Bournonite with Tetrahedrite (Subgroup) and Siderite
 

SV3220EFA: A classic among the classics, these bournonites associated with 'Tetrahedrite' have good quality and above all, very good state of conservation, which is not very common in specimens from this locality.
The contrast with the brown Siderite helps to visualize the definition of the crystals even better, both for the Bournonite as well as the 'Tetrahedrite'.
