Silver (rich specimen)

Item Description

An impressively rarely seen and notably RICH specimen featuring beautiful crystallized groups of arborescent/dendritic Silver sitting on white massive Calcite matrix with minor associated Dyscrasite and Allargentum(?) according to the label. The Calcite has been partially etched away to expose the intricate and beautifully detailed Silver crystals, which look spectacular under magnification. I can't recall having a piece from this locality with SO MUCH Silver on it, and we've photographed the little crystals with a macro lens to better illustrate the quality. A great piece for any fan of worldwide Silvers or minerals from Morocco. Specimen weight is 247.2 grams. Valued at $2,000.
From the collection of Armon McPherson, a retired physicist, now living in New Mexico. Armon received his PhD from North Carolina State University in 1985, and worked at the laser laboratory at the University of Illinois at Circle Center. In the summer of 1997, Armon moved to the Argonne National Laboratory where he worked at the Advanced Photon Source, then the world’s largest synchrotron facility dedicated as an x-ray source. In 2001, he was asked to join a team at Sandia National Laboratories in Albuquerque to conduct laser research for DARPA. Finally, staying within Sandia, he transferred to the Z Facility, the world’s most powerful x-ray facility. He retired in the spring of 2017. Armon's introduction to mineral collecting came in the 1980s during graduate school when he attended his first mineral show. He took up the hobby of faceting gems, and focused his early collection on gem crystals, and later transitioned into collecting non-gem species. We are proud to offer specimens from his worldwide mineral collection here for you.
