A superb association specimen from the San Jose mine. These specimens came out in 2006, and are among some of my favorite "new finds" from Bolivia. This piece is one of the very finest miniatures of this hard to find association to come out. It features hundreds of excellent, rare, prismatic, silvery-grey "needles" of Zinkenite which are associated with good sized, sharp, very dark silvery "brass" colored, twinned crystals of the rare copper iron tin sulfide Stannite. The final touch to this specimen is an associated silvery color tabular crystal of Andorite. There were only a handful of these specimens found. Ex. Brian Kosnar Collection.
