lepidoliitti

Lepidolite is a lithium- and aluminum-containing mica mineral. It is a phyllosilicate mineral belonging to the mica group. Lepidolite is typically found in granite pegmatites and other igneous rocks. It is known for its distinctive color, which can range from pale pink and lilac to deep purple and gray. This coloration is often attributed to the presence of manganese and trace amounts of other elements.

The mineral's name is derived from the Greek word "lepis," meaning scale, referring to its flaky structure. Lepidolite is a relatively soft mineral, with a Mohs hardness of 2.5 to 4, and exhibits perfect basal cleavage, meaning it splits easily into thin, flexible sheets. Its luster is vitreous to pearly.

Historically, lepidolite has been associated with various metaphysical properties, often linked to calming, stress relief, and emotional balance. It is sometimes used in jewelry and decorative objects, although its softness makes it less suitable for high-wear applications. Commercially, lepidolite is a minor source of lithium, which is a valuable element used in batteries, ceramics, and pharmaceuticals. The extraction of lithium from lepidolite can be complex and is not as common as from other lithium-bearing minerals like spodumene.
