One of our larger available Muscovite specimens, this piece consists of a matrix of white, semicrystalline albite that houses several black tourmaline crystals, tiny crystals of either apatite or beryl, and dozens of large, well-formed books of brownish Muscovite. These books range from 3 mm to over 1" (2.5 cm) in diameter. They are in relatively good condition, though many of the more exposed books have damaged edges. All show good hexagonal tabular form, a pearly luster, and dim translucence. There is a lot of Muscovite in this specimen!
