Crater of Diamonds State Park

The only area in the world where you can find diamonds on your own, Crater of Diamonds State Park is located in the southwest of the state. Since 1906, when John Huddlestone discovered two shimmering crystals, the region has drawn prospectors with the most recent "diamond rush" of visitors looking to try their luck.

Visitors, who are free to keep whatever they find, have uncovered an astounding 29,000 jewels throughout the years. Although prospecting for valuable gemstones is the main draw, there is a Diamond Discovery Center that provides an intriguing look at prospecting's past.

There are also several old buildings to explore, a cafe, a store, and an aquatic playground on the property. While tourists discover an astonishing two diamonds every day on average, Shirley Strawn discovered the Strawn-Wagner Diamond in 1990, which is still regarded as the sole flawless diamond ever unearthed.
