Acanthite Ps. After Argentite
T
The ArkenstoneFeatured
This piece, surely very old, is a major classic European silver specimen. Hefty at 283 grams, it hosts a massive cubic crystal of acanthite that is 4 cm on longest edge and in a cluster with other sharp cubes. Technically, this is acanthite ps. argentite according to some people (based on crystal shape), though often they are just labeled as acanthite. From the Eric Asselborn collection. Complete all around, 360 degrees. Joe Budd photos.
