1.9 x 1.5 x 1.0 cm. A superb silver wire thumbnail from Creede, Colorado. Two silver wires curl upward from the dense silver wire nest, into what looks like a natural arch, but in fact, are two separate wires. Ex. Irv Brown Collection.
2.5 x 1.7 x 0.3 cm. A highly aesthetic, curved and twisted, snake-like, silver wire beautifully accented by a flattened calcite rhomb from a mine in Zacatecas, Mexico. The wire is nicely burnished. Classic, older material from the Irv Brown Collection.
1.2 x 0.8 x 0.6 cm. A really fine thumbnail cluster of brightly burnished, spinel-twinned silver crystals in a fan-like pattern. Some of the crystals are flattened and have chisel-like terminations. This showy piece is from an uncommon Mexican locality for silver - the La Encantada Mine in Coahuila.
For native elements, Tsumeb has always been a bit disappointing in terms of specimen recovery: especially for silver, of which so few fine specimens are known and of those, most are simply not display-worthy. This brilliant piece, however, is quite an exception! It features exquisite OCTAHEDRAL silver crystals to 3 mm set in massive silver, with spots of cuprian adamite to prove the locality is legit! In person, it is a much richer, silvery tone than it appears. Specimens of this richness are EXTREMELY RARE and hard to come by. The famous Barlow collection Tsumeb silver illustrated in his book, which I handled at one time, had perhaps 1/10th the silver as does this specimen though of course much more size and heft in the rocky matrix. I would choose this one every time, for its attractive, brilliant display qualities. From the Nauke Oechslin Collection, purchased in Africa in the early 2000: a noted collection mentioned in Gebhard’s Tsumeb books. 4 x 3.5 x 1.25 cm
6.2 x 4.3 x 3.5 cm. A very sculptural, wing-like, solid silver specimen from the historic mines at Kongsberg, Norway. This beautifully burnished piece presents an entirely different view with every rotation. Uniquely, this classic, old-time specimen has areas of rainbow iridescence. Weighs 152 grams or 5.3 ounces.
2.2 x 0.9 x 0.2 cm. A superb silver "feather" from the famous Copper County of Michigan. This classic, old-timer has high lustre and a beautiful patina. Ex. Clarence Bement, American Museum, Bill Severance and Irv Brown Collections.
16.1 x 11.0 x 6.8 cm. The Pohla silvers are known for their extremely photogenic herringbone-like crystallization (dendritic growth), which you see here in all its intricate beauty. The silver is embedded in and flowering out from massive matrix of silver and arsenic ore. To emphasize the size of this 6-inch-tall specimen, it weighs in at 4 pounds of solid silver and arsenic ore. Ex. Victor Yount dealer stock.
A dramatic, arborescent silver specimen from the classic finds of the 1960s and 1970s with tall, stout, thick crystals to 3.5 cm that stand straight up! THESE ARE NOT the typical thin, fragile wires…but rather they are sturdy, thick spinel-twinned crystals. THis is one of the better specimens in a lot I have slowly been liquidating which comes from the estate of well-known collector Al Buranek, and it is the best I have put in auction to date. Valued at $600-750. Even when they were common, dramatic pieces such as this were not common at all. 6.3 x 4 x 2 cm
A small but EXTREMELY fine silver mineral thumbnail specimen with a fine curled silver wire right next to a perfectly formed crystal of acanthite, all perched on a bed of massive acanthite and smaller wires. The aesthetic balance and symmetry of the piece is just amazing, and I have never seen a Peruvian silver thumb I liked better. 2.3 x 1.8 x 1.1 cm
An excellent 2-piece deal (thumbnail, and miniature ) of arborescent herringbone silver wire crystals etched from enclosing calcite from the famous New Nevada Mine at Batopilas, Mexico. These cute silver specimens are from the 1970s and come from the noted collection of Al Buranek (Thumbnail & a Miniature)
5.1 x 0.9 x 0.5 cm. A very aesthetic, barbed silver "spear-point" from the famous silver mines at Pribram, Czech Republic. This old-time, classic is, in fact, a very elongated spinel-twinned silver crystal. The "barbs" are tiny, flattened, secondary spinel-twinned silver crystals. Excellent patina on this fine old-timer and the interior of the long twin has a nifty herringbone pattern.
A TRULY EXQUISITE specimen of arborescent herringbone silver wire crystals etched from enclosing calcite from the famous New Nevada Mine at Batopilas, Mexico. The piece consists of a gorgeous herringbone silver flag with a 3.5 long single silver wire crystal extending from the flag, protruding through calcite and having two silver crystals attached near the tip of the long wire. Silver crystals of this length are very uncommon from Batopilas. ex. noted collection of Al Buranek. 5.5 x 1.4 x 1.3 cm
4.6 x 2.5 x 0.6 cm. A fine silver "feather" of isolated, very elongated, spinel-twinned silver crystals accented by calcite and a bit of matrix from the famous finds at the New Nevada Mine at Batopilas, Mexico in the early 1980s. The silver crystals have a very nice, iridescent patina.
2.4 x 0.8 x 0.3 cm. An elegant, finely-crystallized silver specimen from Michigan. Ex. Seaman Museum Collection.
12.2 x 9.3 x 2.3 cm. This solid mass of vein silver is dotted by unusual spherules of lustrous, cranberry red erythrite to 2mm across. There are enough erythrite crystals to form a distinct red swath on the silver. Weighs 873 grams. Ex. Richard Hauck Collection.
