OKI-192	Back	Top calcites

OKI-192    Calcite on Chalcocite    Bristol Copper Mine, Bristol, Hartford Co., Connecticut.  Ex. Dr. Steve Chamberlain Collection, prev. Dick Kelley and University of Rochester Collections.  This is certainly a classic east coast locality with no rivals for this rare species except those from Wisconsin.  Specimens from this locale are one of the true cornerstones of any respectable east coast site.  This twinned TN specimen measures 2.2 x 2.2 x 1.2 cm overall.  It is crystallized on front, sides and a small portion of the back.  This piece has two small chips but is still an exceedingly rare example, especially given the presence of the calcite crystals.  Not only are the calcites in good shape they are very attractive, lustrous, transparent to translucent and add nice aesthetics to a species which seldom has much in the way of  this characteristic.  The chalcocite’s luster is a higher than is the norm for these specimens, again adding to its aesthetics.  Sharply crystallized in all areas. Excellent provenance.  These things have become as rare as “hens teeth” and are of mineralogical important (ref. Rocks and Minerals, 11: 37 and the Mineralogical Record, 32, 433).  An exceptionally fine, rare and desirable specimen for the discriminating thumbnail collector.  1,600$

OKI-409

OKI-409     Apophyllite on Prehnite    Southbury, Connecticut.  Ex. Anthony Dunn Collection.  An aesthetic specimen with waves of rich green prehnite much of which is coated by crystals of clear and white apophyllite.  It measures 5.4 x 4 x 3 cm and is a damage free floater.  Very attractive piece.  75$

Dr. Steve Chamberlain Collection.  11.5 x 7.5 x 4.5 cm piece which is entirely coated by pea green prehnite and tiny calcites.  The perhnite is in casts over anhydrite and possibly datolite.  The prehnite cast is only a partial otherwise everything is complete and damage free.  A fine specimen for this price.  50$

OKF-382

OKF-382    Anhydrite Cavity in Quartz, Barite and Malachite    Cheshire Traprock Quarry, Cheshire, Connecticut.  Ex Dr. Steve Chamberlain collection.  Previously in the Herb Obodda and John Albanese Collections.  Four specimen tags are included with this piece documenting its fine province.  The specimen measures 9.9 x 8.2 x 5 cm overall.  The vug is composed of low luster crystals and casts totally lining the geode like opening.  The backside of the specimen has been sawn flat.  I see no damage to any the crystals or casts composing the specimen.  And very nice New Jersey piece with a great history.  $175

 

 

 

 

 

OKF-099

OKF-099    Wolframite pseudo after Scheelite    Trumbull, Fairfield County, Connecticut.  Ex.  Dr. Steve Chamberlain collection.  Previously in Union College collection.  Very unusual pseudomorph from an East Coast location that I am unfamiliar with.  The matrix is yellow quartz and the crystal measures 1.7 cm.  The specimen is 3.4 x 2.8 x 2 cm.  Very clean crystal considering the specimen was broken free from his quartz matrix.  $130

 

 

 

 

 

OKF-062

OKF-062     Babingtonite and Quartz    Hampden Quarry, Westfield, Hampden Co., MA.  Ex. Dr. Steven Chamberlain collection.  Prev. Ward’s Minerals.  Beautiful babingtonite crystals sit on clear to milky quartz crystals in this fine specimen. The babingtonites are an east coast classic and up to 1.6 cm in length in parallel growth.  The primary crystals sit up high on the quartz crystal matrix and display well.  The babingtonite is of the highest luster, nicely formed and aesthetic.  Some of the quartz is damaged but this does not distract from the quality of the important mineral here.  The entire specimen measures 3.4 x 2.5 x 2 cm.  140$
