Absolutely amazing specimens.
I'm wondering about the matrix of the Schauinsland image. What exactly is it and what does it consist of?
Even for an amateur I have this obsession for wanting to know everything about everything going back (like stages) to how it was formed.

Okay. That's kinda what I thought and it looks exactly like what I'm mining right now in southeast Colorado. Limonite, quartz, with what looks to be arsenic layered in between.
But this stuff I'm into is carrying a tangerine colored crystal matrix on the surface.
Not sure what it is yet.

So I just realized what this beautiful tangerine crystal I found on host exactly like yours.
Its Orpiment. And I'm putting right back where I found it. Ughh

This is not my favourite Pyromorphite in my collection but it surely is one of the them, but I want to post it because you don't seen too many of these specimen from this locality.

And in addition the color is special.

Size 10*5 cm.

Little Giant Lode (Little Giant Mine; Upper Giant Prospect; Upper Giant Mine), Mullan, Coeur d'Alene District, Shoshone Co., Idaho, USA

A very nice and interesting contribution, Mathias, but I think an overall photo with the whole specimen on it would always be the best way to present larger aesthetic mineral specimens, no need to cut the frame.
