Kämmererite Crystals aka Chromian Clinochlore
Kämmererite is a rare chromium-rich variety of clinochlore
Another well-known variety of clinochlore is seraphinite, prized for its green colour and feathery-silver markings.
First described in 1841 by Finnish mineralogist Nils Gustaf Nordenskiöld, kämmererite was officially named ten years later in honour of August Alexander Kämmerer, a chemist and senior official in the Russian Mining Department.
Kämmererite is quite soft, so must be handled carefully. On the Mohs scale of mineral hardness, it ranks 2 to 2.5. It's also known as chromian clinochlore due to its high chromium content, which gives it a striking red to purplish-red or cranberry-red colour.
Although mostly found in massive form, where crystals are tightly intergrown into a large, shapeless mass, individual translucent crystals can be found, but are extremely rare.
Although found in a few countries, the finest grade kämmererite comes from Turkey.
These Kämmererite tumbled stones are highly polished and boast exceptional colour.
They're classed as large tumbled stones, but size does vary from piece to piece.
