30.67 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

From the heart of the ancient gem gravels of Ceylon, Sri Lanka comes a story written in stone, a journey that began deep within the island earth and culminates in a single, luminous treasure. Formed over millennia as cooling feldspar veins shifted and layered, this brown moonstone carries with it the quiet, patient work of geological time. Miners working in family run operations and small scale artisanal mines carefully recover these nodules from riverbeds and weathered rock, selecting pieces that promise quality and character. It is this human touch at the origin that sets the tone for every stage of the gemstone journey. The piece you see now started as a raw crystal, its subtle brown tones and translucency hinting at how it would respond to light and to the hand of an experienced cutter. At each step the rough was evaluated, its potential weighed against the respect for natural form that guides ethical sourcing in Sri Lanka. What emerges from that process is not merely a gem, it is a link between the volcanic and sedimentary past of Ceylon and the contemporary world that will wear and celebrate it.

The transformation from rough to polished cabochon is where the gem truly reveals its personality. We present a single, translucent 30.67 carat round brown moonstone, dimensions 20.33 x 20.10 x 10.56 mm, shaped into a classic cabochon to honor the stones natural adularescence and internal glow. The cabochon cut, with its smooth domed surface, amplifies the moonstones innate soft lunar shimmer, allowing a gentle, moving light to sweep across the surface as the gem is turned. Evaluated at eye level the clarity grade is eye clean, a testament to the careful selection of rough and the skill of the lapidary who removed nothing essential and preserved everything beautiful. The color intensity sits at medium intense, a warm brown that reads as earthy and sophisticated, capable of complementing both warm gold and cool silver mountings. The polish is excellent, a mirror like finish that invites touch and holds a soft reflective sheen without any artificial enhancement. There is no enhancement, no heat, no coating, no treatment introduced to alter its natural state. Every measurement, every cut, and every facet of the finish is documented so you know exactly what you own, and so you can set it with confidence into a ring, pendant, or bespoke design.

Beyond the physical attributes, this moonstone carries cultural resonance and the kind of quiet elegance that makes an heirloom. In Sri Lankan lore moonstones have long been associated with the moon, with protection, and with subtle intuition, prized by collectors and jewelers alike for their ability to evoke night light and gentle serenity. This brown variety is particularly appealing for those who favor organic palettes and designs inspired by earth and sky, pairing beautifully with textured metals, natural wood settings, and artisan settings that celebrate asymmetry and hand wrought detail. For the jeweler or collector The Natural Gemstone Company offers this gem as a ready statement piece, or as the nucleus of a commission, complete with provenance that traces back to Ceylon, Sri Lanka. Care is simple, clean with warm soapy water and a soft cloth, avoid sudden temperature change and harsh chemicals, store separately to preserve the excellent polish.

At The Natural Gemstone Company we honor the journey from riverbed to showroom, and this brown moonstone is a perfect expression of that commitment, a single, luminous orb that carries with it the history of its place, the skill of human hands, and the quiet promise of beauty worn close to the heart.
