Argyrodite from Gallofa mine, Colquechaca, Chayanta, Potosí, Bolivia
All of the arrows point to clusters of Argyrodite crystals. The crystals are multiple penetaration twins not easily seen. Recognizable faces of these twins are six edges enclosing an "indentation" at the center. A good diagram can be seen on Mindat. This is a real good identification key for Argyrodite. The specimen is indeed rich with Argyrodite. There are also numerous cherry red Pyrargyrite crystals not more than 1mm.
