lost ring in Oklahoma City

I received a call from a lady that had lost their ring while cleaning and repotting some plants. We scheduled a time to meet. There were a couple of places she said it could have been – in the yard where she had dumped the water from the pots, the trash were all the dead plant materials went or the pots with the new plants.  She said she had dumped out the newly potted plants and went through the dirt already so I concentrated on the area where the water and muck was dumped.  After not being able to find anything there I started in on the newly potted plant pot. I got a very faint signal so I put my pinpointer in the pot and there it was! It was just under 1/2 inch of soil.  Great day to help!
