OKP-180

OKP-180     Calcite on Quartz     Valentine Mine, #4 Mine Gouverneur Talc Company, Harrisville, Lewis County, New York.  Ex. John Davis Collection.  This fist sized piece measures 10 x 9.6 x 7.7 cm.  There is a large, 4 cm, calcite near the top of the display face.  It has differing lusters on its faces that range from dull to bright satin like in appearance.  The pseudo cubic quartz is brighter than the images indicate, very high luster, but some faces are overcoated by hematite.  In-hand this is an attractive example of this uncommon material.  Lower part of specimen has crystals missing but the main crystals are in excellent condition.   $95

Back

OKP-181     Calcite on Quartz     Valentine Mine, #4 Mine Gouverneur Talc Company, Harrisville, Lewis County, New York.  Ex. John Davis Collection.  This piece is an exceptional example of this material: large, showy, with high luster pseudo cubic quartz crystals and nice calcite.  The piece measures 17.3 x 11.5 x 5.5 cm.  Like other specimen from this location it is more lustrous than the images indicate.  The calcite crystals overgrowing much of the pseudo cubic quartz are not lustrous.  This plate is showy and far better than most specimens seen from this small find.  The hematite phantoms and coatings created a nice contrast and coloration to the piece.  There is no damage but some edges of the plate show contact as would be expected.  $400

 

 

 

 

 

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
