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-121     Tourmaline, Quartz, Muscovite     Virgem da Lapa, Minas Gerais, Brazil.    Ex. Harold L. Dibble collection.  An interesting piece that was likely a floater.  Many tourmalines of various colors and subtle shades, ...pinks and greens dominate.  Most crystals are nicely terminated but several are broken off.  Still an interesting and uncommon find.  There is one chip on the double terminated quartz crystal.  Tourmalines to 4.5 cm each.  Piece measures 9.2 x 5.2 x 4 cm.  Displays nicely.  $450










OKM-122      Quartz  and Andradite     Sinerechenskoye, Blue River Deposit, Primorsky Kray, Russia.  Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 43 and 46 By Harold Dibble.  One photo is a full page figure.  Prase quartz such as this widen toward the crystal's termination and all the crystals in this magnificent cluster show this characteristic.  I believe it is actinolite inclusions (hedenbergite) that give these quart specimens their attractive green color.  The quartz are very large and well formed for the location.  The garnets are small, but the simple fact that they are in combination in a multi crystal matrix cluster that is aesthetic and free of damage is a very rare thing.  This grouping measures 10 x 8.5 x 8 cm and the longest crystal is 7.5 cm.  Edge crystals where contacts were present are gone as would be expected.  $2,200








OKM-123    Morganite    Minas Gerais, Brazil.    Ex. Harold L. Dibble collection.  A good specimen of this difficult to get material.  Front side is first photo showing only one tiny chip.  Back side has numerous chips.  Front and back are modified and those faces are striated (rather unusual).  The striations are obvious on the back and very light on the front.  The single crystal was once on clevelandite and some remains embedded in it's base.  Some black tourmaline inclusions but much of the internal material is gem or gem material with fracturing.  The piece measures a healthy 10.5 x 6 x 3 cm.    $2,500








A bluish case detected here is unrealistic... the crystal only shows shades of green and pink.

OKM-124    Toumaline on Quartz     Nuristan, Laghman Prov., Afghanistan.  Ex. Harold L. Dibble collection.  A complex tourmaline composed of soft greens and pinks.  It measures 7.3 x 7 x 5 cm.  Excellent condition overall with the main tourmaline having only a tiny chip that is difficult to find.  The front view is fantastic and contacts from matrix are isolated to the back of specimen.  All the tourmalines have glassy luster.   A fine display piece.   $2,500









OKM-125   Polished Quartz   RESERVED       Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 74 By Harold Dibble.  This piece has obviously been preserved to show the phantoms within.  No damage, nice polish and outstanding phantoms.  Stands upright and measures 10.1 x 5 x 3.7 cm.  $350










OKM-126     Quartz    Galileia, Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 80  By Harold Dibble.  This is a complex shard from a very large crystal showing parallel growth of surface features.  Damage free floater.  Interesting to look at and much of it is clear with a slight smoky tint.  Glassier looking than the photos seem to indicate.  9.1 x 5.1 x 1.3 cm.  $225










OKM-127     Quartz      Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  A 10.4 x 6 x 5.3 cm single crystal.  Healed surfaces, no damage.  Front very nice with secondary quartz that is glassy and slightly smoky over an original, ugly, crystal.  Muscovite sticking out on one side in lower region of crystal.  Stands for display.  Nice.  $200











OKM-128    Tourmaline    Brazil.  Ex. Harold L. Dibble collection.  Wish I had a better location but that is all there was and I'm just not positive on where it is from.  It is a substantial specimen, however, measuring 14.4 x 5.1 x 3 cm.  It is a shard from a much larger crystal, single terminated, and a combination of colors.  The luster is very high and there is no damage to the display surface.  The color is most evident when back lit and it ranges from a medium red to a nice blue.  An attractive specimen.  $400










OKM-129    Quartz     Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 49  By Harold Dibble.  8.5 x 3.5 x 3 cm single crystal of beautiful color and interesting form.  Tiny tip ding with internal crack.  A couple other tiny scuffs, too.  Too bad.  It still took an excellent photo for Harold's book when positioned right.  Very high, glassy luster, pleasing tint and internally transparent.    $300










OKM-130    Quartz     Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  Another crystal shard that is fully healed with complex surface features on both sides.  Gemmy internally.  One chip.  $175









Large Enhydro.

Large Enhydro.

OKM-131    Quartz     Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  Beautiful "window quartz" with clay inclusions.  A huge ENHYDRO in this one.  The bubble when stretched out and moving is about a cm long.  It moves about 2.5 cm within a triangular shaped opening.  It is near the surface and can not be missed!  Strong base contact, otherwise in good shape.  The internal features are numerous and not something I can show well in photos.  Great piece.  $395










OKM-170    Manganocalcite    Casapalea, Lima, Peru.  Ex. Harold L. Dibble collection.  Approximately 17 x 10 x 10 cm piece with endless clusters of beautifully terminated crystals.  Back is very nice also with sphalerite, pyrite and quartz.  With a lope some very minor damage can be found but this specimen is in outstanding shape for its size and displays as damage free unless very carefully scrutinized.  This is one of the nicest examples of this material that I have seen.  I won't ship this specimen, arrangements for deliver will need to be arranged.  It will likely need to be picked up at one of the shows I attend.  Great piece.  $2,000









Back view


OKM-172    Calcite     Copper Queen Mine, Bisbee, Arizona.  Ex. Harold L. Dibble collection.  A large domical cluster of crystals on a cast after??  I've checked it all out with 10x and it appears damage free (somewhat of a miracle given how fragile the blades look).  Not as fragile as it looks as I have transported it hundreds of miles and handled it numerous times never having any issues.  Displays well from any side.  One side shows another species as a brown overgrowth.  That side isn't as aesthetic.  Attractive green color and good luster.  13 x 10.7 x 7.9 cm.  At one time there were quite a few of these available on the market.  Seldom were they this nice.  How many have survive intact?  This one is the nicest I have seen.  $1,800










Close up of front center

OKM-171     Goethite      Florence Mine, Egremont, Cumberland, England.  Ex. Harold L. Dibble collection.  The classic location for this famous material.  "Kidney Ore"   This monster is a museum sized piece measuring in at 27 x 17 x 9 cm overall.  It is difficult to handle and difficult to display as it is probably about 20 pounds in weight.  Front and back are both damage free.  Calcite overgrowths on surfaces once attached to matrix and one small calcite cluster in the front adds some interest.  Not scuffed up, chipped or abraded in any way.  Beautiful, high quality piece.  P.O.R.
