Crater of Diamonds State Park in Arkansas is the only place in the world where visitors can keep diamonds they find on the surface. This unique public park turns a former commercial mine into an accessible field where families, rockhounds, and photographers search for real diamonds in a peaceful, open landscape.
Unlike traditional parks focused on trails and waterfalls, this location emphasizes hands-on earth science, history, and outdoor recreation. Guests walk through the diamond-bearing field with guidance from park staff, learning how to identify stones and understand the site’s mining legacy. The combination of open fields, interpretive exhibits, and the thrill of discovery makes this a standout destination in Arkansas.

Diamond Hunting Rules And Safety
Tools And Permitted Equipment
Visitors may use hand tools such as colanders, screens, and small shovels provided by the park or brought from home. Metal detectors and heavy machinery are not allowed to protect the site and ensure safety for all guests. The park encourages a slow, careful search method to reduce accidents and maximize visible finds.
Field Boundaries And Hours
Diamond hunting is permitted only within the designated search field and during posted park hours. Rangers monitor the area to prevent unsafe behavior and to enforce rules about digging depth and tool use. Staying within marked boundaries helps preserve the site for future visitors and ongoing public diamond discovery.
History And Formation Of The Site
From Commercial Mine To Public Park
The site began as a commercial diamond mine after a volcanic crater filled with gem-bearing rock was identified. After decades of private operation, the state acquired the land and opened it as a public park focused on education and recreation. This transition preserved the landscape while making diamond hunting accessible to everyone.
Geology That Attracts Diamonds
Diamonds reach the surface through a type of volcanic rock called lamproite, exposed by erosion in the crater. The unique geology concentrates diamonds in the soil and gravel, where visitors can sift and search. Interpretive signs and exhibits explain the science behind this rare Arkansas landscape.

Weather, Accessibility, And Rules
The park is generally flat and easy to walk, though some areas can be muddy after rain. Weather can be hot in summer and cool in winter, so layering and sun safety are recommended.
