Lost Diamond and Sapphire ring found with metal detector in Boothbay Harbor, Maine

I received a call last Friday afternoon from Steve after his wife Kathy dropped her diamond and blue sapphire ring into the water from the Boothbay Harbor foot bridge. The water depth was around 5 feet and rising with the flooding tide, but I was able to recover it despite the challenge of the ring being amongst numerous nails, screws, bottle caps and other metallic items under the bridge.
