How to Spend the Day at Crater of the Diamonds State Park
First, dress for success and mud. The diamond field is uncovered dirt so I recommend water shoes or rubber boots. The field lacks trees so wear a hat and sunscreen. The park does offers an area to wash off muddy shoes.
After attending the demonstration, rent your tools and head to an area that speaks to you. Obviously the areas closest to the buildings are the most searched.
If it has rained recently, you can walk through the field. The rain could have undercovered a diamond for you.
The second method requires getting dirty. Grab a trowel and dig in the first six or 12 inches of dirt then put it through the screen to remove the dirt and harvest the pebbles. You are looking for a shiny pebble that looks almost metallic.
The soil is hard-baked clay and the gemstones might be inside of a dirt cluster so you have to break up the rock clusters. This method is followed by visiting the sluice area, a covered pavilion with water troughs. There you will clean up the pebbles looking for a diamond to appear.
Finally, if you’ve found some pebbles, the park staff will identity each for you for free. If you’re lucky, they will weigh your gemstone as well.
Cool Facts about Crater of the Diamonds State Park
My first question, why are they letting us mine for diamonds.
So here’s a brief history, the first diamond was discovered in 1906. The area was mined by commericial operations for decades though unsuccessfully. So there are diamonds, just not enough to make a profit.
In the 1950s, the area became a tourist attraction. In 1972, the Arkansas State Park system bought the land to be used as a state park. It’s now one of the most popular state parks in Arkansas.

Our Experience at Crater of Diamonds State Park
We paid our admission and rented some tools for about $40 and we were ready to discover a diamond in the rough. Then the park ranger told us we needed to attend the demonstration on diamond hunting. OK, we headed to diamond digging school and felt even luckier.
With a little knowledge and absolutely no technique, we hit the 37-acre plowed field. Just a heads up, it’s dirty so leave the cute sandals in the car.
We dug for an hour before we were hot and sweaty. Next we took our bucket of treasure-ladden dirt to the covered pavilion to wash our soil through a fine screen. This was a bit tedious but the thrill of discovering the next big diamond pushed me forward. My kids disappeared and splashed in the water trough instead. So I mentally claimed all the diamonds in my dirt.
With a handful of shiny rocks, I headed to the Diamond Discovery Center feeling lucky for its free diamond identification. After waiting in line for the next available gemologist, I handed over my collection.
I had a fine collection of quartz along with some minerals I don’t remember the name of, mainly shiny, tiny rocks. After spending a couple of hours working in the dirt, I bought the 50¢ glass vial for my treasures .
But don’t let that discourage you. I didn’t strike it rich but it’s a fun day and you will learn about geology and mining. Afterwards you can splash at the water park next door.
