Lepidolite is a lilac-gray or rose-coloured phyllosilicate mineral of the mica group that is a secondary source of lithium. Lepidolite is associated with other lithium-bearing minerals like spodumene in pegmatite bodies. It is one of the major sources of the rare alkali metals rubidium and cesium. In 1861 Robert Bunsen and Gustav Kirchhoff extracted 150 kg of lepidolite and yielded a few grams of rubidium salts for analysis, and therefore discovered the new element rubidium.
Within the metaphysical realm of minerals, Lepidolite aids in overcoming any kind of emotional or mental dependency, supporting in the release of addictions and complaints of all kinds, including anorexia. It encourages independence and self love and trust. Lepidolite combines its power of objectivity with direction and unimpeded communication, focusing on what is important and making it an excellent stone for business pursuits. Lepidolite is used as an ore to extract rare earth elements such as lithium, cesium, and rubidium. Lepidolite may be found in aplites associated with granite pegmatite. It is rarely found in hydrothermal veins and extremely rarely in granite contact zones. Lepidolite occurs in granite pegmatites, in some high-temperature quartz veins, greisens, and granites. Associated minerals include quartz, feldspar, spodumene, amblygonite, tourmaline, columbite, cassiterite, topaz, and beryl. Notable occurrences of Lepidolite can be found in Brazil; Ural Mountains, Russia; California; Tanco Mine, Bernic Lake, Manitoba, Canada; and Madagascar. Other than in the basic mineral form, lepidolite can be found in three distinct varieties:
