CATALOGUE  
                                  (CORUNDUMS AND OTHER MINERAL SPECIMENS FOR SALE)
 
 
 
       It has been so much fun collecting that we decided to see if selling would bring similar enjoyment.  Through numerous friendships struck over the years, I think we have a good head start and hope you agree.                                                                                                                                                    
       Please take a look below at our Indian minerals, including some rare and superb "arborescent" pentagonites!  These are some of the finest I have seen. 
       The corundum specimens shown in the PHOTOESSAY and GALLERIES are not for sale, but many similar fine ones are.  We shall soon have another section devoted to these.  In the future, we will show photos and develop a detailed list of available specimens.  I can send JPG's of anything we have that you would like to see.  We also are willing to assemble suites of specimens according to your preferences.  Just let me know by email at  <collector@corunduminium.com>  what you are interested in.
      At this initial stage, over 1,000 corundum specimens, plus hundreds of specimens of other minerals that will be available.   Below is a mere sample.  As you see, the specimens range from ugly to the finest museum pieces.
      I am not able to take credit cards, but can take PayPal payment over the Internet.   Cash or bankable check is preferable (though in some cases funds would have to clear before shipment).   We will ship by insured Priority or First Class U.S. Mail anywhere in the U.S. for the quoted price.  Please contact us if you prefer another destination or mode of delivery.
 
MINERALS OF INDIA    [Work in progress; locality data, other details to follow (8/11/05)]
       The Deccan Plateau is known for basaltic lava flows which contain pockets often lined with zeolites and associated minerals.  Contractors excavating primarily for road gravels have learned how to detect and exploit these pockets; and the results are some of the World's most fascinating specimens.
  Cavansite:  Huge (relatively speaking) ball of radiating terminated crystals, slightly more than one inch in diameter, from the Wagholi Mine, Poona, India.  [#41;  $1,150]
Pentagonite:  "Arborescent" cluster of terminated crystals of this variant of cavansite - an extreme rarity!  Height of the cluster is  approx 1-3/8 inches.  [#42; $2,650]  
  Calcite stalactite, approx. 5-1/2 inches long.  Highly translucent to gemmy.  It is "missing" one radiating crystal, but unless you look closely you would never know where it was attached.  [#24; $400]
This 7 inch long drusy quartz stalactite is peppered with tabular crystals of stilbite - and it shows no dings!  [#1; $450]  
     "Green stilbite".  This rarity is probably colored by chlorite inclusions.  Diameter of cluster is approx. 3 inches.
Prehnite with apophyllite.  This network of pale green prehnite (pseudomorph after laumontite?) has numerous attachments of white apophyllite (the sharp rectangular solids).  Diameter of the specimen is approx. 4  inches.  [#9; $375]  
  Powellite on scolecite.  Well-formed powellite crystal approx. 1/2 inch on an edge, in radiating crystals of scolecite - a great rarity!   Specimen diameter is approx. 2-1/2 inches.  [#8;  $850]
Green calcite (new find - only a few decent specimens in existence).  Lovely, pale green cluster of completely terminated crystals approx. 3 inches long by 2 inches deep by 1-3/4 inches high.  [#12; $850]  
  Chalcedony with stilbite.  This aesthetic specimen of icy clear chalcedony and salmon-colored stilbite crystals is one of my favorites.  It stands about 2-1/4 inches high.  [#6; $500]
Apophyllite.  This is a superb specimen from a recent find.  Gem crystals of this habit and rich lime green color are quite rare.  Many on this 5 inch long specimen are "water clear"!  [#25; $2,950]  
  Apophyllite and Stilbite.  This 5-3/4 inch long specimen has numerous tabular green apophyllite crystals competing for space with pinkish orange stilbite crystals.  [#15; $750]
     
 
Himalayan Corundums
Hunza Valley, Pakistan:   Purple sapphire DTXLs in matrix, translucent to gemmy, euhedral, mirror faces, thumbnail to about 2" diameter matrix ($20-$250) (rare until last year, but recently they are becoming more common).   Jegdalek, Afghanistan: Ruby XLs in white calcite (classical material, recently found).         
 
   Chumar Mine, Ganesh Himal, Nepal:  The Chumar Mine, developed around 1980, produced very little material, but its best specimens are among the finest crystalline clusters in the World.  We have a few recent specimens available, from micros to a 1" cluster (right), and a few larger matrix specimens ($5-$500).   The northeastern Taplejung region of Nepal is beginning to produce interesting pale to medium blue sapphires ($25-$200).
 
 
Indian Corundums
 
Karnataka (Mysore) Province occasionally produces very large ruby crystals.  Some are opaque brownish red; but a new discovery produced subtranslucent "wine purple" crystals (see also photoessay).  A  few of these extremely rare monsters (from about 5 to 16-1/2 pounds - see left) are available ($1500-$10,000).  Tapered star rubies, domed to show asterism, but not of great color, are common ($5 -$20).  
 
    A few "watermelon rubies", nodules of a blue mineral of as yet unknown composition containing ruby corundum, were found in fuchsite schist ($10 - $500).  I have occasionally seen this material alleged to have originated in Tanzania, but am unaware of any deposit there.
 
Sri Lankan Corundum
  Small crystals, mostly gemmy pale to medium blue or pale yellow, but a few with "fancy" colors - nothing really great here to spare ($20-$100).    
 
Burmese Corundum
  From entire lots or collections of Burmese material (from various localities in Mogok, Mong Hsu, etc.) purchased, there are many interesting ruby and sapphire specimens. Most are attractive, and some are higher end - something for everybody wanting Burmese corundum!  Prices range from $10 to $10,000.  
 
     
Brazil    
       Though noted for its spectacular minerals, Brazil is not a well-known corundum source.  Two mines produced fine cab grade ruby and sapphire; and the miner of both saved the best crystals, which we were able to purchase for the collection.  Needless to say, these are rare.  Sapphires are about $2 per gram; rubies (not as nice habit, but superior as rough), about $10 per gram.  
     
     Dark green emeralds are perhaps Brazil's most highly regarded gemstone, and years ago I stumbled across some huge ones!  The largest single crystal (left) is the size of a spray paint can, and is slightly translucent (the smaller broken and healed interpenetrant twin is totally translucent)!  The plate (right) is approximately 12" by 15", and most of the crystals show rich color and good translucency.  Several other interesting but less expensive pieces are also available.    
     
Miscellaneous    
    There are other individual specimens and lots (corundum) from diverse localities;  fluorites (Medoc, Ontario; China), some cabinet celestites (a geode of water clear crystals from Madagascar, and a trio of U.S. with three different habits); tourmalines, arborescent silver micros and thumbnails (mainly, Zacatecas; but a few minor Kongsbergs); and a few hundred "rock shop front bin" quartzes, garnets,... .  Inquire.    
 
Consignments
      The only thing at this time is the Indian carving of the "Ganesha" illustrated in the photoessay (which weighs about 45 lbs.; for $10,000, which works out to about ten cents a carat); but arrangements are being made with my foreign colleagues for some interesting and outrageous minerals.  See also "LINKS" for items offered directly; and keep your eye on this page for updates.
