Ciao Jeoleena, I am Matteo from Firenze. I remember a few years ago I was going throught a tough time, I was feeling uneasy, and nervous for no reason at all, which of course made it worse. It was like my body was out of place. Then, I don't know why, my wife gave me a tumbled stone, she must have just found it and thought I would like it, nothing spiritual about it. I started rolling the stone, I think it was a smoky quartz, in my hand, and all of a sudden, I felt better. I looked into it and it turns out that there are nerve endings in our hands that reach all of our internal organs. By rolling the smooth stone in my hand, it stimulated my body and relaxed me. All of a sudden, I was fine. I keep a tumbled stone in that funny little pocket of my jeans, you know, the one one the right side that nobody ever uses. Every so often I take it out and hold it. What can I say, it works for me. Maybe if people replaced their cell phones with tumbled stones, the world would be a better place!
