18.54 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent 18.54 carat oval shape brown moonstone with dimensions of 15.96 x 13.25 x 10.84 mm, cabochon cut, clarity grade very slightly included evaluated at eye level, intense color intensity, and an excellent polish, enhancement no enhancement, origin Ceylon Sri Lanka. This stone stands apart from the more common smaller and pale moonstones on the market, because its substantial carat weight and rich brown hue create a presence that is both uncommon and elegant. Many moonstones offered online are light washed in color or are heat treated or irradiated to alter tone, while this piece is entirely natural, showing a pure, intense color that retains the intrinsic character of Ceylon gems. The cabochon cut maximizes the stone body and surface sheen, and the excellent polish produces a smooth, reflective finish that elevates its visual appeal compared with rougher, poorly finished cabochons. The clarity grade very slightly included at eye level means that under normal viewing the gem reads clean and lively, outperforming many market examples that show heavier inclusions or cloudy veils.

When you compare this moonstone to alternatives such as smaller commercial stones, synthetic imitations, or treated material, the advantages are clear. The size of 18.54 carats gives jewelry designers freedom to create statement rings and pendants without resorting to assembled pieces, and its oval proportions make it versatile for many mounting styles. The fact that it is natural and untreated enhances its value to collectors who prize origin and authenticity, and the Ceylon provenance is a recognized positive for moonstone connoisseurs. In everyday terms this gem will hold its appeal and resale desirability better than lesser polished or enhanced specimens, it will photograph more attractively for bespoke commissions, and it will sit in settings without the flattened or matte appearance seen in lower grade material. For those seeking a superior natural example with character, size, and integrity, this brown moonstone offers a unique combination of aesthetics and value.
