Physical properties

Hardness: 2.5-3 (Lepidolite) to 7 (Quartz); Color: Violet, lilac, or pink mixed with white/clear; Luster: Pearly to vitreous; Crystal structure: Monoclinic/Hexagonal; Cleavage: Perfect basal (mica areas).

Formation & geological history

Formed in granitic pegmatites where high concentrations of lithium are present. Usually occurs in late-stage magmatic crystallization. Found in areas like Brazil, Madagascar, and the USA.

Uses & applications

Used as a minor source of lithium, for lapidary work (towers, beads, carvings), and highly valued in the metaphysical community as a 'stone of transition'.

Geological facts

Lepidolite is the most common lithium-bearing mineral. Its purple color is caused by trace amounts of manganese. This specific specimen is a 'tower' or 'point' that has been cut and polished into a decorative shape.

Field identification & locations

Identify by its distinctive lilac/purple color and micaceous (shimmery) flakes often suspended within white quartz. It is much softer than amethyst and often has a sparkly, layered appearance.
