Physical properties

Hardness: 2.5-3.5 on Mohs scale; Color: Pink, lilac, or purple; Luster: Pearly to vitreous; Crystal Structure: Monoclinic; Cleavage: Perfect basal (micaceous); Specific Gravity: 2.8-2.9

Formation & geological history

Formed in late-stage crystallization of granite pegmatites, often associated with other lithium-bearing minerals like spodumene and tourmaline.

Uses & applications

A major source of lithium used in batteries and glass production; also used as an ornamental stone and for gemstone carving. Popular in the metaphysical community.

Geological facts

Lepidolite was originally named 'lilalite' because of its lavender color, but was later changed to lepidolite which comes from the Greek word 'lepidos' meaning scale, referring to its scaly appearance.

Field identification & locations

Identify in the field by its distinct pink/lilac color and micaceous 'scaly' cleavage. It is commonly found in Brazil, Canada, Madagascar, and the United States (California and Maine).
