The park in Murfreesboro, Arkansas, is about a four-and-a-half hour drive from Oklahoma City, and from which a 14-year-old Oklahoma girl has a pricey find in her possession.
"I didn't think I was going to find anything," Tana Clymer said.
When Tana Clymer and her family went to the Crater of Diamonds in Arkansas, they spent a couple of hours searching for a diamond. She'd nearly given up, in fact, she said she started running through the 37-acre diamond field to leave.
"I had this feeling that I needed to walk," she said.
And when she walked instead, she said something caught her eye.
"I saw something goldish and shiny," Tana said.
She picked it up. It was small - about the size of a jellybean - and sort of yellow in color, she said.
"It was not a candy wrapper or a marble," Tana said.
"She came straight up, and the minute she opened her hand, I knew she had something," said Brian Giordano, Tana's dad.
Tana did have something - a 3.85-carat canary diamond. And when she showed it to the folks at Crater of Diamonds, the only public diamond producing site around, she got excited.
"When they said they haven't found one like this in a long time, my heart just stopped," she said.
It's not very big but worth thousands. Tana's brother Jackson and sister Kierstan and her parents are all pretty excited, but the whole family is keeping it all in perspective.
"I named it God's jewel 'cause I think God led me toward it," Tana said.
The family says the diamond isn't at their house anymore. They were so concerned about keeping it safe, they've put it in a safety deposit box.
