13.86 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One, translucent yellow moonstone weighing 13.86 carat, presents as an oval cabochon with precise dimensions of 14.63 x 12.51 x 10.13 mm, offering a substantial presence suitable for a variety of jewelry applications. The gem is cut as a smooth cabochon, a form chosen to best display the characteristic optical effects of moonstone, while the oval outline provides classical symmetry for ring, pendant, or brooch settings. Clarity is graded as very very slightly included, evaluated at eye level, which denotes minimal internal features that are visible only upon close inspection and do not detract from the overall uniformity and translucency of the material. Color intensity is described as very light, producing a soft yellow tone that reads as elegant and understated, and the surface exhibits an excellent polish that enhances luster and touch. The origin of this moonstone is Ceylon, Sri Lanka, and the gem is presented in natural, untreated condition with no enhancement.

Optical character is a focal attribute for this moonstone, with translucency that allows for an even, diffused internal glow rather than sharp transparency, producing a gentle optical sheen when viewed in directional light. The cabochon profile, combined with the internal structure typical of sodium potassium feldspar, facilitates the adularescent effect associated with fine moonstones, which appears as a subtle, moonlike shimmer that moves beneath the surface as the stone or the light source shifts. The very very slightly included clarity grade implies that inclusions are scarce and generally fine, which supports an uninterrupted play of light across the dome. Color distribution is consistent across the table and crown, and the very light yellow tone interacts with warm metal alloys to produce a complementary, muted palette, while still maintaining enough presence to stand on its own in a minimalist setting.

From a technical perspective, the dimensions and depth of 10.13 mm indicate a relatively high cabochon, which should be taken into account during setting design, as the profile will require a secure, protective mounting. A bezel setting is recommended for daily wear pieces, as it offers continuous protection around the stone perimeter and secures the cabochon without obscuring the visible face. For pendants and brooches, the substantial carat weight and profile make this moonstone ideal for a central showcase component, whereas for rings the depth and cabochon height mean that the stone will sit prominently above the mounting, so a low profile bezel or a partially recessed seat should be considered if wearer comfort and snag resistance are priorities. As a feldspar mineral, moonstone has a Mohs hardness of approximately six to six and a half, so practical care considerations include avoiding hard knocks, abrasive surfaces, and exposure to harsh chemicals. Cleaning by warm, soapy water and a soft cloth is effective and safe, and mechanical cleaners, steam, or ultrasonic methods are not recommended for routine maintenance.

Provenance, treatment disclosure, and suitability for collection or bespoke pieces are important for both designers and clients, and this moonstone is supplied with an explicit statement of no enhancements, confirming that color, clarity, and optical properties are natural and intrinsic. The Sri Lankan origin contributes to its trade documentation and is consistent with reputable sources for gem quality moonstones, and further certification or independent gemological assessment can be provided upon request for insurance or appraisal purposes.
