OKP-422

OKP-422     Fluorite and Barite       Mina Jaimina, Caravia, Asturias, Spain.  Ex. Bob Borofsky.  This fine miniature measures 5.4 x 4x 3.5 cm.  A large, complex fluorite makes up the body of the specimen and on this are barite blades and smaller fluorite crystals mixed in with them.  The piece is a floater with no damage.  There are a couple healed barites and a healed area on the base of the fluorite.  Need some simple soap and water cleaning to improve its aesthetics.  The crystals of fluorite show well developed tetrahexahedral modifications on cubes.  Moderate luster.  A great Spanish piece in all regards.  $300

 

 

 

 

 

OKP-423     Pyrite and Calcite on Fluorite       Mina Jaimina, Caravia, Asturias, Spain.  Ex. Bob Borofsky.  This fine miniature measures 5.5 x 4.5 x 3.6 cm.  A large, complex fluorite makes up the body of the specimen and on this are pale calcites and smaller fluorite crystals mixed in with them.  The piece is a floater but does have a base contact and a couple of visible chips as seen.  It sits nicely on the contact area displaying very nicely.  The crystals of fluorite show very minor tetrahexahedral modifications on cubes.  The pyrite is bright and the luster n the fluorite is exceptional.  $320

OKP-424     Barite       Mina Jaimina, Caravia, Asturias, Spain.  Ex. Bob Borofsky.  This fine miniature measures 6 x 4.4 x 4.3 cm.  The cluster of bright barites is fully formed on all sides and back with only a small base contact on which it sits.  Exceptional condition with no damage, even on back.  Light blue color and good translucence tot he crystals.  $225

 

 

 

 

 

OKP-425

OKP-425     Fluorite and Barite       Mina Jaimina, Caravia, Asturias, Spain.  Ex. Bob Borofsky.  This fine cabinet specimen measures 9.5 x 7.7 x 4.4 cm with the largest crystal measuring 5.4 cm on edge.  A large, complex fluorite makes up the body of the specimen and on this are barite blades and smaller fluorite crystals mixed in with them.  The fluorite has white/clear cores and light blue (not purple as my camera has captured it) phantoms.  It is in excellent condition with only minor chipping on a couple of barites.  The fluorite shows a tiny internal crack (seen in the second image).  The crystals of fluorite show well developed tetrahexahedral modifications on cubes.  Moderate luster.  A great Spanish piece in all regards.  $375

 

 

 

 

 

OKP-426

OKP-426       Fluorite       Emilio Mine, Asturias, Spain.  Ex. Bob Borofsky.  This fine cabinet specimen measures 9 x 6.9 x 4 cm with the largest crystal measuring 1.1 cm on edge.  What makes this specimen special is the color.  Unlike other localities where purple is a common color it is the rare color at the Emilio Mine.  The crystals are in very good conditions as seen but one patch on lower part of piece has missing ones.  The crystals of fluorite show what appear to be well developed hexoctahedral modifications on cubes.  Moderate luster due to frosted surfaces.  Excellent transparency. Back of piece is also completely crystallized.  Not photographed but those crystals are white cubes modified by octahedrons.  They are duller and not the major interest in this specimen.  $250

 

 

 

 

 

OKP-427

OKP-427     Aragonite      Monlina de Aragon, Guadalajara, Spain.  Ex. Steve Chamberlain collection.  Circ. 1976.  This miniature measures 4.3.9 x 3.4 x 2.2 cm.  It is a complete floater with a couple healed areas having smaller attached crystals.  No damage, nice transparency, and a light purple color.  $25

 

 

 

 

 

OKP-428

OKP-428     Aerinite         RESERVED       Estopinan, Spain.  Ex. Steve Chamberlain collection.  Prev. Bill Dossert.  Circ. 1976.  Medium blue (bright for the locality) crust on matrix.  Type locality for species.   The specimen measures 2.8 x 2.6 x 2.5 cm.  $35

 

 

 

 

 

