This unusually sculptural and very well-crystallized acanthite was once part of the world famous silver mineral collection of Terry Wallace, who up to recent years was a professor of geology at the University of Arizona and curator of the incredible Romero collection there. Later from Evan Jones personal collection. As far as I can tell, this specimen is pristine. The dark, battleship gray, color and good luster are highlighted by raised crystal edges, giving this extremely modified piece, an almost hopper-like appearance. Front and back are shown, as well as a side view. Rare and superb.
