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

This listing describes one translucent 2.30 carat oval shape yellowish green chrysoberyl, with dimensions 8.00 by 5.89 by 5.44 millimeters, cut as a cabochon. The clarity has been graded as slightly included at eye level, the color intensity is medium, and the polish is excellent. There has been no enhancement, and the stone originates from Ceylon, Sri Lanka. Chrysoberyl is noted for its high hardness, at 8.5 on the Mohs scale, and for its typically adamantine to vitreous luster, characteristics that contribute to durability and surface brilliance in finished gems. In this specimen the cabochon form and translucent body tone emphasize a soft internal glow and a well defined surface reflection, with the slight inclusions adding subtle internal light diffusion rather than obscuring the overall brightness.

The reflective behavior of this cabochon differs from faceted chrysoberyl and from other members of the chrysoberyl family. Faceted chrysoberyl typically returns light in flashes through facet junctions, producing measurable brilliance and scintillation, whereas a cabochon presents continuous specular reflection across its domed surface and a more uniform luminous field. Compared to cat eye chrysoberyl crystals that display a sharp, concentrated chatoyant band when parallel needle inclusions are present, this oval cabochon offers a broader silky sheen and a gentle internal shimmer because the inclusions are light and dispersed. When set against alexandrite examples, which exhibit dramatic color change and strong pleochroism under different light sources, the present yellowish green chrysoberyl maintains consistent hue and reflective character, emphasizing surface polish and translucency rather than color change phenomena. Against other yellow green gem species, chrysoberyl stands out for its denser, more adamantine surface reflection when compared to chalcedony varieties and chrysoprase which are waxier in appearance, and it presents less dispersion than sphene which is known for high fire but lower hardness and a softer surface polish in practical use. Peridot and green tourmaline may show lively facet reflections and stronger pleochroism in faceted forms, but they generally do not match chrysoberyl in surface durability and the concentrated, clean luster produced by a high quality polish.

For practical evaluation and use, this cabochon performs best in settings that show the full oval face, as the domed profile and excellent polish generate a stable reflective plane that reads well under both natural daylight and controlled indoor lighting. In daylight the medium color intensity appears true and even, while warmer incandescent light will deepen the yellow component and cooler LED light may bring a fresher green cast, the reflective quality remaining consistent across lighting conditions. Because the stone is untreated and of Sri Lankan origin, its optical properties are intrinsic to the crystal and not the result of enhancement, which is relevant for conservation and appraisal purposes. Cleanliness preserves reflective performance, therefore routine care with mild detergent and a soft brush is recommended to maintain the mirror like surface. The Natural Gemstone Company provides this description to assist in assessment of optical character and suitability for jewelry applications, with attention to the balance between cabochon presentation, translucency, and the naturally occurring slight inclusions that together define the stone s reflective personality.
