Pyromorphite (ex Kay Robertson Collection)

Item Description

Beautiful, sharp, lustrous, hexagona, bright yellow green crystals of Pyromorphite measuring up to 3 mm sit on Quartz matrix from the lesser known Hardshell Mine. This material is RARE, and if you collect secondary ore minerals, worldwide Pyromorphites or minerals of Arizona, don't miss out on this one as they are virtually impossible to find on the market. Ex Kay Robertson Collection (#10615). 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).
