An Arkansas man found a 2.37-ct. white diamond at the Crater of Diamonds State Park in Murfreesboro, the world’s only diamond-bearing site where visitors are allowed to search for and keep the gems they find, The Associated Press reports.

Gary Dunlap of Jefferson named the diamond he found the Star of Thelma to honor his wife of more than 10 years, the AP reports. Dunlap’s find was the fourth-largest diamond found in 2006. In all, 486 diamonds have been found at the park this year.

Dunlap found the gem Sunday while looking near a Bois d’Arc tree on the park’s 37.5-acre search field, the AP reports. He said he felt certain the shiny stone was a diamond when he picked it up off the ground. Dunlap reportedly said he has visited the park about a dozen times but this was his first diamond find.
