We have looked all around the web to find the most relevant answer to your query: 

In which state is the only active diamond mine in the U.S.?

• Arkansas:There is only one active, producing diamond mine in the United States. If mining for diamonds interests you, the Crater of Diamonds State Park near Murfreesboro, Arkansas, is where you'll want to go. There is an entry fee of a few dollars that gets you into the park, but this is a one-time fee for the day. You can search all day for diamonds and keep any you find. The diamonds in Crater of Diamonds Park are found in the soil, which makes them easy to look for. The park's personnel plow up the fields periodically, turning up fresh soil to make it easier for searchers to sift through it. You may find other natural gemstones there, too, such as agate, jasper, amethyst, peridot, garnet, and hematite. Source: Geology.com
