Kimberlite locations.
Two locations in the United States have been worked as commercial diamond mines. The first was a mine near Murfreesboro, Arkansas. It was worked as a commercial diamond mine by a succession of operators in the early 1900s but closed because the deposit was subeconomic. Today it is known as the "Crater of Diamonds" and is operated by the State ...
