Physical properties

Formation & geological history

Forms in granite pegmatites and high-temperature quartz veins, as well as in some greisens and hydrothermal veins where lithium-rich fluids crystallize.

Uses & applications

Primary ore of the alkali metal lithium, used in glass and ceramic manufacturing, and popular as a polished gemstone or metaphysical stone.

Geological facts

Lepidolite is known as a 'lithium mica' and its soft, flaky structure is characteristic of micas. Because of its lithium content, it is often associated with calming and balancing properties in metaphysical contexts.

Field identification & locations

Identified by its soft texture, perfect cleavage, and characteristic pinkish-purple or lilac color. Commonly found in major pegmatite deposits in Brazil, Madagascar, the United States (California), and Russia.
