Copper on Calcite (ex Kay Robertson Collection)

Item Description

A beautiful thumbnail specimen featuring attractive dendritic Native Copper on white Calcite matrix from Bisbee. The Copper is beautiful to vew up close! We have used a Canon MP-E 65 mm macro lens to better illustrate the quality. Ex Kay Robertson Collection (#1827). Please note, originally Kay had this piece labeled as coming from "Katanga, Africa" (Congo), but scratched it out and changed the locality to Bisbee. 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 Velt" November-December 2017).
