from the TUCSON and MUNICH shows
Scainiite is a VERY rare lead-antimony sulfide. The mineral was known only in a few, poor specimens from this locality until recently (I am told these were collected in 2009), as you can see from the few photos of smears on a rock, shown on MINDAT. Even at its type locality, 3 mm crystals would be considered large. Here you have, however, 7 cm-long carpet of flatlaying crystals on matrix. They are embedded, and grown in aggregate, but still are huge examples of the species and this is one of the more rich specimens recovered.

This is a MAJOR annabergite specimen with huge crystal clusters to nearly 1 cm, associated with translucent green cuprian smithsonite. Annabergite occurs at its best from this locality, though great specimens are few and far between, despite hundreds of years of collecting. For overall richness, crystal size, and exceptional crystal definition, this is an important and attractive specimen. I have not had a better one, in several decades of dealing in colorful European classics, for what its worth.

A glistening specimen with not only intense color and coverage, but also the BEST natural, wet-looking, caramel-like lustre to the crystals that this mine ever produced. It is nearly pristine, throughout. The appeal of the form, the thick blanket of crystals on matrix, and the color/lustre combination makes it a striking example for classic old Lamentos wulfenite without breaking the bank. The horizon is complete all around, very 3-dimensional and appealing, without the usual broken edges on this material
ex. Lawrence Conklin
A superb, elegant, complete-all-around specimen, with minute rosasite crystals (and perhaps a few dioptase as well), sprinkling over calcite stalactites. It is a unique, colorful, geometrically interesting thumbnail specimen. From the private collection of longtime dealer Lawrence Conklin, a superb thumbnail
ex. John Ydren
SHARP, intensely colorful crystals to about 3 mm cover this matrix plate and make for a very attractive and significant example of the species for this locale. Although you get larger libethenite from other places, the lustre and sharpness of these crystals is, for me, among the top for the species. They look like little green metallic octohedra at first glance. From the John Ydren collection, purchased for $125 in 1972 (a lot of money for those days!). Again, while you can get bigger crystals, this to me has more flash and color appeal than most, and overall is a superb example of the species. NOTE THIS SPECIMEN IS FEATURED IN THE OCTOBER 2010 ISSUE OF LAPIS, PAGE 9, ON THE COLUMN ABOUT "STECKBRIEF: LIBETHENITE"
An unusual specimen of a style I have not seen since the 1980s, this is so-called "angle-plated quartz" in which the quartz has filled seams and preserved the gaps between some other mineral species' crystals. It is a weird thing, in perso, and I cannot recall anybody ever giving me a solid explanation of how these form beyond guesses as to what mineral replacement or mineral cavity they were filling. This is an excellent specimen with dramatic form, and good size, and clean stark white color. It has a sugary sparkle to it from a coating of microcrystallized quartz atop the larger gridwork.
ex. Irv Brown
This beautiful miniature specimen features a GEMMY 1.7 cm crystal atop, which is of quite rare size for the species. More than that, it will literally cut a large stone, again a rarity for the species. This was in the Irv Brown miniatures collection in San Diego, in the mid 1990s, and was then sold as he switched from miniatures to larger specimens. At the time, I recall that the local gem cutter (aka Mark the Butcher of Good Crystals) offered him $1200 for the piece as (wholesale) cutting rough. Irv and I were both mortified! But, that speaks to the rarity of cut gems of this incredibly intense purple color, of any species. Funny enough, I had forgotten about the piece for over a decade and just came across it , to reacquire it, recently. I recognized it immediately of course, as there is so much mediocrity available for these old finds (mostly came out over 30 years ago), and this one was exceptional.
ex. Bart Cannon
This is a ridiculously large euchroite crystal that perhaps is the largest American example of the species, according to some who I have shown it to. I have not heard of or seen any larger ones. It was collected by Bart Cannon, a well known collector of NE US minerals, in the 1970s and traded out of his collection sometime after. It is a unique, deep , vivid blue color that is hard to describe, but not similar to the euchroite from Europe in color or crystal form, by ay stretch. The piece is repaired in the middle and the photos show it at its worst, head-on right at the line of repair, to be honest about it. However when you look at it on a shelf, from an angle up or down, you do not see this crack as much. Now, it COULD be made into a truly incredible thumbnail specimen simply by undoing the repair. The result would be an arrowhead-shaped thumbnail crystal of 2 cm tall, 2 cm wide, and 4mm thickness. The lustre, and color, and habit, all make it leap out. It would be a world class thumbnail (without the repair) and in any case is a major US specimen in either size category. If it doesn't sell, I think I will have to donate to the Smithsonian as its the kind of rock that belongs there.
Crystals of sharp, lustrous, complex galena cover a matrix of quartz and are associated here with the desirable brown, tranclucent siderite that is classic for this old historic locality. The galenas are typical Neudorf style, extremely lustrous with sharp terminal faces and complex sides, sometimes in elongated crystals, here to 4 cm. This MAJOR German galena specimen was purchased by a prominent German collector from American dealer Rick Smith in 1970. This was the same era in which he was trading many old specimens out of the American Museum collections, and in any case it is certainly from an old source as this habit and style is characteristic of the most sought-after Neudorf specimens, from the mid to late 1800s. Such large, robust specimens are very hard to find today on the market. They ONLY come from major old collections, and the occasional museum deaccession. The piece is in remarkable condition with only trivial and peripheral edge wear, and one area near the bottom of broken galena (although it may simply be contacting and not true damage there as parts of that irregular area look crystallized on a micro scale). Even so, I have seen few CABINET sized examples of any quality; and we regard this as a major specimen.
