|Colour:||Pink, light purple, ...||Hardness:||2½ - 3½|
|Name:||Named in 1792 by Martin Klaproth from the Greek words Lepidos for "scale" and Lithos for "stone".|
A mineral in the so-called Polylithionite-Trilithionite series.
The original lepidolite came from Rožná pegmatite, Žďár nad Sázavou, Vysočina Region, Moravia (Mähren; Maehren), Czech Republic.
