A Minnesota couple on a road trip to celebrate their 10th anniversary found a 1.9-carat brown diamond from Arkansas’ Crater of Diamonds State Park.

Jessica and Seth Erickson made the Crater of Diamonds State Park a featured destination on their 11-state road trip to celebrate the 10th anniversary of their wedding after first hearing about the attraction years ago.

After about an hour of wet sifting, Seth Erickson spotted a gem in the bottom of his screen.

The pair took the find to the park’s Diamond Discovery Center, which verified it was a 1.9-carat brown diamond. The park said the diamond is about the size of a pony bead.

Officials said 581 diamonds have been registered at Crater of Diamonds State Park in 2022.
