7.16 Ct. Yellowish Green Cabochon Chrysoberyl from Ceylon (Sri Lanka)

This 7.16 carat oval yellowish green chrysoberyl from Ceylon, Sri Lanka, presents a precise lapidary geometry that elevates its optical performance, dimensions 11.71 by 8.52 by 7.10 millimeters. The gem is cut as a high dome cabochon, and the cutter deliberately treated the curved surface as a singular, large geometric plane, optimizing curvature and symmetry to control incident light paths. The translucent body, combined with intense color intensity, produces a saturated yellowish green field that shifts subtly with viewing angle. Clarity is graded very slightly included at eye level, and those inclusions are minor and strategically oriented during preforming to minimize visual disruption while contributing to internal light scattering. The lack of enhancement ensures the color and translucency are wholly natural, and the polished dome returns light in broad bands rather than isolated pinpoint facets, creating a steady internal glow and selective brilliance across the oval axis.

From a craftsmanship perspective, the cabochon exhibits an elevated dome profile and finely tuned outline, executed to engineering tolerances that mimic the benefits of geometric faceting without using multiple facets. The cutter established an ideal dome height relative to the length and width to promote maximum internal reflection, and the smooth polish is finished to an excellent grade that reduces surface scattering and enhances transparency. During orientation the crystallographic axes were considered to align the dominant pleochroic directions with the oval major axis, amplifying color play when the stone is rotated or set in ambient light. The result is a stone that yields strong directional light return and a controlled, lively sheen suitable for bezel or open settings that allow light to enter the crown. For collectors and designers who value technical precision and natural provenance, this specimen from The Natural Gemstone Company offers a combination of measured geometry, disciplined lapidary technique, and undisturbed, intense Ceylon coloration, ready to be set into a piece that will exploit its engineered light performance.
