Orthoclase Var. Adularia
Cabinet, 10.1 x 9.5 x 6.0 cm
Vizze Valley (Pfitsch Valley), Bolzano Province (South Tyrol), Trentino-Alto Adige, Italy
Ex. University of Arizona
This is a classic alpine style specimen: a large, fist-sized cluster of gemmy, translucent orthoclase feldspar crystals. The cluster is a floater, complete all around. It is unusually pristine and sharp, and very 3-dimensional in person. The photos show it in normal frontal lighting, though it has a better "glow" to it when backlit. Impressive, in person! From the collection of Hubert De Monmonier (1919-2007), donated by bequest to the University of Arizona Museum to add to their displays and to provide specimens for sale to establish an endowment fund for museum operations, in perpetuity.
