New Materials From Tucson 2014 and Elsewhere...




OKL-557   Sphalerite, Galena, Calcite, Pyrite    Madan Ore Field, Rhodope Mountains, Smolyan Oblast, Bulgaria. A domical specimen measuring 5.5 x 5.2 x 3 cm with crystals to over a cm each.  An attractive mix of species exhibiting nice contrast, arrangement and diversity of textures.  Only edge contacts… excellent quality.   $35








OKL-558   Sphalerite, Galena, Quartz, Pyrite    Madan Ore Field, Rhodope Mountains, Smolyan Oblast, Bulgaria.  An outstanding mix of minerals with superb form and an aesthetic arrangement.  The galena shows spinel law twinning and the accessories are nicely distributed.  The yellow sphalerite in great but mostly on what I would call the back of the specimen (as easily could be the front).  All side nice and is damage free.  Sits up good for display and look fantastic from any side.  5.5 x 3.8 x 3.4 cm.  Very high quality.  $85







OKL-559   Spinel Law Twinned Galena    Madan Ore Field, Rhodope Mountains, Smolyan Oblast, Bulgaria.  Another fine piece with attractive twins sitting up high and on edge amongst a garden of quartz crystals.  6.4 x 4.5 x 3.8 cm.  The twins are very aesthetic, complex and of nice luster.  Not all lumped together like is often the case with this material.  The crystal separation is certainly a bonus for anyone wanting a good look at this unusual morphology.  No damage.  $50







OKL-560   Sphalerite and Galena    Madan Ore Field, Rhodope Mountains, Smolyan Oblast, Bulgaria. Attractive large cubes of morphed galena with circular growth hillocks dominate.  The reach 2 cm on edge on this 7.5 x 5.5 x 4 cm piece.  On these are wonderfully formed tetrahedrons with minor modifications, some of which sit up high off the galena.  Great piece with no damage.    $55








OKL-561   Sphalerite, Quartz and Galena    Madan Ore Field, Rhodope Mountains, Smolyan Oblast, Bulgaria.  A beautiful plate of yellow, gemmy sphalerites to 1.2 cm each on white quartz and minor galena matrix.  It measures 6 x 5 x 1.8 cm overall and is a damage free floater.  Great luster and overall aesthetics.  I think with most dealers this would command a much higher price but I think it will find a home fast at… $75







OKL-562   Sphalerite    Madan Ore Field, Rhodope Mountains, Smolyan Oblast, Bulgaria.  For a sphalerite from this prolific location this one is certainly exceptional.  It measures 8.2 x 5.5 x 3 cm overall with two distinct generations of translucent sphalerite.  There is one pin head sized micro ding that is not easily noticed so it isn’t “perfect”, but it is as close as it could be.  Fine luster and the aesthetics are impressive.  Displays great from any view.   $150








OKL-563    Quartz and Fluorite     Huanggang Mine, Inner Mongolia, China.  An attractive and interesting grouping of crystals dominated by the scepter quartz (to almost 6 cm each) and the transparent cuboctahedral fluorites (to almost 2 cm each).  The network of minerals shows no damage and only a very minor matrix contact, being almost a floater.  The scepters are singles and dumbbells, double terminated, and have interesting tan colored selective edge phantoms.  Minor sulfide accessories.  Complex and aesthetic!  9.5 x 7 x 3.3 cm.  Fantastic views from any direction.   $420








OKL-564    Vanadinite    Upper Moulouya District, Meknes- Tafilalet Region, Mibaden, Kkenifra Prov., Morocco.  An aesthetic 4.2 x 3.5 x 1.8 cm cluster of bright white barite blades setup an attractive contrast for the rich red, translucent vanadinite crystals.  This is a floater with only two tiny chips noticeable only with magnification.  Minor brown staining on back only.  Common material of uncommon quality.  $35







OKL-588    Scepter Quartz and Fluorite     Huanggang Mine, Inner Mongolia, China. An attractive miniature measuring 5.5 x 3.5 x 3.2 cm with well formed cuboctahedrons of transparent fluorite.  The largest crystal measures 3.4 cm in diameter and sits well in the center of the specimen.  Some faces are glassy and some show surface modifications but the transparency is very obvious.  The matrix is clearly seen through the crystals as are the small scepter quartz inclusions (very neat!). One small quartz scepter all on what appears to be dolomite.  Floater with only one old, healed contact.  A pretty amazing find for this quality and price.  $145







OKL-589    Barite on Copper with Malachite     RESERVED    Shangulowe Mine, Kambove District, Katanga Copper Cresent, Katanga (Shaba), Dem. Republic of the Congo. Not a huge specimen but very aesthetic and unusual.  It measures 5 x 2.5 x 2.2 cm and is dominated by a couple medium blue barites that diverge as the ascend.  The piece is a floater with large areas once attached to copper, and much remains, along its basal areas.  Great crystal development, transparency and luster all make this a desirable specimen.  This specimen is better in-hand.  Also, I have not seen much in the way of good specimens from the location.    $195







