Calcite pseudo. after Glauberite      Camp Verde, Yavapai County, Arizona.  Ex. Harold Dibble collection.  I don't seek these out to purchase as they are rather common specimens.  This one however is the nicest I've seen from any collection and it is a superior piece in all regards.  It is large measuring in at 7.9 x 4.7 x 4 cm.  Its form is very, very sharp for one of these and it is nicely translucent.  There is no damage to the piece, the coloration is attractive and their are no points of attachment.  Great piece!   $95
