Physical properties
Hardness: 2.5-3 (Mohs). Color: Pink, lilac, or purple. Luster: Vitreous to pearly. Crystal structure: Monoclinic (mica group). Specific Gravity: 2.8-2.9. Distinctive micaceous cleavage.
Formation & geological history
Formed in granitic pegmatites, often associated with other lithium-bearing minerals like spodumene or tourmaline. It is a secondary source of lithium.
Uses & applications
Used as a source of lithium to manufacture glass and ceramics, as an ornamental stone for beads/jewelry, and highly valued by collectors for its color.
Geological facts
Lepidolite is known as the 'peace stone' in metaphysical circles due to its high lithium content, which is used medically to treat mood disorders. It often has tiny sparkling inclusions of mica.
Field identification & locations
Identified by its characteristic lavender/lilac color, softness, and micaceous (flaky) texture in raw forms. Commonly found in Brazil, Canada, Madagascar, and the USA.
