12.38 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This rare 12.38 carat oval brown moonstone measures 17.26 x 13.79 x 7.18 mm, and its cabochon cut showcases a soft, translucent glow that is difficult to find in this color group. Compared with the more common white or gray moonstones on the market, this Ceylon Sri Lanka brown variety offers a distinctive warmth and a medium intense color intensity that reads beautifully in both classic and contemporary settings. Clarity is graded very slightly included at eye level, which means the gem maintains a clean appearance to the naked eye while retaining natural character, unlike many mass produced stones that are heavily treated or assembled from multiple pieces. The polish is excellent, giving a smooth reflective surface that enhances the moonstone effect and elevates the overall presence of the gem. Importantly this piece has no enhancement, a quality that sets it above many commercial alternatives that rely on dyeing, irradiation, or oiling to achieve favorable color and clarity results.

When you compare this moonstone to others available online or in chain retail outlets, the advantages become evident. Larger sizes with good translucency and original untreated color are scarce, and specimens from Ceylon Sri Lanka are particularly sought after for their consistent crystalline structure and attractive tones. This stone balances natural origin, aesthetic appeal, and practical durability, making it ideal for a signature ring, a statement pendant, or a bespoke design where the gem is the centerpiece. The Natural Gemstone Company sources and certifies stones with transparency and integrity, and this moonstone exemplifies our commitment to natural, unenhanced gems with superior craftsmanship in cutting and finishing. For clients who value authenticity and long term value over short term bargains, this brown moonstone represents a superior choice compared with lower grade, treated, or synthetic alternatives. Its size, cut, and polish deliver immediate visual impact, and its natural origin and lack of enhancement provide lasting confidence in provenance and performance.
