ROCHESTER — A woman is trying to solve the mystery of a 1955 class ring found along a gravel road near Sargeant in Mower County.

Barb Nelson spotted the ring in 1973 while riding a horse over to her neighbor’s house, The Post Bulletin reported .

“I was walking slow, and I was always looking at the ground to see if I could find a pretty rock, and there it was,” Nelson said.

After initially failing to track down the ring’s owner, she set it aside in a jewelry box. Nelson recently came across the ring again and is hoping to find answers.

“It’s just been sitting around and I don’t seem to get anywhere,” Nelson said.

The ring is made for a woman and is about a size six, according to Nelson. The ring includes the initials G.S., she said.

“She’d be about 81 or 82, if she’s still alive,” Nelson said, thinking of the owner.

The ring is from Hammond High School and dated 1955, Nelson said. While there’s a town named Hammond in Minnesota, there’s no Hammond High School in the state.

Nelson said she’s checked with Hammond High Schools around the U.S. but hasn’t found a person matching those initials who graduated in 1955.
