This huge and gorgeous “book” of Golden Mica on a Quartz Matrix base is one of a kind! If you are a Mica lover, look no further. You have found your pot of gold. Literally! The Golden Mica shines and sparkles in the rays of the Sun. If you catch it at the right angle, it will almost blind you! This is an excellent example of how Mica grows naturally (called a “book” because the thin Mica layers resemble the pages of a book).
