Michael Dettlaff, 12, had only been searching for 10 minutes when he stumbled across a 5.16 carat diamond.

The North Carolina boy was on vacation with his family at Arkansas' Crater of Diamonds State Park when he found the honey brown diamond on July 31. He named it God's Glory Diamond, park officials said.

According to the Park's website,"the policy here is 'finders, keepers,' meaning the diamonds you find are yours to keep."

Park officials said the diamond is about the size of a jelly bean and is the 328th diamond found this year.

Michael's diamond is the 27th largest found by a park visitor since Arkansas' diamond site became a state park in 1972. It is the eighth-largest brown diamond that has been certified by park staff.

More than 75,000 diamonds have been found at the site since the first discovery in 1906 by John Huddleston, the farmer who owned the land at the time.

The largest diamond ever discovered in the United States was unearthed at the site in 1924 and weighed 40.23 carats.
