MURFREESBORO, Ark. (AP) - A Murfreesboro man searching for diamonds at the Crater of Diamonds State Park has found a 3.2-carat gem.

Billy Moore says he initially thought he had found a wadded-up piece of gum paper while sifting on Oct. 30 in the park's 37.5-acre diamond search area.

The 45-year-old Moore says he rolled his find around with his finger and saw a shiny side.  The diamond is about the size of an English pea, has a rough, rounded shape and is sparkling white.

He's named the diamond "The Frosty" because of its appearance. He says he plans to sell the gem, which was the second-largest diamond found this year at the park.

Crater of Diamonds is the only diamond mine in North America where the public can search for diamonds and other gems and keep them.
