Crater of Diamonds National Park - Arkansas

Crater of Diamonds State Park is a 911-acre Arkansas state park in Pike County, Arkansas, in the United States. The park features a 37.5-acre plowed field, one of the few diamond-bearing site accessible to the public. Diamonds have continuously been discovered in the field since 1906, including the graded-perfect Strawn-Wagner Diamond, found in 1990, and the Uncle Sam, found in 1924, which at over 40 carats is the largest diamond ever found in the United States.

The site became a state park in 1972 after the Arkansas Department of Parks and Tourismpurchased the site from the Arkansas Diamond Company and Ozark Diamond Mines Corporation, who had previously operated the site as a tourist attraction.
