Here will go some general comments about German Fluorites.

Artenberg quarry, Steinach, Haslach im Kinzigtal, Ortenaukreis, Freiburg Region, Baden-Württemberg, Germany
Quartz-Calcite veins in gneiss rock. This was the best location for large fluorite octahedrons in the whole black forest. Green crystals of up to 10 cm have been found there, sitting on white calcite and looking very very attractive. Smaller crystals in blue and grey were also found, but green was the predominant color. These fluorites also have another nice feature - they fluoresce quite well. Most other black forest fluorites exhibit a rather dull fluorescence. Also a lot of the crystals have a rather "etched" looking surface composed of little fluorite cubes. Other associated minerals were quartz, pyrite, chalcopyrite and other sulfides. Though the quarry is still active there has been no fluorite find for quite some time as the part of the quarry with the fluorite mineralization is currently not in use. When the fluorites were found some local collectors used to claim the best spots and tried to keep other people away - even by threat of violence. Good calcite crystals and some of the associated ore mineralization can still be found. Permission of access is required. Since the "Naturkundemuseum Freiburg" was changed to the "Naturmuseum" and the mineral collection display there was sacrificed almost completely (shame on them) the only place I know to display Artenberg Fluorites is the Minerlienmuseum in Wolfach, near the famous Clara mine.
Teufelsgrund Mine, Belchen, Münstertal, Breisgau-Hochschwarzwald, Freiburg Region, Baden-Württemberg, Germany
Teufelsgrund ("Devils Ground" ) is an abandoned Silver/Fluorite Mine in the southern Black Forest. The mine exploited several mineralized veins, with Schindler vein and Teufelsgrund vein maybe being the most important ones. The oldest record of mining on these veins is from 1512 ! - but carbon dating of a peace of charcoal fould in one of the workings reveled that mining started a lot earlier - the piece was dated to around the year 950. The mine closed in 1958 due to low Fluorite prices. It was reopened as a visitors mine some years ago and is well worth visiting. The Fluorites from this mine are really amazing. Starting with cubes and extra faces on the edges the crystals "transform" to rhombic dodecahedrons, hexoctahedrons to almost spherical structures with 282 faces (see Extra Lapis 4, Fluorite p. 72ff.). Whereas cubic crystals could reach the size of 5 cm and more the more complex crystals are rather small (mms) but make out he special magic of these pieces. Especially water clear hexakis octahedrons growing on marcasite are very famous and can be found in several museum collections. Though these crystals are tiny they can still be found on the old dumps - and is worth digging for them. The larger crystals are quite often pinkish to purple but other colors were also reported. The smaller, water clear crystals mostly have no color at all.
After its closure the mine was the used by mineral collectors to collect very beautiful specimens. This even included the use of explosives - and a really nasty accident happened. Now this is the story how I was told it: Two guys had themselves locked in underground and put some charges in place. As they did not explode as expected one of these guys went to have a look and got hit by the blast. He barely survived and was seriously wounded. Now as they were locked in the only way out was use the rest of the explosives to blast the entrance door open. They made it and the wounded person survived though he lost some fingers and had his eyes damaged. As dealing with explosives and damaging other peoples property is a serious offense these guys also faced criminal charges - but the court showed mercy and the verdict was rather mild.

Fluorite & Pyrite 10cm wide
Grube Anton is a rather rare locality. There is a lot of Tannenboden Mine stuff on the market but very little good material from Anton. This one I bought a few years ago from a local mineral dealer who specialices in buying old collection and selling the better pieces on mineral shows. I now live in Black Forest since 1997, but this is the first good specimen from that mine I was able to get my hands on. The coating with pyrite is a bit unusual for Wieden, but could be confirmed by comparison with similar specimens. A pity these mines are closed now. Imagine all the wonderful specimens that came out there in the 1950s and 60s.

Grube Gottesehre (Urberg) had some really lovely yellow fluorites

If this thread gets revived... I have plenty of black forest material I can photograph and now I also have a much better camera...
It would be a shame if the lovely German fluorites stay as neglected...

Holger,
i would gladly join in but i have to finish german pyromorphites first and also pseudomalachite (which i will try to do so during long winter nights). Some people who wanted to contribute to the german pyros also went quite quiet ;-) .. i am still waiting for the Schauinsland texts and for the Saxony pyro entries. The remaining Rhineland-Palatinate pyros are dealt with quite quickly. If i find time i´ll help with the german fluos of course
Cheers

Rock,
it is my pleasure, here are the pictures of the two Artenberg specimens I have here in Freiburg. The lighter green color is a bit difficult to catch.

