A really nice specimen, Michael. Nice colour, good contrast and such a beautiful tiny landscape of flawless pyromorphite crystals.
And it reminds me of classic pyromorphites from Germany or England.
Lovely!

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.
