A richly crystalized specimen in fine condition collected in 1970 by John Marshall. John notes on his collection card " Found in the north end of the open cut above Driggith Mine on West Fell. Specimens in the south end tested Mimetite but this is deeper green and more Pyromorphite in shape". These crystals are far larger than average and the condition is excellent. Sadly this quality has not been found for decades, John spend many weeks digging in this zone and this was his best specimen. A very fine Driggith piece.
Susanna Mine, Leadhills, South Lanarkshire
7 x 5.2 x 3 CM (cabinet)
Late Summer 2018
An impressive dense mass of small Pyromorphite crystals encrusting all sides of the matrix. From the classic Susanna Mine Leadhills, Scotland, this was in the John Marshall collection. Collected by him in 1970 such fine specimens have not been found for decades, it was the end of an era of richly productive field collecting. In fine condition with a deep green color this is simply an attractive, sparkling specimen from a classic locale.
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.
Choice, quite lustrous green Pyromorphite (originally labeled as Mimetite) from the old locality at Donori, Sardinia. Very good coverage and deep apple green color, a few small crude crystals are seen with strong magnification, but overall this is a botryoidal specimen. Quite three dimensional and in fine condition, this is much richer than most I have seen from the locality. These are now often labelled as being Pyromorphite- Mimetites as it seems there are both species in the deposit and may be zoned.
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.
Resuperferolitica Mine, Santa Eufemia
8 x 6 cm (cabinet)
Ex. John Marshall collection, a very well crystallized Santa Eufemia Pyro with large individual crystals that exceed 1.6 CM. This is overall in excellent condition and is crystallized on 2 sides with large vugs filled with sprays and freestanding individual crystals. A super display piece from a very important locality.
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.
Freihung, Grafenwohr, Upper Palatinate
5.7 x 4.6 x 2.5 CM (cabinet)
An older Bavarian Pyromorphite with very dense coverage collected before 1962. Glassy luster and good sparkle. This locality is now part of a military base and collecting is not possible. Crystals to 4mm cover the face of the sandstone matrix. Good color and transparent crystals in fine condition.
