I. The Metaphysical Reading
How the stone has been held.
Muscovite is worked with as a stone of reflection, self-recognition and problem-solving. Its perfect basal cleavage into thin sheets is read as an image of the mind separating tangled situations into clear, workable layers.

II. The Scientific Reading
What the lattice actually does.
Muscovite is the most common member of the mica group, a potassium aluminum silicate with perfect basal cleavage that splits into thin, transparent, elastic sheets. It occurs widely in granitic and pegmatitic rocks and in low- to medium-grade metamorphic rocks such as schist and gneiss.
