Physical properties

Formation & geological history

Formed in granitic pegmatites. It is a secondary mineral often found associated with minerals like quartz, feldspar, and tourmaline. Commonly found in Mesozoic to Cenozoic geological formations.

Uses & applications

Major source of lithium; used in glass and ceramic production, lithium-ion batteries, and decorative carvings or jewelry. Popular in metaphysical crystal collecting.

Geological facts

Lepidolite is known as a 'stone of transition' and is naturally high in lithium, which is why it is often associated with emotional balance in holistic circles. It was first described in the 18th century.

Field identification & locations

Identify by its characteristic purplish-pink hue and soft, micaceous (glittery/flaky) texture. Often found in Brazil, Canada, Madagascar, and the USA (California and Maine). Collectors should look for vibrant purple color and 'point' polishing in specimens like this one.
