Christi Hansen of Evansville said she wore the ring every day for 13 years until the half-carat marquis diamond disappeared, and she searched everywhere for the jewel -- even in several bags of trash -- to no avail, WFIE-TV, Evansville, Ind., reported Thursday.
Hansen said the diamond had been missing for more than four years and her husband bought her a replacement ring. She never thought she would see the diamond again.
However, Wayne Sutton, a technician with Alpha Laser, found the missing diamond while working on Hansen's old work printer.
"I was just looking and it was like right in here," Wayne said. "I thought it was a piece of dust or something, piece of paper, but I was blowing it around and trying to get it out and it wouldn't move. I just grabbed it and I was looking at it and was like, 'this looks like a diamond."
Christi said she was overjoyed to get the diamond back.
"I don't know what to think, what to feel. I just, I couldn't believe it, what he was showing me," Christi said.
Wayne said he was happy to return the stone.
"It's going down in my memory bank as the number one best time at work ever," Wayne said.
