Tana Clymer dug up a 3.85-carat diamond at the Crater of Diamonds State Park in Arkansas. Clymer, a 14- year old girl from Oklahoma City, was digging in the park for a couple of hours when she found the teardrop-shaped yellow diamond. The Crater of Diamonds State Park is the only diamond-producing park in the US where the public could freely look for diamonds. Clymer gave her diamond the name "God's Jewel."

Assistant Park Superintendent Bill Henderson said, "Tana told me that she was so excited, she couldn't sleep last night. She's either going to keep the diamond for a ring, or, if it's worth a lot, she'll want that for college."

According to the park's website, the mine was bought by the state of Arkansas using revenue bonds that totaled USD 846,000. It was sold by General Earth Minerals (GEM), a portfolio firm of GF Industries. The parent company had financial problems in 1970, which eventually led to the sale of the Crater of Diamonds State Park that was completed on March 15, 1972.
