10.20 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent 10.20 carat oval shape grey moonstone from Ceylon, measuring 13.47 by 9.96 by 9.47 millimeters, cabochon cut, very slightly included at eye level, light color intensity, excellent polish, no enhancement. Its soft grey bodytone and translucent window allow a gentle adularescence to float across the dome, a quality often lost in mass market stones that are either heavily included, overly milky, or treated to simulate sheen. Compared with many commercial moonstones that are small, heavily included, or heat treated to mask flaws, this natural Sri Lankan specimen offers genuine optical play and a clean surface ideal for fine jewellery. The cabochon cut is optimized to show the moonstone effect, while the substantial 10.20 carat weight and oval outline give a modern, wearable scale that outclasses thin slices or poorly proportioned cabochons that lack depth or balance.

Buyers looking for a mid to high end moonstone will find superior value in this gem offered by The Natural Gemstone Company, because it combines rarity of size, untreated provenance, and polished presentation. Other vendors may advertise similar looking stones at lower prices, but those often rely on enhancements, unclear origin, or compromise on cutting standards. This piece is unenhanced, originates from a noted Sri Lankan source, and has an excellent polish that reduces the need for remounting, making it easier and more cost effective to set into a quality ring or pendant. In practical terms the clarity grade very slightly included at eye level means the gem reads clean to most viewers, while its translucency preserves a soft inner glow that complements both white and yellow metals, and pairs well with accent diamonds or colored gemstones. For designers and collectors who prioritize natural optical character, consistent proportions, and straightforward provenance, this 10.20 carat oval grey moonstone represents a step above typical supply, and The Natural Gemstone Company is happy to provide detailed imagery and handling recommendations to ensure it performs beautifully in your finished piece.
