20.82 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

If you are searching for a singular center stone to finish an engagement ring, a statement pendant that catches every eye, or a rare specimen to add to a discerning collection, this brown moonstone from Ceylon answers that call. At 20.82 carats it carries presence without shouting, and its translucent body invites a calm and luminous character. Buyers who want a gem that feels intimate and refined rather than overtly flashy will find this stone exactly right, because its warmth and soft internal sheen create a mood that is both timeless and contemporary. Your search for a moonstone that balances substantial size with wearable elegance can end here, with a piece that looks effortlessly sophisticated in every setting.

Let me walk you through the particulars that make this moonstone a truly special selection for collectors and jewelry designers alike. The gem is a round shape, carved as a cabochon to emphasize its gentle internal glow and to present a smooth domed surface that feels elegant against the skin. Its measured dimensions are 15.09 by 14.92 by 12.58 millimeters, proportions that translate to a commanding center of attraction in rings and pendants, and to a comfortable fit when paired with a well designed mounting. The clarity grade is listed as very slightly included when evaluated at eye level, which means the stone reads clean in ordinary wear while retaining natural character. The color intensity is medium, offering a warm brown that is rich without being heavy, and the polish is excellent, so the surface reflects light with a glossy, inviting finish. There has been no enhancement to alter this gem, and its origin is Ceylon Sri Lanka, a source known for producing moonstones with beautiful translucency and consistent quality.

For clients imagining this gem in finished jewelry, consider how different settings will play with its tone and silhouette. Warm metals such as yellow gold or rose gold will amplify the brown warmth and create an antique inspired or romantic aesthetic, while a cooler metal like white gold or platinum will form a modern contrast that highlights the gem as a sculptural element. The cabochon cut and its notable dome height make a bezel setting a particularly smart choice, offering protection and a clean architectural look, though a well crafted prong mount can add lightness and showcase more of the stone for dramatic effect. Because this moonstone is substantial in depth and size it becomes a natural focal point for cocktail rings and signature pendants. For collectors the natural origin and lack of enhancement make it an appealing museum quality example, one that pairs well with minimalist contemporary jewelry or with custom designs that celebrate the gem itself.
