Pink Lepidolite

Lepidolite (K(Li,Al)3(Al,Si,Rb)4O10(F,OH)2)

Rock Type: mineral

Pink Lepidolite

Physical Properties

Hardness: 2.5-3.5 on Mohs scale; Color: Pink, lilac, or purplish-gray; Luster: Pearly to Vitreous; Crystal Structure: Monoclinic; Cleavage: Perfect basal (micaceous sheets); Specific Gravity: 2.8-2.9

Formation & Geological History

Formed primarily in lithium-bearing granitic pegmatites. It is often associated with other lithium minerals like spodumene and tourmaline. It typically forms in the late stages of magmatic crystallization.

Uses & Applications

A major source of the rare element lithium. Also used in glass-making, ceramics, and as a popular gemstone for bead jewelry and specimen collecting due to its aesthetic pink color.

Geological Facts

Lepidolite was originally named 'lilalite' because of its lavender color. It is a secondary source of rubidium and is often used by metaphysical collectors as a 'stone of transition' due to its high lithium content.

Field Identification & Locations

Identify by its distinct micaceous (sheet-like) structure and pinkish-purple color. Found in pegmatite fields globally, notably in Brazil, Madagascar, and the United States (San Diego County, California and Maine).
