OKO-184     Quartz Scepter (variety Amethyst)    Pohndorf Amethyst Mine, Jefferson County, Montana.  Ex. Dr. Steve Chamberlain collection, circ. 1970s.  A wonderfully colorful amethyst with dark phantom.  Edge chatter on termination but still worth acquiring.  2.2 x 2 x 1.5 cm.  Nicely mounted in a perky box.  $40

OKO-187     Astrophyllite   Mont St-Hilaire, Quebec, Canada.  Ex. Dr. Steve Chamberlain collection.  3.4 x 1.7 x 1.7 cm grouping of fibrous, damage free crystals.  Attractive, lustrous, uncommon for the locale.  Mounted beautifully in a perky box.  $35

 

 

 

 

 

 

OKO-188

OKO-188    Fluorapatite    Rt. #55 Road Cut, near Windsor, Quebec, Canada.  Ex. Dr. Steve Chamberlain collection.  Collected in the 1980s, this was the rare species for the find.  Only a small handful ever found.  This is simply a representative of this rare material, not a world-class fluorapatite by any means. 1 x .8 x .6 cm specimen.  In good condition, but obviously small.  Pinker than the pic indicates.  $20

 

 

 

 

 

 

OKO-189

OKO-189   Stilbite on Quartz Cast after Laumontite    Upper New Street Quarry Patterson, New Jersey.  Ex. Dr. Steve Chamberlain collection. SPECIMEN CATALOGE # 2 out of approximately 45,000 specimens in his collection!!!  I believe #1 is a prehnite from this location that he has retained for memory's sake.    Yes, the second specimen in this now famous collection.  It was acquired from Dottie Herman in 1961.  It is a fine, damage free example of this material with a 3.5 cm bowtie of amber colored stilbite sitting upright on a bed of white quartz casts after laumontite.  Classic material common in that day.  3.7 x 2.7 x 2 cm overall.  Very nice and very cool provenance.   $100

 

 

 

 

 

 

OKO-191

OKO-191    Calcite Twin {01.8}    Medusa Quarry, York, York County, PA.  Ex. Dr. Steve Chamberlain collection, personally collected by him in 1963.  Two crystals beautifully twinned according to this rare (at least for this quarry) form.  Iridescent coating makes for an attractive thumbnail sized piece that measures 2.4 x 2 x 1.4 cm.  A great piece for a competition case on twinning.  One crystal missing in front view.  Back view is about the same for this piece.  $95

 

 

 

 

 

 

OKO-192

OKO-192     Aurichalcite on Calcite    Medusa Quarry, York, York County, PA.  Ex. Dr. Steve Chamberlain collection, personally collected by him in 1963.  I have to assume this is rare for the quarry in that I have never encountered it before.  Tine robin's egg blue balls on calcite make for a good contrast in this 1.9 x 1.8 x 1.6 cm piece.  No damage.  Displays nicely.   $45

 

 

 

 

 

 

OKO-193

OKO-193    Celestine    Lime City, Wood County, Ohio.   Ex.

OKO-194     Quartz     Resplendor, Minas Gerais, Brazil.  Ex. Dr. Steve Chamberlain collection.  A gemmy 2.5 x 1.1 x 1.1 cm crystal.  No damage, nice luster, mild smoky tint.  $20

 

 

 

 

 

OKO-195

OKO-195    Goethite pseudo after Pyrite    Mexico.  Ex. Dr. Steve Chamberlain collection.  Three examples, all floaters without damage up to 1.4 cm in diameter each.  These are “Iron Cross” twins and nice examples of them.  Someone will probably split up this set and do well selling them.  $50

 

 

 

 

 

 

OKO-196

OKO-196    Stilbite    Road Cut near Thomaston Dam, Connecticut.  Ex. Dr. Steve Chamberlain collection.  A fine crystal (minor bowtie form) crystal on matrix.  No damage.  Very uncommon material.  Classic East Coast specimen.  $50

OKO-197

OKO-197     Chalcopyrite   Groundhog Mine, Vanadium, Grant County, New Mexico.  Ex.

OKO-198

OKO-198    Chalcopyrite   French Creek Mine, St. Peters, Chester County, PA.  Ex. Dr. Steve Chamberlain collection.  An old timer that looks pretty crude to most.  Some old damage, highly oxidized.  3.5 x 2.2 x 1.4 cm.  Mounted in a perky box.  What makes the piece worth listing here is that the crystals are mostly spinel law twins.  $25

 

 

 

 

 

 

OKO-199

OKO-199     Allanite    Yates Mine, Otter Lake, Quebec, Canada.  Ex. Dr. Steve Chamberlain collection.  A nice, large, very flat crystal measuring 3.6 x 2.5 x .3 cm.  One very tiny rub on a corner.  Overall excellent condition for one of these.  Field collected by Dr. George Robinson.  $50
