Quartz and Other Mineral Specimens from the Valentine Mine

Harrisville, St. Lawrence County, New York

 

 

Quartz specimens from the Valentine Mine in Harrisville are among some of New York States most aesthetic specimens.    

                                                                                                                                     Quartz with Hematite and Tremolite Inclusions

      

Several years ago Rocks and Minerals Magazine published and article on the Valentine Mine, also known as the number 4 Mine of Gouverneur Talc Company, in Harrisville, NY.  This small occurrence has produced some of the most unusual and aesthetic minerals found in New York State. 

This mine has produced some of the nicest and most interesting quartz to come from New York State in recent years.  Red hematite inclusions are certainly interesting but add acicular probably tremolite needles and you end up with some truly unique specimens.  Oh, by the way, most of the terminations are pseudocubic in form.  The calcites are also fantastic.  Donít forget the unusual feldspars as well.  There is a great Rocks and Minerals article on this mine.   

 

 

 

OKO-548

OKO-548        Quartz       Valentine Mine, Harrisville, Lewis County, New York.  Ex. Jay Walter collection.  This is an attractive example of 'harlequin" quartz.  It measures 9.8 x 7 x 5 cm and is composed of singly and doubly-terminated points with many attractive phantoms.  Pseudo-cubic form to the crystals is noticeable on each termination (only three faces showing at 90 degree angles).  There are a couple broken points but they are not distracting.  A very nice piece.  $140

 

 

 

 

 

OKO-544        Quartz       Valentine Mine, Harrisville, Lewis County, New York.  Ex.

OKO-544        Quartz       Valentine Mine, Harrisville, Lewis County, New York.  Ex. Jay Walter collection.  This damage-free cluster measures 7 x 4.8 x 3.4 cm.  Very fine hematite inclusions and phantoms of red and silver color.  I did not clean this one before photographing so it appears dusty looking (but will clean easily).  The piece sits on edge for display.  Pseudo-cubic form to the crystals is noticeable on each termination (only three faces showing at 90 degree angles).  This is a nicely sculpted, high luster example of what is commonly called "harlequin quartz".  $350

OKN-887

OKN-887      Quartz, Calcite, Hematite       Valentine Mine, Gouverneur Talc #4 Mine, Harrisville, Lewis County, New York.  Ex.

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

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
