Another day, another story about a lost class ring. This latest one, shown above, belonged to a Virginia high school student named Shannon O'Donnell, who lost it while riding an amusement park ride in 1999. It was recently found by man named James Lawrence, who returned it to Shannon's high school.
Although Shannon's name was etched into the ring's inner band, the school's staff no longer had contact info for Shannon. So they put a photo of the ring on the Facebook page for the school's alumni, which set the wheels in motion for Shannon to reclaim her ring. You can read further details in this article.
