Hardness is 1.5 to 2. Related are chlorargyrite and iodyrite. It was first described in 1859 for an occurrence in Plateros, Zacatecas, Mexico where it occurred in a silver deposit as an oxidation product of primary ore minerals.[1] It occurs in arid environments along with native silver, iodargyrite and smithsonite along with iron and manganese oxide minerals.[3] References1. ^1 Mindat page for bromargyrite {{Commons category|Bromargyrite}}{{Halide-mineral-stub}}2. ^Webmineral page for bromargyrite 3. ^1 Handbook of Mineralogy 4 : Bromides|Silver minerals|Halide minerals|Cubic minerals |
