This is a superb miniature of an old classic species from this important silvermining district. More importantly, and unlike so many other such surviving examples, it is on matrix - and contrasting matrix at that! These crystals are not as massive as some I have seen from the locality but in fact are much more elegant and sharply crystallized than you normally see. Though it has lost the original labels, tags glued to the bottom indicate that it came from the Metzger collection through the Schwethelm collection to Leithauser. Again, as with most of his German specimens, it is not only imporant but also as aesthetic as you could ask for in such a creature.
