Pyromorphite (important old locality specimen) (ex Kay Robertson Collection)

Item Description

Of the many hundreds if not thousands of localities for Pyromorphite in the world, the type locality is Zschopau in Saxony, Germany. Most people have never seen a Zschopau Pyromorphite in person. This piece features fairly sharp, prismatic, thick, hexagonal yellow-green colored crystals of Pyromorphite on matrix. The largest Pyromorphite measures 5 mm long. Some of the crystals are slightly bruised in areas, so the piece is not completely pristine, but this is still an important specimen dating back possibly a couple hundred years (the species has been known since in the 1700s). Ex Kay Robertson Collection (#5940). 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).
