Embedded feldspars and muscovite plates on the smokies are a nice accent. Ex Kay Robertson Collection # 10847 and acquired at the Munich Show in October, 1985. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).

Trespassing in the mining area is prohibited, however, the place is not guarded (MINDAT).
