Used to be able to go to Crater of Diamonds, Arkansas my grandmother was a rock hound. She’d go and scratch around in a plowed field with other enthusiasts.
It’s a state park now.
Not sure if they still allow digging or surface gathering.
I know they did just a few years ago, I'm to lazy to search for a headline, but it seems like someone found a diamond worth some jack... probably been 5-6 years ago.
