Physical properties

Formation & geological history

Forms in lithium-rich granitic pegmatites during late-stage crystallization of granitic magmas, commonly in the Mesozoic to Cenozoic; exact age depends on locality.

Uses & applications

Collected as a colorful mineral and used historically as a minor lithium source; attractive polished pieces are used in cabochons and decorative objects, though it is too soft for durable jewelry.

Geological facts

Lepidolite commonly occurs with tourmaline, beryl, quartz, and feldspar, and its lilac color is associated with manganese. The image alone cannot confirm whether both fragments are lepidolite or a mixed pegmatite.

Field identification & locations

Look for glittering mica flakes, easy splitting into thin sheets, and a pale lilac/pink color; avoid confusing it with harder rose quartz or opaque rhodonite. Common localities include Brazil, Madagascar, Zimbabwe, and California.
