Rosasite on Quartz (ex Kay Robertson Collection)

Item Description

A lovely specimen of Rosasite from Mexico which according to the label is from a placed called Astillero in Durango, Mexicao but I can't find a listing for this locality. It features gorgeous, rich greenish-blue colored radial aggregates of Rosasite with individual "balls" measuring up to a few mm on sparkling / drusy silvery colored Quartz on matrix. No real damage that I can see with the naked eye, and a great piece to add to a secondary ore collection or a suite of Mexican minerals. Ex Kay Robertson Collection (#1128). 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).
