Pyromorphite (classic material) (ex Kay Robertson Collection)

Item Description

The Bunker Hill mine is a famous lead-zinc-silver deposit that produced some of the finest Pyromorphite specimens from the Western Hemisphere. The mine operated for a century (closing forever in 1988), and fine quality specimens such as this one are difficult to obtain on the market, especially 30 years after it came out of the ground. This piece is a beautiful group of lustrous, golden-orange colored, hexagonal crystals of Pyromorphite aesthetically sitting on matrix to create this beautiful miniature sized specimen. Great shape all the way around, and the crystals have a lovely "stacked" / layered growth with a semi "hoppered" growth. The largest crystal measures 1.1 cm. Classic material from Idaho, you don't see it around anymore, and the best pieces from Bunker Hill are among the best Pyromorphites in the world. Ex Kay Robertson Collection (#9435). 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).
