Check this out from Wikipedia: Mica sheets are chemically inert, dielectric, elastic, flexible, hydrophilic, insulating, lightweight, platy, reflective, refractive, and resilient. Mica is stable when exposed to electricity, light, moisture, and extreme temperatures. It has superior electrical properties as an insulator and as a dielectric, and can support an electrostatic field while dissipating minimal energy in the form of heat; it can be split very thin (0.025 to 0.125 millimeters or thinner) while maintaining its electrical properties, has a high dielectric breakdown, is thermally stable to 932 °F. Muscovite, the principal mica used by the electrical industry, is used in capacitors that are ideal for high frequency and radio frequency. In stone medicine, mica is one of the most versatile stones in existence, capable of action in almost every category and function of clinical treatment and formulas. Because this is nature, no two minerals will be the same. Note that images showing several of each crystal pair are photographed to attempt to convey the range of color, detail and vibration possible in the crystal you are ordering through this listing. Allow yourself to be surprised by the unique minerals that come to you.
