Selenite Stick Small. This crystal is a good cleansing item, that is great to be placed in homes and workstations, as it helps to get rid of negative energy, while also promoting clarity and focus. Great to use in mediation, as it aids in creating deep peace. Selenite can touch water, however, it cannot be submerged and left to soak, or else it will damage. Overall, it is good to avoid water all together.
