2.66 Ct. Cabochon Chrysoberyl from Ceylon (Sri Lanka)

This 2.66 carat round brownish green chrysoberyl from Ceylon is presented as a precisely shaped cabochon, measuring 7.54 x 7.43 x 5.49 millimeters, and is offered by The Natural Gemstone Company. The cutting approach emphasizes a high, well centered dome with a smooth, continuous curvature to maximize the stone's semi translucent transmission and surface luster. The cabochon profile is engineered to bring forward the medium intense brownish green body color while allowing any internal silk or oriented inclusions to manifest as subtle optical textures, without compromising the eye clean clarity grade assigned at normal viewing distances. The polish is excellent, exhibiting a near mirror finish with no visible polishing lines or surface abrasion, which enhances light return and surface brilliance characteristic of fine chrysoberyl cabochons.

From a gemological perspective this specimen is representative of chrysoberyl in its crystallographic and physical properties, with an expected refractive index range near 1.745 to 1.755 and a specific gravity in the mid 3.70s, and a Mohs hardness around 8.5 that confers notable wear resistance for everyday jewelry. The medium intense brownish green hue is uniform across the dome, with modest translucency that produces depth without significant light leakage, making the piece ideal for bezel or closed back settings where color saturation and surface presentation are paramount. The absence of enhancement verifies that the color and clarity are natural, and the eye clean assessment indicates inclusions, if any, are microscopic or oriented so as not to interrupt the visual plane at normal viewing. Crafting recommendations include orienting the stone so the dome faces the primary light source to optimize perceived saturation and any subtle banding, and selecting a setting that protects the edge and girdle to preserve the polished surface. This Chrysoberyl cabochon from Sri Lanka combines natural provenance, careful lapidary control, and stable material properties, offering a technically refined option for connoisseurs seeking a robust, characterful gemstone for precision jewelry applications.
