Moonstone is an Orthoclase Feldspar, formed from cooling magmas deep within the Earth As the magmas cooled at differing speeds so thin layers of the minerals Albite and Orthoclase formed . As these minerals have different reflective indexes , light entering the stone is scattered and diffused in many directions, creating the wonderful changes in colour, known as adularescence.
Moonstone may be white , blue or pink in colour .
Hindus and Roman myths suggested that moonbeams were captured and frozen in Moonstones, hence its magical appearance. It was worn as an amulet worn by ancient travellers . The Ancient Greeks suggested that two people wearing Moonstones would fall in love on the night of a full moon !
