He found the rings on the beach. Then he found the owner.

What a great story! BBC News

While skimming the sand with his metal detector, Mike Cogan uncovered treasure on a Long Island, N.Y. beach.

Just two inches below the surface, he found two rings — an engagement ring and wedding band — lost by a woman vacationing with her family.

Using Facebook, he sent out a picture asking his friends to reach out to their networks to find the ring’s owner.
Sure enough, the owner was found.

I love Cogan’s comment on his Facebook, “This return was more exciting than finding the rings”.
