Physical properties

Formation & geological history

Formed primarily in lithium-bearing granitic pegmatites. It is often associated with other lithium minerals like spodumene and tourmaline. It is found in geological settings where magma is rich in volatile elements.

Uses & applications

A major source of lithium used for batteries, glass, and ceramics. Also used as an ornamental stone and for jewelry in its more compact forms.

Geological facts

Lepidolite is often called the 'peace stone' or 'grandmother stone' in metaphysical circles because of its high lithium content, which is used in anti-anxiety medications. It is the most common lithium-bearing mineral.

Field identification & locations

Identify by its distinctive lilac-purple color and scaly, micaceous texture where small flakes catch the light. Found in Brazil, Madagascar, USA (California/Maine), and Canada. Collectors look for scaly mass aggregates which have a glittery appearance.
