English: Microcline (Var.: Amazonite), Quartz (Var.: Smoky Quartz)
Locality: Florissant Area, Teller County, Colorado, USA (Locality at mindat.org)
A cluster of lustrous smoky quartz crystals, to 5.0 cm in length, have emerged from a matrix of microcline var. amazonite crystals. They are of high quality, and translucent to transparent! These highly lustrous amazonite crystals are a pastel, blue-green color, and can measure over 2 cm in length. The color and texture contrast along with the aesthetic quality of large smokys and smaller amazonites all add up to make this a fine Colorado specimen clearly of old vintage and different from what is found today. It is possible that one or more amazonite crystals may even be twinned, though I am not quite sure here. There is an insignificant wilber at the termination on the back side of the largest smoky, but otherwise they are complete all around, a miracle for such a large amazonite plate - they are often loaded with repairs, at least from the modern finds. 7.8 x 7.4 x 5.3 cm
