Geology of Arkansas Diamonds
Volcanic Origins and Erosion
The diamonds in Arkansas originate from a rare type of volcanic formation known as a kimberlite pipe, forced up from deep within the Earth millions of years ago. Over time, erosion exposed this pipe at the surface, and what was once buried under continents of rock became a shallow field where diamonds could be found with simple tools and effort.
Because the site has been actively searched for over a century, new visitors still regularly discover diamonds. Understanding the local geology helps you appreciate why this field remains productive and how surface material can still hold exceptional crystals.
Where Diamonds Are Found in Arkansas
Surface Soil and Crater Floor
Most visitors search the 37.5-acre Crater of Diamonds field, focusing on the surface soils that have been naturally weathered and disturbed. Diamonds are concentrated in a soft, reddish-brown clay that is easy to sift through, and frequent rains can wash new material to the surface.
While significant diamonds have been found in historic mining shafts and deeper deposits, the majority of public finds occur in the top layers of the search area. Systematic sweeping and careful examination of each soil type increase your chances of spotting these valuable finds.
Practical Tips for Diamond Finding
Tools, Timing, and Search Techniques
Visitors typically search with basic tools such as sieves, colanders, and small shovels provided or purchased on site, using water from park spigots to screen soil effectively. Early morning visits and periods after heavy rain often yield the best results, as fresh soil is turned and visibility is improved.
Walking slowly, scanning the ground carefully, and focusing on shaded or darker portions of the field can help you distinguish diamonds from surrounding gravel and mica. Most successful hunters develop a routine that balances thoroughness with endurance across the search area.
History and Public Access
From Mine to Public Park
Commercial diamond mining at this site began in the early twentieth century and operated sporadically until the 1970s, when the state established the area as a public recreational park. By allowing the public to keep any diamonds they find, the park has transformed a former industrial operation into a unique outdoor experience.
Over the decades, thousands of diamonds have been unearthed by visitors, ranging from tiny crystals to stones suitable for mounting as jewelry. Historical records and interpretive exhibits in the park help connect each discovery to the long legacy of diamond mining in Arkansas.

- Use water responsibly and restore the search area as closely as possible to its natural condition.
- Report rare or exceptionally large finds to park staff for documentation.
