The gold ring has a rectangular cut estimated at 10 karats. It's believed to be from the Nuestra Senora de Atocha that sank off the Florida Keys during a 1622 hurricane. Divers from Mel Fisher's Treasures found the ring Thursday about 35 miles from Key West.Mel Fisher's website is here.
A spokesperson said the ring's estimated value is based on the stone's 2.7- by 2.5-centimeter size and the value of other emeralds from Atocha.
