To make the most of moonstone's adularescent effect (its rippling light, sparkling surface appearance), it is often cut and set into a shape called a cabochon (a smooth dome).
The main production areas are India and Sri Lanka, but it is also mined in North and South America, Myanmar, and other places.
Moonstone Characteristics
Moonstone is a type of feldspar whose Japanese name is Tsuki-choseki. In Hindu mythology, it is said to have been formed from solidified moonlight, probably because the way moonstone structurally scatters the light that hits it and emits a shimmering glow is reminiscent of the light of the full moon shining through thin clouds.
There are several color variations, some of the more well-known ones being rainbow moonstone, white moonstone, peach moonstone, gray moonstone, and blue moonstone.

The meaning behind moonstone
Moonstone is said to be a stone that symbolizes women and brings love. It is also said to have the power to ward off evil spirits and enhance the ability to predict the future.
It is well known that a woman's bodily rhythms are correlated with the phases of the moon, and it has been said that moonstone's appearance also changes depending on the phases of the moon.
Since both women and the moon are said to have a deep connection with the moon, moonstone has come to be thought of as a symbol of women.
In medieval Europe, there was a custom of lovers giving moonstone to each other to deepen their love, and so it became known as a stone that brings love.
There are also many legends in various regions that believe that the power of moonstone can help you see into the future. In ancient India, there is a legend that a person would receive a message from God containing a moonstone on a full moon night, and in medieval Europe, there was also a legend that looking at a moonstone before going to sleep could help you predict the future.
Because of the meaning behind moonstone, it is believed to have healing powers and to be effective as a talisman to help women with poor health.
