Malachite Ps after Azurite
Flubspatgrube, Lichtenberg, Bad Stben, Franconian Forest, Franconia
5.9 x 3.3 x 2.7 CM (small cabinet/ large miniature)
A fine old Pseudomorph with a very well formed main crystal 2.4 CM tall. From the collection of Thomas Fitzpatrick, this is in excellent condition. I have not seen any other of this quality, the separation and contrast with the matrix is superb. There are some smaller crystals on the matrix most with some damage or are fully broken but these are not very obvious. The matrix is largely a dark red to brown Gossan with a few small Goethite spheres. On the bottom of the matrix there seems to be a small zone of Pseudomalachite as well.
Proustite-classic ruby Silver
Shaft 207, Niederschelm, Schelma, Schlema-Hartenstein District, Erzgebir
1.6 x .7 x .6 CM (thumbnail)
Late Summer 2018
A complex single crystal of bright red Proustite and just a tiny speck of adhering matrix. Classic Ruby-Silver, from the German Erzgebirge, this has very good luster and the red color shows no sign of fading. Close exam with magnification finds some chipping but most of the crystal faces show good form with glassy striations. Much better in person, this is a choice thumbnail at a very reasonable cost for this highly desired Silver mineral.
Cerussite covered by Pyromorphite
Schapbach, Black Forest, (Wolftal)
7.2 x 5.9 x 3.2 CM (cabinet)
Late Summer 2018
Exceptional quality for this less well known locality. The matrix is almost all Cerussite in many crystal forms, with a small area of Galena nearly all covered with tiny Pyromorphite crystals. The matrix also has a dusting of very tiny clear Quartz in doubly terminated crystals that add a lot of sparkle. There are other Phosphate minerals on the specimen that are not identified. The Pyromorphite ranges from pale yellow to green hues and the whole is very colorful. The shapes of some Cerussite twins are well defined but brightly colored by the coating of pyromorphite. This all makes a very fine look under magnification. Ex John Marshall, Heinz Stempel
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.
The Eisieben mines date back to the end of the 19th century (or more), worked for Copper and Nickel, but from time to time some excellent Selenite was found. This is a choice piece, in pristine condition, with sharp delicate prisms on matrix. In person the transparency is far more impressive.
Kransberg, Usinggen, Taunus Mountains
6.8 x 4.9 x 5 CM (cabinet)
An old Kransberg German Pyromorphite from the Collection of John Marshall. Johns Pyromorphite suite was an ambitions attempt to gather the best examples possible from every confirmed Pyromorphite location in the world. He obtained many obscure and exotic examples in 60 plus years of effort. This was obtained by him in 1989. The 6.3 x 4.5 CM display surface is covered with mix of Pyro and Quartz with crystals to 5mm., most in good condition. Although no mine was attributed on older labels it looks a good match for the Jennette mine in Kransberg.
Runderoth, Grunblieberg Mine, Gummersbach, Bergisches Land
8.9 x 6.1 x 4 CM (cabinet)
A cabinet sized Pyromorphite densely covered with dark green crystals in good condition. An older specimen Ex. John Marshall collection of Pyromorphites, obtained by him in 1994 in Munich. The locality given of Runderoth seems to be a specific point in or near the old Grunblieberg (Green lead Mountain) mining area. Nearly all of the matrix shows at least a few Pyros, but the main display face has a 5 CM diameter dense patch of well formed crystals. John was a fanatic collector of Pyros and was on a mission to obtain the best he could find from every locality in the world. He was not able to upgrade from this one during the next 20 years of collecting.
