Description
It is difficult to say whether this is an Arsenic or Proustite specimen. Probably more of a combination of both worth seeing. Typically warty dark gray and dull Arsenic aggregates abundantly associated with small, blood-red, sometimes even blackish, highly glossy Proustite crystals. In some places the Arsenic is even covered by a thin reddish film of Proustite microcrystals. Classic material from the 1960s - simply very good
