Physical properties
Hardness: 2.5–4, Color: Violet, lilac, deep pink to purple, Luster: Vitreous to pearly, Crystal Structure: Monoclinic, Cleavage: Perfect basal (micaceous)
Formation & geological history
Formed in lithium-rich granite pegmatites via magmatic differentiation and hydrothermal processes.
Uses & applications
Major ore of lithium, gemstone, polished tumbled stones for lapidary art, spiritual healing, and mineral collecting.
Geological facts
Lepidolite is one of the primary sources of lithium, which is heavily used in modern rechargeable batteries. It often displays a distinct silvery shimmer due to its mica flake structure.
Field identification & locations
Identified by its distinctive purple/lilac hue paired with pearly or micaceous sheen. Commonly found in pegmatite deposits in Brazil, Madagascar, Russia, and the United States (California, Maine).
