0.43 Ct. Chrysoberyl from Ceylon (Sri Lanka)

This specimen is a transparent 0.43 carat chrysoberyl, cut in an emerald shape, with dimensions of 4.80 x 3.82 x 2.32 millimeters. The body color is a yellowish green with medium light intensity, presenting a stable and even tone across the table and pavilion. Clarity has been evaluated at eye level and graded as slightly included, with small natural internal features that do not materially disrupt the overall transparency. The cut exhibits an excellent polish, and no enhancements have been applied. Origin is Ceylon Sri Lanka, a locality well regarded for producing chrysoberyl with clean crystal habits and durable optical properties. The Natural Gemstone Company presents this gem as a well proportioned, naturally sourced example, documented for its physical measurements and treatment status.

The geometry of the emerald cut in this chrysoberyl is responsible for its distinctive light performance, and the faceting scheme has been executed to maximize the interaction between incident light and the internal planes of the crystal. An emerald cut employs broad step facets on both the crown and the pavilion, producing a sequence of parallel planes that act as reflective channels. The large rectangular table facilitates straightforward viewing into the stone, while the elongated step facets along the crown create controlled flashes of light rather than the scintillation typical of brilliant cuts. This results in a clear, architectural play of light, characterized by broad flashes and linear reflections that emphasize color and clarity. Given the gem dimensions and a depth proportion of approximately 54 percent, light entering the table is efficiently redirected by the pavilion steps, producing parallel bands of reflected light that accentuate the yellowish green hue without dispersing it into large spectral flashes. The polished facet junctions and precise facet alignments reduce stray light leakage, preserving contrast and allowing the eye to perceive subtle variations in tone and internal texture that are characteristic of natural chrysoberyl.

In practical terms the emerald cut geometry enhances the gem for settings that benefit from visual order and optical stability. The rectangular outline and step facet structure lend themselves to bezel settings or four prong mounts that secure the corners while maintaining a broad table for inspection. The slight inclusions are positioned so they are not dominant when set in typical ring or pendant orientations, and the excellent polish minimizes surface disturbances that might otherwise interrupt the linear light returns. Because no enhancements have been applied, the stone communicates its natural formation history through its color saturation and internal character, and its Ceylon provenance provides context for its crystalline quality. For cataloguing and appraisal purposes The Natural Gemstone Company records the full set of measurements, weight, clarity grade, color intensity, polish, treatment status, and origin, enabling transparent comparison with similar chrysoberyl examples. This emerald cut chrysoberyl is suitable for collectors and designers who prefer a geometry that emphasizes structural light play, measured color expression, and honest, documented gem attributes.
