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-989

Back

OKM-989    Calcite Twin    Cumberland, England.  Ex. Harold L. Dibble collection.  Here is a nice find.  I think finding another as good for sale (at this price) anywhere would take some work!  This example is classic English material.  It measures 4.7 x 4.2 x 1.6 cm.  Small contact from matrix on very tip of base of twin.  Back of one wing shows a large contact from another crystal.  Great front view.  Good transparency, partial phantom, no damage.  $380

 

 

 

 

 

 

 

OKM-818

Bottom

OKM-818    Barite    Cumberland, England.  Ex. Harold L. Dibble collection.  A fine example of this classic material in an attractive matrix specimen measuring 11 x 9.5 x 6 cm.  Single and double terminated crystals of lustrous, transparent barite to 6.7 cm each are scattered nicely on the surface of hematitic matrix.  Some crystallization on back but it is minor compared to the display face.  A couple of the crystals are missing their tapered terminations due to what appears to have been contacts with other crystals or matrix.  I think the specimen is natural and is free of any human damage... an unusually thing for such an old specimen.  $3,000

OKM-809

OKM-809    Topaz     Virgem da Lapa, Jequitinhonha Valley, Brazil.  Ex. Harold L. Dibble collection.  This is a beautiful rich blue (images appear more washed out and lighter than the actual piece, also there are no green overtones, it is a true rich blue) natural topaz of very high quality.  The luster is exceptionally high showing no frosting or abrasion.  The accessory species is lepidolite and is sparse providing an attractive and not distracting highlight to this gemmy crystal.  Internally very clean for this material with no serious fracturing.  Views through to an etched backside that has some large smooth chipped regions that blend nicely with the etched regions.  One end is chipped and other fully terminated.  13.1 x 6.1 x 5 cm overall.  I've shown plenty of photos so you can determine if the backside damage distracts you.  I do not think it is distracting.  I feel it is a high quality example of rare to find material.  This specimen will include a custom engraved acrylic base.     P.O.R.
