Fichtelite

Fichtelite is a rare white mineral found in fossilized wood from Bavaria. It crystallizes in the monoclinic crystal system. It is a cyclic hydrocarbon dimethyl-isopropyl-perhydropenanthrene, C19H34. It is very soft with a Mohs hardness of 1, the same as talc. Its specific gravity is very low at 1.032, just slightly more dense than water.

It was first described in 1841 and named for the location, Fichtelgebirge, Bavaria, Germany.
