Popular with the Romans, who thought it was formed out of moonlight, and in India, where it is considered a sacred zodiac gem, Moonstone is one of the most coveted varieties of Feldspar.



In antiquity, men used Moonstone to predict the future by placing them in their mouths.

A symbol of the 3rd eye, Moonstone was once believed to balance yin/yang, protect against epilepsy and sun stroke, cure headaches and nose bleeds, and ensure a high yield in crops. Today, crystal healers believe that it can help men open their feminine emotional aspects.

Moonstone is a highly prized gift for lovers as it is believed to arouse tender passion. In some cultures, it is also believed to accentuate the wearer's nature, whether positive or negative.



Moonstone is a member of the Feldspar group of minerals and is closely related to Sunstone. The name Feldspar comes from the German “feldt spat”, meaning “field stone”. This is because when Feldspar weathers, it releases large amounts of plant nutrients, such as potassium, which enrich the soil.

Moonstone's characteristic shimmer or sheen is also known as “schiller” or “aventurescence” and is caused by the intergrowth of two different types of Feldspar with different refractive indexes. Moonstones are often cut as cabochons to maximize this effect.

Traditionally, Moonstone has a silver to blue sheen, near perfect clarity and a colorless body color. Sri Lankan Rainbow Moonstone possesses all these qualities and as it is quite rare and becoming rarer, it is definitely a “must have” for any jewelry collection. Sri Lankan Rainbow Moonstone is laboriously chipped directly from a host deposit in Meetiyaguda, Sri Lanka. Interestingly, Sri Lankan Rainbow Moonstone typically displays such a stunning transparent clarity (not usually associated with this gemstone), intense bright blue shimmer and dazzling play of color that it can be cut as a faceted gemstone. This is truly unique and further accentuates the desirability of this highly collectable exotic gemstone.
