Rich group of complex and brilliant chalcopyrite crystals contrasting on a matrix of barite crystals. They are accompanied by interpenetred rhombohedral dolomite crystals. The specimen belongs from the Dreislar mine, a mine that was operated from 1970 to 2007, with the usual interruptions, for lead, zinc and copper, and more modernly for baryte. The specimens are classics in German collections.

Size: 8.8 x 5.5 x 3.4 cm.
Main crystal: 7 mm.

Classic locality

The galena specimens from this classic German mine are known for the size of the crystals and twins. In this sample both characteristics are fulfilled. We can observe interpenetrated crystals according to the spinel twin law and other crystals shoewing the cube and octahedron faces. On matrix with tetrahedrite crystals partially covered by brilliant chalcopyrite and some siderite. They stand out for their size and quality. On a matrix with pyrite and siderite crystals.
This piece is from the collection of Renaud Vochten (1933-2012), a well-known Belgian collector of mineralogical rarities and it was in the collection of the University of Gent. An unusual opportunity to get an excellent sample of this classic European mine.

Size: 9.0 x 6.8 x 4.0 cm.
