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. 



OKN-324      Calcite      Potasi Mine, Santa Eualia District, Chihuahua, Mexico.  Ex. Harold L. Dibble collection.  A large cluster of these hematite included and coated crystals that measures 16.5 x 12.2 x 5.6 cm.  It has good luster which is not evident in the images and interesting overgrowths on selective faces.  This material was once readily available to collectors but no so any longer.  This is one of the nicer clusters I have seen from the location. Very clean with no damage.  Edge contacts are also very nice except the on facing forward in the first image.  This could be trimmed off if found distracting.  Excellent quality! $400

Front view but laying sideways

OKN-325      Celestine       Maybee, Michigan.  Ex. Harold L. Dibble collection.  A large grouping of several double terminated crystals.  The piece measures 16.7 x 7 x 7 cm overall.  The crystals are in fine condition and all are lightly embedded in a small section of matrix.  The base of the matrix has one broke crystal facing downward (this is seen in the first image which is the back of the piece) as would be expected.  It displays damage free if positioned with the matrix downward (which is frankly impossible without a custom base or stand).  These big, fine crystals make the specimen top heavy so Harold had it lying on its side for display.  $425







OKN-328      Fluorite with Pyrite Inclusion     2nd Sovietskii Mine, Dal'negorsk, Primorskiy Kray, Far-eastern Region, Russia.  A fine example of these now famous fluorites measuring 10 x 6.5 x 6.1 cm with cubes to 3.7 cm on edge.  A few cute pyrite crystal inclusions along with enhydros and enhydros with bubbles.  No damage, minor internal fractures, minor base contact.  Displays great and sits nicely on base area.  The crystals are cubes modified by dodecs.  They are gemmy with surfaces that show the characteristic frosted surfaces associated with this material.  A beautiful, high quality specimen!  $500
