April I, 2013 Update

 

 

OKF-647

OKF-647     Aquamarine      Minas Gerais, Brazil.  Ex. Charles Daniels collection.  182 grams.  This large crystal is crudely double terminated and appears to have been, at one time, to have been a rider on the prism of a much larger aquamarine.   The blue is unusual and caused from iron (not chromium) in its composition.  10.7 x 4.6 x 2.6 cm.  Not of faceting quality but still a nice mineral specimen with good clarity but lots of  veils and internal interference.   Only $190

 

 

 

 

 

OKF-652

OKF-652       Calcite on Hematite     RESERVED    Stank Lorn Veiny, Lancashire, England.  Ex Dr. Steve Chamberlain collection.  A couple damaged points but overall in nice condition. Beautiful,  lustrous, complex calcites from a historic locale.   The large plate measures 8.6 x 8.4 x 3.9 cm.  A real find for $100

  

 

 

 

 

OKK-150

OKK-150     Grossular and Chlinopyroxene (likely diopside)    York River Skarn Zone, near Bancroft, Ontario, Canada.  Collected by Michael Walter, 1999.  Location is now a Provencal Park, collecting no longer allowed.  A fine miniature sized example with huge crystals for the location.  Normally they only reach a few millimeters in diameter but exceptional examples like this one can get much larger. This specimen is 4.8 x 4.1 x 4 cm.  The luster is good and the form , as well.  The white coatings seen in a couple places are brucite.  A few contacts but nothing major.  It would be hard to find a comparable miniature of this material in a museum or otherwise.  $190

 

 

 

 

 

OKK-151

OKK-151     Grossular and Chlinopyroxene (likely diopside)    York River Skarn Zone, near Bancroft, Ontario, Canada.  Collected by Michael Walter, 1999.  Location is now a Provencal Park, collecting no longer allowed.  A fine miniature sized example with huge crystals for the location.  Normally they only reach a few millimeters in diameter but exceptional examples like this one can get much larger.  This is a large crystal pair measuring 4.5 x 3.5 x 3.1 cm.  One face is damaged.  Excellent color and luster.  Minor vesuvianite.  Fantastic value here!    $35

 

 

 

 

OKK-152

OKK-152    Fluorite      Rosaclare, Illinois.  Previous New York State Museum collection.  Light purple on yellow, transparent cubes.  Good luster to this attractive piece.  The chalcopyrite inclusions are quite spectacular being well formed tetrahedrons suspended in transparent fluorite.  8.5 x 5.2 x 5.1 cm.  Very visible and aesthetic.  No damage to main body of piece, edge contacts.  $175

 

 

 

 

 

OKK-153

OKK-153     Quartz       Ron Coleman's Mine, near Hot Springs, Arkansas.  Collected by Michael Walter.  A big, displayable perfect point clear at tip down to milky at base.  Zero damage, sharp edges and point, extra faces (very small ones).   11.7 x 7.2 x 6.6 cm.  Excellent aesthetics all around.  $150

 

 

 

 

 

OKF-653

Back

OKF-653     Apophyllite on Stilbite       Ahmednagar, India.  An attractive bed of big stilbite blades has nicely double terminated attractive green apophyllites to 3.5 cm each.  White quartz stalactites at base add a bit of contrast.  Floater less very minor base contact.  Excellent views and complete mineralization all around.  Only damage is on base where one apophyllite is cleaved.  It will view as damage free from all sides including back as the cleaved crystal is hidden on base.  7.3 x 4.5 x 4.2 cm.  This is the desirable color for the species.  $200

 

 

 

 

 

OKK-154

OKK-154     Quartz, Feldspar and Goethite after Siderite         Zomba, Mali, Africa.  A good example measuring 8.5 x 5.5 x 5.2 cm overall with a large, chlorite included quartz standing up high off the top surface.  Good crystallization all around with only a couple tiny contacts to the quartz.  Most contacts now healed.  The quartz is very lustrous and well formed.  A nice value at $50
