The incorporated town of Kimberly, a sparsely inhabited area on the south side of Murfreesboro, Arkansas, began in late 1908 as an ill-fated land-development project spanning almost 240 acres (0.97 km²). At the time, the recently discovered Arkansas diamond field was still generating a speculative heyday, and the enterprising property owner, Millard M. (M. M.) Mauney, envisioned a dynamic settlement based upon a future mining industry. His location was perfect. The diamond field lay only a half-mile away.
