Nice thumbnail intersecting silver gray metallic platy crystals
Seikoshi Mine, Toi-cho, Shizuoka Prefecture, Honshu Island, Japan
Thumbnail, 1.25 x 0.75 x 0.75 cm
Nice thumbnail of intersecting silver-gray, metallic, platy crystals of pearceite accented by <0.5mm, gray, metallic, cubo-octahedral crystals of argentite (acanthite) from a unique locality. Mineralogical Research Company and two other labels accompany the piece.
Sometimes simply appreciate ve got This thumbnail cluster subhedral
Wolfach, Black Forest, Baden-W_rttemberg, Germany
Thumbnail, 1.9 x 1.9 x 1.3 cm
Sometimes you simply have to appreciate what you've got. This thumbnail cluster of subhedral Acanthite crystals is gray-black in color with a matte to metallic luster. The surfaces appear etched or partially complete, with small vesicles throughout. What actually makes this fascinating is that every photo I can find of Acanthite from Wolfach shows the Acanthite as micro needles, with none anywhere close to this size. While that isn't a guarantee, that certainly creates a certain amount of interest, with a hint that this may indeed be exceptional for the locality. From an old collection, and without old labels, one can only believe what is passed on about such rare provenance. It certainly LOOKS unusual.
A VERY important old historic classic This specimen hosts beautiful
Giovanni Bonu mine, Sarrabus, San Vito, Cagliari Province, Sardinia, Italy
Cabinet, 9.7 x 7.5 x 6.4 cm
A VERY important old historic classic! This specimen hosts a beautiful combination of Acanthite and fluorescent Calcite from the Giovanni Bonu mine in Sardinia. The dark grey, matte Acanthites range up to 7-8 mm, and can be quite sharp in their habit. The lustrous, gemmy Calcites, which form a rich coating on the matrix, average about 1 mm in size, and they have deep orange fluorescence. Included are fascinating hand-written, old time labels, including the label from the University of Naples. Not elegant, but very beautiful for what it is, and a large and fine specimen for the region. I am told this dates to the early to mid 1800s.
The photos say dramatic sculptural specimens I seen period It
Fresnillo de Gonzalez Echeverria (Fresnillo), Mun. de Fresnillo, Zacatecas, Mexico
Miniature, 3.7 x 2.1 x 1.8 cm
The photos say it all - this is one of the most dramatic, sculptural specimens I have ever seen, period. It has incredible, ballet-dancer-like form and a high luster. It is complete all around and perfect. I am told this was from a recent find at the end of 2013 and it was one of only 2 pieces I saw at Tucson 2014, but I simply cannot verify this. I fell in love with it immediately. The price is admittedly not a bargain, but the quality of this thing is unbelievable. Nobody in my office has ever seen the like. Joe Budd photos.
This piece surely old major classic European silver specimen Hefty 283
Freiberg, Saxony, Germany
Small Cabinet, 5.3 x 4.8 x 3.9 cm
This piece, surely very old, is a major classic European silver specimen. Hefty at 283 grams, it hosts a massive cubic crystal of acanthite that is 4 cm on longest edge and in a cluster with other sharp cubes. Technically, this is acanthite ps. argentite according to some people (based on crystal shape), though often they are just labeled as acanthite. From the Eric Asselborn collection. Complete all around, 360 degrees. Joe Budd photos.
Probably dating 1800 s old time plate slightly rounded Stephanite
Schemnitz, Banska Stiavnica Co., Banska Bystrica Region, Slovakia
Miniature, 5.2 x 3.2 x 2.2 cm
Probably dating back to the 1800's, this old-time plate of slightly rounded Stephanite crystals is quite rich and showy for the locale. The grey crystals have a small bit of iridescence, and the visible crystal edges add character and detail. The largest crystal is 1.1 cm, and the half-dozen crystals make a nice grouping on the matrix. Perhaps not elegant, these silver minerals have an aesthetic all their own. A very good miniature. Fioravanti obtained this from the legendary British collected Richard Barstow in 1974.
I purchased specimen directly Mexican miner Tucson It amazing totally
San Carlos Vein, Proano Mine, Fresnillo District, Zacatecas, Mexico
Cabinet, 10.3 x 7.5 x 6.5 cm
I purchased this specimen directly from a Mexican miner at Tucson. It is an amazing and totally unique (in my experience) blend of melted-looking acanthite crystals overlaying huge, robust polybasite crystals. The acanthites are smooth and look more like modern art, than the normal kind of acanthite crystallization we expect from here. It has crystals all around! Other than some contacting on the sides and bottom, it is mostly crystallized all around (with acanthite), although the polybasite matrix itself has some crystals that are not complete.

