Bobbie Oskarson found the diamond Wednesday at the Crater of Diamonds State Park in Murfreesboro, according to the Associated Press. She initially thought it was quartz crystal, according to 9 News, but park officials confirmed its real identity.

Arkansas’s Crater of Diamonds State Park has historically held several such treasures: The “perfect” 3.03-carat Strawn Wagner diamond, the 6.19-carat Limitless Diamond and the 40.23-carat Uncle Sam, the nation’s largest diamond, were all discovered there. Oskarson’s discovery is at least the third such one this year. So-named for an eruption that filled the area with the titular mineral, Crater of Diamonds is the only public place in the world where, for a fee, you can hunt diamonds and keep what you find.
