These selenite crystals are amazing! When I hold them in my hands, there is a "happy"energy that I feel throughout my whole body! These are powerful crystals & I understand how they cleanse other crystals. I love all my crystals. They each have a little different feel to them. I have the Chakra crystals that are so beautifully suspended to hang, right by the chair I sit in, in my living room! I have a serious medical condition & I can't believe it seems to be settling down a bit. Yaaaaaya! Crystals are powerful. If you take care of them using your selenite, research them to understand what crystals might help you the most, & keep in close touch with this company. Read the information they send with tips. And ask questions. Email them & I know they will be glad to help.
