| Nice! Dreislar specimens of "just" baryte with chalcopyrite are really common, at least here on the German market. But there are not that many good pieces with strontianite, congratulations on a really good German classic!

Thank you, Tobi. Yes, it's not hard to find Dreislar mine specimens of chalcopyrite on baryte even here in the US, but this is the first piece I have seen with a combination of the baryte and strontianite. I was very pleased to find it.

A really nice piece from a wonderful locality!
I think I've seen this specimen before, did you get if from a German dealer named D. Michel? ;-)
Very very nice one!

Thank you, Tobi. I acquired this piece from a U.S. dealer, but minerals often seem to have a way of passing through several dealer's hands before they make their way to a private collection, so maybe it was once in the stock of the German dealer. In any case, I was pleased to find it as I'm trying to expand my mineral suite from Germany.
