Physical properties
Hardness: 2.5-4 (Lepidolite) / 7-7.5 (Tourmaline); Color: Pale lavender, violet-gray, and pink spots in white/translucent matrix; Luster: Vitreous to pearly; Crystal structure: Monoclinic (Lepidolite) and Trigonal (Tourmaline).
Formation & geological history
Formed in late-stage granitic pegmatites through hydrothermal processes. Lepidolite is a primary source of lithium, while the pink tourmaline (rubellite) crystallizes as a silicate mineral in these lithium-rich environments.
Uses & applications
Predominantly used as a source of lithium for batteries and glass, though polished specimens like this 'tower' are used for decorative purposes, meditation aids, and metaphysical crystal collecting.
Geological facts
Lepidolite was originally named lilacite because of its color. It is the most common lithium-bearing mineral on Earth. When found with pink tourmaline, it creates a striking aesthetic highly desired by collectors.
Field identification & locations
Identify by its distinct lilac-purple color and sparkly micaceous sheen. Found commonly in Brazil, Madagascar, and the United States (San Diego County, California). Look for the combination of purple mica sheets and pink crystalline inclusions.
