(ABCNEWS.GO) — When Oklahoma teenager Tana Clymer heard about a young boy who'd found a 5-carat diamond at Arkansas' Crater of Diamonds State Park earlier this year, she wanted to try her luck.
Tana, 14, and her parents traveled to the park, an eroded surface of an ancient volcanic crater and the only diamond-bearing site open to the public, from their Oklahoma City home. She had been digging and sifting through dirt in the 37-acre park for about two hours when something caught her eye.
"I thought it was a piece of paper or foil from a candy wrapper," Tana said, according to the Arkansas State Parks website.
It was a jellybean-size, teardrop-shaped, yellow stone.
