In 1924, Wesley Basham, an employee of the Arkansas Diamond Company near Mufreesboro (Pike County), found the largest rough diamond ever discovered in the United States, seen in this photograph. Named the “Uncle Sam” after Basham’s nickname, the stone weighed 40.23 carats. Once cut into an emerald shape with a faint rose color, the diamond weighed in at 12.42 carats.
