WitrynaMica is a healing crystal that has been used for centuries to promote physical, mental, and spiritual well-being. This crystal is thought to be helpful in restoring balance and harmony and is believed to promote feelings of love, peace, and happiness. Mica is also said to be helpful in clearing negative energy and promoting positive energy. Geologists define schist as medium-grained metamorphic rock that shows well-developed schistosity. Schistosity is a thin layering of the rock produced by metamorphism (a foliation) that permits the rock to easily be split into flakes or slabs less than 5 to 10 millimeters (0.2 to 0.4 in) thick.
