Lepidolite

colors: lilac (purpleish), colorless, yellow and grey

Mohs hardness: 2.5-3.5

A mica that contains lithium. Comes from the greek words “lepidos” which means scale and the word “lithos” which means stone. Like muscovite and biotite it is tabular, in that it has a tendency to split into flat pieces. (this is due to its crystal structure)
