Crater of Diamonds State Park: Find Real Diamonds in Arkansas

Crater of Diamonds State Park stands out as the sole location globally where the public can prospect for genuine diamonds straight from their volcanic origin. Nestled in Pike County, Arkansas, this 911-acre park features a 37-acre plowed field on the eroded surface of an ancient volcanic pipe, drawing adventurers eager to unearth sparkling treasures.

The Geological Marvel Behind the Diamonds

Deep beneath the earth’s surface lies the story of Crater of Diamonds. Approximately 100 million years ago, a violent volcanic eruption formed the Prairie Creek Pipe, a lamproite vent that propelled diamonds from the mantle to the surface. Over time, erosion exposed this diamond-bearing field, making it accessible today. The park’s 37.5-acre search area continuously yields finds because heavy rains wash new gems to the top of the plowed soil.

Diamonds here vary in color—white, brown, yellow—and size, though most are under one carat. Visitors also discover amethyst, garnet, jasper, agate, and quartz. On average, two diamonds surface daily, with over 37,377 recorded since the park’s establishment as a state property in 1972 as of January 2026.

A Rich Legacy of Discoveries

The site’s diamond history ignited in 1906 when local farmer John Wesley Huddleston stumbled upon the first gems. This sparked prospecting booms, rival companies, and eventual public opening in 1952 as a tourist spot. Arkansas acquired it in 1972, transforming it into a state park that has hosted thousands annually.

Iconic finds include the 40.23-carat Uncle Sam, the largest diamond ever dug in the U.S., discovered in 1924 by Wesley Oley Basham and now in the Smithsonian. Others shine bright: the 16.37-carat Amarillo Starlight, 15.33-carat Star of Arkansas, and 8.52-carat Esperanza. More recently, the graded-perfect Strawn-Wagner Diamond emerged in 1990, proving the field’s enduring allure.

Planning Your Diamond Adventure

Reaching the park is straightforward via State Highway 301 near Murfreesboro, about two hours southwest of Little Rock amid tall pines. Admission grants access to the search field, where all discoveries are yours to keep—no value limit. The park operates year-round, but spring and fall offer milder weather; summer heat prompts early starts.

• Hours: 8 a.m. to sunset daily, weather permitting.
• Fees: Small entry charge; tool rentals available on-site.
• Best Times: After rains, as water redistributes gems.

Essential Tools and Search Strategies

Arrive prepared or rent from the park—ladders, battery-powered, or motorized tools prohibited for safety. Basic kit: small shovel, sifting screen, buckets, and tweezers for pinpointing.

1. Surface Scanning: Walk the field post-plowing or rain; look for greasy, octahedral crystals.
2. Digging Method: Excavate small pits (max 3×3 feet), sift soil in pans.
3. Washing Technique: Rinse finds in creeks to reveal sparkle; staff aids identification.

Park experts demonstrate methods and identify hauls for free at the visitor center. Exhibits showcase uncut diamonds, geology, and history.
