The selenite name is mostly synonymous with gypsum, due to it being a transparent variety. It is readily cleaved into natural wands & sheets, which makes it a very soft stone that can be scratched easily. Found in Mexico and the U.S.
I personally love these pieces because they fit so comfartably in the palm of your hand or even over your eyes. They are just such a soothing stone to be around.
Metaphysically, these pieces are amazing for mental clarity when you are feeling foggy headed. Selenite helps you stay true to yourself & to your word as well. It is also known as a guidance stone for those who need a little extra help finding their way through life.
