A large specimen with etched out branching, or arborescent and herringbone habit Acanthite crystals which were formerly Silver crystals. Very rich and fascinating piece. Heavy too, so maybe extra for shipping.

Large specimen of probably 75% Acanthite. The Acanthite is massive at the core but along much of the outer edges is free-standing melted-looking blobs so typical of Acanthite. There is also, although minor, plates of Polybasite and Pyrargyrite.

Rich specimen with a great amount of Acanthite as oddly shaped crystals, mostly modified cubic forms. It is also rich in yellowish Fluorite. Some of the cubes you can see in the photos are actually the Fluorite coated with Acanthite.
