For sale is a fine arsenic cast after native silver, from Shaft 366, Schelma, Germany. This specimen has superb definition as can be seen in the pics. Arsenic, is sometime not remembered as a native element that crystallizes on it own, I find all crystallized native elements fascinating. This interesting specimen I acquired , labeled as arsenic pseudomorphing silver, but the more I thought about it, the less I could believe one native element pseudomorphing another, its extremely unlikely! After much research I final got the correct identification from the famous Russian mineralogist Pavel Kartashov (thanks Pavel) . What has really happened here is that the two minerals silver and arsenic were in association, then came in injecteion of hot mineral rich fluid into the pocket, this fluid dissolved the silver, leaving a perfect cast on the unaffected arsenic. Please remember our prices are in Australian dollars.
