(CNN) A little girl in South Carolina got a big surprise while snacking on some Goldfish crackers.
Peyton Postol reached inside the bag and pulled out a diamond wedding ring.
Pepperidge Farms, the company that makes Goldfish, is baffled.
No one has reported a ring missing and employees are forbidden from wearing jewelry while working.
Also, all packages go through a metal detector before being shipped out.
Pepperidge Farms is checking to see if the ring belongs to a worker in Denver, where they make Goldfish.
