7.79 millimeters, which translates to a depth proportion of roughly 73 percent. This depth percentage is moderately deep for an oval mixed brilliant chrysoberyl, and it enhances the perceived saturation of the light green tone by concentrating optical path length, while slightly reducing face up spread when compared to a shallower cut of equal carat weight.

Weight is a primary determinant of rarity and market value in chrysoberyl, and this 2.67 carat example occupies a notable position on the size distribution curve for gem quality green chrysoberyl from East Africa. Chrysoberyl crystals of gem clarity and attractive color are uncommon in sizes above two carats, and each incremental carat yields a disproportionately larger impact on both rarity and price. The 2.67 carat weight therefore elevates this stone beyond more common smaller sizes, offering collectors and designers a more substantial visual presence as well as improved market liquidity. In practical gemological terms the heavier mass also offers advantages in cutting, allowing the cutter to retain more carat weight while achieving an efficient facet architecture, which in turn yields stronger light performance and greater durability for use in rings and other frequently worn jewelry.

The slightly included clarity grade evaluated at eye level signals the presence of small internal features that are visible under close inspection but do not materially compromise the integrity of the stone. Typical inclusion morphologies in chrysoberyl include minute crystals, thin needles, and isolated feathers, and in this specimen the cutter has oriented facets to minimize inclusion visibility through the table and maximize brilliance. The excellent polish further mitigates the optical impact of inclusions by providing crisp facet junctions and smooth reflective planes, which reduce light scatter and preserve contrast. For connoisseurs who assess both aesthetic and structural factors, the combination of 2.67 carats, transparent body, and controlled inclusion visibility makes this gem an attractive candidate for fine jewelry where both appearance and long term performance are priorities.

For jewelry application and specification The Natural Gemstone Company recommends settings that exploit the gem weight and optical characteristics of this oval chrysoberyl. A low profile four or six prong rub over setting will allow maximum table exposure to showcase the mixed brilliant scintillation, while a partial bezel or halo mount can protect the girdle and capitalize on the slightly deeper pavilion to deliver added face up presence. Designers may choose to orient the longer axis vertically for rings to complement finger proportions, and the measured dimensions facilitate predictable setting designs without excessive re cutting. Because there is no enhancement recorded, the stone carries premium appeal for clients seeking natural, untreated material, and our team stands ready to provide additional lapidary reports, high resolution imaging, and mounting recommendations to ensure the final piece preserves the gemological qualities that define this rare 2.67 carat Tanzanian chrysoberyl.
