We carry a diversity of Mexican mineral specimens both from purchased collections and from more modern finds.  On the following pages you will encounter crystals from many locations and in many species.  Most are quite aesthetic and normally very reasonable in price however, high quality, damage free specimens of unusual or highly aesthetic species from Mexico have always commanded top dollar.   

 

 

 

 

OKI-550    Wulfenite    Sierra de los Lamentos, Chihuahua, Mexico.  Ex. Dr. Steve Chamberlain Collection, prev. Dr. George Robinson.  This is my favorite specimen of this bunch of wulfenites.  A 1.2 cm gem crystal sits up high off the matrix and couldn’t possibly display any better than this.  There is a pin head sized mark (visible with magnification) which does not draw any attention.  Amazing impact for a TN specimen.  From one of the most important North American mineralogical discoveries ever, written about in numerous books and periodicals.  Overall size of the piece is 2.5 x 2.4 x 1.9 cm.  An important specimen in need of a place in a top TN collection.    495$

 

 

 

 

 

 

 

OKI-552    Wulfenite    Sierra de los Lamentos, Chihuahua, Mexico.  Ex. Dr. Steve Chamberlain Collection, prev.

Nice piece.  225$

 

 

 

 

 

 

OKI-605    Azurite on Quartz    Chihuahua, Mexico.  Ex. Nancy Collins Collection.  This 2.8 cm long quartz point is coated on several sides by well formed, deep blue azurites to several millimeters each.  One side is heavily coated, two sides only lightly coated and the final side is pretty much crystal free.  Nice vibrant color which is expected of all top azurite crystals and the highest of luster (low luster on the quartz provides for both a luster and of course a color contrast).  One small area missing crystals...looks better in person.  Very nice TN specimen.  75$

 

 

 

 

 

 

OK-007    Vanadinite    San Carlos, Chihuahua, Mexico.  Ex. Dr. Steve Chamberlain collection.  Prev.

OKF-657    Gypsum     Mapimi, Durango, Mexico.  Ex. Dr. Steve Chamberlain collection, prev. Ralph Lapham collection.  This is an old specimen which is very interesting due to what is inside.  Running most if the crystals length is an inclusion (negative crystal) which is approx 2 millimeters wide and 5.5 cm long.  The entire crystal measures 10 x 2 x .7 cm.  It is double terminated and striated along its narrowest faces.  Even the inclusion has striations!!!  Little marks here and there on the surface of the crystal (I’m not convinced that these are damage even with magnification).  A fine piece for…80$

 

 

 

 

 

 

OKI-141     Adamite      Ojuela Mine, Mapimi, Durango, Mexico.  Ex.

OKF-375    Wulfenite (dipyramidal crystals with pinacoidal terminations)    San Juan Poniente, Ojuela Mine, Mapimi, Mexico.  It's funny to hear other dealers talking over the past year about these unique looking wulfenite crystals.  They make it sound like they've never been found before whereas this one likely dates back to the early 1970s.  No matter its age it is an exceptional display piece which also has a mix of what appears to be clear to white calcites and a good deal of yellow and brown micro- mimetites?  The wulfenites are both single and double terminated and up to 1.6 cm in length.  I can only find a couple with the aid of magnification which show damage.  One small area contact on backside.  To the eye this piece is exceptionally clean and viewable from all sides although the photos do it no justice.  The price is well below what specimens of this size from the new find are running.  This one sits beautifully for display and measures 7.5 x 5.5 x 4.4 cm.  Excellent luster, form and aesthetics to these crystals.  $300

 

 

 

 

 

 

 

OKF-184      Datolite on Sphalerite    Charcas San Lois, Potasi, Mexico.  Ex. Nancy Collins collection.  This beauty is also an old-timer with translucent and transparent datolite crystals to over 2 cm each.  These crystals have a unique and complex form and a stand on edge well-off the matrix.  They are all damage free and attractive the entire piece measures 4.5 x 4 x 3.2 cm.  An interesting and showy specimen unlike those produced in more modern times.  $125

