Specimen of Star Mica or Muscovite with A Grade Cathedral Quartz cluster mined in Minas Gerais, Brazil. The specimen is mounted on museum putty so it can be carefully taken off if desired.  Measurements with mount are 1.5 inch high X 1.5 inches long.

It is silvery gold with good transparency when held up to the light. The name Muscovite comes from the term Muscovy Glass which was a name for the thick sheets of Mica used as a substitute for glass Russia. The name Mica is derived from the Greek word that means to split.

On this nice specimen, the matrix faces are covered with beautiful golden yellow point stars of muscovite mica, a typical shape for this rare mica formation. The stars are the result of twinning; the points show a bit of wear but this does not detract from the beauty of such a piece.
