A large part of this Land, on the border with the Czech Republic, is covered by the Erzgebirge, which is German for “Ore Mountains”; a name that doesn’t need further explanation. Together with the Harz Mountains in the central north and the Black Forest in the southwest, these mountains were the most important mining region in German history. Legendary wire silvers, different lead and silver ores and once giant deposits of wonderful fluorites in all colors are only a few examples of the many minerals that once came from there. Besides the treasure chambers of that mountains, Saxony also features the famous Schneckenstein Rock – Europe’s only source for really fine gemmy topaz.

There are other European topaz occurences that gave gemmy material (even in Germany), think of the Ural mountains. The Schneckenstein is, however, the best known German locality. Saxony i would consider the mother country of mineralogy.

Here is another photo of the Schneckenstein topaz, along with an old label that came with it. Can anyone give any information about the dealer or collector who's label this was?

"The famous mining academy in Freiberg, Germany was founded in November 1765 by Prince Xavier of Kursachsen, and its mineral museum was founded at the same time, probably based initially on the collection formed by C.E. Gellert (1713-1795). In 1767 the Academy established its own mineral dealership (Niederlage), probably for the purpose of supplying students with study specimens for their own collections. It eventually expanded to supply specimens and geological/mineralogical equipment to schools, students and collectors throughout Germany, Europe and America, advertising minerals, ores, rocks and fossils, in large collections and as individual specimens." - W. E. Wilson (2012)

Thank you. With my admittedly rudimentary understanding of German, I thought "niederlage" meant "defeat," which makes little sense in the context of a mineral label.

Hi Jesse, don't worry about what you know about German language: "Niederlage" IS also the word for defeat (but once was used for a company's store, too).

Hi,
the mine was named Pöhla too. Sometimes you may see the expression "Wismutschacht". Pöhla was an uranium mine and "Wismut" the mining company, said in general parlance.
Cheers
Andreas

The Sauberg mine near Ehrenfriedersdorf is one of the best-known Saxonian mines. Ehrenfriedersdorf is a very old tin mining district - so it´s not surprising that the locality is famous for cassiterite crystals. Other minerals worth mentioning are colourful apatites, good fluorite specimens, wolframite and quartz crystals as well as some rare minerals like herderite (type locality). The silver minerals are the treasures of every local collection but never reached the quality of the Freiberg or Schlema/Schneeberg specimens. Attached some samples from Sauberg mine which are all no museum specimens but some of those are rarely shown.

A Saxonian region that is - let me put it this way - not that famous beyond the German borders is Upper Lusatia (Oberlausitz). It´s the north-eastern part of Saxony between Dresden and Brandenburg, known cities are Bautzen, Görlitz; Hoyerswerda and Radeberg (think of the beer...).
Fine smoky quartzes as well as feldspar crystals, rare fluorites, Be- and REE-minerals come from the Königshain granite quarries near Görlitz, the Pansberg quarry near Horscha is a locality for good variscites and wavellites, the Klunst quarry near Ebersbach gave zeolite minerals, nice epidote and calcite crystals. Two other places that should be mentioned are the Ossling quarry near Hoyerswerda (big, clear rock crystals, anatase, titanite) and the nickel mine near Sohland (pentlandite).
All Upper Lusatian localities don´t play a big role in the mineral world but things like 6 cm molybdenite crystals from Königshain are not bad at all, i´d say. Here are some samples from my collection:

Rarities with their type locality in Saxony: chapmanite and emplectite. Both minerals occured only once more after the type discovery, emplectite in the 1980s in a few micromount samples and chapmanite in a single cabinet piece in 2002. Here are two oldtimers:

The pyromorphite from Zschopau was already shown before, here´s another classic from there - the so-called "Blaubleierz". Zschopau was one of the first known occurences of this always sought-after pseudomorphs. This old sample comes from the collection of Fritz Seliger who served as a prospector for the last German emperor.
