A Wisconsin man visiting an Arkansas state park found a 5.47-carat canary diamond. The park, Crater of Diamonds State Park, is the only publicly operated diamond site where visitors can look for their own gems.

Bob Wehle of Ripon, WI, found the diamond October 14. It's bright yellow and has no visible flaws. It is the second-largest gem unearthed this year at the park.

Wehle's diamond is identical in quality to a 4.21-carat diamond found in the park earlier this year that is valued at $15,000 to $60,000.
