Clinozoisite    Keystone Traprock Quarry, Cornog, Chester County, PA.  Ex. Dr. Steve Chamberlain collection.  Prev. George Springs collection.  A fine transparent, double terminated crystal in quartz measuring 3.2 x 2.5 x 1.8 cm overall.  The crystal measures 2.3 cm and displays great.  A real find to get these Chester County minerals in modern times.  Chipping present being that it is broken free from massive quartz.  Looks good in-hand not in close-up photography.  Mounted in a perky box.  $75
