Item Description
Tiny bright orange-red cuprite variety chalcotrichite hairs and wine-red cuprite richly covers both sides of this sculptural flattened crystallized copper specimen from one of the mines at renowned Bisbee. A significant and rich old-time copper combination, probably dating to prior to World War I. Ex Kay Robertson Collection # 109 and acquired from Rocky Crowther in the early 1950s or earlier, with the very low specimen number. 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). Classic and rich old-time crystallized Bisbee copper with chalcotrichite and cuprite.
