This cabinet specimen of Pyrite overgrowing Sphalerite on Quartz is beautifully aesthetic. As an added bonus, encircling its base, but not visible from the display face, is a broad band of light tan micro-acicular crystals of what appears to be a zeolite, possibly Stilbite. From St?'bro in the Plze? Region of Bohemia, Czech Republic, micro-crystals of cubic, light golden Pyrite with a brilliant, mirror-like lustre overgrow black Sphalerite crystals of 1 to 4 mm, also with a bright metallic lustre. This association covers at least one third of a drusy crystallised undulating bed of milky grey micro-crystals of Quartz. A showy specimen with fascinating morphology which comes with the previous collector's card label.
