OKP-325

OKP-325      Wulfenite and Mimetite      Los Lamento Mountains, Chihuahua, Mexico.  Ex. Caroline Les collection.  This specimen is a very high luster example of the classic Los Lamentos material, however the crystals are very small and transparent.  The piece measures 8.5 x 7 x 6 cm overall.  There is only one tiny spot with a couple of missing crystals.  I think this damage is impossible to find without using magnification and it is well to the side.  Crystallization on back to but poorer in quality.  All views are nice.  Comes with a custom engraved acrylic base.  $600

 

 

 

 

 

OKP-326

OKP-326    Wulfenite     Mammoth Mine, Tiger, Arizona.  Ex. Caroline Les collection.  This palte of crystals measures 7.3 x 5 x 1.8 cm.  The specimen is composed of tightly interlocked, bright orange, transparent to translucent crystals of good size.  One tiny chip seen with magnification.  Very clean overall.  an excellent quality piece for the location.  Comes with a custom engraved acrylic base.    $500

 

 

 

 

 

OKO-714

OKO-714      Calcite, Quartz, Dolomite and Sulfide     Cumbria, England.  Ex. Bill Metropolis. This specimen is a plate that measures 9.5 x 7.4 x 2 cm.  It has "bogotá style" calcites to 2 cm each on lustrous, clear quartz with small clusters of the other minerals.  The sulfide is likely pyrite. No damage and it is crystallized on backside, as well.  $95

 

 

 

 

 

OKO-715

OKO-715     Bournnonite, Pyrite, Quartz       Pachapaqui District, Bolognesi Province, Ancash Department, Peru.  Ex. Bill Metropolis.  This is a nice miniature sized example of this classic material.  It measures 6.2 x 3.7 x 2 cm and is coated on one side by attractive prismatic bournonites.  Slightly domical form gives it good views from all sides.  Damage-free.  Could use a good cleaning but otherwise a fantastic specimen.  $175

 

 

 

 

 

OKO-716

OKO-716      Dolomite     Oberdorf, Austria.  Ex. Bill Metropolis.  Here is an attractive, bright white plate of small stalactite like stacks of dolomite crystals on a fully crystallized matrix of dolomite.  The piece measures 12 x 8.8 x 3.1 cm and is crystallized on the back, too (no stalactite like forms, however). Interesting and attractive specimen.  No damage.  $75

 

 

 

 

 

OKN-899

Color is actually a light blue NOT light purple.

OKN-899    Fluorite    Walworth Quarry, Walworth, New York.  Collected by Michael and Jay Walter.  This is a very large crystal that measures 4.6 x 4 x 3 cm.  It is not a full cube but it is complete, as found.  Cleaved on bottom with some dolomite matrix remaining attached.  All sides, other than base, are complete but vary in their luster.  Some faces are etched and others glassy smooth.  Sits nicely ad displays well from any direction.  Better in-hand than seen in the photos.  Lots of gemmy regions, few internal fractures, so it is certainly facet grade material.  Very minor edge chatter visible with magnification (tough to see even in blown up images).  This is a fine, desirable example of material that is seldom available in specimens larger than thumbnail sizes.  $600

 

 

 

 

 

OKN-900

OKN-900    Fluorite    Walworth Quarry, Walworth, New York.  Collected by Michael and Jay Walter.  This is one of the nicest thumbnail sized examples of this material that we have had in years.  Dolomite attachments on base and back make it challenging to show the clarity of this fine piece in the images.  It is glassy on all surfaces, shows some stepped growth and has only one internal flaw running parallel and along matrix.  Impressive in-hand.  One very tiny rub can be placed to back.   2.1 cm on edge.  3 x 3 x 2 in longest dimensions.  Will fit in a 1" x 1" for competition.  A very fine piece!  $450

 

 

 

 

 

 

OKN-901

OKN-901    Fluorite    Walworth Quarry, Walworth, New York.  Collected by Michael and Jay Walter.  This piece measures 3 x 2.8 x 1.8 cm (crystal is 1.7 cm on edge).  It has surfaces that are glassy and others that are frosted from contacts.  These contacts are casts after what must have been anhydrite or maybe celestine.  Transparent except at the small area of base where it was on matrix. Minor chipping as seen in image.  Overall condition is good.  $150

 

 

 

 

 

 

