OKF-414

OKF-414        Quartz, Calcite, Hubeite and Apophyllite    Daye Mines, Hhuangshi, Hubei Prov., China.  This fine specimen is the 14^th piece I added to my private collection back in the mid-1990s when I collected Chinese minerals exclusively.  It was even before the identification of the species Hubeite!!  The specimen is 9.5 x 8 x 6.5 cm overall and is comprised of a wonderful mix of species.  The quartz is milky to clear and along with the calcite rhombs (to 1.7 cm on edge) make up the body of the specimen.  Sprinkled on these minerals are gem clear apophyllite tabs to 1.2 cm and brown hubeite balls to .9 cm each.  There is a frosted effect to the front of the specimen yet the back of the piece is missing this effect.  This piece is better that almost all I have seen.  Perfectly sized and very aesthetic.  Everything is terminated, damage free and interesting to look at.  Minor basal contact and viewable from all sides.  The specimen even sits well for display.  This piece has it all!  I do not believe you will find a more displayable specimen of this mix of minerals for sale anywhere.  350$

OKF-415       Axinite    Henan, Lushi Prov., China.  A fine plate of purple/ brown axinite crystals to 1.4 cm each with minor, white calcites sprinkled on top to add some contrast.  This high luster plate is actually a floater which has minor mineralization on its sides and back.  Overall measurements are 9 x 7.5 x 3.5 cm.  Zero damage and it even stands nicely on edge for display.  All the axinites are sharp in form and the piece is very aesthetic although the photos have a hard time reflecting this fact.  An excellent example of this uncommon material.  175$

OKE-416        Tourmaline    Yunnan, Wenshan Prov., China.  I was thrilled to acquire this unusual specimen!  Great tourmalines from China are as yet rather rare.  Especially ones of this high a quality.  This fine green specimen measures 6.1 cm long and is fully terminated on all areas of both ends.  The crystals are hoppered and translucent to transparent depending on what area of the crystals you are observing.  The color is a vibrant green.  Numerous tiny rider crystals are sprinkled on the back of the piece but it is dominated by two primary crystals.  I have this priced way too low by all comparable standards but I got a good deal on it so have at it.  Oh, did I mention that there is no damage what so ever and the specimen actually stands on end for display!  Wow.  450$

 

 

 

 

 

 

OKF-417

OKF-417        Manganocalcite on Arsenopyrite, Quartz, Cassiterite, Pyrite and Stannite    Yaogangxian Tunsten Mine, Yizhang County, Chenzhou City, Hunan Prov., China.  Here is another magnificent combination piece which we have grown accustom to seeing from the Yaogangxian Mine.  This one showcases poker chip stacks of calcite on the metallic minerals for a fine contrast in colors and forms.  The calcite is very light for manganocalcite so I’m not sure if I should believe the dealer on this one.  Even so it is a fine display specimen measuring in at 9.1 x 7.1 x 5 cm.  It stands on edge and has no damage.  It views well from all sides and is mineralized on every surface including its base.  An excellent specimen for the money.  170$

 

 

 

 

 

 

OKF-418

OKF-418        Calcite      Daye Mine, Huangshi, Hibei Prov., China.  I have lots of these two generation calcite specimens to offer but this is by far the most aesthetic.  It is comprised of several calcite schalenohedrons with tabular rhombs attaches on numerous surfaces.  The goethite inclusions make it a real looker from all side except its back.  8 x 7.5 x 5.5 cm.  No damage to any display faces except for a tiny ding on what might be the smallest of all the crystals.  Very showy.  270$

OKF-419        Azurite Ball    Yangchun Mine, Mao Ming, Guangdong Prov., China.   China has rarely been able to compete with fine American and South African azurite specimens… pieces like this are an exception.  This is the best of these specimens that I have owned over the many years that they have been available.  The ball measures 8 cm in diameter and has crystals to 1.8 cm (with most averaging better than a cm each).  It is of the highest luster and deepest blue color that can be found for the species anywhere.  All sides are equally well mineralized with the exception of one (which has smaller crystals).  This damage free ball is a stunning eye catcher in even the most aesthetic display case.  Holding this fine piece really brings home how substantial it is.  I have sold many higher priced azurites over the years, but I believe this may be the finest azurite I have ever owned.  Thankfully the Chinese specimens have not been in as high demand as domestic and African varieties.  A fine value at…1,500$

 

 

 

 

 

OKF-520

OKF-520        Calcite    Xianghauling Cassiterite Mine, Linwu County, Chenzhou City, Hunan Prov., China.  Here is the very first Chinese specimen I bought for my own collection.  I still love this piece (but I don’t collect Chinese minerals any longer) and believe it displays better that any similar calcite.  It has a silky, matt like finish on transparent crystals to over 8 cm each.  Overall the specimen measures 10 x 8.2 x 7.5 cm.  It views well from all sides and is damage free.  I’ll let the photos speak for themselves.  160$

 

 

 

