(CNN) -- A bank branch manager hit the jackpot at Crater of Diamonds State Park in Arkansas.
Kevin Kinard found a nine-carat diamond at the park when he was there with friends on Labor Day.
The marble-sized diamond is the second-largest diamond found in the park's history.
More than 75,000 diamonds have been found there since the first ones were discovered in 1906.
The park has a finders keepers policy, so whatever you find is yours.
Kinard says it's unique that he found a 9.07 carat diamond on Sept. 7, or 9/7.
The 33-year-old has been searching for diamonds there since a second-grade field trip.
