Greetings @carter1!
@Christina4 shared some the general properties of Selenite in her post:
I’m no crystal expert myself, but from looking at the magickal properties of Selenite, I agree with Phoenix that Selenite can be used to both cleanse and charge other crystals- as well as witchy tools, spaces, the chakras, and so much more!
It’s a really great crystal to have on hand. Enjoy your work with Selenite!
