Chromium-bearing Clinochlore (''Kammererite'')

Item Description

For years, this material was considered to be its own species, but now Kammererite is defined as Chromium-bearing Clinochlore. With that said, most people still refer to it as Kammererite. 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 featuring dozens of tiny (drusy) sharp, lustrous, gemmy, rich purplish monoclinic crystals measuring on matrix. One of the few pieces of this material that I've offered from this locality recently. From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974.
