In this floater specimen we can observe a rich group of quartz crystals, one of them dominant, with well defined faces and edges. We see a well-developed prism with rhombohedral terminal and trapezohedron faces. Transparence and brilliance are both excellent and with a very uniform smoky tone. It is not easy to find specimens from this Alpine quartz locality.Note:  Le Règne Minèral. Minèralogie du Massif du Mont-Blanc. Hors Sèrìe V, 1999. 1p6j68
