In Europe, moonstone is considered to be the birthstone for June, although in the United States it shares that distinction with both alexandrite and pearl. Moonstone is also the stone traditionally given in celebration of the 13th anniversary of marriage.
It is easy to see why ancient Hindu mythology believed moonstone was made of solidified moonbeams. In 100 AD, the Romans made jewelry with it and thought it was magically formed out of moonlight. Ancient Greeks linked the stone with the moon deities.
Moonstone comes from the mineral family feldspar, which is one of the most plentiful in the world, however fine gem quality moonstone is very scarce. Its internal structure scatters the light that strikes it, creating a phenomenon known as adularescence. The more shimmer the stone has, the more valuable it is.
This ethereal gemstone has long been regarded to have calming, healing properties.
Because moonstone is a soft stone, it is fragile and can be easily scratched. Moonstone must be handled with care. The best way to clean it is to rub it lightly with a soft polishing cloth.