This unusual antique silver specimen coating acanthite silver wires It
Himmelsfurst Mine, Freiberg, Erzgebirge, Saxony, Germany
Small Cabinet, 6 x 4 x 3 cm
This is a very unusual antique silver specimen with a coating of acanthite on the silver wires, it seems. It is a display-quality small cabinet piece, from the famous Himmelsfurst Mine in Germany. Many of the attractive, curving wires are over 3 cm in length, and their sinuous form as they twist and turn above the matrix is quite aesthetic. Little calcites add accent. A desirable display piece, complete all around, AND an important old classic! Obtained in trade from Ed David in the 1990s, and then long in the Obodda collection. The label for this piece is from Ernst Julius Fröbe, a mining director from Schwarzenberg/Erzgebirge. This man worked as an administrator of many famous mines such as Gelbe Birke near Schwarzenberg. Further more he was an uncle of the famous German actor Gerd Fröbe. E.J. Fröbe died in 1921, and part of his collection turned up in Saxony some years ago.
Front robust sharply crystallized cubic acanthite cluster shown It fat
Rayas Mine, Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico
Miniature, 3.4 x 3.2 x 1.7 cm
Front and back of this robust, sharply crystallized, cubic acanthite cluster are shown. It is a fat miniature with a classic arrangement of intergrown cubic crystals in a Christmas-tree-like arrangement. Complete all around! This is a fabulous example in the miniature size range, without breaking the bank. Joe Budd Photos.

Showing off the sharp octahedral form of the original argentite, this acanthite pseudomorph has fine form and super metallic luster. The crystal is as sharp as a spear head, which it greatly resembles. Complete all around, lustrous, and Very showy!
A complete floater clustered pagoda like 3 cm tall central crystal
Imiter Mine, Atlas Mountains, Quarzazate Province, Morocco
Miniature, 4.6 x 3.3 x 3.1 cm
A complete floater clustered around a pagoda-like 3-cm-tall central crystal, with no visible point of attachment, this specimen of acanthite after argentite is just incredible. It has luster, for starters. Most of the octahedral, splendent, dark gray crystals, to 1.25 cm in length, have grown on top of each other, making the specimen look very much like a cityscape of Chinese pagodas or of South African hausmannite which you could easily mistake this for (though it would be about the best imaginable hausmannite quality!). Aesthetic and mesmerizing full miniature specimen, from this new find.
This specimen octahedral splendent jet black acanthite argentite
Imiter Mine, Atlas Mountains, Quarzazate Province, Morocco
Small Cabinet, 6.0 x 3.8 x 2.4 cm
This specimen of octahedral, splendent, jet-black acanthite after argentite, has individual elongated octohedral crystals to 3.5 cm in length shooting from a central cluster. The overall effect is that of a Chinese pagoda, with most of the crystals on top of each other. This new find has luster - bright sparkling luster that is hard to convey in photos and quite another world from the appearance of previous finds here. It is nearly a complete floater with no visible point of attachment, with only a small rough area near the base; which as a bonus, is a vug at the lower right edge filled with a druse of cherry red proustite. Complete all around, elegantly vertical, this is a superb acanthite by any standard from any other locality.
This specimen acanthite argentite features series stacked octahedral
Imiter Mine, Atlas Mountains, Quarzazate Province, Morocco
Small Cabinet, 6.1 x 4.6 x 4.3 cm
This specimen of acanthite after argentite features a series of stacked, octahedral, splendent, jet-black crystals, to 1.8 cm in length. the crystals literally leap out from a matrix of calcite, silver ore, and massive acanthite (few specimens have any matrix, here). This new find has luster - bright sparkling luster that is hard to convey in photos and quite another world from the appearance of previous finds here. I particularly like the angled group at the top of the specimen, which features a birdlike crystal cluster of 2.4 cm atop. This is a superb, elegant acanthite by any standard, quite different from Mexican and Chinese and German acanthites we might have seen previously.
A stunning miniature This acanthite replacement argentite highlighted
Imiter Mine, Atlas Mountains, Quarzazate Province, Morocco
Miniature, 5.3 x 4.2 x 2.2 cm
A stunning miniature! This acanthite replacement after argentite is highlighted by the two crystals at the apex of the specimen. The one on the right is doubly terminated and measures 1.5 cm in length. The one on the left has unusually curved edges and measures 1.8 cm in length - very strange crystal, that is mesmerizing! All the crystals are octahedral, with splendent luster and a jet-black color that is hard to convey because it is lustrous. This is a superb, elegant acanthite by any standard, quite different from Mexican and Chinese and German acanthites we might have seen previously
This specimen acanthite argentite features splendent dark gray
Imiter Mine, Atlas Mountains, Quarzazate Province, Morocco
Miniature, 3 x 2.5 x 2 cm
This specimen of acanthite after argentite features two splendent, dark gray, stretched octahedral crystals, to 2.5 cm in length. The larger crystal is doubly terminated with slightly curved crystal edges. It is complete all around, has wet luster (much better in person!), and is SHARP. An aesthetic competition quality small miniature or toenail!
