Here's a sharp group of stacked, doubly terminated, lightly SMOKY QUARTZ crystals that form a large and spectacular “GWINDELS” (twisted quartz crystals which can occur when unusually flattened crystals are stacked one atop another and twisted in corkscrew fashion). This crystal comes from Mont Blanc, Chamonix, Haute Savoie, Rhone-Alpes, France. The standard growth direction for quartz is along the axis which is horizontal in this specimen. Gwindles grow perpendicular to those regular old hexagonal prisms. To boot, this crystal has a 25Ḟ twist along the vertical axis! The bizarre name comes from the German word for twisted. I acquired this fabulous specimen from a French dealer at the Tucson Gem, Rock & Mineral Show.
