Binnite crystals from the Lengenbach Mine, Binntal, Switzerland – miniature specimen as unique piece
This miniature specimen features Binnite in its characteristic habit on light-colored dolomite matrix from the famous Lengenbach Mine in the Binn Valley. The clearly visible dark gray to black lustrous crystals stand out beautifully against the white matrix and display the typical prismatic to elongated crystal form of the species. The crystals are well developed and remarkably prominent for a specimen of this size. The combination of strong visual contrast and a classic Alpine locality makes this piece especially attractive for collectors of rare sulfosalts.
Geology & Origin
The Lengenbach Mine in Switzerland's Binn Valley is one of the world's most important localities for rare sulfosalt minerals and has produced numerous scientifically significant mineral species. Binnite is a complex lead, copper and arsenic sulfosalt that formed within the dolomitic rocks of the deposit under specialized hydrothermal conditions. The locality enjoys an international reputation among mineral collectors because many of its minerals are known from only a few places worldwide. Well-defined Binnite crystals from Lengenbach are therefore highly desirable collector specimens.
