Fluorite with Calcite    Cave-In-Rock, Hardin County Illinois.  Ex. Harold L. Dibble collection.  This piece is a nice little specimen that measures 3.9 x 3.8 x 1.6 cm.  Back is crystallized, too.  Only minor edge contacts.  Some cube modifications by octahedrons.  Surfaces are stepped and cores are yellow.  Center has a small, healed, etched region where there was once an attachment or more likely a small loosely attached crystal.  Nice piece.  $45
