Physical properties
Hardness: 2.5-4 for lepidolite and 7 for quartz, Color: Lilac to purple or pink, Luster: Vitreous to pearly, Crystal Structure: Monoclinic (lepidolite) and trigonal (quartz)
Formation & geological history
Formed in lithium-rich granitic pegmatites through hydrothermal activity and fractional crystallization
Uses & applications
Source of lithium metal, ornamental stone, crystal healing, and mineral specimen collecting
Geological facts
Lepidolite is a lithium-rich mica mineral that often imparts a distinct purple or pink coloration to pegmatite rocks and quartz matrices.
Field identification & locations
Identified by its distinctive purple/lilac color and micaceous or drusy quartz crystal texture. Commonly found in pegmatite-rich regions globally such as Brazil, Madagascar, and the USA.
