Definitely not! And I have to specify my answer having not seen the special crystal form before. Görlitz and Wroclaw are the Museum collections that may have such crystals. There are multifaceted crystals in the collections but not the ones shown by Lasaulx.

Andreas - a specimen from Franz Count von Matuschka collection, how nice for my eyes! ! He was born in Debno near Wolów (Schöneiche bei Wohlau), actually in the heart of Natura 2000 area (and 24km from my place of birth). A member of the noble Silesian family, with the most famous Heinrich Gottfried, Count von Mattuschka - an outstanding botanist, Silesian flora expert and author of 'Flora Silesiaca' (1776-1777). I didn't know that his collection survived the siege of Berlin in 1945? Or this is the only single specimen?

[Andreas Gerstenberg]

This is not the only existing specimen. Some pieces became part of the Berlin Natural History Museum collection. I think, the pucherite is from the same origin. Interesting facts on Matuschka, thank you.

Those are some great barytes you posted, Andreas. Especially the one from Grube St. Johannes is quite exceptional.

I suspect the one you posted from Reicher Spat, Schlettau has the wrong locality, I don't think there were any specimens with this yellow fluorite from this mine. Perhaps you meant Reiche Empfängnis, or one of the other mines in the Frohnau area.

Speaking of old stuff with old labels:

[Andreas Gerstenberg]

Of course you're right there, Niels. My mistake. Reiche Empfängnis mine, Frohnau, Annaberg District is the correct locale.

Thanks Niels!

Another fluorite! Unfortunately, no old labels. Just identified as "Pohla."

[Jesse Fisher]

Another fluorite from Saxony. Previous collection label gives location as "St. Michaelis Mine. Annaberg"

Hello Tobi, From what I can see on Mindat, it looks like "St. Michaelis Mine" is actually a number of different shafts and adits?

[Tobi]

[Jesse Fisher]

Thank you for the translation. I saw that word, but it is often hard to find English translations of German compound nouns. I look up the parts and get "Find Mine." This makes sense! I now have a new word as well as a new specimen.

[Jesse Fisher]

Another nice fluorite twin from Beihilfe. Very much like Weardale twins, but not strongly fluorescent.

In reviewing Am Mizunaka's posting from January 16 2014 (before my time), I believe the "unidentified reddish mineral" is almost certainly sphalerite. Bob
