Located in Murfreesboro, Arkansas, Crater of Diamonds State Park is one of the only places in the world where the public can search for real diamonds in their original volcanic source. The park is situated on an eroded volcanic pipe that erupted millions of years ago, bringing precious gems to the surface. Since becoming a state park in 1972, thousands of diamonds and semi-precious gemstones have been discovered by lucky visitors.
Visitors are invited to explore a massive 37.5-acre plowed field, which is periodically tilled to bring new rocks and minerals to the surface. Armed with sifting screens, shovels, and buckets, rockhounds of all ages can spend the day searching the dirt for white, brown, and yellow diamonds. Any gemstone, mineral, or rock you find during your search is yours to keep, regardless of its value.
Beyond the thrill of the hunt, the park offers a visitor center with interactive exhibits, walking trails, and a seasonal water park. Over the years, significant finds have made headlines, including the 40.23-carat Uncle Sam diamond, the largest ever found in the United States. It remains a fascinating destination that perfectly blends geological history with the excitement of hands-on discovery.
Ratings
parkVisitor Tips
- ◆ Visit a day or two after a heavy rainstorm, as the rain washes away loose dirt and makes shiny diamonds easier to spot on the surface.
- ◆ Rent digging and sifting tools at the park's Visitor Center, or bring your own screens and small shovels to save on rental fees.
- ◆ Stop by the Diamond Discovery Center first to view real rough diamonds so you know exactly what to look for while searching.
- ◆ Wear old clothes and sturdy, waterproof boots, as the plowed search field can become incredibly muddy and messy.
Heads Up
- ◆ Summer temperatures in Arkansas can be extremely high, and there is absolutely no shade or shelter out in the open 37-acre search field.
- ◆ The search field can become a thick, sticky mud pit after heavy rainfall, which can make walking difficult and easily ruin footwear.