OKN-902

OKN-902      Quartz Faden    Rt. #55 Road Cut, Windsor, Quebec, Canada.  Ex. Dr. Steve Chamberlain collection.  Fadens are very rare from this location with only a few known.  It is the only one I have seen and I have inspected many thousands of specimens from this important locale.  This is a competition grade TN sized piece that measures 3.4 x 2 x 1 cm.  There is minor albite (white twinned crystals) at the base of the piece and a contact so small that even with close inspection it looks like a floater.  No damage.  $300

 

 

 

 

 

OKN-904

OKN-904    Vesuvianite, Grossular, Diopside     York River Skarn Zone, near Bancroft, Ontario, Canada.  Collected by Michael and Jay Walter. These vesuvianites may not appear overly impressive to those unfamiliar with this long closed location, but they are!  This species is normally only found in crystals the size of grains of salt.  These are up to a cm each, have unusually high luster, and are perfectly formed.  All the crystals, including the cinnamon colored garnets are damage-free.  The piece measures 6.9 x 5.7 x 2.8 cm.  It is the finest example we found in several years of extensive collecting in the mid-1990's.  I have never seen a finer example.  $1,500

 

 

 

 

 

OKN-905

OKN-905     Copper and Silver Nugget ("Half-Breed)     Houghton, Michigan.  Ex. John Davis collection.  This nugget is 5.5 x 3.6 x 1.5 cm and is mostly composed of silver (normally they are dominated by the copper).  There is no damage to the piece and it has a nice, classic, patina.  This is nicely priced at $195

 

 

 

 

 

OKN-906

OKN-906     Copper and Silver Nugget ("Half-Breed)     Houghton, Michigan.  Ex. John Davis collection.  This nugget is 5.8 x 4.4 x 2 cm.  There is no damage to the piece and it has a nice, classic, patina.  $95

 

 

 

 

 

OKN-907

OKN-907     Copper and Silver Nugget ("Half-Breed)     Houghton, Michigan.  Ex. John Davis collection.  This nugget is 4.3 x 3.4 x 1.6 cm.  There is no damage to the piece and it has a nice, classic, patina.  $75

 

 

 

 

 

OKN-908

OKN-908     Weloganite, Calcite, and Quartz   Francon Quarry, Montreal, Quebec, Canada.  Ex. John Davis collection.  This fine example was likely self collected by John during the times when this now closed location was a common collecting site for clubs from the U.S. and Canada.  It is the finest piece of its kind from his collection and sports a 2 cm, stocky weloganite crystal well placed among the calcite and quartz.  It displays beautifully however I have left it mounted in the perky box for shipping.  No damage  This is very desirable material when found in crystals this large and fine.  $500

 

 

 

 

OKN-909

OKN-909     Weloganite, Calcite, and Quartz   Francon Quarry, Montreal, Quebec, Canada.  Ex. John Davis collection.  This is a repaired specimen (one well concealed repair with B-72) that is a huge, complex crystal measuring 4.4 x 2.5 x 2.  There are a couple of harsh contacts, otherwise in good condition.  If you like large this is a nice choice, for this rarely large, species.  $275

 

 

 

 

 

OKN-910

OKN-910      Uraninite     Cardiff Mine, Bancroft, Ontario, Canada.  Ex. John Davis collection.  A slightly radioactive crystal that measures .4 cm on edge.  The crystal is gray and embedded in this grainy marble matrix, as seen.  4.8 x 3.8 x 2.8 cm overall.  No damage.  $75

 

 

 

 

 

OKN-911

OKN-911      Rhodochrosite, Calcite, Quartz, Pyrite    RESERVED    American Tunnel, Silverton, Colorado.  Ex. John Davis collection.  This might just be he brightest, most colorful example of this material I have carried.  I've had lots of them in the past but this one has lustrous examples of all the species mentioned in well formed crystals.  The piece measures 5.8 x 3.8 x 3.2.  his damage free specimen is a fine, well priced, Colorado classic.  $195

 

 

 

 

 

OKN-912

Back shows tabs of albite growing in epitaxy with twinned surfaces.

Top view of orthoclase twin plane.

OKN-912      Albite on Orthoclase     Organ Mountains, Dona Ana County, New Mexico.  Ex. Harold L. Dibble collection.  This miniature is certainly the finest of its size that I have seen.  The three primary orthoclase crystals are all twinned and in parallel growth.  The two biggest twins are, strangely enough, twinned in opposing directions!  The albite is in epitaxy on the orthoclase.  The base of the specimen is fully healed so this is a damage free floater.  Both feldspars are very nicely formed and more lustrous than they appear in the images.  7 x 5 x 3.7 cm overall.  I think you'd have to look long and hard to find a more interesting group of feldspar crystals!  $950
