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-998      Quartz     Tizirine, Oudrzazate, Morocco.  Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 84 By Harold Dibble.  A fine stalactite from an unusual locale.  This specimen measures 11.5 x 4.8 x 4 cm.  Very high luster (better than my images indicate), zero damage, sits on end (at an angle leaning forward, however), and displays great.  There is minor, lustrous calcite overgrowths near the terminations of stalactites.  The quartz looks light purple but is actually clear and the purple seems to be below the largest, final coating of crystals.  The crystals of quartz are included by goethite needles adding to the aesthetics of the specimen.  This specimen will include a custom engraved acrylic base.  A great looking specimen!  $950









OKM-100    Fluorite, Quartz and Dolomite    Lieyang, Hunan Province, China.  Ex. Harold L. Dibble collection.  An attractive green cube modified by dodec faces.  Amazing clarity.  Back of fluorite shows contacts from other crystals and a chip/ crack.  Frontal view is very nice, however.  Bright luster on all the species.  $80









OKM-102     Fluorite    Frazer's Hush Mine, Rookhope District, Weardale, Durham, England.  Ex. Harold L. Dibble collection.  Beautiful, vibrant green crystals to 1.7 cm on edge each.  The main crystals are twinned.  Minor chipping as seen in close-up but in had it looks really nice.  Excellent transparency throughout the main crystals and inclusions in base/ surrounding crystals.  The twins stand up nicely.  7.7 x 6.5 x 5.4 cm overall.  Excellent historic piece.  $700








OKM-103      Fluorite with Calcite    Naica, Mexico.  Ex. Harold L. Dibble collection.  A large example of this popular, well known, desirable material.  It measures 10 x 8.8 x 4.2 cm overall with both cubes and highly modified "Aztec pyramid" style crystals.  In fact, much of the crystal is actually the side of one very large pyramid style crystal.  No damage to body of piece.  Fantastic clarity is not very evident in the images but the interior would be described as gem throughout  A couple tiny chips right on edges as would be expected... really clean, even the edges are much better than would be expected.  Tetrahexahedral? modifications to many corners on crystals.  This is an exceptional piece for the location.  The calcites are small white bladed crystals found on one side/edge of the piece.  Very nice.  $650









OKM-104    Rutile and Hematite in Quartz     Novo Horizonte, Bania, Brazil.  Ex. Harold L. Dibble collection.  Wonderful, slightly smoky points with just the right amount of long, robust rutile crystals within.  The hematite blades compose much of the base but most do not extend into the crystals visible on top.  One tiny tip ding on the main, double terminated crystal is a real shame as this would be an unbelievable piece if not for that blemish.  Still a real looker and desirable material.  Could use a bit more cleaning.  $375









OKM-106      Fluorite with Pyrite    Naica, Mexico.  Ex. Harold L. Dibble collection.  A big, clear main octahedral crystal with riders and pyrite crystal inclusions.  It measures 7.7 x 6.4 x 5 cm with the main crystal measuring 4.9 cm on edge.  Base and some edge contacts.  Some contacts are healed, some not.  Main display view is nice with all visible terminations being clean.  The inclusions are nice crystals to several millimeters each.  $350









OKM-107      Adularia and Chlorite   Val Crystallina, Lukmanier, Graubunden, Switzerland.  Ex. Harold L. Dibble collection.  A large well formed group of twins on minor matrix.  6.7 x 4.3 x 3.;3 cm overall.  Several small chips are present.  Minor chlorite inclusions.   $190










OKM-109     Fluorite      Blackdene Mine, Weardale, Durham, England.  I suspect that this is a rather old specimen...  8.5 x 8.2 x 3.7 cm with cubes to 3.2 cm on edge.  Minor chipping throughout but not in what most would call bad condition.  The big twins are doubles, with two sides showing the penetration.  I've seen these in the literature but do not remember what to call them.  I have not seen this in contemporary material from anywhere.  Small, ugly etched calcite in center of piece.  Great clarity and surface have mixed luster with corners being clearer (much like "Carthage Corners" seem on Tennessee material.  The first $300 gets it.









OKM-111      Barite and Calcite     Silius, Sardinia, Italy.  Ex. Harold L. Dibble collection.  10 x 7.7 x 4 cm.  Largest crystal 2.6 cm.  These barites are yellow, transparent and thickly bladed crystals.  Two spots show some damage but overall in decent condition.  The calcites are white and mostly transparent.  Interesting piece and locality.  $325










OKM-112    Galena with Calcite     2nd Sovietsky Mine, Dal'negorsk, Russia.  These fine spinel law twins are the classics now rare to find (the Bulgarian material is now dominating the market).  This one is a floater with one small ding/ cleave on one edge.  The ding can be seen clearly from back on top left edge in pic.  Obviously not a big deal when one considers how unusual a floater of this material is.  It will show as damage free if displayed as it is shown in my hand (third photo) or in other frontal positions like the first image.  Calcite coats almost all of the backside.  8 x 6 x 2.3 cm.  Great twins of this classic lustrous material.  $450










OKM-114      Stibnite     Maramuries Co., Romania.  Ex. Harold L. Dibble collection.  9 x 5 x 5 cm grouping with numerous sprays of crystals.  In good condition but not a piece to be handled much or shipped.  Excellent luster and nice terminations.  Special arrangements will be need to be made for delivery.  $200

OKM-115     AdulariaGrison, Graubunden, Switzerland.  Ex. Harold L. Dibble collection.  Wow... a matrix specimen with no chlorite incluseions, the highest luster the species could have and fantastic form.  The grouping is twinned and no damage to front, top sides (back sows minor contact so that's the side I'd consider the back).   9 x 7 x 4.6 cm overall.  Of the dozen or so adularia specimens in this collection, this one was the finest.  Fantastic display qualities!  This is a top shelf specimen that I suspect would be far more expensive from other dealers.  $750
