Chrysotile (Metaxite) (rare locality specimen) (ex Kay Robertson Collection)

Item Description

An incredibly hard to find specimen of Chrysotile (Metaxite) from Zloty Stok (Reichenstein) in Poland. The piece was oringally labeled as Serpentine (var: Metaxite), but Metaxite is actually a synonym for Chrysotile. I've never seen a piece of this material before. This piece consists of a compacted mass of silvery-grey colored Chrysotile with no actual crystal form that I can see. VERY rare, and certainly worth adding to any suite of European minerals or a collection of Serpentine group minerals. Ex Kay Robertson Collection (#6526). 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).