 

 

 

OKF-521

OKF-521        Quartz    Blair Hill Farm, Greely, Ontario, Canada.  Ex. Dr. Steve Chamberlain Collection.  The specimens from this Canadian “Herk” occurrence rank among the best quartz specimens from anywhere in the world (yes, even better than Herkimer Co. New York!).  They are higher in luster and have a nicer smoky tint than almost any specimen of quartz.  The problem is that this occurrence has not produced many noteworthy specimens and extremely few which show no damage.  The specimens are highly skeletal and floaters although this one has two tiny matrix contacts to its base.  This one has one broken face but is otherwise clean.  It measures 5.7 x 4.4 x 3.6 cm and has a tiny carbon included stem sticking out of its base.  The price reflects the fact that there is visible damage.  90$

OKF-523        Quartz    Blair Hill Farm, Greely, Ontario, Canada.  Ex. Dr. Steve Chamberlain Collection.  The specimens from this Canadian “Herk” occurrence rank among the best quartz specimens from anywhere in the world (yes, even better than Herkimer Co. New York!).  They are higher in luster and have a nicer smoky tint an most any specimen of quartz.  The problem is that this occurrence has not produced many noteworthy specimens and extremely few which show no damage.  The specimens are highly skeletal and floaters although this one tiny matrix contacts to its base where the specimen number is glued on.  It measures 5.5 x 3.5 x 4 cm.  The surface growth features are very nice and it is difficult to decide how to display this specimen in that it views nicely from all directions.  300$

OKF-524        Copper in Calcite    Centennial Mine, Keweenaw Penninsula, Michigan.  Ex. Mary J. Perry Collection.  Circ. 1930.  This piece is composed of two schalenohedral crystals with clear secondary calcites coating their surfaces.  The copper just glows through on this specimen with very little actually reaching the surface.  In the couple of small spots where the copper has been exposed it has a dark copper patina with minor green oxidation.  Overall the specimen measures 7 x 6.5 x 5.8 cm and it displays beautifully on the only non-crystallized area of the piece.  This damage free piece displays nicely from all views and is a fine example of this now rare, classic American material.  750$

OKF-420

OKF-420      Titanite    Capelinha, Minas Gerais, Brazil.  Ex. Dr. Steve Chamberlain Collection.  Prev. Ward’s Minerals of Rochester, 1976.  This nice specimen barely fits in a perky box diagonally…4.8 x 2.3 x 1 cm twin.  Fully formed with only a minimal area of contact on its base and a couple of very tiny nicks.  Transparent to translucent with nice gemmy areas throughout with excellent luster on most surfaces.  Sharp reentrant angle and interesting surface growth features. An outstanding example of the species.  85$

 

 

 

 

 

OKF-422

OKF-422       Dolomite Twin    Eugui, Navarro, Spain.  Ex. Dr. Steve Chamberlain Collection.  Prev. Donald Briggs collection, 1978.  Here is one of what are certainly the best dolomite crystals from anywhere in the world.  It just fits into a perky box at 2.5 cm on edge.  This translucent twin has a couple minor spots of contact, otherwise a floater.  Great luster and form.  Light gray internal veil.  An outstanding example of this difficult to find material.  50$

 

 

 

 

 

 

OKF-423

OKF-423       Brazilianite    Conselheira, Pena, Minas Gerais, Brazil.  Ex. Dr. Steve Chamberlain Collection.  Circ. 1983.  A fine thumbnail specimen composed of two sharply terminated crystals measuring 3.3 x 2.2 x 1 cm overall.  High luster and mirror clean faces.  Crystal on left is gem and missing its tip, otherwise in fine condition.  Gem rough alone makes this piece a good buy but it is first and foremost a fine mineral specimen.  65$

 

 

 

 

 

OKF-425

OKF-425       Apophyllite    Cornwall Iron Mines, Cornwall Co., PA.  Ex. Dr. Steve Chamberlain Collection.  Circ. 1978.  3.5 cm football shaped cluster composed of radiating crystals to 1.7 cm on edge.  This is one of the best thumbnail specimen of these that I have seen..  This one only has a very tiny matrix contact under the collection number and has zero damage.  Another great east coast classic!  60$

 

 

 

 

 

 

OKF-426

OKF-426       Pyrite    French Creek Mine, St. Peter, Chester Co., PA.  Ex. Dr. Steve Chamberlain Collection.  Prev. Alvia E. Schortmann collection.  Here we go again with another fine example of an east coast classic of outstanding quality.  This pyrite cluster measures 3.9 x 3 x 3 cm and has to be perfectly positioned in order to fit in a perky box (but it does fit!).  Probably a floater but there is some Styrofoam attached to the base still.  Damage free with one thin strip of massive pyrite on backside.  Views great form all angles.  Beautiful curved faces with a silky luster.  Amazing thumbnail…probably the best I have seen of hundreds from this classic locality.  Very reasonably prices for such an outstanding example…170$
