Crater of Diamonds

The account

A 37-acre plowed field over the throat of an ancient volcano, the only diamond mine on earth where the public digs and keeps. The 40-carat Uncle Sam came out of this dirt in 1924; a 6-carat canary stone came up in January 2026. The park turns the field over like a garden, and after every hard rain, somebody's afternoon changes.

Leads, where the trail points now

• What you can keep: White, brown & yellow diamonds, finders keepers, no exceptions. Confirm the site's current rules and any day fee before you go.
• Where: Murfreesboro, Pike County, AR. Arkansas state park, modest entry fee; any rock, mineral, or diamond you find is yours regardless of value.
• Best practice: record anything notable, leave the ground as you found it, and check the latest access notices before you travel.
