Selenite, also known as gypsum, is known for its calming effects as well as its strong use with spiritual work and meditation. Selenite can be used as an aura cleanser and as an energetic blockage healer. It is also useful to put a piece of selenite in each corner of your room(s) to dispel any negative energies lingering around.
Selenite is also a self-cleansing crystal and does not need to be recharged as it absorbs and dissipates negative energy. This makes the crystal useful for charging and cleansing other crystals.
Selenite is associated with the Crown Chakra and the Taurus zodiac sign.
