A 14-year-old found a 7.44-carat diamond last week at Arkansas' Crater of Diamonds State Park, where visitors can look around for gems and keep whatever they find.
The shiny, dark brown rock discovered by Kalel Langford turned out to be the seventh-largest diamond found at the park since it opened in 1972.
Langford, who was visiting the site with his parents, had only been there for about 30 minutes when he spotted the gem. It's about the size of a pinto bean and worth around $500,000.
Not bad for half an hour of work.
Langford named his find Superman's Diamond because he's a fan of comic books. His parents must be, too, since his first name, Kalel, is almost identical to the Man of Steel's birth name (Kal-El) back on Krypton.
