Bromargyrite is an ore of silver, and is very similar to Chlorargyrite, with which it forms a solid solution series. Bromargyrite contains the halogen bromine combined with silver, whereas Chlorargyrite contains chlorine with silver. Bromargyrite and Chlorargyrite can be visually indistinguishable from one another, and will often form in the same deposits. The intermediary mineral of this series, known as Embolite, is usually classified as a bromine-rich variety of Chlorargyrite. Bromargyrite and Chlorargyrite are also chemically similar to the rare mineral Iodargyrite, which has iodine in place of the bromine/chlorine.
