Physical properties
Lepidolite has a Mohs hardness of 2.5 to 4, pink to purple color, pearly luster, and flaky micaceous cleavage. Quartz has a hardness of 7, vitreous luster, and conchoidal fracture.
Formation & geological history
Formed in lithium-rich pegmatites through late-stage magmatic crystallization and hydrothermal activity over millions of years.
Uses & applications
Primary ore for lithium extraction and collected as a decorative mineral specimen.
Geological facts
Lepidolite is one of the few abundant lithium-bearing minerals and is closely associated with rare-element pegmatites.
Field identification & locations
Identify by its distinctive lilac-pink color and soft, flaky mica sheets embedded within hard quartz matrix; found globally in pegmatite-rich regions like Brazil and the USA.
