I was out detecting in a local lake in about 4 1/2 feet of water and scored my first ring with hopefully some value to it. The silver band reads .925 9 NV which I found out means that it is .925 silver and the 9 NV means "Nevada silver made in England". The silver has turned to black. Not sure if the blackness might be able to tell how long it was in the water? The stone really sparkles in natural light. It appears to be about 2 carats in size. Any help would be appreciated.
