OKJ-955     Fluorite with Barite and Chalcopyrite      Spar Mountain Area, Cave-In-Rock, Illinois.  Ex. James Turek collection.   This fine plate of fluorites is very aesthetic sporting well formed cubes to .8 cm on edge.  The cubes are yellow in central regions of the piece and light purple as you approach the edge of the specimen.  They have beautiful purple phantoms that are paper thin, lots of chalcopyrites as inclusions and on their surfaces, and fantastic luster.  There is only very minor  chipping on a couple of fluorites and the piece has only one edge showing any attachment.  This makes everything you view, front, back, edges, totally mineralized.  It measures 7.4 x 7 x 2 cm and allows lots of light through it for a very attractive display.  A couple diamond shaped barites of a light gold color add a bit more diversity.  A very fine piece at a reasonable price.   $140

OKH-555

OKH-555    Calcite, Pyrite and Marcasite      Conco Mine, North Aurora, Kane County, Illinois.  Collected by Jared T. Freiburg.  A single pocket find that was harvested just prior to the 2011 Tucson show.  Truly new material!  Selective face coatings make some areas of the crystals look silky while others have the highest, glassy luster anyone could ask for in a calcite.  Reminiscent of the Brushy Creek material but finer.  The marcasite and pyrite are brightly metallic inclusions that sometimes zone as phantoms.  Really nice new stuff.  This cluster measures 11.2 x 7.5 and is a thin plate of well formed, damage free crystals to over 3 cm each.  Some are double terminated but most are single terminated.  Very fine example that is not quite as high in luster as some of the very best from the find.  No damage.    $75
