1.71 Ct. Cabochon Chrysoberyl from Ceylon (Sri Lanka)

This piece is a 1.71 carat oval chrysoberyl, presented as a cabochon with dimensions 7.04 by 5.09 by 4.80 millimeters. The cut is a classical oval cabochon, with a high dome and symmetrical outline that preserves the stone mass while optimizing surface curvature and light response. The lab color classification is greenish yellow, with a medium light color intensity that reads as a pale, slightly warm green leaning toward yellow. The gem is translucent rather than transparent, which produces depth without full windowing and yields a soft internal glow when illuminated. The item is certified by Other, with the origin recorded as Ceylon Sri Lanka, and it is offered by The Natural Gemstone Company as a natural, untreated specimen, with no enhancements reported. The polish is graded excellent, and the overall execution indicates careful lapidary control of proportions and surface quality.

From an optical and gemological perspective this chrysoberyl exhibits attributes consistent with classical chrysoberyl family material. The refractive index of chrysoberyl typically falls in the range 1.746 to 1.755, and birefringence is low, on the order of 0.008 to 0.011. Those parameters contribute to a compact, lively appearance when faceted, and in cabochon form they produce a clear, concentrated body color with modest internal sparkle. Hardness on the Mohs scale at approximately 8.5 makes chrysoberyl a durable choice for everyday wear in rings or bracelets, while the medium light tone of this piece affords good versatility for both white and warm metal settings. The greenish yellow designation indicates a primary hue that sits closer to green than pure yellow, with saturation that is balanced rather than vivid, enabling the stone to read as subtle and sophisticated rather than overtly bright.

Clarity is reported as very very slightly included when evaluated at eye level, which in practical terms means minimal visible inclusions under normal viewing distance and lighting. The cabochon cut and translucent character act to mask many internal features, yet some fine internal characteristics may be visible upon close inspection, especially along the girdle or through the dome under oblique light. Typical inclusion types in Sri Lankan chrysoberyl include fine mica or rutile needles, isolated mineral crystals, and healed fissures, and the grading assigned here implies that such features are minor and do not detract from the overall visual integrity. The high dome rising to 4.80 millimeters gives this cabochon significant optical depth and produces the gentle luminous band visible under directional lighting, a phenomenon enhanced by the excellent polish. The lapidary work shows attention to proportion control, with an oval profile that balances length to width to preserve the stone s weight while maximizing the surface area for light interaction.

For application and setting the piece is ideal for designs that emphasize the cabochon s dome and color field. Bezel settings are recommended to protect the high dome and to present the stone as a continuous color surface, and low bezel walls with a fine bezel lip will secure the piece while allowing the dome to dominate the viewing plane. Prong settings can work for less exposed positions but require careful seat forming to avoid stress at the girdle, and in larger daily wear rings a partial bezel or flush mount is a prudent choice. Colour matching with metals should consider the greenish yellow hue, with warm yellow gold bringing out the yellow component and 18 karat white gold or platinum offering a cooler contrast that emphasizes the green tones. For display and photography light sources that combine diffuse and directional components will show both the translucency and the soft luminous band, while incandescent or warm LED lighting will accentuate the yellow bias. As a natural, untreated Sri Lankan chrysoberyl certified by Other and offered by The Natural Gemstone Company this specimen is well suited for collectors and designers seeking a durable, finely executed cabochon with subtle color complexity, and we recommend professional mounting and periodic inspection to maintain the excellent polish and structural integrity.
