Physical properties

Hardness: 2.5-4 (Mohs scale), Color: Pink, lilac, or purple, Luster: Vitreous to pearly, Crystal structure: Monoclinic (often found in micaceous masses), Cleavage: Perfect basal

Formation & geological history

Formed primarily in lithium-bearing granitic pegmatites. It is late-stage igneous mineral formed from fluids enriched in lithium and volatiles.

Uses & applications

Secondary source of lithium; used in jewelry as beads and cabochons, and as an ornamental stone or collector specimen. Lithium is used in batteries and glass production.

Geological facts

Lepidolite is often called the 'peace stone' or 'stone of transition' in metaphysical circles. It naturally contains trace amounts of rubidium and cesium.

Field identification & locations

Identify by its distinct purple to lilac color and micaceous (flaky) texture. In spherical forms like these, look for the 'sparkle' of mica flakes within the polish and its relatively low hardness compared to quartz.
