4.18 Ct. Brown Cabochon Moonstone from Ceylon (Sri Lanka)

This translucent brown moonstone, supplied by The Natural Gemstone Company, is a precisely formed oval cabochon weighing 4.18 carats, with dimensions of 11.91 x 9.53 x 5.14 mm. The cutting style is cabochon, featuring a well proportioned domed profile, with the 5.14 mm height representing approximately 43 percent of the length, a ratio that produces a strong visual presence and optimizes depth and light transmission for a warm, consistent body color. The piece exhibits intense color intensity across the surface, a clarity grade of very very slightly included, evaluated at eye level, and an excellent polish that yields a smooth, glass like reflection and comfortable wearability for rings and pendants. Origin is Ceylon Sri Lanka, and the stone has received no enhancement, preserving natural structure and optical behavior for bespoke settings.

From a custom jewelry perspective the oval cabochon geometry and substantive depth make this moonstone highly versatile. The generous dome and secure thickness lend themselves to bezel mountings that protect the girdle and emphasize the lenticular form, while an open back bezel or low profile collet can increase translucency and allow light to interact with the inner structure. The dimensions are ideal for a striking center stone in a cocktail ring, an elegant pendant focal, or a masculine signet style piece, and the oval axis facilitates lengthwise finger orientation for ergonomic comfort. Design pairings with warm metals such as yellow or rose gold will complement the brown tones, while white metals will create a contemporary contrast. The excellent polish ensures minimal surface irregularity, simplifying the setting process and reducing the need for later finishing. For clients seeking a natural, unenhanced cabochon with predictable handling and secure mount options, this Ceylon brown moonstone from The Natural Gemstone Company is a refined, technically sound choice for high quality custom jewelry.