Almost complete floater acanthite specimen displayed equal effect It 3
Rayas Mine, Guanajuato, Mexico
Miniature, 4.8 x 4.5 x 2.3 cm
Almost a complete floater, this acanthite specimen can be displayed on either side to equal effect. It is very 3-dimensional and treelike, and just sharper than most acanthites from here tend to be. The dark gray crystals are arborescent, with a few exhibiting incipient, hopper growth. The largest crystal is 1.1 cm in length. Some crystals have a thin coating of brassy yellow chalcopyrite, as well as the base of the cluster. Any way one views this specimen, it is really a fine example for the size and locale! MUCH BETTER IN PERSON. Comes with custom lucite base already made for the specimen.
A razor sharp floater crystal complete finely formed sides It looks
Guanajuato, Mexico
Miniature, 4.6 x 1.7 x 1.0 cm
A razor-sharp, floater crystal that is complete and finely formed on both sides. It looks good from any view, upside down and vice versa! This is classic old-style Guanajuato material with fine luster, seldom seen today.
This important specimen Rayas acanthite notable crystal size robust
Rayas Mine, Guanajuato, Mexico
Small Cabinet, 6.2 x 3.8 x 3.1 cm
This is an important specimen of Rayas acanthite for the notable crystal size and robust crystal habit. It is complete and pristine all around, actually a floater specimen. The hoppered, in-drawn faces add depth and visual interest to the normally more simple crystal habit of these acanthites. This is one of the largest single crystals, not in cluster, that I am aware of, for the locale. This is a crystal that can be stood vertically and exceeds 6 cm height, but set flat and still display as a large miniature. In person it has a bright and shiny luster, and is not "black." Ex University of Arizona collection, by donation in the past.
Acanthite Mexican locales seldom occurs large crystals matrix Here
San Juan de Rayas Mine, Guanajuato, Guanajuato, Mexico
Small Cabinet, 6.4 x 3.3 x 3.0 cm
Acanthite from the Mexican locales seldom occurs as large crystals on matrix. Here, however, we have a sharp, elongated crystal showing intricate hoppered faces, perched aesthetically on contrasting matrix. It is a superb display quality specimen, complete all around 360 degrees. Note the subtle rainbow iridescence in some faces and angles, indicating that the piece has NOT been cleaned in the usual acids and chemicals to "brighten" the acanthite and make it silvery. One can always go buy an acanthite from Mexico, sure; but this one is something special. Ex Kenneth Raab collection to Stoudt in 2002. Joe Budd photos.

San Luis Mine, Fresnillo, Zacatacas, Mexico
Thumbnail, 2.5 x 2.3 x 2.3 cm
This magnificent acanthite crystal is perched on a stem of more slender acanthite. It has brilliant luster, great form and a dark metallic color, and measures a whopping 2.2 cm across. It is absolutely a world-class thumbnail and a superb competition quality specimen of the species.
A gorgeous lustrous complex crystal cluster acanthite forming
Chanarcillo, Chile
Miniature, 3.5 x 3.4 x 2.5 cm
A gorgeous, lustrous, complex crystal cluster of acanthite forming a machinelike aggregate. It is complete all around! This historic specimen would have come out in the late 1800s or early 1900s. It comes with an old Scalisi Collection label, noting it is from the Freiberg Museum. Superb, old classic!

Fresnillo, Zacatecas, Mexico
Thumbnail, 2.9 x 1.8 x 1.1 cm
Stacked crystals, to 8 mm across, of splendent, dark gray acanthite, are aesthetically perched on a stem of acanthite. The acanthite crystals are superbly lustrous, making this a really fine thumbnail specimen with classic form and style for the material from this mine
A remarkable old specimen famous Cobalt mines large flat laying
Langis Mine, Casey Township, Cobalt Area, Ontario, Canada
Cabinet, 14 x 8 x 3 cm
A remarkable old specimen from the famous Cobalt mines, with large, flat-laying acanthites on matrix with calcite. Admittedly crude, but large crystals and overall not so ugly - and very important for the locality! It was found in 1960. From the noted collection of John Durkos, who built the best-documented and most extensive collection of silvers and silver species from the Cobalt area mines during their times of operation. His collection was particularly noted for detail such as when the specimens were collected, which he tracked down with care in buying directly from the miners. His collection passed on to Richard Hauck in the 1990s, who sold this to a silver collector at that time. It has not before been offered for public sale and is, in my opinion, an important and historic Canadian specimen.
