Carrollite was discovered in Carroll County, Maryland, and recognized as a mineral species in 1852. It is named for Carroll County. Carrollite is collected for its mineralogical rarity, rarity of sizeable crystals, unusual chemical composition as one of the relatively few cobalt-bearing minerals, high degree of cubic-crystal development, and associations in composite specimens with such minerals as quartz and calcite.
