An elegant, curvaceous silver from finds of about 2 years ago that are only now trickling out of China. VERY fine for the size and reminiscent of old German and Norse material! 4.5 x 3.5 x 1 cm
This is a damned near unique specimen, the likes of which I personally have never seen. Logically, the alteration makes sense of course. But in practice, it almost never occurs. The silver is a coating of 1-3 mm, over remnant pyrargyrite....so one could say it is a partial or surface alteration, but a pseudomorph nonetheless. I was able to track down a report of a similar specimen , via a reliable source. But i have NEVER seen one for sale or even in a museum record. And, moreover, this is aesthetic and highly displayable! The old label from Mitch Gunell's Collection notes that he purchased it from the late, great Martin Ehrmann in 1940. Gunnell assembled what is widely considered to have been the most comprehensive pseudomorph collection ever, and this pedigree carries value. But, I feel the mineral is priced on its own merits in this case, with the pedigree as a bonus. 4.1 x 2.4 x 2.4 cm
Finely-crystallized silver wires wrapped around calcite matrix, from the Hauck Collection. 3.9 x 1.7 x 1.2cm
An old-time, classic, nearly pure specimen of fine silver wires from an uncommon Canadian locality in the Yukon, the Lucky Queen Mine. Ex Richard Hauck Collection. 5.1 x 4.2 x 3.8 cm
A CLASSIC, aesthetic, old-time specimen from the Sorbonne Museum collection of elongated, spinel-twinned silver wire crystals to 2.7 cm on massive silver matrix from the most classic locale of Kongsberg, Norway. Ex Gilbert Gauthier (with label) and Richard Hauck Collections . Sorbonne label! 69 grams. THis is a hefty, solid, important crystallized silver specimen for a mine known for its wire silver, mainly. 5.2 x 3.8 x 2.1 cm
A sheet of native silver, coated with blue-gray bornite, from Zacatecas. Not flimsy, but actually quite substantial. 6.4 x 3.5 x 0.8cm
A SHOWY and excellent combination piece from Michigans famous Copper Country of antler-like, spinel-twinned, silver crystals with a flat plate of copper with a very nice patina. Interspersed milky quartz nicely sets off the native metals. This fine piece was recovered from Lake Superior and hails from the Richard Hauck Collection. 6.7 x 4.2 x 3.0 cm
A SUPERB and AESTHETIC iridescent cluster of herringbone-patterned, elongated spinel-twinned silver crystals with nicely attached calcite matrix from the famous Batopilas District of Mexico. Ex Richard Hauck Collection. 3.0 x 2.7 x 2.4 cm
A RICH old Cobalt wire specimen, with a thick, aesthetic, twisting arrangement of ropes and wires on a sparing matrix. Superb, dramatic aesthetics comparable to what you expect from European silvers, but seldom seen in Candian pieces! This is thus not only an old classic, but of unusually high display quality for the material. 2.5 x 2.5 x 1.8 cm
A completely crystallized mini of native silver from the classic Cobalt locality! The crystals have a delicate, branch-like structure. 3.6 x 2.1 x 1.8cm
An AESTHETIC silver specimen from the Imiter Mine of a tower of lustrous, banded, parallel-growth silver wires perched on similar silver wires. Rare! 3.8 x 3.5 x 2.7 cm
SUPERB, VERY RARE and lustrous cubic silver crystals to 3 mm nearly cover the matrix of this Batopilas, Mexico silver specimen. Cubic silver crystals are rare from any mine and are nearly unheard of from Batopilas. This is festooned with them. This is thus a UNIQUE specimen from the Al Buranek Collection. with label. You can see form the label that it was originally described AS a Michigan silver BECAUSE of the cubes, which you wouldnt associated with Batopilas normally. Well, it got corrected, and i have confirmed the correction as well, and its worth a lot more now than if it were just from Michigan. Silvers of cubic form are the rarest sort, and this is so rich, and so pretty, and its so rare in cubes for the locality, that the piece has significance beyond its beauty. 5.2 x 5.0 x 3.5 cm
An EXCELLENT, VERY RICH, CLASSIC, OLD-TIME wire silver specimen from the upper oxidized zone of the famous Broken Hill Mine of Australia. Fine silver wires to over 1.5 cm abundantly cover the calcite matrix. 5.4 x 3.7 x 3.3 cm
A fine "feather" of silver from the famous Batopilas locality, renowned for elegant naturally crystallized specimens such as this. 3.1 x 0.3 x 0.2cm
Excellent stout, single spire of spinel-twinned silver with a beautiful patina. Sharp and very attractive. Silver is EXTREMELY RARE for the locality in such sturday, well defined crystal form! 2.6 x .8 x .8 cm
