The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.
The word mica is derived from the Latin word mica, meaning a crumb, and probably influenced by micare, to glitter.
Mica assists in self-reflection and facilitates the acknowledgement and elimination of character traits that no longer serve one’s highest purpose. Mica is a helpful crystal tool as it helps one look at a situation in complete detail. Mica provides for growth and flexibility in all areas and supports the processing and release of painful feelings. Mica provides one with energy and purpose to move forward and appreciate the lessons and experiences in the past. Mica diminishes nervous energy, calms an overthinking mind while positively enhancing intellectual pursuits and mental situations.
