The gemstone selenite is most closely associated with the crown chakra, which represents wisdom and spirituality, as well as the third eye chakra. The colorless beauty and translucency of selenite are often attributed to purity and peace in both metaphysical beliefs and color theory. Selenite is excellent to use when meditating or trying to achieve mental clarity, as it is believed to compel the person holding it to be honest with themselves. Cleanse the body, mind, and spirit of negativity and self-limitation - as well as cleanse your other gemstones being used in healing practices.
