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-970    Calcite with Chalcopyrite     Brushy Creek Mine, Greeley, Viburnun Trend, Reynolds County, Missouri.  Ex. Harold L. Dibble collection.  A very famous find well described in the literature (see Les Presmyk's article in Rocks and Minerals, Nov/Dec. 1997).  A large 21 x 17 x 11 cm specimen which sits at an attractive angle.  Great luster (has a wet look to it) and aesthetic form.  The luster is not so evident in my images but it is certainly of the highest luster to be obtained in the gray variety of crystals from this find.  A couple minor tip cleaves are there and not distracting and in the overall appeal of this museum class specimen.  Most would consider the piece to be in very good shape.  Easily the nicest I have owned and the nicest I have seen outside a museum.  This piece has a big visual impact.  $3,000
