A mass of rounded Galena is covered on all sides by sharp brown crystals of Pyromorphite. A choice example from Stribro (Mies) in Bohemia, this was in the Bally Museum (Switzerland) then sold by Alain Martaud to the John Marshall Pyro collection. A floater, the crystals are slender like needles growing on all surfaces. By naked eye this is in perfect condition but with magnification some broken crystals are seen. A much better than average old Mies specimen that is probably the Ca rich variety but has not been tested.
Pyromorphite on Cerussite -Classic
Pheonixville, Schuylkill Township, Chester County
6.4 x 5.1 x 2.9 CM (cabinet)
An especially fine old Pheonixville, PA Pyromorphite that forms on the outside of a vug of Cerussite crystals. The vug probably is the cast left by altering Galena, but none is present now. The Pyromorphite has very transparent crystsals on close exam and there is a color range too. Ex Schortmans minerals and John Marshall Pyromorphite collection obtained by him from Thurstons in 1988. In quite fine shape overall, it takes good magnification to find and bruises, by naked eye this is perfect. The Cerussite adds a nice association and the whole thing displays well from several angles.
Wheal Alfred, Phillack
7.3 x 6.5 x 3 CM (cabinet)
Cornish Pyromorphite from the prolific Wheal Alfred. Ex John Marshall and Douglas Creba with labels. Tiny grass green crystals on several sides of a blocky matrix. Wheal Alfred long ago produced a few very fine, world class Pyros which today are prized and very expensive when available. This is frankly not in that league but it is better than average, looks great magnified and a nice locality piece with good coverage.
6.5 x 5 x 1.7 CM (cabinet)
This is a special and odd piece in our series of rare and exotic localities for Pyromorphite. Ex. John Marshall Pyro collection and Larry Conklin, I can find no information about this locality in SW Java, and only one Lead mine in the region but not by this name. John was a dedicated collector and researcher of Pyromorphite, he built an incredible, comprehensive suite including many unique and obscure localities. This piece also has an older German label and many collection numbers affixed, it seems to have been in many previous hands. The crystals are on both sides of a gossan matrix and are unusually dark green nearly black in person. Most are in fine shape but some chipping can be found on close inspection, overall a nice Pyro and exotic.
Pyromorphite -unusual botryoidal form
Manhan (loudville) lead Mine, Southampton, Hampshire County
5.9 x 3.5 x 2.7 CM (cabinet)
A very unusual and oddly attractive old Pyromorphite specimen from the Manhan Lead mine in Massachusetts which is the oldest Lead mine in North America (1679). The matrix is covered on one face with a smooth olive green botryoidal surface of layered Pyro. Ex. John Marshall collection, I have seen this habit a few times before but it is rare at this locality which usually has small bright green to brown crystals. This habit does not even look like a Pyromorphite, but close exam and strong magnification show it is indeed. This specimen is by far the best of this sort I know of, esthetic and in very fine condition.
8.3 x 5.3 x 2.6 CM (cabinet)
From our series of unusual, strange, cool or odd locales for Pyromorphite. A mystery piece since it is unlike any other Mexican Pyromorphite, and with a puzzling (perhaps wrong) locality. Ex John Marshall collection, John obtained this from the Lesnicks mineral dealership in 1992, labeled Sinaloa State, an area not known for Pyro at all. Either this was mislabeled or came from a new find that is since lost. We normally do not handle specimens with uncertain locality details but this is a a quite unusual specimen and very well crystalized so it may be right for someone who wants to do the research The matrix does not match any of the Mexican localities I am familiar with. For the collector of Pyromorphites or Mexican minerals who has everything, or who likes to do the research and get the correct details of this place.
Stribro (Mies), Tachov District, Pizen Region
5.8 x 3.9 2.7 CM (cabinet)
A somewhat "normal" type of Pyromorphite from Stribro Mies. The Calcium rich Pyromorphites from Stribro were at one time proposed as a unique mineral specie "Miesite", but is simply a variety. This vintage specimen has a chain of labels calling this Miesite but it does not have the usual look with brown balls. This is a more normal type Pyro with two generations of greenish to yellow-brown crystals on gossan matrix. A nice old piece ex University of Pennslyvania, Crawford and Noll collections. Crystals to 5mm but most are smaller, in reasonably good condition especially considering the age and delicate nature of the piece.
SOLD Opal - precious opal
stock #SOLD 15.1-137
Carbonera Mine, La Trinidad, Tequisquiapan Municipality
5.1 x 3 x 1.5 CM (small cabinet/ large miniature)
Unusual locality for this sort of opal that looks very Australian. The Carbonara mine in Mexico has produced mostly a reddish "Fire Opal" but small amounts of precious Opal with a milky white base have been found over the years. This piece has quite good fire with red, green, blue and some orange color flashes.
