Hey /sci/, I am redoing a half bathroom in my house and I want it to look like you're in a cave. I am already planning a sweet mica wallcovering over dark gray paint, but I want to purchase geodes and stuff to mount on the walls to give you the feeling that you're in a cavern.

Thing is, I don't want to get scammed by some earth children on eBay because I don't know how much these things are really worth. Looking for any resources/suppliers you /sci/entists could recommend. Thanks so much
