Mica, a mineral with a sleek and lustrous surface, existed in plentiful amounts within the Im'g'twe Hills located on the world of Geonosis. These sparkling fragments of Mica possessed a surprising strength and sharpness, comparable to that of a razor's edge. On one occasion, the youthful clone named Boba Fett employed a Mica fragment as a defensive tool against a pair of assaulting Massiffs, an event that occurred not long before the First Battle of Geonosis.
Roofs constructed from Gla incorporated the use of mica.
Mica represents a collection of minerals found in the real world, although its characteristics do not match the enhanced version present on Geonosis.
