Kop Krom mine, Kop Daglari, Aşkale District, Erzurum Province, Turkey, private collection from Netherlands.

Kammererite is a rare chromium-rich variety of Clinochlore and member of the Chlorite family. It crystallizes in the form of masses, pyramid-like micropoints, and hexagonal crystals. The color can range from dark red, to purple, and even violet. This depends on the amount of chromium impurities within. It was first discovered in 1841 by Nils Gustaf Nordenskiöld, a Finnish mineralogist who chose to name it after August Alexander Kämmerer. Kämmerer was a famous chemist and at the time, the mining director of St. Petersburg, Russia. Since then, it has been discovered only a handful of times in Russia, Norway, Sweden, Finland, the United States, and recently, Turkey. The condition of the sample is good. Age-related wear, fractures and minor cracks may appear. Dirt and dust may exist. Size approx. 3,8cm x 3,0cm x 2,3cm. Weight c. 41g.
