Lepidolite Mica Rich in Lithium
An unusually large piece of lepidolite mica from our collection of rocks and minerals. This piece stands without support but would be more secure if displayed on a small stand.
Lepidolite is a lithium-rich mineral widely used in industries around the world. Silvery inclusions resembling glitter shed easily. For this reason, mica should be handled as little as possible.
Lepidolite is part of the mica mineral group. There are thirty-seven varieties, the most common being muscovite and lepidolite.
Mica minerals are silicate minerals or sheet silicates because they form distinctive layers or sheets.
Mica flakes are used in almost all cosmetics. They add shimmer, lustre and sparkle and are also used where brightening or glow is needed. Mica is also used in skincare products and body lotions.
Some of the world's largest mica deposits are in one of the poorest regions of India and Madagascar. Mines are mostly unregulated, and child labour is common.
We only buy mica from the state of Minas Gerais in Brazil.
Although lithium is often believed to be the cause of the purplish-pink colour of lepidolite mica, it actually comes from impurities of manganese.
Mica is heat-resistant, soft, flaky and lightweight. The layers and flakes are flexible but break away very easily.
Lepidolite mica is a lustrous mineral that reflects light from every angle. However, its pearly to vitreous lustre is not easy to capture in a photo.
