Crater of Diamonds State Park

The only place in the world where the public can search for natural diamonds in their original volcanic source, Crater of Diamonds offers a one-of-a-kind experience that brings people from all over the world to Murfreesboro, Arkansas. Visitors to the park search a 37-acre plowed field, the eroded surface of a volcanic crater, for a variety of rocks, minerals, and gemstones – any rock or mineral you find is yours to keep. You may bring your own mining equipment to search with (no ladders, battery-operated or motor-driven mining tools allowed), or rent tools from the park.

Your diamond search begins here, where you can prepare for your visit by learning about the Crater's diamonds and how to search for them. At the park's visitor center, you can view real, uncut diamonds and interact with exhibits illustrating the area's unique history and geology. At the Diamond Discovery Center, you can learn more about rocks and minerals found at the park and how to search for diamonds using three recommended techniques. Diamonds come in all colors of the rainbow: the three colors found here at the park are white, brown, and yellow. Amethyst, garnet, jasper, agate, quartz, and other rocks and minerals naturally occur here. Park staff provide complimentary identification of rocks and minerals found at the park, as well as diamond mining demonstrations and other interpretive programs.

As of January 13, 2026 more than 37,377 diamonds have been found by park visitors since the Crater of Diamonds became an Arkansas state park in 1972. Notable diamonds found at the Crater include the 40.23-carat Uncle Sam, the largest diamond ever unearthed in the U.S.; the 16.37-carat Amarillo Starlight; the 15.33-carat Star of Arkansas; and the 8.52-carat Esperanza.

Other amenities include walking trails, picnic sites, 47 Class AAA campsites (50-, 30-, 20-Amp/Water/Sewer), walk-in tent sites, a gift shop, and Diamond Springs Water Park (seasonal), which is a great place to cool off after a summer day of digging for diamonds.
