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 an 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), 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.
Prominent, large well defined Carlsbad twin Orthoclase is pseudomorphed to Topaz. The Topaz is well exposed from the matrix and is 5.8 CM across. The matrix also includes several small Cumberland habit Quartz crystals mostly on the backside of the piece. This is an old piece from a classic German locality, not often available on the mineral market. In fine condition.
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.
Ludlamite with Vivianite
Blackbird Mine, Lemhi County
6.3 x 4.3 x 1.7 CM (cabinet)
The Blackbird mine was a small Cobalt operation that in the 1950-1960s occasionally produced well crystallized Ludlamites. Sometimes with Vivianites, these were by far best of the specie found in the US, and some can be compared to good Bolivian material. This is a good small cabinet with both species in well developed crystals. Very hard to find anything larger than a thumbnail now, this is an early 1960 vintage piece ex Charles Noll collection.
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.
