Go right after they plow it up to bring them to the surface, right after a rain and walk into the sun looking for a glint. They look like a smooth piece of glass. It looks like it is is in an old volcano, Take a pair of boots to navigate the sticky clay like soil.

I never found anything but they have several on display in their uncut state and I can see how they would most likely be overlooked.

While you are there Northern Arkansas has some of the most beautiful scenery in the US. I was born in the Southern part which is kind of swampy. (duck-hunting capital of the US.)

Thanks for the tips! I’m not a very lucky person, so I can’t see myself finding anything, but it still would be fun to go.

This is the “top” of a kimberlite pipe. Its a remnant of a volcano column that compressed a piece of carbon long enough to turn it into a diamond.
