Excellent specimen formed by numerous sheaf aggregates of stilbite (Desmin in the label) crystals. Colourless to slightly yellowish. They are accompanied by smoky quartz crystals, very visible on the backside of the specimen. This piece belongs from the Freiberg Bergakademie, specifically its label tells us that it was sold in the shop that was created to sell minerals, surely for students. The handwritten label can be related to Wilhelm Maucher (maucherite, 1879-1930), a mineralogist and mineral dealer in Munich and who was a "faktor" with the school between 1904 and 1909.

Really good specimen from the high Swiss mountains of the Galenstock area, 3586 m., known for its smoky quartz. This good sized piece shows several of them, with excellent transparence, very uniform smoky tone, with defined faces and edges and partially covered with 'chlorite'. They are accompanied in the matrix with numerous crystals of adularia (variety of feldspar K), well defined. A piece for the display.
