The park features two covered pavilions equipped with water troughs and tables for wet sifting, alongside open sluice boxes that come with hand-operated water pumps located at each end of the search area. In addition to these facilities, four shaded structures are available, while visitors have the option to bring their own canopies or tents, provided they are properly secured.
Diamonds from this region are formed under immense pressure and heat deep within the Earth’s mantle. Those who strike it lucky may find a diamond resembling a metallic or glassy pebble, contrasting with the traditional sparkling gem often depicted. The volcanic soil is also rich in amethyst, garnet, jasper, agate, and various types of quartz, which visitors are allowed to keep.
The largest diamond discovered in the United States originated from this field: the 40.23-carat Uncle Sam diamond, unearthed in 1924 before the area was designated as a state park. More recently, in September 2021, California resident Noreen Wredberg unearthed a 4.38-carat yellow diamond after just two hours of searching. In 2024, a visitor named Julien Navas also found a 7.46-carat diamond at the park.
In 2017, the park attracted over 180,000 visitors, who collectively discovered 450 certified diamonds in various colors. Among the reported finds were 299 white diamonds, 72 brown diamonds, and 74 yellow diamonds.
Park officials informed Mays that on average, visitors discover one or two diamonds daily, a reminder to “keep your expectations in check.” Most of the diamonds unearthed are about the size of a paper match head, while a one-carat diamond is roughly the size of a pea. Yet, even smaller diamonds provide an exhilarating experience. The park staff offers free identification services, examining finds with loupes to help determine whether a glossy pebble is quartz or a more valuable piece.
A family experience
For those eager to join the ranks of thousands who visit annually, the park remains budget-friendly. Admission fees are set at $15 for adults and $7 for children aged 6 to 12. Visitors have the option to camp overnight, allowing them to return to the search field at dawn. The park also features a small water park during the summer months, acknowledging the challenging heat that can exceed a sweltering 110° Fahrenheit during the diamond hunting season in Arkansas.
Rain can occasionally turn the search area into mud, which seasoned hunters often prefer as it enhances diamond visibility, though it could lead to a messy outing. Mays remarked, “Most visitors leave with a handful of intriguing rocks, newfound knowledge, and a pressing need for a long shower.”
Should you leave the park without a diamond, don’t lose hope; options exist to purchase a diamond-making machine for around $200,000 on Alibaba.
