A Baton Rouge, LA woman visiting Arkansas' Crater of Diamonds State Park in Murfreesboro found an apparently flawless 2.09-carat white diamond the size of a tooth. Rhonda Bankston reportedly says she found out about the park's surface diamond prospecting on a show about finding cash and treasure. She was into her second day of prospecting by surface searching over a newly plowed field with friends when she spotted the gem. The park is located on the eroded surface of the world's eighth largest diamond-bearing deposit and visitors pay a fee to surface search there.
