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

This specimen is a translucent 4.52 carat round yellowish green chrysoberyl, precision formed into a cabochon with dimensions of 8.59 x 8.24 x 6.67 millimeters. The cutting style is a domed cabochon, the dome profile intentionally graded to 6.67 millimeters height to maximize color saturation and light diffusion while maintaining a comfortable setting depth for jewelry. Clarity is graded as very slightly included when evaluated at eye level, inclusions that are minute and typically dispersed beneath the dome so as not to interrupt the surface luster. Color intensity is classified as intense, the yellowish green hue presenting uniform saturation across the table area, and the polish is evaluated as excellent, producing a near mirror finish that enhances the stone volume and the apparent depth of color. There are no enhancements to this gemstone, and its origin is Ceylon Sri Lanka, a locality known for producing chrysoberyl with fine crystalline development and stable, attractive color.

From an optical and gemological perspective this chrysoberyl exhibits characteristics that make the cabochon form particularly appropriate. Chrysoberyl has a refractive index in the range of 1.746 to 1.755 and a specific gravity near 3.70 to 3.78, properties that give it substantial body and a pleasing heft when set. Hardness on the Mohs scale is approximately 8.5, ensuring durability for everyday wear and suitability for rings, pendants, and earrings. The cabochon cutting technique used here emphasizes even color distribution and controlled light transmission rather than faceted brilliance, converting the internal translucency into a soft glow. The dome curvature was calibrated to reduce contrast between the surface and internal planes, limiting the visibility of the very slight inclusions at typical viewing distances. Because dispersion is low, the perceived richness of color derives from absorption characteristics and thickness of the material, not from strong spectral fire, which is consistent with the intense yellowish green body color displayed by this stone.

When considering setting and color interaction with skin tones, the yellowish green chrysoberyl is versatile and responsive to metal choice and design geometry. On fair skin with cool undertones the yellow component will read as a warm accent, and setting in white metals such as platinum or rhodium plated white gold will provide a neutral frame that allows the green aspect to remain crisp, producing a modern, restrained contrast. On fair skin with warm undertones the same stone will harmonize with yellow gold, where the warmth of the metal amplifies the yellow component and results in an integrated, luminous appearance. For olive complexions the balanced yellowish green often appears more green, and pairing with yellow gold or soft rose gold will warm the overall effect while preserving the gem color, a combination that produces elegant continuity between gemstone and skin. On deeper skin tones the intensity and translucency of the cabochon enable the color to read as rich and saturated, and high contrast settings in white metals will make the stone glow while warmer metals will create a more harmonious, embedded look. Practical setting recommendations include a low bezel to protect the girdle and to contain light around the dome, or an open back when the design intention is to allow transmitted light to enhance translucency. A thin halo of small white diamonds or a delicate milgrain bezel can provide optical edges that sharpen the perceived outline of the cabochon without overpowering its intrinsic color.

As representatives of The Natural Gemstone Company we present this 4.52 carat Ceylon chrysoberyl as a ready piece for bespoke jewelry projects, with a professional assessment of its optical behavior and suitability for various mounting strategies. Because the gem is untreated and carries an excellent polish, its performance in different light environments is predictable, and customization options can be specified to favor either reflected surface glow or transmitted color depth. If you intend to set the stone for daily wear, consider a setting that offers edge protection and positions the dome to receive balanced incident light. For presentation pieces intended to emphasize color, consider an open back or thin bezel combined with accent stones that provide complementary cool or warm contrast depending on the desired effect.
