The old mines of Saxony also host a number of type localities also of very rare minerals. My contribution is a picture of a specimen of yellow Xanthiosite on green crystals of Aerugite from Johanngeorgenstadt, Erzgebirge - type and only locality of these extremely rare minerals. (South Terras Mine in Cornwall is listed as another locality and TL for Xanthiosite - but this is a well documented fraud commited by the (in)famous British collector A.W.G.Kingsbury who probably presented a part of a museum specimen from Saxony as coming from Cornwall).
This is an extremely rare specimen - probably part of the type material found in one specimen (Bergmann 1858)and later split between a few museum collections. The pictured specimen in my collection was obtained from the collection of a famous old US dealer and may have come from the US National museum collection.

| Indeed a not that often seen mineral. However, xanthiosite is known from a slag locality near Mansfeld in Saxony-Anhalt.

Hi Jordi,
Sankt Andreasberg is wrong in this thread, it has nothing to do with Saxony and Erzgebirge. It belongs to Harz Mountains 200-250 km away. But in the mineral discription i see ANNAberg (which is a well known Saxon area) - so i suppose you just mixed the two names up ...?

Nice Fluorites!!
It's strange that so many Fluorite from so far away make it to Belgium (US, China, Namibia,Peru,...), but I have yet to see one good German Fluorite on a Belgian show!

That stuff is getting rarer, even on German shows. The classic fluorites from the Saxon mining areas are very sought-after, so it gets harder and harder to find good specimens. Nevertheless i wonder that you never find one at a Belgian show!

P.S. Here are some more impressions of Saxon fluorites from Annaberg District ...

Hi,
the Beihilfe specimen probably was once one of those famous blue ones from the 450 m level, unbenannt Spat vein. Many of them bleached out and got this typical greyish green colour with yellowish parts inside the crystals.
The Sauberg specimen could be from the Prinzler vein (if you need to know this).
Cheers
Andreas
