Tourmaline and Quartz   Powers Farm, Pierrepont, St. Lawrence County, New York.  Collected by Michael Walter in 1990s.  This crystal is very atypical for the location in that it shows a moderate amount of prismatic development.  Crystals from this location are almost always equadimensional or slightly tabular.  Prismatic, strongly hemimorphic crystals like this one are probably only one in every 10,000.  The condition of this piece is great. The back view shows contact for the quartz but the tourmaline is fully formed having well-healed faces on the back and one area of contact seen at the top terminal area.  4 x 2.6 x 2.1 cm.  $95
