Karl Bly is an expert diver whose hobby is searching the American River outside Sacramento, California, for lost treasures. On one of his dives, he spotted something shiny at the bottom of the river. He lifted it out of the muck 8 feet below and got quite the surprise: it was a gold wedding band with a diamond. He was able to locate the rightful owner: 31-year-old Adam Papini, who recorded the precise moment he plunged into the river’s waters. It was then that the ring slipped off his finger.
