Jordanite, Sphalerite - Lengenbach Mine, Binntal, Valais, Switzerland (found before 1899)

 Magnificent specimen from the Lengenbach mine in the Binn Valley with attached collection label by A. Janson 1899 #136

 Two Jordanite crystals, approximately 8 mm in size, combined with blood-red sphalerite crystals, sit on the known pyrite-ridden matrix.

 Spectacular, historic stage!
