Crater of Diamonds State Park


Crater of Diamonds State Park in Arkansas is the only place in the world where you get to keep any diamonds you find. Pickings aren't exactly slim: more than 75,000 sparklers (an average of 600 per year) have been found in this 37-acre diamond field, including the so-called Uncle Sam, which at 40.23 carats, is the largest diamond found in North America. Exhibits, films, and presentations in the park’s Discovery Center discuss the mine’s unusual history, teach different mining techniques, and give tips on the best places to find stones. Then, can rent some basic equipment and head on out. You might find white, brown, or yellow diamonds here. Most are small---about the size of a pea and weighing 20 to 25 points (there are 100 points in a caret). That said, in the past decade, several specimens have weighed in at more than 5 carets (one recent find came in at 8.66). Never fear if you don't happen upon a diamond: you just might find an amethyst, agate, jasper, quartz, or other semi-precious stone instead.Other park amenities include a water play area, a restaurant, a gift shop, and a campground with tent and full-hookup sites.
