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.   





OKL-156    Adamite    Mapimi, Mexico.  A fine damage free example of the far less common color… 2.2 x 1.4 x 1 cm and mounted in a perky box.  Crystals are well terminated and attractive.  $30








OKL-837    Stibnite with Calcite    San Martino Mine, Mexico.  An aesthetic spray of crystals that are brighter and more lustrous in hand.  3 x 2.3 x 1.8 cm.  No damage.  An excellent thumbnail specimen and price.    $50








OKL-930    Adamite    Ojuela Mine, Mapimi, Durango, Mexico. A large matrix specimen measuring 9.1 x 7 x 2 cm with crystals to 1.2 in fan shaped groupings.  Entire surface has damage free crystals with really nice crystal separation and contrast.  Very high luster is not very evident in the image.  A fine showy example in a displayable piece.  A nice value at      $70








OKJ-893    Rhodochrosite    Chihuahua, Mexico.  A small pink .7 cm crystal in a void with surrounding crystals.  Main crystal is damage free as well as others but some are damaged if near edge of matrix.  2.3 x 1.5 x 1.5 cm.  Mounted in a perky box.  Great value at $30








OKH-444     Calcite    Sinaloa, Mexico.  A large crystal dominating a thin crystallized calcite matrix.  2.8 x 2.5 x 1.3 cm overall.  Good luster, excellent transparency to translucence and a honey amber color.  No damage anywhere.  A fine displayable example.  $65









OKL-754      Fluorite       Muzquiz, Coahuila, Mexico. An aesthetic, cluster of cubes modified by dodecahedrons. Nice light grape color, good transparency nd interesting surface features. Selective area phantoms (light white color) and any contact now healed. Excellent views from all directions. One crystal missing otherwise damage free. White bladed calcites. Nice. $70








OKL-214     Wulfenite    Los Lomentos, Mexico.  Ex. Thomas Fowler collection.  Great crystals of the high luster and form expected with the best of these.  Several crystals show damage however, so this one will be priced accordingly.  Crystals are very translucent and up to 1 cm on edge.  5.5 x 5.1 x 4.3 cm.  Mounted in a perky box.   $80







OKL-522     Adamite    Mapimi, Durango, Mexico.  A lustrous, damage free, transparent single crystal stands up off of the crystal and massive matrix to 2.6 cm high.  Overall, 2.6 x 2 x 1.7 cm.  No damage and mounted in a perky box.  $35







OKL-676    Mimetite      San Pedro Corralitos, Chihuahua, Mexico.  Ex. Thomas G. Fowler collection.   This appears to be the desirable material from the Benny Finn find in a small cabinet sized piece measuring 7.2 x 6.3 x 2.4 cm.  The color is mixed yellows and the luster average. One tiny touch mark can be seen in the central area of the specimen otherwise it is in good condition.  A modern classic.  $450







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-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-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-585   Danburite and Calcite     Characas, San Lois Potosi, Mexico.  Ex. Bob Trimingham collection.  This is a fantastic spray of damage free crystals (only breakage is on base (of course) up to 5 cm each with overgrowths of well formed, double terminated calcites.  Displays very well from all directions.  I don’t buy these often due to their often having damage and seldom having good aesthetics.  This one id spectacular!  7.5 x 7 x 6.6 cm.  Very light pink cast to the danburites but mostly water clear.  Very high quality and very reasonable price.  $190
