It crystallizes in the Monoclinic System, typically forming tabular crystals, often in spheroidal masses; colors include colorless, white, gray, yellow, pink, and purple. It has a density of 2.80–3.30 g/cm³, a Mohs hardness of 2.5 to 4, and a refractive index ranging from 1.525–1.548, 1.551–1.585, to 1.554–1.587. Lepidolite belongs to the Mica Family.
