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.
6.5 x 2.9 x 2.7 CM (cabinet)
From the impressive finds of 2016 this is an nice example of this purple to blue color change Fluorite. The crystals are gem clear (this has been referred to as "Tanzanite Fluorite" due to the deep color) and most show slight wispy zoning or phantoms. The specimen is contacted on the backside and some crystals have a few rough spots so it is not right for a perfectionist but it still displays very well and is much more affordable as a result. The matrix is a duze of small Quartz crystals and the Fluorites are nicely perched on the matrix stalk. The color shift is seen under different light sources, ranging from a grape purple to indigo blue.
Boltwoodite on Calcite
Goanikontes Claim, Goanikontes, Arandis
10 x 8.4 x 5.2 CM (cabinet)
An especially choice large specimen of Boltwoodite on a contrasting dark brown druse of Calcite. Protected by this shallow pocket, the radiating clusters of sharp bright yellow to orange needles are in excellent condition as seen. The radiating areas are about 1 CM across which is larger than typical as well. Special arrangements are needed in shipping or this can be delivered in person at a mineral show. Fine overall esthetics and rich density of Boltwoodite on matrix make this a top specimen for the specie.
Witherite - fine US classic
stock #15.1-1060 CN-2017
Minerva #1 Mine, Cave-in-Rock, Hardin County
8.8 x 6.7 x 4.1 CM (cabinet)
An excellent old time USA Witherite with great form from the Minerva #1 mine. Classic early 1960s vintage. Ex Dufoe and Noll collections, with fat barrel shape crystals showing well stepped striations on the edges. This specimen also has a good light yellow-orange color and is much more attractive than the more usual plain white. Alston Moor in England and the Minerva mine, (all long closed) produced all of the fine Witherites ever found. Fine pieces like this are now only available from older collections and getting very scarce. This is an especially choice piece, has great wet look luster and displays great from several angles.
Fluorite -rare locale
Gyrenspitz, Santis Massif
8.2 x 7. x 4.3 CM (cabinet)
Ex Herbert Obodda, Charles Noll collections. A really nice, unusual Fluorite from a rare Swiss locale. The crystals are modified cubes with beveled edges and some face frosting. Unlike what is usually seen as Swiss Fluorite, the original labels give the locale as "Gyrenspitz, west of Santis". This is a significant landmark but In that location no such Fluorites are known. However the Santis Massif (Alpstein Massif) has produced Fluorite this habit and look in the past. In good condition overall, The blue color is especially strong in direct sunlight.
