The Harold L. Dibble Collection

Harold Dibble, is the author of "Quartz: An Introduction to Crystalline Quartz", and was a well known east coast collector.  He passed in 2014 and his collection of fine minerals will be offered in upcoming months.  Some of his most important specimens grace the displays in the Seaman's and Smithsonian museums.  Harold's passions also included art and he was early in recognizing minerals as Nature's works of art.  Many of his minerals reflect this ideal. 





OKM-976     Calcite Scepter      Bor Pit, Dal'negorsk, Russia.  Ex. Harold L. Dibble collection.  3.3 x 1.4 x 1.4 cm floater.  These calcites were once on the market like so many other minerals... not any more.  This one is an interesting dumbbell form.  No damage.  $220








Back or Bottom

OKM-978     Calcite   Auglaize Quarry, Junction Ohio.  Ex. Harold L. Dibble collection.  The finest of these that I have owned... super high luster, just like the best Carthage, Tenn. calcites, and composed of damage free crystals of good translucence with transparent areas.  Individual crystals to 4.6 in a cluster measuring 6.4 x 6.2 x 3.5 cm.  Slightly yellow tips.  This is so nice it could pass for a Carthage specimen.  Field collected by famous Ohio field collector John Medici.  Contact to bottom (or it could be the back of the specimen) only.  This is a great price for a miniature of this quality.  It is exceptional in every regard for material from this locale.   $350










OKM-979     Fluorite on Quartz coated Barite     Rosiclaire Level, Minerva Mine #1, Cave-In-Rock, Illinois.  Circ. 1994.  Ex. Harold L Dibble collection.  Translucent purple fluorites to 1.6 cm on edge embedded in barites with bright shiny quartz druse.  Damage free, interesting growth hillocks on fluorites, edge contact, minor quartz on one fluorite cube.  6 x 4.4 x 3 cm.  $175










OKM-980   Calcite with Dolomite casts     Tsumeb Mine, Tsumeb, Namibia.  Ex. Harold L. Dibble collection.  This 7 x 5 x 5 cm calcite cluster is dominated by a rhomb (the largest) measuring 2.7 cm on edge.  The clear calcites have overgrown brow, I assume hematite stained, dolomite casts.  Excellent condition with only a very little scuffing on the edge on a smaller crystal.  Most of the white spots wiped off after the pics were taken.  A quality Tsumeb specimen.  $300








OKM-982    Calcite Twin    Dal'negorsk, Russia.  Ex. Harold L. Dibble collection.  4.5 x 1.4 x .8 cm clear crystal of calcite.  Nicely twinned and striated.  Small attachment at base, no damage and mounted on an acrylic base.  $95










OKM-983     Wulfenite    Los Lamentos, Mexico.  Ex. Harold L. Dibble collection.  This is the finest small cabinet specimen of this material we have handled (and we've had many!).  It is damage free with large, highly lustrous, translucent, butterscotch colored crystals to 1.3 cm on edge.  7.1 x 6 x 4 cm overall with crystals everywhere.  Bright, vibrant color with no staining.  Fantastic, desirable, aesthetic example.  This specimen will include a custom engraved acrylic base.      $2,500










Mild backlighting

OKM-984    Fluorite    Cave-In-Rock, Illinois   Ex. Harold L. Dibble collection.  A yellow cube  with a thick purple overgrowth.  Excellent color with very minor edge chatter.  6.8 x 4.8 x 3.5 cm.  Contacts on back and a small area of one side.  Nice example.  $290










OKM-985     Magnetite  SOLD    Snake Hill, New Jersey.  Ex. Harold L. Dibble collection.  A fine octahedral crystal that has the typical surface complexity notable of the area.  Embedded in matrix with a smaller crystal.  It is complete and damage free.  The big crystal measures 1.5 cm on edge and the piece measures 4.8 x 3 x 2.4 cm.  Difficult to find in good specimens like this one.  $80










OKM-986    Willemite     Parker Shaft, Franklin, New Jersey.  Ex. Harold L. Dibble collection.  Prev. Caswell specimen (an important classic collection).  A nice highly fluorescent rock with a fine historic provenance (includes original tag) 5.5 x 5 x 2.6 cm.  $60










OKM-987     Fluorite    Shang Bao Mine, Hunan Province, China.  Ex. Harold L. Dibble collection.  A small cluster with transparent cubes to 1.1 cm each.  It measures 4.8 x 3.6 x 2.5 cm overall and is damage free.  Extremely high luster, great form and exceptional color.  A very bright, fine miniature.  Top quality and even better in person.   $250









OKM-988     Celestine    Maybee, Michigan.  Ex. Harold L. Dibble collection.  A cluster composed of light blue (sorry, it is not evident in the images), double terminated crystals to 4.5 cm each.  they are interlocked in a group measuring 5.5 x 5.3 x 4.8 cm.  Only one crystal's edge shows any contact so it is almost a floater.  No damage.  Great quality.  $200











OKM-991     Barite      St. Saturnin, Puy de Dome, France.  Ex. Harold L. Dibble collection.  3.5 x 2.8 x .9 cm single crystal.  Sceptered in form, totally gemmy, nice light amber color.  Complex and interesting.  Mounted on an acrylic plate.  No damage. $80










OKM-992    Brazilianite    Mendes Pimentel, Minas Gerais, Brazil.   Ex. Harold L. Dibble collection. An attractive sulfur yellow primary crystal that is gemmy with a couple of translucent attachment crystals and other minerals in base.  3.8 x 3 x 2.8 cm overall.  Edge contacts and chipping on attached crystals but main crystal is nice.  A very good example of this material.  $120









OKM-995     Cerussite   Tsumeb Mine, Tsumeb, Namibia.   Ex. Harold L. Dibble collection.  A fine, complex twin from this historic site...not uncommon material but this one is more interesting than most.  Using 10x I find one branch cleaved off but no other damage.  A really interesting matrix specimen measuring 5.5 x 4.3 x 3.2 cm.  $600









OKM-996    Diopside     Orford Nicel Mine, Quebec, Canada.   Ex. Harold L. Dibble collection.  I used to get these all the time for resale but seldom do any more.  This is a good example measuring 5..5 x 1.5 x .8 cm.  No damage.  Excellent luster.  $45











OKM-997    Quartz    Dal'negorsk, Russia.  Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 61 By Harold Dibble.  This specimen is thoroughly discussed in regards to the obvious... interrupted growth.  Transparent in upper regions and light veils in lower areas.  6.8 x 2 x 2 cm.  No damage.  $400









OKM-973     Herkimer Diamonds      Ace of Diamonds, Middleville, New York.  This bag of Herks weighs 125 grams and contains crystals from .2 cm to 2.7 cm each.  Most are water clear with no inclusions but some have minor inclusions as seen.  They were collected by myself and have not been rolled around and abraded.  The close-ups represent a random grab... not the best and are representative of the entire lot.  Jewelry grade material.  Very fine crystals like these always sell fast to dealers who parcel them out at far higher prices.  They would be great for a collector's display surrounding one of your large, special, Herkimer diamond specimens.  I will wrap these carefully for shipping so no damage is incurred.  $4 per gram for a total of $500
