Shopping around for some gifts and am looking for some stones for a particular individual, and looking at the following Amazon product and checking the reviews I come across this:

My stones are gorgeous, all 36 of them! They arrived promptly, and as shown—a very beautiful variety of shapes and colors. There’s about five of them that aren’t 100% smooth, just as an FYI. I washed them with sea salt to neutralize their energy and I’m keeping them in the window to “charge” them with some solar/lunar energy. I’ll be using my stones for metaphysical/healing purposes.

In all my physics classes I don’t remember anything like this. It must have been covered on a day I skipped class.
