Calcite    Mina Chiquitina, Chihuahua, Mexico.  Ex. Harold L. Dibble collection.  A neat calcite measuring 8 x 6.5 x 5 cm with large crystals in a divergent grouping.  The crystal are multiply-terminated and stepped in form.  Nicely translucent and of good luster.  Only damage is one broke crystal on backside of specimen.  Views nicely from all directions (except back and that view isn't bad either).  Nicely priced....  $90
