Back

OKN-212     Fluorite    Dayu County, Ganzhou Prefecture, Jianhxi Province, China.  A nice grouping of light grape colored fluorites.  Sawn flat on base in order to sit on edge nicely.  Backside is frosted.  Back has several tiny cleaves but the specimen is great from top, sides and front.  Medium luster, nice curved form.  7.7 x 4 x 3.1 cm.  Cubes are up to 1 cm each and some have stepped corners or edges.  $120

 

 

 

 

 

OKN-211

OKN-211     Fluorite      Xianghualing Mine, Hunan Province, China.  Four generations!  8 x 7.1 x 4.5 cm.  Domical shape.  Frosted luster, one tiny ding on top green fluorite is tough to notice.  Nice and unusual specimen.  $200

 

 

 

 

 

 

OKN-210

OKN-210      Calcite on Dolomite    Shang Bao Mine, Lei Yang, Hunan Province, China.  Very lustrous (looks lower in luster in images), clear calcites on light pink dolomites.  11.3 x 7 x 5.8 cm piece with attractive calcites with several modifications.  I've never seen calcite quite like this one from the Shang Bao Mine before but this particular dealer has been very reliable on locations in the past.  No damage.  Very nice example!  $200

 

 

 

 

 

 

OKN-213

OKN-213     Sphalerite with Chalcopyrite, Pyrite and Quartz      Yinfengjian Mine, Dongxiang County, Fuzhou Prefecture, Jiagxi Province, China.  This is a twinned sphalerite crystal with lots of accessories.  The crystal has dozens of chalcopyrites in high relief dotting its surfaces.  These chalcos are mostly in epitactic alignment with the sphalerite's crystalography!  Next came the pyrite in a form that looks just like someone painted the material onto the surfaces of the chalcos and the sphalerite.  Next came more pyrite in well formed crystals randomly scattered about on everything!  one tiny cleave to the sphalerite will need to be searched for as it blends in making the piece look to be damage free.  This is a very impressive piece.  I only found three of these with all the Chinese dealers that I felt were in good enough condition to invest in.  $375

 

 

 

 

 

OKN-214

OKN-214       Heulandite-Ce with Celadonite inclusions       Nashik District, Maharashtra, India.  The heulandites seen here represent what I believe may be some of the finest found to date from anywhere.  Why?!  Well, it is not just their impressive size, rich color or fabulous luster.  The form seen here is uncommon and most of the pieces are floaters with no damage, what-so-ever.  To begin with these specimens were discovered in 2015 as a single pocket.  I checked all the Tucson dealers and no one else had any or was aware of anyone who did.  The dealer who did have these specimens knew they were of exceptional quality for the species and was very stubborn with his pricing.  It took two days and three visits to finally negotiate a deal on a dozen pieces I high-graded form his total lot of perhaps 35 specimens.  I certainly grabbed up what I deemed the finest of the lot.  I've occasionally seen large green specimens like these in the past but they have always been uncommon in this size and color.  The problem with past finds has been their lack of luster.  The crystals had flat, graining surfaces (similar to the poorest areas on these crystals) and seldom had the same deep forest green color.  These new examples have exceptional luster for the species, very large crystal size, a rare crystal shape, and in most cases no points of contact to matrix.  In hand they look like flowers with gentle curves that reflect the light as they are turned.  They are impressive and the best of them are simply the "best of the best" when it comes to heulandites. 

This one measures 8.6 x 6.6 x 5 cm overall. Individual crystals are to 4 cm and they grad from the deep forest green color to clear at their tips.  This is a damage free floater.  Wonderful wave like crystals.  A great heulandite specimen in all regards.  $250

Back with calcite discs

OKN-215     Fluorite and Calcite     Xianghualing Mine, Hunan Province, China.  Four generations!  82 x 5.2 x 4.2 cm.  Elongated shape.  Frosted luster, one tiny ding on gray fluorite is tough to notice.  Good calcites on back upper edge.  Nice and unusual specimen.  $175

Bottom or back

OKN-216     Fluorite, Calcite, Quartz      near Xinyang, Henan Province.  This location has been described to me as being near the Xinyang Mine but not from the mine itself.  It is similar to the material that surfaced in 2014 but far clearer and not as bright a green.  The crystals are different too: these are reminiscent of the Naica Mexico "Aztec Pyramids" once common on the mineral market.  In any case, they are beautiful so I purchased eight or ten examples.  On this one the crystals are glassy green crystals and totally transparent.  The octahedrons are intergrown and their surfaces completely covered by cubic modifications.  On the octahedron's terminations are seen large, more complex crystal terminations.  The calcites are small and clear  and the quartz is sparse and white.  The backside is somewhat crystallized and there is only a single small area of contact on one edge. 6 x 5.6 x 3.3 cm.  Great miniature sized piece of new fluorite.  $190