OKL-591      Dioptase on Calcite     Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.  This is a fantastic display with bright, transparent, lustrous green crystals on contrasting white calcite.  It measures 6.7 x 4 x 4 cm and is fully crystallized on its upper surfaces which are very three dimensional.  Some minor side coverage along a small vein too.  No damage and minor smithsonite overgrowths.  Mounted in a perky box.  $350








OKL-594    Datolite     Charcas, San Luis Potosi, Mexico.   6.7 x 4.5 x 2.5 cm domical specimen with a hollow back (base) that is also partially crystallized.  Attractive green, transparent/ translucent crystals to approximately a cm each.  No damage and nice looking.   $40








OKL-592    Chalcopyrite on Datolite     Charcas, San Luis Potosi, Mexico.  Big crystals to over 2 cm each compose this light green, with casts of yellow specimen.  7.3 x 6 x 2.7 cm slightly domical specimen with a single metallic chalcopyrite.  Attractive green, transparent/ translucent crystals.  No damage and fantastic in-hand.   $50








OKL-593    Datolite with Calcite and Chalcopyrite    Charcas, San Luis Potosi, Mexico.  Crystals to over a cm each compose this light green, with casts of yellow specimen.  Large chalcopyrites show some damage but otherwise clean..  White areas are overgrowths by calcite crystals.  7 x 6 x 2.8 cm slightly domical specimen.  Attractive green, transparent/ translucent crystals and nice color contrasts.  $50







OKL-595    Quartz on Datolite     Charcas, San Luis Potosi, Mexico.  Huge crystals to over 4 cm make up the piece each compose this light green, with casts of yellow specimen.  6.7 x 4.7 x 3.5 cm domical specimen.  Attractive green, transparent/ translucent crystals.  Light druses of clear quartz in select areas adds some “pop”.  No damage and excellent in-hand.    $50








Truest for color.

OKL-596    Quartz on Quartz and Calcite     Charcas, San Luis Potosi, Mexico.  An attractive, high luster grouping of primary quartz crystals with coatings of druse quartz (all clear) and clear calcites.  Lacking in color but still visually interesting.  9.2 x 5 x 4.5 cm overall.  Damage free.   $30







OKL-555    Quartz      Powers Farm, Pierrepont, St. Lawrence County, New York.  Ex. Michael Walter Collection.  Prev. Steve Nightingale collection. A fine example of the material recovered in the early 1970’s not seen for sale in modern times.  It came from a single quartz vein at the classic locality which has been fully worked to exhaustion.  7 x 4.5 x 3.5 cm overall with alpine quality smoky quartz crystals throughout.  No damage and good aesthetics.    $35









OKL-597    Calcite on Fluorite    Xianhualing, Hunan Prov., China.  This piece is dominated by two octaheda of transparent, green fluorite to 4.3 cm on edge.  On their surfaces are a few disc shaped rhombs of gray calcite for contrast.  The fluorite surfaces are etched looking however they are small modifications by cubes.  This has become contemporary material that will likely become classic.  The piece is a floater with healed contacts and in its base what appears to be a case that is also crystallized where the thin crystal (maybe anhydrite) was.  6 x 5.5 x 4.5 cm and no damage.  Harder and harder to find these now.  A great price on this one.  $40






OKL-598     Adamite and Calcite     Ojuela Mine, Mapimi, Durango, Mexico.   6.7 x 4 x 3.2 cm.  Attractive high luster example that sits on edge and displays beautifully.  The specimen is higher in luster than it appears in the images.   $35







OKL-599     Manganadamite and Calcite     Ojuela Mine, Mapimi, Durango, Mexico.  These specimens have always been uncommon and expensive!  This one however, is a value.  The interior crystals are well formed, chisel shaped crystals that are damage free and the typical white grading to purple color.  5.8 x 4 x 4 cm.    $150







OKL-600      Beryl, Fluorite, Quartz, Muscovite     Erongo Mountains, Namibia.  An unusual color for beryl found her in a domical specimen with many fine single and double terminated, hexagonal, transparent to translucent crystals to 1.1 cm.  A few green fluorites add some contrast.  The backside is also crystalized by smaller micas, black tourmalines and quartz.  A fine buy at… $55








