Bromellite, whose name derives from the Swedish chemist Magnus von Bromell (1670-1731), is a white oxide mineral, found in complex pegmatitic manganese-iron deposits, but is more frequently made synthetically. This is a rare mineral to encounter in its natural state, but it has been made synthetically for over 40 years.
