Even the most German collectors do not know the fluorites from Hühn fluorspar mine, Trusetal, Thuringia.

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).

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. (Author: Andreas Gerstenberg)

If you like Sweet Home mine rhodochrosites you´ll smile at me if I tell you that this is a very good Saxonian rhodochrosite sample. About 6,5 cm consisting of tiny saddle-shaped rhombs. From Alte Hoffnung Gottes mine, Kleinvoigtsberg, Freiberg district, Erzgebirge, Saxony. Rhodochrosite for itself is not that rare in Freiberg, but crystals are. Kleinvoigtsberg and Rothenfurth developed the best ones. Today it´s very hard to find any, this one I got at the Freiberg show in 2009. With two old labels (dating from 1901) - "Dialogit" is an old German name for rhodochrosite (being in use until approx. 1920). (Author: Andreas Gerstenberg)

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. (Author: Andreas Gerstenberg)
