RM1531   Galena with tetrahedrite, chalcopyrite and siderite

Pfannenberger Einigkeit Mine, Salchendorf, Neunkirchen, Siegerland, North Rhine-Westphalia, Germany

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.

RM1626   Pyromorphite on quartz and chalcopyrite

Rosenberg Mine, Braubach, Bad Ems, Rhineland-Palatinate, Germany

A classic pyromorphite specimen of excellent quality, rich in hexagonal prisms, very well defined, with the typical beige-brown color of the specimens of this German locality. Translucent to transparent. Matrix is formed by quartz crystals which makes the phosphate stand out in a very aesthetic way. It is accompanied by chalcopyrite. One reason to select this specimen from the Daunis collection is the old label of Juan Montal, a well-known Catalan mineral dealer from Vilafranca del Penedés (Barcelona), who was active in the middle of the s.

Solid cluster of intergrown nickelskutterudite (formerly called chloanthite) from the historic Schlema-Hartenstein District. Chloanthite is now regarded as an arsenic-deficient variety of nickelskutterudite or simply as a synonym for nickelskutterudite. Nowadays is very complicate find specimens of this size and quality. Complex crystals, bright, with faces... A piece highly valued by mineralogists. From the Type Locality. Formerly in the collection of Gerd Resag. Only for "deep & dark collectors".
