A Geological Wonder
The park sits atop an eroded lamproite volcanic pipe, an ancient geological formation that brought diamonds to the surface some 100 million years ago. While commercial mining attempts failed in the early 20th century, the site found its true calling as a state park in 1972. Since then, over 35,000 diamonds have been found by visitors.
It isn’t just about diamonds, though. The soil is rich with other semi-precious gems. Visitors frequently find amethyst, agate, jasper, and garnet. The park’s Diamond Discovery Center provides a fascinating look into this history, teaching visitors not just how to hunt, but why this specific patch of Arkansas dirt is so geologically significant.

Planning Your Visit
Crater of Diamonds is located in Murfreesboro, a small town about two hours southwest of Little Rock. You will need a car to get here. While the park rents equipment (buckets, shovels, and knee pads), lines can be long in the morning. Bringing your own gardening tools and a small wagon to haul them is a pro move that will save you time and money.
Dress for mess. The volcanic clay is notorious for staining clothes, especially if you are wet sluicing. Wear old sneakers or boots, and bring a change of clothes for the drive home. If you are visiting in summer, start your day as soon as the gates open at 8:00 AM to avoid the midday sun, as there is absolutely no shade out in the diamond field itself.
