Rainbow moonstone is a feldspar that exhibits a blue or multicolored adularescence. The adularescence of rainbow moonstone is caused by the same phenomenon as labradorite (reflection from twinning planes), orthoclase moonstone gets its unusual adularescence from albite inclusions. Some refer to rainbow moonstone as "labradorite moonstone" to distinguish it from orthoclase moonstone.
The Romans admired moonstone and believed that it came from the rays of the moon turned into solid stone on earth. Legends say that moonstone brings good luck. Many believed that you could see the future if you held a moonstone in your mouth during a full moon. Moonstones have been used as jewels for hundreds of years. They were admired by the ancient Romans and Greeks. They were used in Art Nouveau jewelry and later became popular during the hippie movement of the 1960s. We love them today, they are one of our favorite stones!
Deposits of rainbow moonstone are found in Canada, Australia, India, Madagascar, Mexico, Myanmar (Burma), Russia, Sri Lanka (Ceylon) and the USA.
