In which state would you find the only active diamond mine in the United States?

It's finders keepers at the Crater of Diamonds State Park in Murfreesboro, Arkansas. The only public diamond mine in the world, Crater of Diamonds offers you a one-of-a-kind adventure - the opportunity to hunt for real diamonds and to keep any mineral you find.

Since diamonds were first discovered on the site in 1906, over 75,000 diamonds have been unearthed.

When John Huddleston plucked two diamonds from the greenish-colored dirt of his farm, a hysteria known as "diamond fever" ensued. Although the excitement has since waned, interest in Arkansas's diamond mine remains high. About 120,000 people come to Huddleston's old farm site, now the Crater of Diamonds State Park, each year to search for these precious gems.

The largest documented diamond find is the 40.23-carat "Uncle Sam" diamond, which was discovered in 1924. The largest diamond retrieved since the Crater of Diamonds became a state park was the 16.37-carat "Amarillo Starlight," discovered in 1975.

The site became a state park in 1972 after the Arkansas Department of Parks and Tourism purchased the site from the Arkansas Diamond Company and Ozark Diamond Mines Corporation, who had operated the site as a tourist attraction previously.
