13.45 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

The Natural Gemstone Company presents one translucent white moonstone weighing 13.45 carats, an oval shaped gem with precise dimensions of 15.89 x 14.22 x 8.80 mm. The stone is fashioned as a cabochon, a profile and finish chosen to enhance the internal light phenomena typical of moonstone. Origin is Ceylon Sri Lanka, a source long regarded for producing clean, attractive specimens of this feldspar group mineral. The gem is colorless in body tone, with a clarity grade of very slightly included when evaluated at eye level, and it exhibits an excellent polish across the well formed dome and girdle.

Visually the cabochon presents a soft internal sheen consistent with classic adularescence, a characteristic scattering of light that appears to glide across the dome as viewing angle or illumination changes. The material is translucent, allowing a degree of light transmission while maintaining that milky, ethereal quality associated with white moonstone. Included features are minor and consistent with the stated very slightly included clarity grade, appearing as small internal pinpoint and feather like features that do not interrupt the gem's overall visual appeal or its light play. The excellent polish supports a smooth, reflective surface that accentuates the adularescent band and lends a refined finish suitable for fine jewelry.

From a gemological and practical perspective this moonstone is an unenhanced natural specimen, free from heat or chemical treatments, and retains its natural surface and internal characteristics. Moonstone is a member of the feldspar family and typically records a Mohs hardness in the range of six to six and a half, which makes careful setting and wear considerations advisable. For secure everyday use a bezel setting or protective mount is recommended, particularly for rings, whereas pendants and earrings can showcase the cabochon profile more openly. Routine care should involve gentle cleaning with a soft cloth and mild soapy water, avoiding ultrasonic bathers, steam cleaners, and harsh chemicals, and storing the stone separately from harder gems to prevent abrasion.

The Natural Gemstone Company can supply further documentation and detailed imagery on request, including additional angles under controlled lighting to show the adularescence and any internal features more clearly. The combination of a substantial 13.45 carat weight, precise oval dimensions, a high quality cabochon cut, colorless body tone, and Ceylon provenance places this moonstone as a refined and collectible material for design oriented pieces where the subtle play of light is the central aesthetic.
