Physical properties

Formation & geological history

Formed in high-temperature igneous environments like granite pegmatites. It is a secondary mineral of late-stage crystallization in lithium-rich ore deposits.

Uses & applications

Major source of lithium; used in glass and ceramic glazes. Used as a semi-precious stone for carvings, beads, and decorative obelisks. Popular among collectors for its calming aesthetic.

Geological facts

Lepidolite is one of the major sources of the rare alkali metals rubidium and cesium. It is often called the 'peace stone' or 'grandmother stone' in metaphysical circles due to its high lithium content.

Field identification & locations

Identify by the distinct lilac/purple color and pearly sheen. It can often be scratched with a penny, though quartz inclusions provide higher local hardness. Common in Brazil, Russia, and Madagascar.
