OKN-189

OKN-189      Fluorite on Quartz and Garnet     Huanggang Mine, Hexigten Banner, Ulanhan League, Chifeng Prefecture, Inner Mongolia Autonomous Region, China.  Water clear fluorites on clear to milky quartz and below that a base of garnet.  The specimen measures 9.6 x 7.9 x 5 cm overall with fluorites to 4.6 cm across.  The fluorites dominated by the octahedral form with cubes and dodecahedral modifications.  All surfaces are lustrous and clear showing the matrix below and any inclusions.  The inclusions include enhydros and enhydros with bubbles.  Edge contacts but well formed complete crystals on the edges, as well.  No damage.  Another fine example of what has become important contemporary material from Mongolia.  $400

 

 

 

 

 

 

OKN-191    Fluorite on Quartz     Huanggang Mine, Hexigten Banner, Ulanhan League, Chifeng Prefecture, Inner Mongolia Autonomous Region, China.  To date, I have not purchased any of this material to resell.  I have found it to too expensive and seldom aesthetic.  This piece however caught my eye for several reasons.  It includes the normal ball shaped crystals with their deep blue color and rounded faces but the kicker is the large central crystal that it totally different from all of the others I have seen from the location.  This crystal is obviously a large cube.  It also shows accelerated growth along face contacts.  The nicest thing about the piece is that the crystals are well separated and not totally intergrown.  This allows you to really see them clearly and observe how truly strange their crystallography is.  They are on white quartz so the contrast is striking.  The crystals are a deep blue which does not come through well in photos.  They are translucent and have a medium luster.  This piece also has a total lack of damage that is rather rare for this material.  The specimen measures 16 x 15.2 x 6 cm in its longest dimensions and the largest crystal is 3 cm on edge or 4.2 cm in its longest dimension across.  If you have been considering one of these for your collection I would not wait long on this one.  The quality and price make me feel it will find a home quickly.  $700

 

 

 

 

 

 

OKN-192

OKN-192     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 example of which this one is the largest of the green color.  It is a plate of glassy green crystals that are totally transparent.  They are octahedrons to 2.9 cm on edge each with their surfaces completely covered by cubic modifications.  On the octahedron's terminations are sometimes seen large, more complex crystals.  The calcites are small and clear  and the quartz coating the dolomite matrix is also clear.  Striation sawed backside.  No damage. 12.8 x 8.5 x 3 cm.  Great piece of new fluorite.  $340

 

 

 

 

 

 

OKN-193

OKN-193      Calcite, Apophyllite and Stilbite on Quartz      Jalgaon, India.  A large showy partial vug of crystals dominated by a central calcite twin measuring 4.8 cm across.  The piece measures 16.5 x 14.5 x 7.5 cm.  The calcite sits on the matrix and a blocky apophyllite crystal and is flanked by a pink, double terminated stilbite measuring over 3 cm.  The calcite is gemmy with hardly any internal fracturing.  It has a pleasant light yellow color and the twinning can't be missed.  No damage.  Great display piece!  $825

OKN-195      Fluorite and Calcite      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.  The crystals are different however: 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 example of which this one is the only one of this color.  It is a plate of glassy green crystals that are totally transparent but they have been overgrown but clear fluorite and finally grape purple fluorite.  They are octahedrons to 3.6 cm on edge each with their surfaces completely covered by cubic modifications.  On the octahedron's terminations are often seen large, more complex crystals.  The calcites are small and transparent/ yellow or clear.  Only damage is one tiny tip crystal missing which is only discernable with magnification.  12.2 x 10.3 x 4.3 cm.  Great piece of new fluorite.  $470

 

 

 

 

 

 

OKN-194

OKN-194     Calcite and Heulandite on Quartz      Jalgaon, India.  A large showy partial vug of crystals dominated by a pair of intergrown, centrally located calcite twins measuring over 12 cm across in total!  The piece measures 16.5 x 14 x 11 cm.  The calcite is gemmy with some internal fracturing.  It has a pleasant light yellow color and the twinning can't be missed.  The quartz is extremely bright white making for a nice contrast.  No damage.  Beautifully trimmed, highly aesthetic display piece!  $900

 

 

 

 

 

 

OKN-196

OKN-196      Sphalerite with Chalcopyrite, Pyrite and Quartz      Yinfengjian Mine, Dongxiang County, Fuzhou Prefecture, Jiagxi Province, China.  This is a twinned sphalerite crystal that sits on a plate of quartz crystals.  The crystal weighs several pounds and has dozens of chalcopyrites in high relief dotting its surfaces.  These chalcos are in epitactic alignment with the sphalerite's crystallography!  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!  Everything has a high to very high luster.  What an unusual and aesthetic assemblage (although the piece is far more aesthetic and interesting in hand).  Backside has a couple crystals missing but sides, top, and front are in great condition and display better than the images indicate.  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.  This was the finest, by far.  This specimen will include a custom engraved acrylic base.   $1,500

 

 

 

 

 

OKN-200

OKN-200       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, I believe, is one of the two finest of the discovery.  It measures 7.4 x 5.4 x 4.7 cm overall. Individual crystals are to over 5 cm and they grad from the deep forest green color to clear at their tips.  A tiny, shallow contact from another crystal exists on one of the clear areas, otherwise a damage free floater.  The contact is facing you in the top right region of the last photo and is still difficult to make out.  A great heulandite specimen in all regards.  $400
