A U.K. metal detectorist has worked a near-miracle, reuniting a woman with a beloved chain that held her late mother’s promise, engagement and wedding rings.

The 24-year-old was “devastated” when her necklace chain broke while she was swimming at Les Amarreurs beach in Guernsey last month.

Not giving up hope, Tessa Le Gallez telephoned a local metal detectorist Matthew Kneebone and asked if he could possibly help her get the heirlooms back.

Mr. Kneebone, a stonemason on the rocky island in the English Channel, told her he would be able to find the lost rings when there was a spring tide again.

Sure enough, two weeks later, on September 1, Matthew and Tessa headed back down to the beach—and within ten minutes, Matthew had found the chain. Then, amazingly, within a half hour, all of three of heirlooms were uncovered.
