Cronstedtite mindat

It was recognized as a species since about 1890. By far the best locality for specimens appears to be the Herja mine in Romania. 3.5 x 2.3 x 1.8 cm. Cronstedtite is a rare iron silicate of the serpentine group. This very rich and showy little specimen is festooned with lustrous, black, trigonal crystals to 3 mm on a 3-dimensional crust of matrix.

Chlorite is commonly found in igneous rocks as an alteration product of mafic minerals such as pyroxene, amphibole, and biotite.In this environment chlorite may be a retrograde metamorphic alteration mineral of existing ferromagnesian minerals, or it may be present as a metasomatism product via addition of Fe, Mg, or other compounds into the rock mass.
