The only active diamond mine in the country is the Crater of Diamonds Mine near Murfreesboro, Pike County, Arkansas. There, recreational prospectors have been finding up to a few hundred carats of diamonds per year since the early 1970s. Most of the stones are white, yellow, or brown in color, but a wide range of diamond colors has been found at the mine. See photo at the top of this page.
