The salt was formed by the repeated flooding of seawater millions of years ago. It is the concentrated saline solution combining with the gypsum that promotes the selenite crystal growth in a portion of the salt flats. Selenite is a crystallized form of gypsum. Chemically, it is a hydrous calcium sulfate. Selenite can be used to dispel negativity, both on an emotional and an etheric level. This makes it a good stone for protection. Selenite is a stone of powerful intuition and psychic awareness through its influence on the third eye chakra. Place an order for Spiral Double Pointed Selenite Wand at Natural Agate.
