Crater of Diamonds State Park

Crater of Diamonds State Park is a 911-acre (369 ha) Arkansas state park in Pike County, Arkansas, in the United States. The park has a 37.5-acre (15.2-hectare) plowed field which is one of the few diamond-bearing sites accessible to the public. Diamonds have been discovered in the field continuously 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 when the Arkansas Department of Parks and Tourism purchased the site from private owners in Dallas, Texas, which had operated the site as a tourist attraction.
