Description
Yes I admit,- just a Stilbite thumber,- but from a very rare locale, the "Druckstollen" (waterpipe) of Binn in Valais Canton Switzerland. These snow-white crystals here are well developed and sharp edged with excellent terminations. Due to the fact that the specimen was mined during the construction of the underground waterpipe of Binn, such items became immediate history until ending of the tunnel works,- many decades ago now. VERY RARE MATERIAL! Ex Joachim Hennrich collection.
