FIELD Crater of Diamonds is the only diamond-producing site in the world open to the public where you keep everything you find. The 37-acre plowed field sits on an eroded volcanic pipe — and real diamonds turn up regularly, including famous multi-carat stones found by ordinary visitors.
How to search
Three methods, all allowed:
- Surface searching — walk the plowed rows, especially after rain washes the soil and exposes stones (diamonds have a metallic, soapy luster and won’t hold dirt).
- Dry sifting — screen loose soil to find small stones.
- Wet sifting — wash and screen at the water stations; the most thorough method, concentrating the heavy minerals where diamonds hide.
What you’ll find
The finds
- Diamonds — white, brown, yellow
- Amethyst, quartz & agate
- Jasper & calcite
- Peridot, garnet (occasionally)
Access & the law
- Pay the daily admission; the park identifies and registers finds for free.
- Keep what you find — no quantity limit on your own discoveries.
- Bring or rent basic digging & screening tools.
