Physical properties

Hardness: 2.5-3 (Mohs scale), Color: Pink, lilac, to grayish-purple, Luster: Vitreous to pearly, Crystal Structure: Monoclinic (often found in micaceous masses), Cleavage: Perfect basal (micaceous)

Formation & geological history

Formed in granitic pegmatites where high concentrations of lithium are present. It is often found associated with other lithium-bearing minerals like spodumene, tourmaline, and amblygonite.

Uses & applications

Primary source of rare alkali metal lithium; also used in glass and ceramic production to inhibit heat expansion and as a decorative stone/crystal healing object.

Geological facts

Lepidolite is the most common lithium-bearing mineral and was first discovered in the 18th century. It is often referred to as the 'peace stone' in metaphysical circles due to its high lithium content, which is used in medical mood-stabilizing drugs.

Field identification & locations

Identify by its characteristic lilac/purple color and micaceous (flakey) structure. In this specific image, it has been cut and polished into a hexagonal point. Commonly found in Brazil, Canada, Madagascar, and Russia.
