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-812     Fluorite     Yaogangxian Mine, Bai Shi Du, Chen Xhou, Yizhang County, Hunan Prov., China.  Ex. Harold L. Dibble collection.  This specimen has what everyone is looking for in an exceptional fluorite of this size (the specimen measures 7.8 x 7 x 4.6 cm with the primary crystal measuring 3.1 cm on edge).  Fantastic mixed colors due to phantoms and being able to see through to the matrix in places.  All sides visible , at least in part, including the base.  Big crystal has a small attachment spot, natural, and not readily evident.  No damage, even to edges and smaller fluorites but one small quartz crystal appears to be missing.  Overall in fantastic condition for a specimen of this quality.  Great balance to the proportions of crystals and matrix.  Sits nicely.    The matrix is muscovite with an unknown mineral coating creating the gray staining on it.  Very high luster and much better in hand.  The material from this mine has become less and less common and never produced many specimens of this high quality, anyway.   $2,500

 

 

 

 

 

 

 

 

OKM-813

OKM-813    Barite     Avellan Mine, Mascif d'LEsterel, France.  Ex. Harold L. Dibble collection.  A pair of large, heavy, translucent crystals measuring 9 x 7.1 x 3.1 cm.  Large areas of the crystals are actually transparent.  Minor crystal modifications, no damage.  Great/ unusual location.    $450

 

 

 

 

 

 

 

 

OKM-814

OKM-814    Rhodochrosite    Starnitsa Deposit, Davidkovo, Rhodope Mountains, Smolyan Oblast, Bulgaria.    Ex. Harold L. Dibble collection.  This large plate of rhodochrosite measures 14.5 x 13 x 6.5 cm overall.  The balls of crystals are in two generations, the first forming casts after an unknown mineral and the second, of basically the same attractive pink color, being deposited on them.  The bottom shows the casts well and only one hollow area appears on the display surface exposing a cast.  Both interesting and aesthetic.  The base also is crystallized with pyrite and galena.  Zero damage to this big specimen is a real plus.  A wonderful rhodo.  $2,300

 

 

 

 

 

 

 

OKM-815

OKM-815     Aragonite     Lauzium Copper Mine, Greece.    Ex. Harold L. Dibble collection.  An attractive blue grouping of stalactitic forms and sharply formed crystals in overgrowth on them in some areas.  In hand it is very aesthetic and delicate looking.  It is easy to handle and not at all fragile.  This is very large for one of these measuring in at 12.2 x 10 x 6.1 cm.  Some stalactites are missing but it all appears natural (in-situ) and not to be damage.  A very nice piece!  $550

 

 

 

 

 

 

 

 

OKM-816

OKM-816     Tourmaline     Jose Pedra Mine, near Govenador Valadares, Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  A famous mine well known for some of the most colorful tourmalines around.  Now it is uncommon material, especially in specimens that are not all banged up.  This one is composed of stocky crystals with modified and pinnicoidal terminations in a tight grouping.  The accessory is mica, some appears pseudomorphed.  The cluster measures 4.6 x 4 x 4 cm overall.  Some edge contacts but all the primary crystals are in excellent shape (there appears to be a micro chip or two but only visible with magnification and even difficult to see then).  Vibrant bubble gum pinks and light to deep green, high luster and nice aesthetics.  $650

 

 

 

 

 

 

 

 

OKM-817

OKM-817     Tourmaline    Himalaya Mine, Mesa Grande, California.  Ex. Harold L. Dibble collection.  An attractive display piece of excellent color...deep purple, and gemmy through core and base, mild green middle and pink termination.  The crystal measures 9.5 x 3.1 x 2.8 cm overall.  It is highly striated and has a compound termination as can be seen.  The luster is excellent over entire piece.  There is damage along two sides as seen in the images.  It is enough to warrant the price asked here.  $700

 

 

 

 

 

 

 

 

OKM-974

OKM-974    Calcite, Fluorite and Barite on Sphalerite    Carthage, Tennessee.  Ex. Harold L. Dibble collection.  I have sold many, many hundreds of these specimens over the years and I think this is actually the finest miniature I've handled.  Why?  1.  The twinned calcites are double terminated and damage free (less a tiny INTERNAL crack at the termination of one) and transparent, 2. All four species for which the locality is famous are present in this small specimen.  3. It is very aesthetic, in-hand,  4. The luster is excellent.  Impressive in all regards.  6.5 x 5.1 x 3 cm.  This specimen will include a custom engraved acrylic base.      $1,400

OKK-863     Garnet     Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  This little beauty appears to be internally gem material.  Deep orange color, no damage, great form.  Surface texture, color and shape will probably give its new owner plenty to go on to get a more precise location.  1.5 cm diameter.  $40

OKK-864    Sulfur    Steamboat Hot Springs, Nevada.  Ex. Harold L. Dibble collection.  Large 3.1 x 2.1 x 1.6 cm single crystal.  Translucent, double terminated, no damage and highly skeletal.  Interesting location.  $30

 

 

 

 

 

Galena and Dolomite       Buick Mine, Viburnum Trend District, “Big Bear Trend”, Iron County, Missouri. 

You may have seen these in larger sizes with the other big dealers (at big prices) and noted their uniqueness.  Many are spinel law twins and even more interesting, many are bar shaped crystals instead of the traditional cubes.  All of the ones I am offering are floaters and damage free, unless otherwise stated.  I have a fine group of well-priced thumbnail sized specimens here for your consideration.
