This old-time specimen is labelled Argentite, but as so eloquently explained by mindat, Argentite is only stable above 177 degrees Celsius. Hence, it is the low temperature silver sulphide species Acanthite, but crystalised in the habit of Argentite. With this now explained, it is a sublime specimen and a magnificent example of this silver species from 366 Mine at Alberoda in Saxony, Germany. Mounted on a bevelled clear acrylic base, the Acanthite forms a vertically backwards-curved rib of horizontally stratified pseudo-cubic crystals, measuring 6.1 cm tall. Of metallic silver-grey, crudely crystallised Acanthite ribs project out either side of a central 'backbone', giving the entire specimen a sharp, hackly texture and appearance. Pinkish-grey Quartz grains are sparsely strewn amongst the Acanthite which more defines the central vein-like centre. Another interesting feature towards the base of the concave side, the Acanthite spreads either side of the centreline in a semi-herringbone structure. This is a magnificent example of Acanthite pseudomorphing after its high-temperature polymorph Argentite, and from Saxony to add even greater appeal!
