Lepidolite is a lilac to purple mineral belonging to the mica group. It is primarily composed of lithium, aluminum, and silicate, making it a significant source of lithium, which is used in batteries and other applications. Lepidolite often forms in pegmatitic rocks and can be found in various locations worldwide, including Brazil, Madagascar, and the United States. This mineral is known for its flaky texture and can exhibit a shimmering effect due to its layered structure. Lepidolite is also popular in the metaphysical community, where it is believed to promote emotional balance and reduce stress, although these claims are not scientifically validated.
