Plattnerite (ex Kay Robertson Collection)

Item Description

Please Note: This specimen is simply labeled as coming from "Val di Parma", which is not a reported locality for Plattnerite in Italy, so we don't have an exact locality for it. If anybody out there was information as to where the piece is from, please let us know. With that said, this small cabinet / large miniature features small, sparkling, semi-metallic, radiating "sprays" or clusters of black Plattnerite on matrix. The Plattnerites are best seen under magnification, like most specimens of this rare lead oxide. Ex Kay Robertson Collection (#7364). Kay was a prominent California collector, who specialized in European classics. She nearly lived 100 years from April 1920 - March 2020.
