The Crater of Diamonds State Park is located near Murfreesboro, Arkansas. The park is a 36 acre field that is the eroded surface of an extinct volcanic pipe. It is the only diamond mine in the world that is open to the public. Visitors search for gems, and can keep whatever they find. Carter of Diamonds became a state park in 1972, and since then over 22,000 diamonds have been carried home by visitors. Amethyst, garnet, jasper, agate, quartz and more can also be found here. Digging tools are available for rent, and the park staff provide free identification and certification of diamonds.
