The most unique trait of moonstones is something called adularescence - the optical phenomenon that causes the extraordinary glow on their surface. The light moves across the gem, creating the visual effect reminiscent of the full moon shining through a veil of thin clouds - hence the crystal’s name.
This breath-taking gem has always been held in very high esteem in the East. According to Hindu mythology, moonstone was made from moonbeams and could bestow gifts of prophecy and clairvoyance to the wearer.
