I've found two wedding rings in the Caribbean, one in Montserrat, and one in Dominica. Both were in shallow water where waves and currents moved a lot of sand, exposing the sudden bright flash of gold. The owners were probably wading unsteadily on what were difficult beaches. I think it's a bad idea to wear valuable rings while swimming or diving. I don't understand why people bring expensive jewelry on vacations, especially those that involve water sports. Is it really that important to wear a wedding ring on holiday? Will people think you are an immoral wanton, fornicating and cohabiting without the benefit of matrimony? Leave those rings home.
