Moonstone Its name comes from Latin "petra luna". It is the stone of the moon goddesses Diana, Isis and Selene. It has a milky and translucent appearance, and shows a lightly nacred reflection, called adularescence, which is caused by the presence of albite impurities. It is a mineral from the Feldspar group. It was discovered in the alpine zone of Adula (Switzerland, Italy). It is highly regarded in amulets and talismans. It can help foresee the upcoming, attracts good luck, and it can change its adularescence depending on the energy it receives.
