Acanthite Pseuomorph After Pyrargyrite
This is a rare specimen not of Acanthite after Argentite, but of Acanthite pseudomorph after Pyrargyrite.This is not often seen! It was a very old piece that was in the famous pseudomorph collection of Ed Swoboda by the 1970s. It is complete all around, and very 3-dimensional. It is good all around, 360 degrees. It has robust structure and interesting form. When Ed Swoboda sold his pseudomorph collection in the late 1990s, this went to Jim Minette and Carter Rich. They in turn sold it to Dr. Ed David. I obtained it from Ed in a deal in December of 2001, and sold it to Dave Stoudt within days - where it has remained since. Joe Budd photos.
