    Description

    Chlorargyrite var. Bromian & Native Silver
    Broken Hill Proprietary Mine, Broken Hill, Broken Hill district, Yancowinna Co., New South Wales, Australia

    "A fenestrated intergrown flat cluster of chlorargyrite crystals with a little native silver growing up at the top. I got the specimen from the Earl Calvert collection when I sold it for the family many years after Earl Calvert died. It used to be a brighter green. I keep it green side down in a closed box to protect it from reacting with the air as much as possible. This mineral used to be called embolite."
    - Rock H. Currier

    Wasn't the air that was/is the problem, it's light. Being a Silver Halide mineral it is the natural equivalent of photographic film - they both share the same chemistry. He was right to keep it in a closed box, just for the wrong reason. If you know your Broken Hill Mine(s) minerals, then you can tell how good this one is - not only is it esthetic (a term not usually applied to Bromian Chlorargyrite specimens), there are also Native Silver crystals as an added highlight. There is a custom labeled acrylic base.
