12.37 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing from The Natural Gemstone Company presents one beautiful translucent 12.37 carat oval peach moonstone, with dimensions 16.72 by 13.11 by 7.83 mm, fashioned in a classic cabochon cut. The gem exhibits a medium light peach body color, with a clarity grade of very very slightly included, evaluated at eye level, and an excellent polish that enhances surface smoothness and light return. There has been no enhancement to this stone, the material is entirely natural, and the provenance is Ceylon Sri Lanka, a well regarded source for fine moonstones that produces stones with attractive translucency and even color distribution.

From a gemological perspective this peach moonstone is feldspar based, and its internal structure of intergrown albite and orthoclase lamellae is responsible for the soft sheen and depth that collectors and designers prize. The cabochon shape is the preferred cut to maximize optical effects, producing a gentle floating effect in light when the stone is turned, and the excellent polish ensures that the surface interaction with light is clean and undistorted. The clarity assessment of very very slightly included at eye level indicates that the stone appears visually clean to the unaided eye, while microscopic inspection may reveal fine inclusions typical of natural moonstone, which do not detract from the gem but instead attest to its natural origin. For the educated buyer seeking authenticity and investment quality, the combination of substantial carat weight, attractive translucent appearance, natural unenhanced status, and Sri Lankan origin makes this specimen notable.

Practical considerations for use and long term care are straightforward, the cabochon profile and solid size make this moonstone ideal for a center stone in rings or pendants that allow for protective bezel settings, and the medium light color adapts well to both warm and cool metal choices. Avoid exposure to strong chemicals and extreme heat, clean with gentle soap and a soft cloth, and avoid ultrasonic cleaning to preserve the integrity of the stone.
