OKN-654

OKN-654      Rhodochrosite      N’Chwaning Mine, Kalahari Manganese Fields, North Cape Province, South Africa.  Ex. Thomas Fowler collection.  Circ. 1970s.  Obviously not the bright transparent red rhodochrosite for which the mines are so famous.  The rhodo specimen is a heavy coating of crystals to several millimeters each.  They have excellent luster and are bright pink as seen here.  The first image, bottom right on edge, shows and open case which makes it likely that the larger domes on the piece are casts after an unidentified rhombohedral mineral.  There is no damage to the display surface and it measures 8.2 x 6.65 x 3.5 cm.  Slightly domical and somewhat triangular in shape.  Very nice example.  $450

OKL-404

OKL-404      Rhodochrosite on Manganite     N’Chwaning Mines, Kuruman, Kalahari Manganese Field, North Cape Province, South Africa.  Ex. Thomas G. Fowler collection, circ. 1970s.  A beautiful, damage free, showy example of this rare and coveted material.  It measures 5.2 x 2.5 x 2 cm and is well crystallized both front and back.  Fully formed crystals coat the front most richly with the top also having may of these bright pinkish red crystals.  The back has fewer and one side as well.  One side and the base are not coated with crystals.  Under all areas where rhodos appear can be found dark black and highly lustrous manganite crystals.  There are several groups of cream to clear colored crystals that appear to be Cerussite.  They are also highly lustrous like all the species mentioned already.  The piece has zero damage and stands on edge for display.  Very sharp!!  $3,000

Feb. issue of The Mineralogical Record (vol. 48, no. 1, p. 102-103).  No damage.  An unusual yet attractive pink color with minor brownish stains or mineral overgrowths.

OKH-493

OKH-493      Rhodochrosite      N’Chwaning Mines, Kuruman, Kalahari Manganese Field, North Cape Province, South Africa.  Ex. Thomas G. Fowler collection, circ. 1970s.  This closed manganese mine once owned by Assoc. Manganese Mines of South Africa, Ltd. has produced what many consider to be the finest rhodochrosite specimens ever found.  Due to their rarity they remain one of the most difficult collectable mineral specimens to find in quality pieces.  We have available a limited quantity of these rare rhodos due to the recent acquisition of the Thomas G. Fowler collection.  The ones listed here show limited or no damage (very rare for this material) and range from a very dark reddish pink to a rich, bright red.  All specimens have spectacular luster and intense color saturation, no matter what their color. 

This nice three dimensional grouping of crystals measures 3.8 x 3 x 1.4 cm.  The crystals are a vibrant red color and in the classic schalenohedral crystal form.  With the microscope I can make out one small crushed crystal right near one edge (appearing as white area) but overall the specimen is in very nice condition.  Keep in mind I am not backlighting these specimens or changing their color with any computer wizardry.  They are as one would expect the finest of this famous material to appear, in-hand.  It balances on edge for display but is not as stable as one would like.  A very nice piece  $2,900

A wonderful specimen although it is not the classic deep red color and schalenohedral crystal form.  This miniature is a vibrant, intense cranberry (deep pinkish red?) and has pinacoid terminations and stepped growth leading to these terminations.  It measures 3.9 x 3.8 x 1.8 cm and has no damage, less edge contacts.  A couple dozen crystals compose the piece.  This is a great example, again in an uncommon form.  Keep in mind I am not backlighting these specimens or changing their color with any computer wizardry.  They are as one would expect the finest of this famous material to appear, in-hand.  $3,600

This example is on a matrix of magnesite ore and is covered in an even druse of a slightly lighter red crystals that are totally transparent.  They are small, but are amazingly aesthetic.  The specimen is domical and views well from all sides.  It measures 3.8 x 2.7 x 1.7 cm and has one tiny chip on one very small crystal (only noticeable with close inspection and magnification), less edge contacts which are unusually clean.  The piece views nicely from several sides being quite three dimensional in nature.  Keep in mind I am not backlighting these specimens or changing their color with any computer wizardry.  They are as one would expect the finest of this famous material to appear, in-hand.  Fantastic piece!  $2,500

This one is very different from all the others in the collection in several ways.  First of all the crystals are a more even pink/ red color and they are on well crystallized magnesite? That creates a strong contrast in form and color.  Their form is very unusual in that they are stepped in their surface growth and often skeletal.  It is unknown what the tiny white and tiny clear crystals are.  This is an unusually large specimen measuring 7.5 x 5.5 x 3.5 cm and having a crystallized surface measuring 5.5 x 5.3 cm.  The surface is damage free and very aesthetic.  Keep in mind I am not backlighting these specimens or changing their color with any computer wizardry.  They are as one would expect the finest of this famous material to appear, in-hand.  Very unusual and attractive piece!  $4,000

OKH-981

OKH-981     Rhodochrosite    Tachwaneg Mine, Black Rock, South Africa (actually Black Rock Mine, Kalahari Manganese Fields, Northern Cape Prov., South Africa).  Ex. Paul and Dawne Dunning Collection.  Transparent rhodos in a well formed cluster with very little peripheral contact or damage (one termination on a peripheral crystal is cleaved).  Everything in main body of the grouping is damage free and attractive.  Terminations are dominated by pinnicoids but some are more complex which is the norm for the location.  Minor hematite blades add contrast to the high luster rhodos.  Good views from any side.  Currently mounted in a perky box.  1.5 x 1.3 x 1 cm overall.  Approximately a dozen crystals in the cluster.  If found available today these are usually seen as single crystals with strong contacts from once surrounding crystals.  This is a well developed, cluster with unusual terminations and all the other desirable qualities for which this material is so famous.  $570
