I didn't ever know that crystals needed to be charged! I first learned of something similar when the company where I purchase salt offered a crystal water kit and the directions said to leave the stones outside for 24 hours every month. Crystal connoisseurs have since taught me that selenite can be used to charge other crystals and even jewelry and gemstones! #whoknew! Now I keep a selenite bar to hold my jewelry each night! It looks so pretty and offers an organized place for keeping just a few meaningful and purposeful belongings! Many consider selenite to be a must-have crystal in the house for good luck, protection, purity and cleansing the air where it is placed while calming and soothing people who come into contact with it. It may also bring deep peace and tranquility.
