Descloizite (classic material) (ex Kay Robertson Collection)

Item Description

It goes without saying that the finest pieces of Descloizite in the world were found at Berg Aukus. These pieces go back 50+ years and still remain as the standard of excellence for this zinc analogue of Mottramite. This piece features classic "spear"-shaped, sharp, lustrous, rich silvery brown color, layered crystal groups in a semi-stalactitic / arborescent formation. There is some very slight damage on a few of the crystals, but it is still a notable specimen for its crystal quality and overall aesthetics. Ex Kay Robertson Collection (#4232). 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).
