This is more of an aesthetic, small cabinet specimen, but good for a well rounded Pribram collection. The crystals are large and discoidal and measure 2cm across. The entire specimen is covered by a frosting of clear clacites or even dolomite. If you look at the backside, you'll see dark cleavages of Siderite, an indication of how the geochemistry had changed.
