This town, settled in 1848, derived its name from its crystal clear springs. Among the richest spots in this vicinity, its diggings produced a 25 pound nugget, one of the largest ever found in El Dorado County. Its most thriving period was in 1851. Later it became a contender for the county seat. Through its lumber, lime production, and agriculture, Diamond Springs retained some of its early importance.
