Physical properties

Formation & geological history

Formed in granitic pegmatites and high-temperature hydrothermal veins. It is a secondary mineral of late-stage crystallization in lithium-bearing igneous environments.

Uses & applications

Used as a minor ore of lithium, in the manufacture of glass and ceramics to increase resistance to heat, and as a popular semi-precious stone for carvings and metaphysical jewelry.

Geological facts

Lepidolite was originally named 'lilalite' after its lavender color. It is one of the world's most common sources of the rare alkali metal rubidium and is often referred to as a 'stone of transition' in holistic circles.

Field identification & locations

Identify by its light pink/purple color and micaceous (scaly) texture which catch the light. It is commonly found in Brazil, Canada, Madagascar, and the United States (Maine, California). Focus on the lithium-rich zones of pegmatite dikes.
