Moonstone has been used as jewelry for centuries, including ancient civilizations. The Romans admired moonstone, as they believed it was born from solidified rays of the moon. Both the Romans and Greeks associated Moonstone with their lunar gods and goddesses. In more recent history, the moonstone became popular during the Art Noveau.
