I wanted to go gem mining while we were on vacation, so one night we went over to pigeon forge and stopped at a gem mining stand. You buy a bucket of dirt and they give you a screened box and you get to pan for gems. It was alot of fun and we did get several nice precious stones. One of the gems was a 6 carat ruby, the gem mining stand had a jeweler on hand and we made our ruby into rings for us. Very cool souvenir.
