This is almost a wonderful specimen of pyrargyrite. It shows nice crystalization, with a variety of shapes including parallel prismatic crystals, although there are a few similar appearing hexagonal polybasite crystals also present. The pyrargyrite is distinctive in that it is ever-so-slightly translucent and appears dimly red when viewed carefully. If the pyrargyrite had not darkened to nearly black, this would be a nice specimen, indeed.
