It's almost like that e-bay commercial

Okay, not really.

CNN - Lost ring comes full circle 20 years later

A college ring lost more than 20 years ago by a former undercover officer for the CIA has been found in an underwater cave off the coast of Africa.

[. . .]

Lopez, a 1976 Notre Dame College graduate and former CIA undercover officer, was stationed at Port Louis, Mauritius, from 1983 to 1985. During a dive, the ring slipped from her finger.

Ruic sent Thiesen's address to Lopez. She has exchanged e-mails with Thiesen, she said Monday, and they're arranging for him to mail it.

Quite an amazing story, especially considering that the ring did not have a name on it. It's actually surprising to me that the one who found it actually made an effort to find the owner.
