I have been collecting rocks for almost two years now. They bring me so much company and joy. As you look through the individual photos, some of the rocks that have holes in them that I found outside, have small pieces of what I believe to be crystal quartz on the inside. I found many of these while rockhounding. It is a hobby of mine. My favorite rocks are those who look like old souls. I love Petrified Wood. Bring it on!
