A pretty, large thumbnail specimen of very nicely crystallised bright silver Galena, golden-tan Siderite, minor black Sphalerite and semi-transparent, colourless nail-head Calcite crystals to around 8 mm tall. From the P?'bram mining district in the Czech Republic, the Galena forms modified cuboctahedral crystals and the Siderite, as translucent, striated, curved tabular crystals.
