Selenite:
Also referred to as "liquid light" among crystal users, selenite is a white or clear stone known for its powerful healing and energizing properties. It's actually one of the few crystals believed to be able to cleanse other crystals and is named after the ancient Greek moon goddess Selene, thus associating it with lunar cycles and the divine feminine.
Selenite is said to be a powerful healing crystal that promotes peace and calm, mental clarity, and well-being. It's also believed by some that this crystal can remove negative energy and help you connect to higher realms.
