21.93 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent 21.93 carat oval grey moonstone, dimensions 17.82 by 13.62 by 11.65 mm, cabochon cut with a well centered domed apex, clarity grade very very slightly included evaluated at eye level, medium color intensity, excellent polish, no enhancement, origin Ceylon Sri Lanka. The cabochon has been shaped to maximize adularescence, with a convex dome that preserves internal layering and promotes interference of light between orthoclase and albite lamellae, producing a soft silver beige to blue sheen against the grey body color. Clarity observations recorded at 10 centimeter viewing distance indicate only minimal pinpoint and fine feather inclusions that do not detract from the overall translucency, and that contribute to a subtle internal texture without compromising structural integrity. The polish is of the highest standard, with uniform surface reflectivity and negligible polish lines, enabling crisp light return and minimizing surface pits or abrasion that could scatter light and flatten the schiller effect.

From a lapidary and setting perspective the piece offers practical proportions and a robust profile for secure mounting, the oval outline at 17.82 by 13.62 mm paired with an 11.65 mm depth yields a substantial crown height that enhances visual depth and adularescent mobility when the stone is rotated under light. The weight and dimensions make this specimen particularly well suited for a statement ring or a center pendant where the dome can be presented face up, a low to medium bezel setting being recommended to protect the girdle and to preserve the cabochon silhouette. As supplied by The Natural Gemstone Company this moonstone is natural and untreated, providing provenance from Ceylon Sri Lanka that is consistent with classic feldspar specimens from that region, and offering collectors and designers a material with authentic microstructure and stable optical behavior. For care avoid prolonged exposure to ultrasonic cleaning and high heat, clean with mild soapy water and a soft brush, and consult your jeweler for appropriate mounting techniques to retain the integrity of the cabochon and to showcase its adularescent properties.
