Pyromorphite (rare material) (ex Kay Robertson Collection)

Item Description

From an obscure locality in Wales, this Pyromorphite specimen features thin, prismatic, hexagonal fine green color crystals covering the Quartz matrix. This is a hard to find, pretty, interesting locality piece! Dealers in the late 1970's to early 80's deliberately labelled them obscurely to prevent collectors from finding the site. Unfortunately it didn't really work and as a consequence many are labelled as Plynlimon or even corrupted to Plynlimon Mine, which has no real minerals of interest. Valued at $500. Ex Kay Robertson Collection (#8721) with a label from Lindsay and Patricia Greenbank. 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).
