Kämmererite, or Chromian Clinochlore, is the rare chromium (Cr) rich variety of Clinochlore. It is a very beautiful mineral with intense colors of pink, bright purple and rose to deep crimson red. Kämmererite is micaceous so it is extraordinarily difficult to facet because of its perfect basal cleavage. Faceted gems are extremely rare and those that exist are usually very small.

Kämmererite was named in 1841 by Gustaf Nordenskiöld in honor of August Alexander Kämmerer (1789 - 1858), the Ober-Bergmeister, chemist in the Mining Department of Russia. He was the author of several geological and pharmaceutical works. The name Clinochlore is from the Greek words klino meaning oblique and chloros meaning green.

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