Kämmererite

Kämmererite, or Chromian Clinochlore, maybe the chromium that is rarely a rich variety of Clinochlore. It is a really beautiful mineral with intense colors of pink, bright purple and rose to the deep red that is crimson. Kämmererite is micaceous it is therefore extraordinarily hard to facet due to its basal that is perfect cleavage. Faceted gems are incredibly those and uncommon that exist are usually tiny.

Kämmererite had been named in 1841 by Gustaf Nordenskiöld in honour of Alexander Kämmerer (1789 – 1858), the Ober-Bergmeister, chemist within the Mining Department of Russia August. He had been the author of a few geological and works which are pharmaceutical. The name Clinochlore is the words that are greek meaning oblique and chloros meaning green.

Kämmererite is found in chromite deposits, associated with Chromite, Clinochlore and Uvarovite. The most supply that is notable of is the Kop Krum Mine, Erzurum District, Eastern Anatolia, Turkey.
