Amphibole     Bear Lake Diggings, Maddill Road, Tory Hill, Ontario, Canada.  Collected by Michael Walter, 1990s.  I believe this is the accurate amphibole name at this time.  A decade ago these were being called fluor-magnesio-kataphotite.  In any case these are usually large clunky things that have little to no luster.  This one is an exceptional thumbnail sized piece that measures 2.9 x 2.5 x 2.3 cm.  It is a damage-free floater with excellent luster and form.  Truly exceptional for one of these specimens.  $140
