A very beautiful pyrite specimen, with several very sharp crystals nestled in a cluster of quartz crystals. The pyrite has the mirror-like luster that characterizes the best pieces from this mine-- you can actually see the reflections of the quartz crystals on the pyrites' surfaces.
The main crystals are all intact, though a couple of the peripheral ones have contacts (I mean, it had to be extracted somehow...) This is an excellent (and very beautiful) piece-- the ones with quartz always seem to be the most sought after, though unfortunately they are considerably less common.
