![]() | The Arkansas Diamond Mine at Crater of Diamonds State Park is the only producing diamond mine in the United States and the only diamond mine in the world open to the public. Diamonds were first discovered in 1906 when John Huddlestone found two strange crystals in the soil of his farm. His farm was right above a volcanic pipe filled with lamproite. http://www.craterofdiamondsstatepark.com/ | ![]() |
