Locality type: Mine Classification Species: Native Silver Formula: Ag Comments: Minute arborescent crystals generating acanthite in storage. Special Storage/ Storage in a low humidity environment seems to prevent the formation of acanthite (silver sulphide), which if allowed to proceed unchecked can completely replace the silver on a specimen in a period of a few years.
