Anatase (classic material) (ex Kay Robertson Collection)

Item Description

This piece came labeled as coming from the "Lukmorierschlucht (sp?)" in Grischun (Grisons), Switzerland. It could be from Selva or Cavradi, which are the two most likely / classic localities for blue Anatase from Grischun, but it's hard to say. The crystal measures 2.5 mm and shows a fantastic, textbook, steep pyramidal tetragonal crystal with a rich royal blue color sitting on bladed Albite matrix. No damage that I can see with the naked eye, and the piece would make a superb addition to a thumbnail suite or a collection of Swiss minerals. Ex Kay Robertson Collection (#9156). 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).
