Formation & geological history

Formed primarily in lithium-bearing granitic pegmatites. It is often found associated with other lithium minerals like spodumene and tourmaline. Commonly associated with the late stages of magmatic crystallization.

Uses & applications

Primary source of the rare alkali metal lithium; also used as a decorative stone, in jewelry (as cabochons), and highly valued by mineral collectors and metaphysical practitioners.

Geological facts

Lepidolite is the most common lithium-bearing mineral on Earth. Its name is derived from the Greek word 'lepidos' for scale, referring to its scaly appearance caused by flakes of mica.

Field identification & locations

Identify in the field by its distinct lilac to pink color, micaceous (sheety) cleavage, and low hardness (can be scratched by a copper penny). Common locations include Brazil, Canada (Manitoba), and the USA (California and Maine).
