This specimen features a thick nest of silver wires shooting up from the acanthite matrix, with small curlicues at the base of the silver. Extremely rich, this is a dramatic piece thick with the silver all over its display face atop. It is very impressive in person and the contrast of extremely bright silver vs the black matrix is striking. In fact, this is one of the largest silver specimens we have yet seen from the Imiter finds, which came out a few years ago. It was priced when I saw it at over 20,000 euros, but I obtained it in exchange and amortised down to make it affordable. For a Kongsberg, Peruvian, or now even Chinese silver, you would pay a lot more for a piece that has a lot less significance for the finds.

Seldom do you see old acanthites from this ancient district, isolated and on matrix. These relatively sharp crystals, to 1.2 cm in size, are really aesthetic, compared to most of the old acanthites we see from here. The matrix is 3-dimensional, and the piece is complete all around. It was in the noted collection of Arthur Montgomery, in the early 1900s. Recently, it was also in the noted classics collection of dealer/collector Larry Conklin. The crystals have a bright and natural patina and luster that is not the result of fancy chemistry to clean the piece, or whiten the siderite.Joe Budd Photos
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.
The photos say it all - this is a MAJOR acanthite for any Canadian locality, let alone from the cobalt mines where few large specimens were ever found and saved. It is dramatic and well crystallized, with several habits present on the specimen. It was found in 1963 and sold by the miner to John Durkos: 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.

From the collections of William S. Vaux (1811-1882), a true classic from South America's most important ancient economic silver mine. The matrix of this rather hefty specimen is heavily included by patches of very visible, silver wires that exhibit a wonderful, metallic-iridescent, patina. Sharp cubic crystals of acanthite to 1 cm on top are present, on massive acanthite ore. The mines at Colquechaca have been in operation for hundreds of years. This specimen was from the Philadelphia Academy of Natural Science collection and was contributed by one of its founding families.

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 minaiture. In person it has a bright and shiny lustre , and is not "black." Ex University of Arizona collection, by donation in the past.
