Lepidolite is a lilac to lavender-colored lithium mica mineral that belongs to the mica group, scientifically classified as potassium lithium aluminum silicate hydroxide fluoride with the highest natural lithium content of any mineral. This soft, flaky mineral forms in granite pegmatites and is prized for its soothing pastel colors and distinctive pearly to vitreous luster that creates a gentle, calming appearance. Lepidolite's high lithium content, the same element used in mood-stabilizing medications, has earned it recognition as nature's "peace stone" among crystal enthusiasts who value its reportedly calming energetic properties.
- Color range: Soft lilac and lavender to deeper purple; occasionally found in pink, white, or gray varieties with subtle color variations
- Sizes: Available from small tumbled stones (1-2cm) to large specimen pieces (several inches); massive varieties suitable for carving and cabochons
- Shapes: Most commonly found as raw specimens, tumbled stones, and cabochons; the flaky nature makes faceting challenging but possible
- Origin: Primarily Brazil, Madagascar, Russia, and California; finest purple specimens typically come from Brazilian pegmatite deposits
- Hardness: 2.5 to 3 on Mohs scale, very soft and requiring protective settings; the flaky structure makes it fragile for jewelry use
- Luster: Pearly to vitreous with a distinctive soft glow; the mica structure creates subtle light reflection across cleavage planes
- Cleavage: Perfect cleavage in one direction due to mica structure; can split into thin, flexible sheets
- Lithium content: Highest natural lithium concentration of any mineral, contributing to its reputation for calming properties
