| Grey silver sheets on reddish grey massive hornstein quartz. Very old sample (8 cm in width) from Johanngeorgenstadt, Erzgebirge, Saxony. The mining district of Johanngeorgenstadt is not as well-known as Freiberg or Schneeberg, mineral specimens from there are rare. Famous are the mimetites (type locality) but also good silver minerals were found (notwithstanding you don´t see them that often). With two old labels. |

Thanks, Andreas, for the new pics.
A few comments:
1) I am absolutely delighted by german marcasites. The one you have posted is amazing: a cluster formed by complex crystals. I had heard about german marcasites - I have searched at mindat and asked here-. I managed to buy several excellent pieces from Czech Republic -Bily Dolina, a coal mine-. Polysinthetic twins.
2) I didn't know that the pseudos of feldspar after leucite could also be found in Germany, close to Loucna (Czech Rep.). I have a piece from this last locality as well -pseudos are by far bigger than other leucites-. Interesting.
3) What such a surprise. You have post a gypsum twin that is identical to my pieces -from Galera, Granada, Spain-. As a proof I am posting an example - but I think to have exactly the same crystal, that I will post tomorrow-. I love their whisky colour and transparency, although the piece of the pic has clay inclusions. Sorry for posting it here.
Mineral world is pretty small...
Cheers,
Antonio

Hi, Ed. Some more German fluorites for you (and for the others too). Although I presume that it´s not the quality level you prefer, I hope you get something out of it;-)
| Description: |
| Even the most German collectors do not know the fluorites from Hühn fluorspar mine, Trusetal, Thuringia. In the 1950s in this mine crystals (cubes) were found, deep green and blue in color, measuring up to 5 cm, some on good baryte crystals. They look like the famous Halsbrücke fluorites from the Freiberg district, Saxony. The picture shows a 6 cm sample with pale blue cubes (some with rosé zoning at the edges). |

| Some Austrian localities (as Nassereith, Imst or Bleiberg) are known for wulfenites. However, the wulfies are found on the Bavarian side of the border too. A once famous locality was the Höllental molybdene mine near Garmisch-Partenkirchen. During Second World War the mine was taken up again for a short time. I never saw a real good Höllental sample (not on pictures, not in person...) but it is told that these wulfenites were as good as the Austrian ones from Bleiberg, Carinthia. The only sample I ever saw (thanks to ebay) is now in my collection. I think this specimen is just a reference (crystals up to 5 mm), but it gives a suspicion of the Höllental wulfenite´s quality... but you wouldn´t pick up something like this if it´s labelled with Mexiko or Arizona. |

Hi Andreas, some annotations to your specimens and your comments:
- The baryte from Zobes is very aesthetic. I'm not the the greatest expert concerning barytes, and so even that German locality wasn't really known to me. But this stuff can really compete with Pöhla!
- The same with the one from Piesberg (i didn't even know this place exists ;-)): Never heard of it, but this baryte specimen is really beautiful.
- Concerning the Hühn fluorspar specimen: Unlike my little knowledge of baryte, my knowledge of fluorites is quite good, but you really surprised me with that. I'm one of these German collectors you mentioned who never heard of that fluorspar mine in Thuringia.
- I also like your blue fluorite from Beihilfe mine. I got one of the brownish/greenish specimens from that mine, but i would like to have also a blue one. So if you want to give it away one day, please contact me. You got two specimens from me, so why not turning the tables? ;-)
- At first sight i took your realgar for a Callenberg crocoite, before i read what it was. Nevertheless a great example of another mineral for which our country isn't really known for.
- I think you know that Steinperf and Hartenrod are next to Marburg, so the green sphalerite is quite famous here and the museum owns some extraordinary samples of it. Congratulations to own one!
Go on!!!

| Description: |
| From a 2005 find occur these undamaged brown baryte crystals (6 cm sample). Found at 318 shaft, Antonsthal, Erzgebirge, Saxony. The find developed lots of nearly colorless to yellowish brown crystals which are often damaged, unfortunately. Undamaged specimens are rather rare. |

Oh, what an honour;-) But I think there are much more good threads on FMF with specimens and pictures having a better quality than mine. However, I´ll do my best showing some interesting stuff. So, let´s do you a favour and upload the next 24 pics;-)

| Description: |
| Nearly 5 cm long wires of so-called "Schlotsilber" (chimney silver) from Schlema mining district, Erzgebirge, Saxony. Not all dubious silver samples without matrix are manmade in a narrower sense. Some of them have been found when the chimneys of the smelters (f.e. at Freiberg and Schlema-Schneeberg district, Erzgebirge, Saxony) got pulled down. The silver sublimated on the inside of the chimneys. It is told that big chimney fragments fully overgrown by large silver wires have been found... But there´s nothing about ever been published and actually I never saw such "matrix chimney silver". Moreover you don´t see such loose wires that often; characteristic is their luster - the shown sample is, I think, 50 years old and there is no black tarnish on. |

| The copper shist district Mansfeld-Eisleben-Sangerhausen (Saxony-Anhalt) is - among other things - famous for its gypsum specimens. Most collectors know the colorless and grey crystals from Eisleben. From Sangerhausen (Thomas Müntzer shaft) brown elongated crystals are frequent. A certain variety are "Weißkopfgipse" (white-headed gypsum) from that locality - black crystals with colorless tops. There are big samples with crystals standing closely packed: a feast for the eyes! |

| Pinite - a pseudo of muscovite after cordierite crystals from the original locality, the Pini Stolln, between Aue and Schneeberg, Erzgebirge, Saxony. The mineral was named after Father Pini, the man who described the "Baveno twins" (microcline) from Baveno, Italy. One day a miner found these twins in a tunnel near Schneeberg. In donation of Father Pini this tunnel was named Pini Stolln. Below the number label you can see a Baveno twin in the granite matrix. In fact one of my collection highlights! |
