6.8 x 4.7 x 1.7 CM (cabinet)
An old specimen from the classic mines of Pribram, densely covered with Valentinite crystals. The Valentinites are of the elongated type with complex cross section. These crystals reach 1 CM and are both free standing and flat laying. There are several complete, undamaged crystals but there are also several with clearly visible damage. While this is not a piece or perfectionsts it is better than typical for this delicate mineral and is a lower cost, classic specimen. Ex Vrazel collection.
A fine thumbnail of Anglesite showing the entire crystal form perched on a sliver of matrix, from Tsumeb.
This habit of Anglesite with the zoned dark inclusions is distinctive. In fine condition, no damage can be found even at 20X magnification. One end of the crystal has both Pyrite and Galena in small crystals and masses on the exterior faces, the other end is uncoated except for some micro Cerussites (white) not seen without good magnification. There are dark inclusions of what is most likely Galena seen at several places but mostly near the terminations as dark zones. The matrix here is mostly a druse of small Anglesites that are black, lustrous and thickly included with Sulfides. A choice Tsumeb piece and a nice Anglesite.
Delicate sprays of glassy, transparent and sharp Pyromorphite crystals covering all sides of this specimen from Daoping. Minimal matrix, this Pyro has unusual pale colors mixed with a few of the more typical bright green hues. In impressive condition overall, this is incredible for such a delicate specimen. The pointed light yellow to brown crystasls are arranged in radiating clusters and bunches. The Daoping mine at Yangshao has become world famed for top Pyromorphites. This is a fine quality specimen and it is much more rare to see this color and habit so well presented.
Little Giant Mine, Mullan, Coeur d' Arlene District, Shoshone County
9 x 7.1 x 4.2 CM (cabinet)
A very fine specimen from another uncommon but significant US locality. From the Little Giant mine, at Mullen, Idaho a sizable and rich specimen densely covered on the front surface with pale green crystals. From John Marshals superb collection of world wide Pyromorphite his collection card reads "typical habit on Little Giant piece, about the best I have ever seen." The little Giant mine was an important locale for Pyro long before the Kellogg/ Bunker Hill Mine find put Idaho in the spotlight. The mine closed over 100 years ago and fine specimens are quite scarce. This one is just exceptional, in remarkable condition the crystals are the delicate "porcelain" luster and up to 7mm long. Very different look from the more available Bunker Hill material. Great addition for any serious Pyromorphite suite.
Pyromorphite with minor Wulfenite
Chester County Mine, Pheonixville, Chester County
5.8 x 5 x 4.3 CM (cabinet)
A nice Pyromorphite from the less well known Chester County mine (Pheonixville PA). Ex John Marshall Pyromorphite collection. Johns collection card notes '"obtained by trade with Dana Jewell who dug this out a few feet from me in the fall of 1972." Amid the small olive green crystals are tiny bright red Wulfenites. Some green ball-like areas are also seen that is likely another habit of Pyromorphite but could also be a Mimetite. This locality, like all the others in the area has been closed for many years. I have seen
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.