OKP-429

OKP-429      Fluorite and Barite         La Collada, Asturias, Spain.  Ex. Bob Borofsky.  This large fluorite specimen measures 12.7 x 8 x 8 cm and has crystals to 3.3 cm on edge.  The piece is flat on the base and also flat on the back with the back being crystallized by much smaller crystals than the display faces.  The crystals are clear with blue phantoms.  Some of the phantom boundaries are also lightly coated by pyrite crystals (as inclusions).  The barites are chisel shaped, clear and very sharply formed.  The only breakage to the barites in directly at the edge with the base.  The fluorites show a couple chips but are in excellent condition overall.  They are also showing minor modifications on edges.  Sits and displays beautifully.  $450

 

 

 

 

 

OKP-430

OKP-430      Quartz casts after Anhydrite with Quartz and ???      Roncari Quarry, Tilcon Quarry), East Granby, Hartford, Connecticut.  Collected by Jerry Marchand.  This specimen id from what Jerry nicknamed the "Halloween Pocket", for the crazy crystal colorations he encountered.  This is probably the best piece from the find.  It measures 18.5 x 10.2 x 9 cm and is basically a large vug that sits nicely on edge, as seen in the photos.  Inside can be seen calcites with odd coatings or pseudomorphing of a nice orange color.  On these are "stars" of what is likely goethite but not confirmed.  Also inside the vug are fine quartz casts after anhydrite to approximately 3 cm.  The back of the piece is totally coated by calcites similar, but smaller, than those in the vug on the front.  The contact is along the edges of the vug but not all of them.  Overall the condition is excellent .  An extremely interesting and unusual specimen in many ways.  $1,400

 

 

 

 

 

OKG-409

OKG-409      Calcite on Quartz casts after Anhydrite       Roncari Quarry, Tilcon Quarry), East Granby, Hartford, Connecticut.  Collected by Jerry Marchand.  This is a very large example of this material measuring 7 x 6 x 3 cm.  The larges calcite is 3.2 cm and has a tip cleave.  Other than this the specimen is in fine condition on all sides.  Most of these came out badly damaged so this is a very fine example.  $300

 

 

 

 

 

OKP-433

OKP-433      Calcite, Hematite, Quartz       Roncari Quarry, Tilcon Quarry), East Granby, Hartford, Connecticut.  Collected by Jerry Marchand.  This cabinet specimen measures 12.2 x 10 x 7.7 cm and has complex crystals of calcite to 4.4 cm each.  Interesting selective face phantoms are found within each crystal as well as selective face surface coatings of gray and brown hematite.  Hematite roses in these same colors are also present on the quartz crystal matrix.  No damage.  Calcite with phantoms are very rare at this occurrence.  $375

 

 

 

 

 

OKP-432

OKP-432      Calcite, Hematite, Quartz       Roncari Quarry, Tilcon Quarry), East Granby, Hartford, Connecticut.  Collected by Jerry Marchand.  This cabinet specimen measures 13.4 x 10 x 6.5 cm and has complex crystals of calcite to 3.8 cm each.  Interesting selective face phantoms are found within each crystal.  Even the tiny crystals show these interesting phantoms.  The phantom colors range from gray, to silver, to brown.  The surface features also often reflect parallel growth with the phantoms.  Very unusual for any calcite locality.  No damage.  Calcite with phantoms are very rare at this occurrence and this is among the few very finest ever found.  This would be an important specimen for the Roncari.    2,800

 

 

 

 

 

OKP-431

OKP-433      Celestine, Calcite, Quartz       Roncari Quarry, Tilcon Quarry), East Granby, Hartford, Connecticut.  Collected by Jerry Marchand.  This is a rare find from this quarry.  It is the only example of celestine I have seen among the many thousands of specimen observed from the site through the years.  It is also substantial measuring 8 x 6 x 4.6 cm.  The white quartz crystal is 3.7 cm and the main celestine cluster measures 3.5 cm long.  The piece is damage free and sawn flat on its base so it sits beautifully for display.  The celestine crystals are a medium blue (bluer than the images) and have hematite inclusions, as seen.  Another rare and important specimen for the quarry.  $950
