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.
Moonstone is a crystal of many myths and legends. One famous legend from Vedic history talks about the battle between Vishnu and Bali, the demon god. When Vishnu broke Bali’s body into pieces, the parts that fell on Earth turned into different jewels. The sparkle in his eyes became “Chandrakanta" or what we now call moonstones.
