Tsaregorodtsevite on Quartz from Yaruta Mt, Man'-Khambo Mts, Polar Urals, Tyumenskaya Oblast, Siberia, Russia (TYPE and ONLY LOCALITY) [db_pics/pics/rare08-2-06c.jpg]

At 7.5 mm, the larger crystal here is at the maximal size for the species. Tsaregorodtsevite is a VERY STRANGE mineral that is made up of AMMONIA with nitrogen, and an aluminosilicate compound. I recall when Fersman Museum started selling their extras in 1991, this was one of the most coveted of all rare species that came out the doors from their various expeditions. I got some directly at the time from curator Dmitriy Belakovskiy, who has himself been to this remote location on at least one expedition. I assume this specimen came form the same source, the only source so far as I know. In fact, I bought this piece from him at Tucson 2008, surprised to see another turn up after so long. The perch on a quartz cluster makes the display here particularly good - usually these are on flat gray rocks. (TYPE and ONLY LOCALITY)

Bismuth on Quartz from (probably St. Ives, Consols,) Cornwall, England [db_pics/pics/rare08-2-18d.jpg]

An extreme Cornish rarity!!! Crystallized bismuth is known from a VERY few finds here, all from the 1800s. I have seen only 2 of them for sale in 20 years , and this is a fine and aesthetic piece in its own right, showing off sharp crystals to 2 cm right on the front. They are perched on quartz, as you can see from the side shot. So overall, its an exemplary display miniature of crystallized bismuth for any locale, but particularly worthy from the UK. ex. Russell Jones Collection

Hessite on Quartz from Botes, Alba County, Romania [db_pics/pics/rare08-2-86d.jpg]

This is an incredibly rich hessite specimen with crystal sharpness, lustre, and a surprisingly rich coverage o quartz that you almost never see for this rare species. It really is MUCH more showy than the average hessite (and even those are quite rare), which usually has gray lumps on a gray rock. The combination of the vertical stackign and the white quartz flanking the crystals makes these leap out 3-dimensionally, and as you can see the crystals are in excellent condition, not worn and abraded, despite their age. Most hessites of this style were found in the early to mid 1800s in this important mining district. The provenance here goes back to Julius Böhm, one of the most important of the early Viennese mineral dealers (in the late 1800s). Later it went to a collecttor named Tschermak and then to noted dealer Lazard Cahn , circa 1915, by his label. It was almost certainly mined earlier, however. At some time in the 1970s, it entered the Los Angeles County Museum of Natural History on loan for a display exhibit, before finally finding rest in another Musuem (details to owner). I obtained this in trade from collector George Elling, recently. I think the price is extremely fair compared to specimens of far inferior quality, but larger in size, that I have seen from some old collections come up for sale in Munich recently.

A beautiful, good-sized specimen with sharp pink rhombs of smithsonite to 8mm. This is an old classic smithsonite from Tsumeb. The smithsonite crystals are covering bright orange crystals of quartz to 2mm - an association I had not sene previously. Several damaged smithsonite crystals are present on the specimen but overall its in pretty good shape and nothing visually detracts. Its better in person because the quartz adds a colorful accent which has more appeal in person. Piece comes with old Conklin and Hauck labels.

I LOVE THESE THINGS! WHAT A NEAT EXAMPLE OF INTERESTING MINERALOGY, having talc replace a hard mineral like quartz !?!This is an incredibly rare pseudomorph of talc after quartz on massive talc from Germany. These pseudomorphs are quite old, having come out of the ground prior to the 1930s. Unique to this location, the crystals are very sharp and have a soft vitreous luster. One of the hardest pseudomorphs to find in any condition and this piece is nearly perfect, AND OF LARGE SIZE. As you can imagine, this is a "must have" for any pseudomorph collector. Ex. P. Pohndorf collection (1931). E. Mitchell Gunnell and Hauck labels included with piece.

World class epidote specimens have been found in only a couple of places, and in the U.S. this location is Price of Wales Island, Alaska. This location has produced outstanding collector specimens for over a hundred years. This specimen is a fine example of an epidote from this historical location. Having come from the Washington Roebling collection , this piece came out prior to the mid-1920’s. This specimen consists of a very sharp single deep green crystal with minor amounts of quartz. The crystal is doubly terminated and has a highly polished luster. The quartz crystals are milky-translucent and are ALSO terminated. Great classic example of the finest U.S. epidotes, and with a wonderful pedigree! Ex. Roebling and Smithsonian collections.

This is one of those esoteric mineral specimens that defy logic. How can the softest mineral known totally replace one of the hardest? Nevertheless, this is a superb example of talc after quartz, from the classic and only locality we have seen it. These date to the 1800s and have long been staples in any fine european collection. Today, they are almost unavailable and rarely seen for sale anywhere. To me, they are one of the most desirable of all pseudos for the intellectual and historical value of the specimens. What were once clearly well formed, quartz crystals, to 2.5 cm in length, have been totally altered by tan colored talc. The large crystal here of about an inch is large for the occurrence and is the largest I have seen for sale in some time. The label indicates an early 1900s sale by Ward's.

The defunct Bingham open pit, a huge disseminated deposit, was never known for crystallized specimens. Therefore, this specimen of bright, dark gray, tetrahedrite crystals, to .3 cm across, nestled among colorless, lustrous, translucent quartz crystals, to .7 cm in length, is a rare specimen!

This absolutely superb specimen features a large, rounded, flattened, rhomb of colorless calcite, 6.0 cm across, aesthetically perched on a matrix of pastel, lilac amethyst, to .5 cm across.

This specimen, probably from the old Christy location at Magnet Cove, features a quartz rich vug, with colorless quartz crystals, to 1.5 cm in length, upon which are perched two, equant, black, brookite crystals, with astonishing luster. The brookite crystals measure 1.2 cm across. Very nice!

What was once a flower-like, cluster of glauberite, is now quartz. The original glauberite has disappeared, leaving just a hollow shell. The largest crystal is 2.0 cm in length. Fascinating!

Some minor damage present as you can see in pics. This is an excellent example of what used to be , from Butte.
