Physical properties

Hardness: 2.5-3 (Lepidolite) to 7 (Quartz); Color: Purple, lilac, pinkish-grey; Luster: Pearly to vitreous; Crystal Structure: Monoclinic (Mica); Cleavage: Perfect basal.

Formation & geological history

Formed in granitic pegmatites during the final stages of magmatic crystallization. Higher concentrations of Lithium are required for its formation, often found in late-stage hydrothermal veins.

Uses & applications

Major source of lithium for batteries, glass making, and ceramics. Also used as a decorative stone, in lapidary work, and for metaphysical/collector purposes.

Geological facts

Lepidolite is the most common lithium-bearing mineral. It is often referred to as the 'peace stone' in New Age circles because it contains lithium, which is used medically to stabilize moods.

Field identification & locations

Identify by its distinctive lilac/purple color and micaceous 'glittery' flakes when broken. Commonly found in Brazil, Africa (Zimbabwe), and the USA (California and Maine).

Dark Igneous Rock (Likely Basalt or Diabase)

Basalt (extrusive igneous rock) or Diabase (intrusive igneous rock - also known as Dolerite), largely composed of plagioclase feldspar, pyroxene (augite), and sometimes olivine and amphibole. Exact mineralogy would require thin section analysis.
