Lost ring in Anderson County Park

I was contacted by Josh and Stephanie. They were visiting friends from out of town and went swimming at a local swimming hole at Anderson County Park. At some point Stephanie noticed her engagement ring was missing. I spent several hours snorkeling, looking for her ring with no luck. Josh and Stephanie had left town to go back home heart broken. I refused to give up, I came back two days later with scuba gear and found it in 15ft of water in the deepest part of the swim area. I cleaned the clay off her ring and mailed it to their home in Alabama.
