    Dimensions: (21.14×13.27×52.79) mm

    Weight: 19g

    Origin: Herja mine, Roumania

    Information: The Herja mining site consists of two groups of veins related with a

    subvolcanic body of pyroxene andesites and porphyritic quartz microdiorite. In these

    groups, the polymetallic mineralized veins contains a wide variety of Pb-Sb sulphosalts

    and is the type locality for fizelyite and a variety of jamesonite. The mineralization occurs

    into various textures: massive, banded, brecious to impregnation and geode. The most

    frequent one are the massive and geode textures. Antimony mineralization is often found

    in these geodes.
