A beautiful near "floater" specimen of the so-called "Fensterquartz" from an old find at the famous Alpine locality of Val d´Illiez of Monthey in Switzerland. Here in Europe, these skeletal Quartz specimens are mostly called "Fenster" (German word for window), due to the fact that the pyramidal and prism faces have a skeletal form that gives them the appearance of a window. The creamy to beige coloured "mud" inclusions are some kind of pocket clay that was frozen inside of the Quartz as it was crystallizing. Where there are no inclusions, the Quartz crystals are water-clear, and have sharp, glassy surfaces all the way around. A very interesting doubly-terminated, multi-crystal specimen of this unusual material. This great and highly aesthetic specimen comes with a high quality custom base.
