The word “mica” is derived from the Latin word micare, which means “shine.” This name was given to this group of minerals because they typically form in thin sheets and have a pearly luster.  Mica is said to have many beneficial properties, including amplifying energy, protecting from negative energy, and grounding oneself. It is also said to be helpful in reducing stress and promoting relaxation. Some people use mica in crystal healing practices, believing it can help balance the body’s energy fields and promote healing.
