The Star of Murfreesboro is a 34.25 carats (6.850 g) blue diamond that is eleven-sixteenths of an inch (17 mm) in diameter. The diamond was found by John Pollock at the Arkansas Diamond Mine near Murfreesboro, Arkansas. It's considered the largest diamond ever found by a tourist -- and it was valued at $15,000 when it was found in 1964. Adjusted for today's inflation, it would be worth about $95,452.
