This is a cut section of a colorful rock material of bluish-brown Triphylite from the New Hampshire area.  The mine number is not available for this specimen, so it could have come from any of the Palermo mines.  Superb example specimen professionally prepared and in perfect condition.

Name: Triphylite
Specimen Size:  Large Cabinet-Sized
Dimensions:  111x67x35 mm /  4.4x2.6x1.4 inches

This is a specimen of Star Mica or Muscovite and Quartz cluster.  These clusters show crystals that grow in sheets or book formations.  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.
