Moonstone is a fine gemstone belonging to the silicate group and the feldspar family of minerals. Jean Claude Delamétherie discovered this stone in 1801.

The moonstone is characterized by the adularescence :  an optical phenomenum constiting in “a milky, bluish luster or glow originating from below the surface of the gemstone.” The moonstone is colorless or opalescent white.

This fine gemstone is mainly found in Sri Lanka, in Asia (Burma and India), in America (Brazil, United States), in Africa (Tanzania) and in Australia.
