OKP-951     Calcite    Valentine Mine, Gouverneur Talc Company, Harrisville, Lewis County, New York.  Ex. John Davis collection.  The piece is dominated by a single crystal with good luster and translucence.  It has a hematite phantom that does not appear clearly in the images.  The piece measures 3.8 x 3.1 x 2.2 cm.  No damage.  $40

 

 

 

 

OKP-952

Base

OKP-952     Calcite    Valentine Mine, Gouverneur Talc Company, Harrisville, Lewis County, New York.  Ex.

OKP-953

OKP-953     Albite on Microcline on Quartz    Valentine Mine, Gouverneur Talc Company, Harrisville, Lewis County, New York.  Ex. John Davis collection.    The piece measures 4.2 x 2.5 x 2 cm.  These are very unusual forms for either variety of feldspar.  Bottom side is a cast after quartz and some areas having remaining quartz.  No damage.  This is an excellent quality and interesting example of this material that was very limited in quantity.  Well described in a Rock & Minerals article on the locality.  It does, barely, fit in a perky box.   $70

 

 

 

 

OKP-954

Base

OKP-954     Galena and Pyrite    Buick Mine, Bixby, Iron County, Missouri.  Ex. John Davis collection.  This beautiful piece has a large cube modified by octahedron that measures 2.2 cm on edge.  The piece measures 3 x 3 x 2.8 cm and sits nicely for display.  It is a damage-free floater with only a small contact from another crystal on base.  Catalog # is in a conspicuous location but can be easily removed.  It is a high quality, aesthetic example of these popular specimens.  $75

 

 

 

 

OKP-955

OKP-955     Galena and Pyrite on Dolomite   Buick Mine, Bixby, Iron County, Missouri.  Ex. John Davis collection.  This grouping shows octahedrons with minor cubic modifications.  There is a dusting of traditional pyrite crystals and bladed crystals with dolomite as a matrix.  The piece is free of any damage and measures 4.2 x 3 x 2.1 cm.  It displays better in views not shown and is a very fine example of this less common crystallography.   $75

 

 

 

 

OKP-957

OKP-957     Titanite     Rose Road Wollastonite Occurrence, Pitcairn, St. Lawrence County, New York.  Collected by Michael Walter.  I rarely let exceptionally fine specimens from St. Lawrence County go easily but I have a couple just like this one.  You will not find an example this good for sale as they are coveted by NY and Northeast US collectors.  This competitive grade TN measures 2.8 x 2.3 x 2.7 cm.  It is a rare (for this location) floater with excellent luster, form and Translucence/transparency.  Very, VERY minor crazing along an area of bottom edge visible with magnification.  It is a deep brown, purplish color.  Exceptional.  $275

 

 

 

 

OKP-958

OKP-958     Sphalerite     Walworth Quarry, Walworth, New York.  This location may be known for its fluorites but on occasion an okay sphalerite is found.  This sphalerite is the finest I have seen from the location in any size (they really don't get much bigger than this anyways).  It measures 2.2 x 2 x 1.8 cm.  The single large crystal is very nicely colored, translucent/transparent, damage-free, and has a better than normal luster.  Tiny dolomite crystals enhance the specimen and yes, it is twinned.  The color and transparency are better in person and much better when properly lit.  Keep in mind that I only do low light point and click photography for these postings.  $500

 

 

 

 

OKP-106

OKP-106     Betafite    Silver Crater Mine, near Bancroft, Ontario, Canada.  Ex. John Davis collection.  John field collected these crystals long ago when they were being found loose in the soil.  They are slightly radioactive and fine examples rarely seen in available in today's mineral market.  This one measures 2 x 1.5 x 1.2 cm and is a floater with one larger dominant crystal and small rider crystals on a couple of sides.  It has nice crisp form and shows one very, almost invisible, tiny chip on its base.  $65

 

 

 

 

OKP-107

OKP-107     Betafite and Quartz with Hematite     Silver Crater Mine, near Bancroft, Ontario, Canada.  Ex. John Davis collection.  John field collected these crystals long ago when they were being found loose in the soil.  They are slightly radioactive and fine examples rarely seen in available in today's mineral market.  This one measures 3.5 x 3.1 x 3 cm and is a matrix piece with beautifully formed crystals to 2.5 cm each.  The piece is very unusual in that it shows botryoidal hematite coatings in bubbles and layers on both the betafites and the clear quartz (which is barely visible.  No damage.  An exceptionally unusual and interesting specimen.  $350

OKQ-101

OKQ-101      Hematite     Thomas Range, Delta, Juab County, Utah.  Ex. Dr. Steve Chamberlain collection.  This is a 2.5 x 1.8 x .3 cm single hematite blade with a second generation of smaller crystals on it's surface.  The surfaces of the specular hematite are selectively coated by a brown earthy hematite and finally by an unknown white mineral.  No damage.   $50
