Mineral Specimens For Sale From the Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa

The fine smithsonites of Tsumeb are well known the world over.  The great variety of colors, crystal forms, and associated minerals make these specimens noteworthy.  Throw in the crystals in well formed and large crystals and one has what makes for world class specimens.  Fine examples are uncommon where as smaller, less colorful ones are still commonly available.  Pink, green, tan, blue, clear, black, orange, yellow... is there any color that doesn't exist?

 

 

 

OKL-650

OKL-650      Smithsonite    Tsumeb Mine, (more likely Berg Aukus) Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection. A large, crude, translucent mass of botryoidal material.  Rare color and uncommon form measuring 6.7 x 5 x 4.7 cm.  Very rough from breakage along one side and base.   $320

 

 

 

 

 

OKL-651

OKL-651      Smithsonite    Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.  Attractive light pink smithsonite crystals on a matrix that measures 5.2 x 3.5 x 2.8 cm overall.  The crystals are up to .9 cm each and have a lower luster due to a light frosting and an accessory mineral (unknown white coating) that is evident in the images. No damage.   $150

 

 

 

 

 

OKL-652

OKL-652      Cuprian Smithsonite    Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.  Crystals of this rare green variety are so uncommon, and fine examples like this, simply a rare thing on today’s market.  This high luster example is composed of stacks of transparent light green crystals to .6 cm each.  Their surfaces show an unusual rhombic patterning on their surfaces that I have not seen in this material.  All surfaces except the base and the lower part of one side are fully crystallized and aesthetic.  This is a very attractive miniature that measures 4.5 x 4.5 x 2.5 cm.  It stands on edge and views great from any direction.  I think it is damage free but when looped there is one area on side/ back that could show crystal contact.  It is really hard to tell.  I think this is about as fine a miniature as you could find of this rare stuff.  $1,200

Fowler collection.  Very sharply formed rhombs of an unusual brown colored smithsonite coat all of one side of this specimen and some small regions of its backside.  Close inspection will show tiny botryoidal groups of a green mineral that appears to be malachite in many areas of the display face.   The crystals are to .7 cm each and the specimen measures 6.3 x 4.8 x 2.1 cm.  The plate is basically a floater with only the smallest of contacts on back.  No damage at all.  Very fine piece.  $700

 

 

 

 

 

OKL-646

OKL-646      Cobaltoan Smithsonite    Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.  A very fine, large specimen measuring 9.2 x 6.7 x 4 cm overall with large crystals to 1.6 cm each.  The luster is fantastic and the contrast with the black matrix really sets off the color in these crystals which are an attractive pink/ purple color.  They are transparent to translucent and often have color variations within each crystal.  The white regions appear to be low lying cerussite some of which shows chipping.  This is minor as the entire piece is otherwise pristine.  Even the edges are very nice in quality not showing the typical breakage from matrix.  The piece displays best on edge but will not sit this way without aid.  A spectacular example of what some of the fines of these classic smithsonite crystal groups looks like.  I feel this price is a great one and anyone looking for a killer Tsumeb smithsonite should consider its acquisition.    $1,750

 

 

 

 

 

OKL-647

Cuprite in base

OKL-647      Smithsonite on what appears to be Cuprite casts after ?   Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection. The label simply stated “Smithsonite, Tsumeb, S. Africa”.  If someone told me that this was Berg Aukas, Grootfontein Dist., Namibia I’d be hard pressed to argue differently… except that cuprite is unknown from there.  This specimen appears to clearly have bright red cuprite below the smithsonite crystals and they even appear to be casts after some prismatic, bladed species that is now long gone.  A strange specimen for sure.  I’m left trusting the label and describing it as follows:  the crystals a a light yellow color with an interesting stepped surface growth, giving them an etched appearance.  They are quite large, to 1.6 cm each, and they coat these bright red casts of what appears to be cuprite.  A tiny cleave off one crystal on the end is all I can make out for damage so the specimen is in excellent condition, overall.  Some minor Styrofoam is attached to the base.  It displays nicely from any direction.  7.9 x 6 x 4 cm overall.  An attractive and unusual find from this prolific mine.  $650

