0.87 Ct. Cabochon Chrysoberyl from Ceylon (Sri Lanka)

One piece description from The Natural Gemstone Company, one transparent chrysoberyl, weight 0.87 carat, oval outline rendered as a cabochon, dimensions 5.81 x 4.99 x 3.17 mm, origin Ceylon Sri Lanka, enhancement none. This specimen presents a medium intense brown body color that sits comfortably between honey and olive brown, with even color distribution across the dome. The cabochon form has been chosen to emphasize the stone transparency and the subtle interplay of internal structure and surface reflection, giving the gem presence in small scale settings. The absence of heat or any other enhancement preserves the natural crystal lattice and optical behavior characteristic of Sri Lankan chrysoberyl, a provenance that is well regarded by connoisseurs for producing clean material with appealing tonal nuances.

Cut and finishing notes for this oval cabochon focus on proportional symmetry and polish quality, the dome height of 3.17 mm relative to the length and width provides a pronounced but balanced crown, enabling controlled light return while maintaining wearability in standard ring or pendant mounts. The cutter has maintained a consistent curvature along both longitudinal and transverse axes, resulting in an even line of sight without noticeable offset or keel. The polish is evaluated as excellent, producing crisp specular highlights and smooth surface continuity, factors that enhance perceived transparency and saturation. Under directional illumination the dome reveals a narrow linear reflection across the crown, indicative of oriented needle like inclusions or fibrous growth that interact with incident light. This linear feature is subtle and controlled by the cabochon profile, and in appropriate settings will provide a refined visual accent without dominating the stone appearance.

Clarity is graded as very slightly included at eye level, a practical evaluation standard for hand held inspection, meaning that the stone remains transparent with only minor internal features visible without magnification. These inclusions do not interrupt the overall light transmission, and they can contribute to character when judged against the gem hardness and durability typical of chrysoberyl. From a gemological standpoint chrysoberyl is a robust species, hardness approximately 8.5 on the Mohs scale, specific gravity approximately 3.71 to 3.78, refractive index in the range 1.746 to 1.755 and birefringence on the order of 0.008 to 0.010. Dispersion is low, therefore the gem reads as a solid color field rather than a fire oriented gem. Pleochroism in chrysoberyl is generally weak, and the cabochon presentation here minimizes directional color shifts, producing a consistent medium intense tone that is well suited to classic jewelry palettes.

For designers and end users the combination of small size and high polish makes this cabochon versatile. Recommended mounting approaches include low bezel work to protect the dome edge, or flush settings where the dome is slightly raised for optimal light interaction, always aligning the long axis of the oval with the principal axis of the piece to emphasize symmetry and any subtle linear chatoyancy. Given the natural, unenhanced origin, The Natural Gemstone Company can provide provenance documentation on request, and we advise standard gem care practices including avoiding sharp blows and prolonged exposure to harsh chemicals, cleaning with warm soapy water and a soft brush as appropriate. This 0.87 carat Ceylon chrysoberyl cabochon is suited to collectors who value naturally sourced stones with meticulous cutting and finishing, and to jewelers seeking a compact, durable gem with refined optical personality.
