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. 

 

 

OKO-702

OKO-702      Calcite with Pyrite and Marcasite      Conco Mine, North Aurora, Kane County, Illinois.  An impressive 20 x 19 x 10 cm piece with lots of crystallization on all sides.  Natural contacts are obvious.  Damage is very minimal for a piece of this size.  I can only find a couple cleave crystals on one end. This specimen has a nice high luster, better than most from the single pocket find.  I'm sorry, but my photographs and lighting fail to show the high luster that is present.  It is indicative of the finest material to come from the find.  An impressive grouping that will get looks in any collection.  $245

 

 

 

 

 

 

OKO-703

OKO-703      Calcite with Pyrite and Marcasite      Conco Mine, North Aurora, Kane County, Illinois.  An impressive 27 x 26 x 11 cm piece with lots of crystallization on front and sides sides.  the only damage is to only one crystal in the lower region of the piece.  Crystals to almost 4 cm each with outstanding sulfide phantoms.  This specimen has an excellent high luster, better than most from the single pocket find.  An impressive grouping that is very three dimensional.  It almost stands up on its own so will need very little assistance in order to display great.  All views except base and back are impressive.  I'm sorry, but my photographs and lighting fail to show the high luster that is present.  It is indicative of the finest material to come from the find.  This is a very fine example from a limited find.  $450

OKAA-016

OKAA-016     Calcite on Fluorite    Cave-In-Rock, Illinois.   Ex. Nancy Collins collection.  A huge, deep purple grouping of cubes measuring 21 x 14 x 12 cm.  The largest cubes are over 9 cm each.  Overall it is in good condition, not excellent but it displays very nicely.  The calcite overgrowths add some needed sparkle to these dark, translucent fluorites.  They coat most upper surfaces of the cubes and much of the back of the specimen.  Well crystallized all around less some backside contact.  A heavy substantial piece worthy of display.  Someone will love this specimen and it's low price.  Comes with engraved acrylic base.   $600

 

 

 

 

 

 

OKAA-004

OKAA-004   Calcite with Pyrite and Marcasite Inclusions   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.  No more of this material has been produced since.  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 6.5 x 6 x 4.7 cm and is a dome of well formed, damage free crystals to 2 cm each.  Some are double terminated but most are single terminated.  Very fine example with a custom engraved acrylic base.  No damage. $200