OKL-601     Pyromorphite     Gongheng Co., Guangxi Zuang, China.  A modern day classic and what I believe will soon be recognized as the finest for the species, these pyros are becoming scarce and expensive in good quality examples like this one.  It isn’t huge measuring in at 3.9 x 3.4 x 2.4 cm but the quality is excellent.  The apple green crystals are the desired translucent variety and measure to approximately.5 cm each.  There is breakage to a couple crystals on the very edge of the specimen as might be expected, otherwise the piece is a damage free floater.  The matrix is crystallized and barren dolomite with what appear to be dolomite cases or possibly siderite.  Very aesthetic.   $250







OKL-602    Grossular on Vesuvianite     Sierra de Cruces, Coahuila, Mexico.  This big stocky double terminated vessuvianite crystals has areas coated by groups of grossular.  They are gray in color with clear surface.  The overall luster and form are good and the piece on has a base/ back contact and on very small contact area on the front.  Everything is in good condition.  5.7 x 3.3 x 2.5 cm.     $25







OKL-603    Galena, Sphalerite, Quartz     Commodore Mine, Creede Mineral Co., Colorado.  This specimen shows sphalerite in twinned crystals on quartz.  The piece is attractive with a moderate luster and interesting crystal congregation along one side.  The sphalerite ranges from the typical steel gray color and opaque to a yellow color and translucent.  8 x 5.5 x 3.2 cm.  Edge contacts but no damage.   $75







OKL-604    Fluorite and Galena    RESERVED     Naica, Chihuahua, Mexico.  A nice combination piece with well-formed crystals, the fluorite in the typical “Aztec pyramid” form and good luster. 6.1 x 5 x 3 cm.  No damage.    $35







OKL-605     Pyrite    Elba Island, Italy.  This is a nice sized example for the location dominated by one crystal 5.6 cm across.  The entire piece measures 5.6 x 4.6 x 3.7 cm.  The form is excellent and the luster high.  Minor stringers of galena on some surfaces and between crystals.  Base and edge contact isolated to one side.  All other views are excellent with no damage.  The piece sits and displays well.   $90







OKL-606    Fluorite and Quartz    Dong Po, Hunan Prov., China.  An attractive, inexpensive specimen measuring 8 x 5 x 3.3 cm with fluorites in cuboctohedral form to 2.6 cm each.  Some surfaces have fluorite overgrowths as can be seen,  Matrix is coated by druse quartz.  No damage.   $35








OKL-607    Barite on Quartz    Taxco, Guerrero, Mexico.  Large high luster white quartz crystals have a heavy coating of very clear barites all over them.  The back is matrix covered by the same clear barites.  No damage, only two edges with contact so it views great from multiple directions.  A sizable specimen at 12 x 8.5 x 4.5 cm. Nice! $60







OKL-608     Manganocalcite and Fluorite    Naica, Chihuahua, Mexico.  This is a really interesting specimen.  It is composed of a large, very light pink, partial calcite rhomb with overgrowths of fluorite cubes modified by dodecahedrons.  They are not large, up to about .7 cm each, clear, and very high in luster.  They sometimes show internal inclusions of mixed sulfides.  Very aesthetic.  On this are white calcites, also of nice form and decent luster.  7 x 5.5 x 4 cm overall with no damage.  Great views from every side. I think this is an excellent mix well worth the price.   $60







OKL-609    Sphalerite, Calcite, Pyrite     Naica, Chihuahua, Mexico.  Large sphalerites to well over 2 cm each on calcite with pyrite.  6 x 4.2 x 3.2 cm.  Contacts on small regions of back, bottom and one side.  Sits nicely and views well form most direction.    $35








OKL-610    Vanadinite in Barite    Upper Moulouya District, Meknes- Tafilalet Region, Mibaden, Kkenifra Prov., Morocco.  Amazing example with bright red/ orange crystals on snow white barite.  The contrast is out of this world, luster the highest you can find for this material, and the condition is spotless, having zero damage.  Sure to please the perfectionist.  6 x 3.8 x 3.7 cm.  Great views every direction.  Truly exceptional.  $195







OKL-611    Vanadinite in Barite    Upper Moulouya District, Meknes- Tafilalet Region, Mibaden, Kkenifra Prov., Morocco.  A bloom of white barite almost entirely coated by red vanadinites.  Very high quality with only on pin head sized crystal missing…impossible to see without magnification.  Great example measuring 4.4 x 2.8 x 2.5 cm.   $30






OKK-75    Apophyllite on Zeolites   RESERVED   Roncari Quarry (Tilcon Quarry), East Granby, Hartford Co., Connecticut.  5 x 3.5 x 3.3 cm with crystals to 1.5 cm on edge.  The other minerals appear to be anhydrite, pyrite and balls of what may be gyrolite.  I did not want to sacrifice this nice specimen for analysis.  It is the only one I am aware of with this unusual mineral assemblage and further, it is a fine, damage free, displayable example which I think has the best apophyllite crystals I have seen from the quarry.   $290
