OKP-182

OKP-182     Calcite on Fluorite      Minerva #1 Mine, Cave-In-Rock, Hardin County, Illinois.  Ex. John Davis Collection.  This is a substantial specimen measuring in at 11.3 x 9.5 x 5 cm with cubes to almost 4 cm on edge.  The backside has blue cubes to 2 cm each, also with minor calcite.  Sorry, I took no photos of the back.  There is very minor rubbing as seen in images and a calcite shows damage.  In general the piece is in excellent condition and it will require magnification to note any issues.  Good luster and form to all the crystals.  An excellent example of this material. $350

 

 

 

 

OKN-811

TRUE color

OKN-811   Fluorite     Cave-In-Rock, Illinois.  Ex. Harold Dibble collection.   This is a large partial cube that measures 9.5 x 7.5 x 6 cm which would not show true color when I photographed it.  I've left these off color photos so it can be evaluated for shape and condition.   HOWEVER, it is BLUE with a minor purple core.  It has big, gemmy blue sections and a thin purple phantom.  The last photo was taken with my cell phone and does show how it looks in hand to the eye in any light.  There is chipping as can be seen but it is still a desirable example in a very desirable color.  $150

 

 

 

 

 

OKO-761

OKO-761     Fluorite     Rosiclare Level, Minerva #1 Mine, Ozark-Mahoning Company, Cave-In-Rock District, Illinois.  Ex. Harold L. Dibble collection.  This fluorite plate measures 20 x 13 x 5.2 cm overall with cubes having minor octahedral modifications to 7.3 cm on edge each.  It is a very uncommon copper color.  The luster is moderate but better than the images indicate.  The two cube corners on left have a couple layers of growth knocked off showing the zoned growth that resides below.  Great condition with healed edges and back.  Displays nicely.  $350

 

 

 

 

 

OKN-872

OKN-872     Barite on Fluorite     Cave-In-Rock, Illinois.  Ex. Paul and Dawne Dunning collection.  An attractive example measuring 7.2 x 6 x 4.4 cm.  A good specimen with some damage to the back corner of the large cube (a cleave).  Front view, however, is very nice showing lustrous white barites high on the nicely formed, moderately lustrous, cubes.  $70

 

 

 

 

 

OKM-162

OKM-162      Witherite and Fluorite      Cave-In-Rock, Illinois.  Ex. Harold L. Dibble.  A domical piece composed of several large intergrown crystals.  They have penetrated by a thin stringer of purple and blue fluorite.  Edge contacts but body of specimen is in nice condition.  8.5 x 7.2 x 3.2 cm.  Flat back (or base).  Nice example and I assume very fluorescent.  $240

 

 

 

 

 

OKO-781

Back

Sphalerite

OKO-781        Galena, Fluorite, Sphalerite       Cave-In-Rock, Illinois.  Ex. Harold L. Dibble.  One side is classic, patina rich galenas nd one dark sphalerite.  The other is small purple cubes of fluorite.  I'd call this a floater in that the small edge area that may once have been attached to wall rock has naturally healed.  Minor scuffing on a couple of the tiny fluorites probably because this heavy specimen has always been displayed with that side down.  7.4 x 5.2 x 4.1 cm.  The big galena is 3 cm on edge.  Nearly damage free.  Great surface texture and features.  This is a rather uncommonly rich galena for the Cave-In-Rock district.  $300

 

 

 

 

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      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

OKF-030

Nice phantoms

OKF-030    Fluorite      Denton Mine, Harden Co., Illinois.   What an impressive mineral specimen!  It is a piece I traded some great Canadian material many years ago.  It has remained in my collection and now is not something I collect any longer.  The primary cube measures an impressive 10.1 cm on edge.  It is gemmy with a rich yellow interior and a wonderful purple phantom.  Hoppered growth is attractive and interesting.  Displays well.  One corner cleave.  10.2 x 7.2 x 6.5 cm.  If you can live with the tiny corner being missing you can get this one at 1/3rd the price it would be at if totally damage free.  650$

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
