Cousins Myriah Calder and Katelynn Peterson had just finished their band concert at Heights Middle School in Farmington when they discovered a diamond ring.
They wanted to make sure it was returned to its rightful owner.
"We were always told to do the right thing and don't take any chances because if that ring was real we wouldn't want to be in possession of it," said Peterson.
They turned in the ring to the school resource officer and a few days later, the school sent out a letter with the band students asking if anyone knew someone who had lost the ring to please come forward.
Eventually the owner claimed it.
"We found out it was her wedding ring of 18 years," said Peterson.
The police department wanted to recognize the girls for their efforts.
So the chief surprised them by showing up at one of their classes to give them a Good Samaritan certificate.
