Historically, this area has produced many of the finest North American mineral specimens known.  Once common, quality specimens from Illinois have become rare and highly desirable.  Damage free specimens have always been uncommon and difficult to obtain. 

 

 

OKH-725

OKH-725    Fluorite with Calcite    RESERVED      Rosiclare Level, Denton Mine, Harris District, Illinois.  Ex. Paul and Dawne Dunning Collection.  An interesting specimen showing highly etched yellow fluorite capped by a later overgrowth of blue fluorite.  No damage to these regrown and etched surfaces.  Moderate luster.  9.8 x 7.2 x 5 cm.  Sits great on a flat base.  Views nicely from all sides.  This is a great piece for the fluorite specialist!  Priced to move.  $190

 

 

 

 

 

 

OKH-615

OKH-615     Calcite on Fluorite   Cave-In-Rock, Illinois.  Paul and Dawne Dunning Collection.  This specimen is composed of bright yellow fluorite, healed on all sides except base, coated by single and double terminated calcites.  7 x 6.1 x 4.5 cm overall.  After close inspection I find a few, but very few, cleaved calcites.  This specimen is an outstanding condition overall.  It is rare to see these types of calcites from this location in this high of a quality.  Usually the damage is far more extensive.  I know Iím dwelling on the specimenís condition but it is of course one of the most important aspects of any collectible mineral.  Rest assured that this is likely one of the finer calcites on fluorites that one could find in this day and age from Illinois.  $250

 

 

 

 

 

 

OKH-603

OKH-603    Calcite    Cave-In-Rock, Illinois.  Paul and Dawne Dunning Collection.  Circ. 1979.  This attractive display piece is a cabinet sized specimen measuring 11 x 9.6 x 5 cm.  Central to the display is a 6.6 cm calcite.  This specimen is very clean damage wise.  It is crystallized on the back but that area does show damage.  A frontal view makes this a spotless display specimen.  The luster is moderate and the crystals show good form and interesting surface features.  This is one of the nicer Cave-In-Rock calcites I have seen.  $185

 

 

 

 

 

 

OKH-604

OKH-604    Fluorite and Calcite    Roseclaire, Illinois.  Paul and Dawne Dunning Collection.  Circ. 1979.  This specimen is composed of cubes to 3.5 cm on edge.  The specimen measures 7.2 x 5.4 x 5.9 cm.  The color and luster are very desirable and most surfaces where they were broken in-situ are healed.  The phantoms are very nice, purple over yellow and the luster is high.  There are several small areas where damage has occurred so this specimen will not break the bank.  Still a very respectable display specimen. $65

 

 

 

 

 

 

OKH-580

OKH-580      Fluorite and Calcite     Cave-In-Rock, Illinois.  Ex.  Paul and Dawne Dunning Collection.   Several interlocking cubes with the most dominant one measuring 2.5 cm on edge.  The color is a rich purple but internally the cores are yellow.  The surfaces appear to have very low profile overgrowths by texahexahedral forms.  Calcite search gemmy and beautifully formed in most cases a deep rich yellow.  The specimen is basically a floater with a couple minor attachment points.  Some Styrofoam still attached to back that would be easy to remove.  The overall dimensions of the specimen are 3.2 x 3 x 2.8 cm.  This is a highly aesthetic though small example. A desirable high luster interesting and colorful specimen.  $320

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
