Fluororichterite      Wilberforce, Ontario, Canada.  Collected by Michael Walter, 1990s.  A tablet shaped, double terminated crystal of this rare mineral that measures 2.7 x 2.2 x 1 cm in edges.  Great luster and impeccable form.  This is an exceptional example.  One very small cleave on one corner is not distracting from this piece’s high quality.  $65
