Selenite is a wonderful crystal as it is self-cleansing, on top of sending out cleansing energies to its general vicinity. For this reason, some witches will use slabs of selenite to cleanse their other crystals, particularly those that are sensitive to other cleansing methods (i.e. water, sunlight).
Selenite is a shiny, milky white crystal.
In regards to the chakras, selenite works well with the crown chakra.
Around the home, selenite promotes a loving environment and connection with the mystical. It also has benefits when used during meditation and when contacting your spirit guides, and is great for elevating inner peace and clarity.
I personally have both a selenite slab for cleansing small crystals and jewellery, as well as a selenite tower in a homemade cleansing station to cleanse other larger crystals.