Now we need some good close-ups of hexakis octahedrons and such like. I hope I can get some good ones in the near future.

More Fluorites....
one more Fluorite to start for the New Year. Blue Fluorite from the Black Forest Location Fahl (Todtnau). This is a specimen from an old collection where the label is not helpful - just stating Fahl. Most likely this is from St. Anna mine but the information on the mines and veins there is not very good. Still a very beautiful specimen that has a lovely blue color. As these specimens may loose their color if subjected to sunlight I rather keep it in a dark drawer.

one more little thing for tonight
A really nice yellow Fluorite from Leopold Adit in Münstertal. The mine was reopened in 1957 to prospect for Fluorite. Other workings of that mine date back to the middle ages and were at least partially produced by fire setting. Fluorite crystals with an edge length of more than 40 cm were reported, but these crystals are etched on their faces and may not look very nice at all.

as my girlfriend is still busy preparing for her seminar tomorrow... one more thing
Fluorite from Riesenwald Quarry (or maybe the mine next to the quarry), Hinterohlsbach, near Gengenbach - in the central Black Forest. This was one of the first locations I ever visited as a very young man. And did not find much. When I went there 20 years or so later with some local collectors they dug there a lot and found some strangely etched Fluorites. I was not to keen collecting these and just removed some rocks when they were finished and found a nice little vug full of purple cubes. Enough to make my day. Then the locals told me that there is a mine next to the (disused) quarry from there the better fluorites came. They even showed me the the entrance and how to open the gate that locks it. But we had no hard hats and lamps with us so we went home with our lucky findings. The specimen here is from an old Fluorite collection that was sold some years ago. It is described as a "Clara Mine" specimen in the Extra Lapis Fluorite. But the hydromuscovite matrix and the crystals clearly prove that this is from "Ohlsbach". To be sure I also checked this with the author of that article who happens to live just a few hundred meters down the road.

Another nice specimen from the Black Forest: Grey-blue Fluorite from Hesselbach Mine. The mine was recently visited by collectors who found some really good blue and purple-blue Fluorites underground.

Rock,
I don't know if this specimen is worthy but it is from the Frieberg District, Erzgeberge, Saxony, Germany. It came out of an old collection with that locality information. The fluorite is associated with white quartz and is 7cm by 8cm in size.

More Fluorites from Black Forest
This time a rather rare locality: Grube Anton / Wieden. There is a lot of Tannenboden Mine stuff on the market but very little good material from Anton. This one I bought a few years ago from a local mineral dealer who specialices in buying old collection and selling the better pieces on mineral shows. I now live in Black Forest since 1997, but this is the first good specimen from that mine I was able to get my hands on. The coating with pyrite is a bit unusual for Wieden, but could be confirmed by comparison with similar specimens. A pity these mines are closed now. Imagine all the wonderful specimens that came out there in the 1950s and 60s.

One more little thing....
Fluorite from Segen Gottes Mine, Schnellingen. Very good specimen for that location. The mine is an ancient silver mine that was last active in the 18th century and is now a visitors mine. The old men were after silver rich galenite. Unusually for such an old abandoned mine some really good fluorites were found there. The larger crystals are mostly cubes where the smaller ones can show more complex crystal structures, Some minerals were found at the dump in front of the mine entrance, but this one looks definitely like an underground specimen.

this time from Brandenberg Mine, Todtnau. Very good specimen - there were larger ones host most the ones I know are rather grayish. This one, though covered by Quartz, has a nice blue color in daylight - an turns a bit grayish in artificial light. Used a daylight lamp to take that picture. No color enhancement with photoshop !.

Hi all,
Fantastic article, thanks to all contributors.
This is maybe not the right place to post this question but as it is about a German fluorite, I can't be completely wrong either.
Yesterday I posted a specimen I have since 1983 from the Bleihilfe mine.
By looking at other specimens of this kind, I saw that 2 localities are given , the Samuelspat vein or the Isaac Spathgang.
You probably all know that I like very much the exact locality and history of the specimens I collect. So if someone have a better locality than just Bleihilfe or can tell me which one of the veins it comes from, I would greatly appreciate.
Thank you in advance for any comment.
Take care and best regards.
Paul.

One more Black Forest specimen. Fluorite "balls" from Teufelsgrund Mine / Münstertal. The different crystal shapes make this mine one of the most interesting for Fluorite collectors. As this is now a visitors mine there is only old material from the dumps left to search.The smaller Fluorite crystals are mostly hexakisoctahedrons.