 

 

 

 

 

 

OKF-153    Dolomite and Calcite    Guanajuato, Mexico.  Ex. Nancy Collins Collection.  This is an unusual piece in which each quite colored calcite is bisected by a zone of clear calcite.  The effect is unusual and easy to notice in the photographs.  The specimen measures 9.2 x 6 x 4.7 cm.  Moderate luster to the point sections of crystals and high luster possessed by the clear areas.  $160

 

 

 

 

 

OKF-146    Fluorite on Quartz    Naica, Mexico.  Ex. Nancy Collins Collection.  A single light green fluorite octahedron stands up nicely on the large bed of quartz.  This dome shaped specimen displays great from all sides.  The piece is damage free and very displayable.  $180

 

 

 

 

 

 

OKF-139    Wulfenite    Los Lamentos, Chihuahua, Mexico.  Ex. Jim Turek Collection.  This large 7 x 7 x 5 cm Crystal grouping is composed of several layers of well formed, high luster wulfenite crystals.  They are somewhat barrel shaped, which is a typical for the location, and up to 1 cm in length.  Under magnification I can only find one small crystal missing on the front side.  One edge has some matrix contact, otherwise it is a floater.  Backside of grouping is more highly stained and has several dings or missing crystals.  The display face in this piece is wonderful and it sits well for display on several sides (edges).  A very desirable modern-day classic.  $400

 

 

 

 

OKF-131    Vanadinite on Wulfenite    Ahumada Mine, Los Lamentos, Chihuahua, Mexico.  Ex. W.P. Hinley Collection, Circ. 1930s.  This specimen is a fine miniature composed of blocky wulfenite crystals to 1.4 cm on edge.  The entire specimen measures 5.4 x 5 x 3.3 cm.  The front sideshows better luster and less coating from the brown vanadinite.  This front side is perfect in all regards.  The backside is more heavily coated and has a few crystals are chipped.  The stack of crystals is very aesthetically composed having several hollow areas between crystals.  These blocky butterscotch colored vanadinite crystals show two different colors forming distinct layers in every crystal.  The color ranges from butterscotch in one layer to a reddish-brown any underlying layer.  This is a highly desirable and aesthetic display piece.  $500

 

 

 

 

 

 

 

OKF-063     Adamite    Ouela, Mexico.    Ex. Dr. Steven Chamberlain collection.  This piece is a rather unusual form for the location.  The adamite is composed of microcrystals which take on a botryoidal form, almost stalactitic.  It has a nice apple green color over most of its surface with the backside having some staining giving those areas a brownish tint.  Specimen is glued into Perky box.  Damage free.  3.6 x 2.1 x 1.6 cm.  125$

OKA-598C     Danburite/ Calcite San Luis, Potois, Mexico. Yellow calcite crystals (small) form a sheath surrounding the base of each of these crystals of danburite. Terminations are all damage free and fully exposed above the calcites. Danburites are clear/ light pink in color. These are unusual and superb display pieces. I got a great deal on them and so have them at a lower price than is the norm. 100 to 200$ would be a more typical price. Sure to please.  This one is a stocky 7 x 5.5 cm crystal.   50$

OKA-678 Grossular Sierra de Creces, Mexico. I usually don¹t get these raspberry colored garnets due to the extensive damage to almost every specimen. Here are five that are exceptional...specimens are 5 to 7 cm each and have lots of garnets in each. Each grossular is .5 to 1.5 cm. Great color and form in all these. 50$ and 60$ each

 

 

 



OKA-744 Amethyst Geuraro, Mexico. After 6 years of looking for this material I final found a flat (wholesale!!). Amethyst phantom in clear quartz. All are large points with smaller attached sister crystals around the main crystal. Crystals usually taper toward tip. Most have enhydros, some with gas bubbles. This is extremely difficult to get in specimens more than a couple cm long. Pieces are usually only available from old collections. This is a classic site often discussed in the historic texts. Grab these up fast.
