A French tourist found a 7.46-carat diamond while visiting the Crater of Diamonds State Park in Murfreesboro, Arkansas.

Julien Navas, of Paris, found the diamond earlier this month on the surface of the park’s 37.5-acre search area, according to a news release from Arkansas State Parks.

The park had received more than an inch of rain a few days before Navas’ visit, according to the news release, which made it a wet and muddy day. After buying his ticket and renting a diamond-hunting kit from the park, Navas got to work.

“I got to the park around nine o’clock and started to dig,” Navas said in the news release. “That was back-breaking work so by the afternoon I was mainly looking on top of the ground for anything that stood out.”
