A vuggy mass of intergrown, crude, metallic silvery-black Acanthite crystals on a thin granular matrix of sandy-tan quartz. Acanthite is the low-temperature paramorph of the silver sulphide Argentite; at ambient room temperature, only Acanthite can exist. By convention, the crude crystals resembling Argentite in this specimen may be more properly named 'Acanthite after the octahedral high-temperature phase Argentite', although this may require a longer label! This is a great specimen from Schlema in Erzgebirge, Saxony, Germany.
