Mar 02 2020 · Mica is among the minerals that tend to retain a sheen and glimmer in direct light. Along with being classified as a silicate it is also among minerals that exhibit monoclinic properties similar to that of crystals. Because mica has been found in a number of different types of rock formations the price for it is much lower than in times past.
