One of the mineral world's great classic pseudomorphs are the Hexagonal Pyromorphite crystals from Kautenbach that are replaced by Galena. These are all very old, vintage specimen most having been collected more than 150 years ago. These are also usually quite expensive and not many are seen in thumbnail size. This is a much more affordable specimen than any we have ever seen offered. We must note this is small and not super perfect, there are some edge chips and rough spots but it does show the desirable form and habit of this venerable mine. A good opportunity to have a fair example of this classic for an unusually good price.
A major, important antique German Bournonite in a large single crystal. Certainly not pretty but reputed to be the the biggest known single crystal from this famed locale and possibly the largest single crystal from all of Germany. This is also quite sharp for the size at the locale. Over 6 CM across, this is a flat tabular habit as is typical from the Georg Mine. Rather crude in some areas but very sharp in others, it has a few contacts but overall is quite distinct as seen. The vintage Boubée label dates this to late 1800's to early 1900 era, so collected at least over 100 years ago, likely much older. Some faces show an interesting metallic patina and in person there is a fine "gunmetal" luster in spots.
From the Idar Oberstien area that is famed for its Basalt flow minerals most notably fine Agates. This is a delicate and sharply formed replacment of a flowerlike spray of Glauberite bladed crystals enclosing a vug. All the Glauberite are now replaced by Quartz with the inner part showing a zone of Amethyst fingers. Some fingers show the hollow void where the Glauberite crystals had been. An older specimen ex Ruth Palmer and William Hladysz collections. This is a bit similar to some New Jersey (USA) casts often seen with Prehnite replacing Anhydrite.
Galena Ps. Pyromorphite - classic
Kautenbach, Traben-Trarbach, Hunsruck
7.1 x 6.2 x 4.6 CM (cabinet)
Late Summer 2018
One of the most respected European classics are the Pyromorphites that were pseudomorphed by Galena from Kautenbach. This specimen has very sharp and distinct hexagonal crystals that in some cases are fully pseudomorphed to Galena and a few have a later regrowth of an outer layer of Pyromorphite. The crystals are well exposed and stand up above the matrix. Very clean damage wise, the crystals on this specimen are small but much more distinct than usual from this classic locale. Ex Seaman museum, most specimens of this sort we have handled had larger crystals but also far larger price tags, usually in the 4-8K range. This is a good example of this treasured classic that is affordable but still choice.
Rosenburg Mine, Braubach, Bad Ems District, Lahn Valley
4.2 x 2.3 x 2 CM (miniature)
Worldwide mix summer
A perfect, undamaged small Pyromorphite with a pleasing form from the classic Bad Ems area. A thin plate of matrix crystalized all around with mustard green pyros some of which have a yellow tip. This region is world renowned for the many fine Pyromorphites that it once produced, especially the large brown hoppered crystals. This old piece is of a less common style and color. Remarkable to be 360 degree displayable and completely damage free. One face of the specimen has less green and more typical brown but even that side displays well too. The Rosenburg Mine closed in 1963, and it was most active in the late 19th and early 20th century. Specimens of this quality are usually quite old and have passed through many hands, making it rare to be so pristine.
Cerussite -vintage from classic locale
Freidrichssegagen Mine, Frucht, Bad Ems District
3.2 x 2.6 x 2.3 CM (small miniature/ large thumbnail (toenail))
new june 17
An old, very gemmy Cerussite with several different crystal habits present with label from the mining Acadamy at Freiberg (Bergakademie Freiberg). The Bad Ems area once had many lead mines and was famed for its great Pyromorphites. The Cerussites could also be quite fine as seen here but many old pieces do not have a clear mine atribution. This piece is clearly noted as from the Friedrichsegen mine, which closed in 1913. The condition is excellent.

Choice, classic thumbnail of flesh colored Pyromorphites showing fine Barrel shaped crystal form and hoppered terminations. A small bit of adhering Barite is noted but mostly this is all Pyro. A nice arrangement very three dimensional with good luster. Magnification shows the main crystals are undamaged but areas at the edges have some chipping, not visible by naked eye. A good, affordable German specimen.
A perfect composite crystal with alignment of the individual prisms and spraying out from the origin point. This is a perfect condition specimen with fine wet luster and attractive form on all sides. A vintage Bad Ems specimen that comes with old labels and a glass topped box likely late 19th or early 20th century vintage. It is quite rare to find a crystal this large without chips or issues. A choice classic locale German Pyromorphite.
