You can be my lucky star! This specimen is a very unusual formation of muscovite mica. Muscovite is an important rock-building mineral that is often found in granites. While the mineral may be common, this formation is quite rare. In this specimen, large clusters of muscovites have stacked together in a rare star formation. From Minas Gerais, Brazil
