Mica Meaning and Properties
Mica History
Mica is a natural stone with a vitreous to pearly luster, which forms in multiple distinct layers. Mica is actually a broad term that is attributed to more than 34 types of these layers. The most common form of mica is called muscovite, while other varieties include anandite, fuchsite and lepidolite. While mica has been found in various places around the world throughout history, it wasn't until the 19th century that the gem was given its name and mined for export. This stone is often ground up and used as a shimmering powder accent in jewelry and accessories, but mica is also used in makeup foundations and cement filler and as an insulator in electrical cables.
What are the Metaphysical Properties of Mica?
No doubt in part due to its shimmering, reflective properties, mica meaning is associated with helping individuals reflect on individual qualities. Mica is thought to help us recognize flaws without self-condemnation so we are able to effectively address negative personality traits. (After all, you can't change what you don't see.) According to metaphysical beliefs, mica is also used to reduce hostile or nervous energy. The gemstone mica is not a traditional birthstone but is most closely associated with the zodiac signs Aquarius and Virgo. Some say mica meaning is also connected to the heart chakra, while others believe that the pigment of the stone affects which chakra mica influences.
What is Mica Made From?
Mica is a type of silicate formed as paper-thin layers built upon each other in formations that include flat angular blades, rosettes or hexagonal columns. Mica is a metallic material since it contains reactive element metals like potassium, lithium and aluminium. For this reason, mica can feel cold to the touch. The gem mica is predominantly found in Brazil, Russia, Africa, India and Pakistan.

Designing with Mica
In jewelry-making, mica is most commonly found as a powder. This powder is used for creating colorful accents on polymer clay, resins and more. It is recommended to apply a clear top coat to prevent the pigment from wearing off over time. Natural mica can also be found as sheets that are sometimes used as a substitute for glass sheet, offering a vintage air to jewelry and décor designs since they give a slight sepia tone to materials they are placed on. Mica sheets can be easily ink-stamped, drilled, riveted and cut with scissors. Coated mica beads are sometimes mistaken for pyrite since they have an iridescent sheen over a dark grey-gold background. These tones are ideal for men's, women's and unisex jewelry designs. It is recommended to use mica sheet or beads in jewelry such as pendants and earrings rather than bracelets or other jewelry that can accidently receive impact such as from a countertop.
