The selenite name is mostly synonymous with gypsum, due to it being a transparent variety. It is readily cleaved into natural wands and sheets, which makes it a very soft stone that can be scratched easily. Selenite can be found in Mexico and the United States. Metaphysically, Selenite is believed to be amazing for mental clarity when you are feeling foggy headed.
Each Selenite plate is differently cut but each is clear and beautiful. I enjoy using them for charging my jewelery such as rings and smaller stones. Selenite plates are prized for cleaning and clearing negaitve energy which is why they are often used as "charging plates", in the metaphysical world.
Weight and size varies by specific selenite specimen.
