Osarizawaite is a rare mineral that was first discovered in Japan in 1985. As it is a little-known mineral, there are no widely recognized synonyms for it. However, one could use words that describe its physical properties such as lustrous, fibrous, metallic, or blackish-gray. Additionally, one could use terms that describe the location or geology of where it was found such as volcanic or hydrothermal. In scientific papers or reports, it may be sufficient to simply refer to it by its chemical formula, PbCu(Al,Fe)_2(SO_4)_4(OH)_6·3H_2O. Regardless of how it is referred to, osarizawaite remains a unique and fascinating mineral for geologists and mineral enthusiasts.