OKL-349

OKL-349    Smithsonite      Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.  I think there were only two specimens like this in the collection, the other being less important and smaller, having smithsonites crystals with such pronounced phantoms.  Two generations of smithsonite are seen with the first being prismatic crystals of a pink to white color, transparent and small.  The second are larger, to .7 cm with bright yellow/tan colored phantoms.  The piece measures 7.1 x 5.2 x 3.2 cm overall.  It is visually aesthetic and stands on edge.  There is no damage and only minor matrix contact along one edge.  It views from any direction and is different from all directions.  The back is composed of several flat plates with crystals fully formed and less densely dispersed throughout.  Attractive and unusual for the species.  $2,500

 

 

 

 

 

 

OKL-350

OKL-350      Cadmian Smithsonite      Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.  Although it only measures in at 7.8 x 5.8 x 4.5 cm this is an important specimen for the collection.  The crystal size is massive with the largest crystal measuring a whooping 3.9 cm in length, yes, over an inch and a half!  The base is a contact area and the specimen sits nicely on this.  It is in fine shape all around with even the edges being very clean (composed of complete crystals).  Only one area along the edges shows the typical breakage associated with separation from it host rock.  The crystals themselves are a honey tan color on the interiors and a light tan to clear on their exterior surfaces.  The central areas on numerous faces are cavernous with smaller crystal terminations protruding from them.  The biggest crystal surfaces show minor dissolution along the edges of these protruding terminations.  It has somewhat of a dirty look until one figures out the tan colors are a view into the honey colored interiors of each crystal.  The luster is excellent but broken up due to the cavernous effect created by the dissolution etching.  This is one impressive piece for the species.  Displayable and hardy.  Viewers will think it has to be a calcite, couldn’t possibly be a smithsonite!  $6,000

 

 

 

 

 

OKL-343

This view shows scrape near base.

OKL-343      Cadmian Smithsonite Stalactite     Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.  A beautiful miniature sized stalactite completely coated (less one tiny area on the backside) by tan colored smithsonites.  One scraped area in lower 1/5th of piece visible in the first pic.  All upper regions beautifully lustrous and damage free.  The yellow/ brown varieties of this mineral are rare and Tsumeb is the one world wide locality most noted for them.  $800

Large transparent crystals

OKL-345      Cuprian Smithsonite      Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.   A fine green smithsonite in what again appears to be three generations of growth.  First, a green druse of cuprian smithsonites representative of most all of this rare material… next larger cuprian crystals to .7 cm (very large for this color), and finally in a couple places on the large smithsonites there are druses of white smithsonites.  It is only the front of the piece that is mineralized.  The specimen measures 5.8 x 4 x 2. 5 cm.  No damage.  Rare stuff.  $2,800

 

 

 

 

 

 

 

OKL-347

None of these images show the true, light pink, coloration present in this specimen.

OKL-347       Smithsonite      Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.  This example is another unusual one being composed of prismatic single and double terminated crystals on a dark matrix.  The color is actually a very attractive light pink and their luster is exceptionally bright for smithsonites.  The photos do not due these features justice.  In places there is either a secondary growth of clear smithsonites crystals or small cerussites.  They are so tiny I can’t even tell under 10x magnification.  6.4 x 4 x 2.5 cm.  The coverage by crystals includes the full front, about half the back, the top, and all of one side.  Bare are the base, one side and some of the back.  No damage, sits great… flashy in-hand.  It had a poor photograph session here.  $1,700

 

 

 

 

 

 

OKL-338

OKL-338      Smithsonite       Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia, South West Africa.  Ex. Thomas G. Fowler collection.  It would appear that there are three generations of smithsonites here:  small prismatic crystal of a very light pink to clear color, next larger, to 1 cm each, sharp rhombs of a tan color and finally, in some places a tan colored to pink druse on the previous generations.  The dark colored matrix makes for a nice contrast.  I detect no damage and only base contact.  Fully crystallized on all surfaces other than the thin base contact.  $395
