Fichtelite is a rare white mineral found in fossilized wood from Bavaria. It crystallizes in the monocliniccrystal 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. Three small ammonite fossils, each approximately 1. ...
