<dd>This specimen of acathite after argentite features a series of stacked, octahedral, splendent, jet-black crystals, to 1.8 cm in length. the crystals literally leap out from a matrix of calcite, silver ore, and massive acanthite (few specimens ahve any matrix, here). This new find has lustre - bright sparkling lustre that is hard to convey in photos and quite another world from the appearance of previous finds here. I particularly like the angled group at the top of the specimen, which features a birdlike crystal cluster of 2.4 cm atop. This is a superb, elegant acanthite by any standard, quite different from Mexican and Chinese and German acanthites we might have seen previously.</dd></dl></dd></dl>
