An extinct volcano in Arkansas hosts the only public diamond mine on Earth

Crater of Diamonds State Park in Arkansas is home to the only public diamond mine on Earth. This park is situated on an extinct volcano, providing a unique geological setting for diamond exploration. Since the park's opening in 1972, visitors have discovered over 35,000 diamonds, making it a popular destination for those seeking to find their own precious gems. The park's diamond-bearing soil is the result of volcanic activity millions of years ago, which brought the diamonds to the surface. Visitors are allowed to search for diamonds in the park's designated mining area, using tools and techniques provided by the park. The largest diamond found at the site, the Esperanza, weighed over 8 carats and was discovered in 2015. The Crater of Diamonds State Park offers a rare opportunity for the public to participate in diamond mining and potentially uncover their own valuable finds. This unique natural attraction continues to draw visitors from around the world, eager to experience the thrill of discovering their own piece of geological history.
