Twinned Bournonite crystal, isolated, very aerial and large, shiny and on matrix, with complex Pyrite crystals, twinned Sphalerite crystals and small white Calcite crystals.

Bournonite with Tetrahedrite (Subgroup) and Siderite.
SV3220EFA: Bournonite with Tetrahedrite (Subgroup) and Siderite
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'.
