Item Description

A classic old time specimen of the famous Huaron Chalcopyrites featuring sharp, well-formed, robust, metallic, brassy colored crystals measuring up to 1.8 cm associated with thin prismatic colorless Quartz "needles". I can only see tiny imperfections, but the piece is in excellent condition. A wonderful attractive miniature of this classic material. Mined circa 1970s - 1980s. Ex Kay Robertson Collection (#12001) with an old label from van Sciver's Minerals. 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).
