Hureaulite is a hydrous manganese phosphate and the namesake for the hureaulite group of phosphates and arsenates. Vauquelin (1825) first published an analysis of the mineral, followed shortly by its description by Alluaud (1826). The mineral name recalls its type locality at Hureaux, France. Crystal structure solution by Moore & Araki (1973) established its currently accepted formula.
This specimen consists largely of hureaulite. Pink hureaulite crystals to 4 mm are perched on top of a granular pink mass; later blue-black rockbridgeite provides contrast. A rich specimen. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
