Native Silver ps. after Dyscrasite

A superb miniature of Native Silver pseudomorphing after Dyscrasite from the Příbram mining district in the Czech Republic.  On the whole, the Native Silver retains its natural greyish-silver colour and forms a spongy replacement structure pervaded with tiny voids.  The shape of former Dyscrasite crystals richly populate the specimen, the most prominent pseudomorph measuring almost 3 cm tall by 0.5 x 0.5 cm in cross-section.  Some of the outside edges of the pseudomorph replacements have a solid sooty-black coating of probable Acanthite.   A terrific specimen of both Native Silver and very good pseudomorphed Dyscrasite crystals.
