Gemstone of the Week: Kämmererite

(Kämmererite image found on

 Kämmererite is the red to purple variety of Clinochore (an ordinarily green gemstone). This beautiful gemstone was discovered in 1851 and is named after the A. Kämmer (the mining direct at St. Petersburg).  It has a hardness of 2-2.5 so it's use is somewhat limited and great care must be taken with it. Its colour may be bright purple to a deep crimson red.  Often, it will be found in chromite deposits along with Clinochlore and Uvarovite (a type of green Garnet).   Kämmererite is a very rare gemstone and may be found in Turkey.
