1.9 x 1.2 x 0.7 cm. This piece really catches one’s attention. Typically the Silver specimens from Bolivia are somewhat "flat" and boring, but this piece is amazingly aesthetic for a Bolivian Silver. It is a fine, decent-sized (for this mine) group of wires forming a very attractive specimen. This is a great thumbnail specimen from a classic Bolivian locality. The mine at Porco is THE oldest and most significant Silver mine in Bolivia, and obtaining specimens is next to impossible because miners rarely bring out anything for sale, as the mine is a large commercial production, and virtually everything goes into the crusher. Most everything that evades the crusher is usually taken out of Bolivia by a geologist who has an "in" at the mine. This is why it is so difficult to obtain any good Silvers from Porco. Ex. Brian Kosnar Collection.
2.4 x 1.8 x 1.1 cm. From one of the two most "classic" European silver localities - a tight mass of well-defined wires of silver, with an "antique" patina. Not a world-class Kongsberg silver, but a good representative specimen of a valued and hard-to-find locality piece for a thumbnail collector.
9.3 x 5.1 x 4.2 cm. A GORGEOUS and thick nest of brightly burnished silver wires to 2.7 cm very aesthetically set in a 3-dimensional vuggy matrix of solid acanthite from a recent find at the Imiter Mine of Morocco. The silver wires are a marvel to behold and this super piece definitely has two displayable views.
5.4 x 3.2 x 2.9 cm. You cannot get much more of an American classic than an old nugget of silver from Creede, Colorado! This specimen is heavy and rich with silver, I would say about half-and-half silver/quartz. A chunk of history! Weighs a hefty 103 grams . Ex. John Ydren Collection.
3.7 x 2.2 x .8 cm (largest). Some of the world’s loveliest, most delicate Silver specimens have come from Batolpilas, Mexico. Not only do these both have the delicate beauty one looks for in terms of fine luster and good crystal habit, but both are blessed with attractive Calcite rhombs attached to, and accenting, the Silver crystals. Very good representative pieces for the locality.
1.3 x 1.0 x 0.3 cm. An aesthetic, arborescent native silver thumbnail from the famous Elkhorn Mine of Montana. The flattened crystals have a very nice patina. This is excellent, old-time material from this historic mine and seldom available. The Elkhorn Mine is the subject of an extensive article in the current issue of Rocks and Minerals.
2.7 x 1.4 x 1.1 cm. Typically the Silver specimens from Bolivia are somewhat "flat" and boring, but this piece is amazingly aesthetic for a Bolivian Silver. It is a fine, decent-sized (for this mine) group of wires forming a very attractive specimen. This is a great thumbnail specimen from a classic Bolivian locality. The mine at Porco is THE oldest and most significant Silver mine in Bolivia, and obtaining specimens is next to impossible because miners rarely bring out anything for sale, as the mine is a large commercial production, and virtually everything goes into the crusher. Most everything that evades the crusher is usually taken out of Bolivia by a geologist who has an "in" at the mine. Ex. Brian Kosnar.
5.2 x 4.2 x 1.8 cm. An unusual copper country specimen featuring 2 isolated, sharp, distinct silver crystals perched upon a large and hefty "mass" of copper that appears crystalline on the surface but in an odd flattened manner. Such a separation, with such stark contrast, of the two elements is uncommon.
5.3 x 2.7 x 0.4 cm. A sheet of natural silver, from a thin seam the in host rock, with a coating of slightly iridescent bornite (the darker, blue-to-gray areas) - from the rich Zacatecas Silver District of Mexico.
3.4 x 2.3 x 1.2 cm. These are little patches of spinel-twinned crystals, actually very sharp and finely articulated even if small, on matrix -- from Chihuahua. Classic from the 1960s and 1970s.
2.2 x 0.7 x 0.7 cm. An aesthetic, arborescent native silver thumbnail from the famous Elkhorn Mine of Montana. The flattened crystals have a very nice patina. This is excellent, old-time material from this historic mine and seldom available. The Elkhorn Mine is the subject of an extensive article in a recent issue of Rocks and Minerals. Ex. JohnYdren Collection.
1.9 x 1.8 x 0.4 cm. A fine crystallized silver from the rich silver and uranium Bonanza Mine in Canada. The specimen shows intricate herringbone crystallization - in fact, it is completely crystallized. Ex. Noted thumbnail collection of Allan Young.
2.9 x 2.3 x 1.1 cm. A CLASSIC, OLD-TIME and rich Arizona specimen of thick curled silver wires on a matrix of solid silver from the famous Silver King Mine, near Superior. The piece is nicely burnished with acanthite. The Silver King Mine was discovered in 1873 and was depleted by 1888! A fine piece for the Arizona, locality or elements collector. Ex. George Elling Collection.
4.3 x 4.3 x 2.7 cm. An old-time, very rich silver ore specimen UNUSUAL and UNCOMMON associations from the very famous Chanarcillo mines of Chile. The 3-dimensional specimen is nearly solid silver with a scattering of black acanthite. One end is RICHLY covered by white tufts of pharmacolite, an UNCOMMON hydrated arsenate. Ex. Carl Davis Collection.
6.1 x 3.9 x 3.2 cm. An OLD-TIME, showy and extremely rich silver ore combination specimen from the famous Eagle Mine of Colorado. Barbed, spinel-twinned silver crystals to 4.8 cm! saturate the matrix, which is solid pastel-pink rhodochrosite! The silvers have a variable patina, which adds to the attractiveness. Hefty for its size at 110 grams. A CLASSIC Colorado silver. Ex. John Ydren Collection.
