Chromian Clinochlore ("Kammererite") (ex Kay Robertson Collection)

Item Description

This material is now called Chromian Clinoclore (var: "Kammererite"). Years ago, it actually was a valid species, but most people still call it Kammererite regardless. This is one of those minerals that has one of the most unique colors in the mineral world. Maybe Roselite and Erythrite have similar color, but this amazing purplish-pink is one the most recognizable colors out there. This piece is a nice overall specimen with dozens of sharp, lustrous, gemmy, rich purplish monoclinic crystals measuring up to 1-2 mm on matrix. One of the few pieces of this material that I've offered from this locality recently. Ex Kay Robertson Collection (#7966). 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).
