8.24 Ct. Cabochon Chrysoberyl from Ceylon (Sri Lanka)

One translucent green chrysoberyl, weighing 8.24 carats, is presented in an oval cabochon form, with precise dimensions of 11.68 by 8.67 by 8.23 millimeters. The piece exhibits a medium color intensity, a clear green hue with subtle yellowish undertones visible in different lighting conditions, and a uniform tone across the dome. Cut as a cabochon, the stone displays a smooth, well proportioned dome and a sharply defined chatoyant band that traverses the surface, consistent with fine chrysoberyl cymophane, commonly referred to as cat eye. The polish on the dome and girdle areas is excellent, producing a high luster and a clean, uninterrupted reflection, while the translucency allows light to pass through sufficiently to reveal internal silk and oriented inclusions that generate the distinctive eye, without compromising the gem s overall visual clarity. The specimen is natural, with no enhancement, and is sourced from Ceylon Sri Lanka, an origin noted for producing chrysoberyl with particularly attractive color and chatoyancy.

From a gemological perspective, this chrysoberyl combines important attributes that affect both aesthetic appeal and practical wearability. Chrysoberyl rates 8.5 on the Mohs scale of hardness, providing strong resistance to scratching and making it a suitable choice for daily wear pieces when set with appropriate protection. The cabochon cut and the internal oriented inclusions are the principal factors responsible for the single, well focused band of reflected light, a characteristic highly regarded in chatoyant stones. The moderate saturation of the green color is balanced by the stone s inherent translucency, which allows the chatoyant band to remain visible under a variety of light sources. The absence of any heat treatment or dye, confirmed through standard gemological observation, preserves the integrity of the material, and contributes positively to long term value and collector interest. Measurements are provided to assist in planning a setting, and the weight of 8.24 carats represents a significant size for natural chrysoberyl, particularly for an untreated, eye exhibiting example from Sri Lanka.

Care, use, and documentation recommendations are provided to ensure the stone s condition is maintained and its provenance and attributes are clearly recorded. Routine cleaning with warm water, a mild detergent, and a soft brush is appropriate, followed by gentle drying with a soft cloth, avoiding prolonged exposure to strong acids or solvents. Ultrasonic cleaning is generally acceptable for well secured cabochons, however mechanical impact should be avoided to protect the dome and to prevent loosening in the setting. For jewelry planning, settings that protect the girdle and bezel the stone to reduce exposure to knocks are advisable, especially in rings intended for frequent wear. The Natural Gemstone Company provides detailed images, measurements, and origin information with each item, and can supply additional certification or independent gemological testing on request, to support appraisal and insurance needs. The information above is presented to assist in evaluation and selection, and further technical details or high resolution imagery can be provided upon request.
