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-204

OKM-204      Quartz Gwindel      Goschenen, Uri, Switzerland.  Ex. Harold L. Dibble collection.  For a change a small gwindel quartz... only 4.2 x 3 x 1.6 cm overall.  One edge shows contact and some minor chipping.  Good transparency, even smoky color, obvious twist all make this open gwindel a fine example but not a showpiece costing thousands.  $250

OKM-820     Quartz   Brazil.    Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 83 By Harold Dibble.  This fine specimen is a full page figure in Harold's book, and an impressive quartz specimen in and of itself.  It is a floater measuring 17.6 x 11 x 7.5 cm.  The crystal is double terminated, has a medium to high luster on it's upper display surfaces and a lower luster on what I would call its base (back side).  There are several chips as seen in the images so it is in good, not great shape.  The surface growth features are quite amazing and even better in person.  Everything here is in parallel growth on the one crystal.  $1,200

 

 

 

 

 

 

 

OKM-824

 

OKM-824     Fluorite on Dolomite    Leiyang, Hunan Prov., China.    Ex. Harold L. Dibble collection.  A large example of this now famous material measuring 14.9 x 9 x 7.5 cm with crystals to 2.2 cm on edge.  Light purple cores dominated by clear overcoats comprise these fluorites.  Cubes modified by dodecs.  Nice form, crystal separation on matrix, luster and crystal coverage.  No damage.  This one would be much higher in price in most cases.   $650

 

 

 

 

 

 

 

OKM-821

 

OKM-821     Quartz Stalactites with Stilbite and Calcite     Jalgaon, India.  14.4 x 5 x 5.1 cm network of light blue quartz stalactites with a 2.6 cm double terminated stilbite and several smaller clear calcite rhombs. Very impressive example with no damage and only the smallest of attachments.  Minor hot glue on one terminal end of a stalactite.  Great luster and sculptural form set this Indian specimen way ahead of most.  Translucent and lots of sparkle from the micro quartz coatings on the stalactites.  And for material of this style it is exceptionally fine.  Quite impressive.  $375

Back?

OKM-824      Quartz    Brazil.   Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 75 By Harold Dibble.  This large cluster at first glance has an Arkansas look to it... lots of tabular, double terminated, clear to milky crystals compose this large, 16 x 11 x 8 cm cluster.  The damage is minor with two spots on the front showing crystal breakage and back and a few more.  Overall in nice condition as Harold's book and the images show.  High luster well formed crystals without distracting qualities such as staining, contacts, etc.  $700

OKM-210      Quartz cast after Calcite    Droujla MIne, Laki Deposit, Rhodopi Mt., Bulgaria.  Ex. Harold L. Dibble collection.  Attractive, white, high luster quartz casts with yellow tips.  The tips of cast appear yellow because inside they are filled solid in those areas with another mineral that has a yellow cast to it (possibly dolomite).  Interesting and far more attractive in-hand that my images indicate.  No damage.  $150
