Lepidolite
Lepidolite (K(Li,Al)3(Al,Si,Rb)4O10(F,OH)2)
Rock Type: mineral

Physical Properties
Hardness: 2.5-3.5 on Mohs scale; Color: Pink, lilac, to deep purple; Luster: Vitreous to pearly; Crystal Structure: Monoclinic (often massive or micaceous); Cleavage: Perfect basal.
Formation & Geological History
Formed primarily in lithium-bearing pegmatites (igneous rocks with large crystals) during the late stages of magma crystallization. It is an important ore of lithium and often occurs with tourmaline and amblygonite.
Uses & Applications
Used as a major source of lithium, which is used in rechargeable batteries, glass making, and ceramics. In the metaphysical and collecting world, it is popular for carvings, spheres, and jewelry.
Geological Facts
Lepidolite is often called the 'peace stone' or 'grandmother stone' in holistic circles because of its high lithium content, which is used in medicine to treat mood disorders.
Field Identification & Locations
Identify by its distinctive lilac/purple color and micaceous (sheet-like) structure. In carvings like the one shown, look for the 'sparkle' of tiny mica flakes. Commonly found in Brazil, Canada, and the USA (California and Maine).
