Just Acquired

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-126

Back

OKN-126     Quartz     Sierre Blanc, Lincoln County, New Mexico. Ex. Harold L. Dibble collection, previous provenance unknown.  BIG New Mexico quartz specimen.  All sides crystallized so it could be positioned differently than I have photographed it.  The base facing down is the poorest surface so that is why it is photographed the way it is.  Likely position for display would be with the largest crystals at top or facing upward.  There is some damage but given the size of the specimen it would be nearly impossible not to have some points missing.  Not fragile but difficult to handle because of its size.  I will not ship this specimen, it would need to be picked up from me at a mineral show or other arrangements would need to be made.  Multiple phantoms in some crystals.  This would be a focal point in any collection, especially one specializing on the American Southwest or New Mexico in particular.  The piece measures approximately 26 x 22 x 18 cm.  Longest point is 10 cm.  There is lots here to be appreciated.  $1,300

Back

OKN-127     Quartz     Coronel Murta, Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 86, by Harold Dibble.  A triangular shaped piece that is 18 cm on edge.  Crystallized on all sides.  The largest, top crystal (the one on left in forth pic) has a large bubble enhydro that moved within a 1 cm opening.  The bubble is approximately .3 cm.  Numerous clay inclusions.  There is minor chipping on edges of piece and on one of the numerous terminations so it isn't perfect... but it is really nice for a specimen of this type.  No distracting issues and completely crystallized on back, as well as front.  More impressive in-hand than I can portray in the photographs.  $950

 

 

 

 

 

 

OKN-128

OKN-128    Tourmaline on Quartz   Cruzeiro, Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  Dark green, translucent, lustrous tourmalines all over a large quartz crystal.  The tourmalines are nicely formed, deeply striated, up to 7 cm in length but many are not terminated.  The quartz is poorly formed and milky in color.  The main spray of crystals in the center are nicely terminated.  Sounds like a train wreck but it is actually a desirable specimen and typical of material from decades ago.  14 x 11.5 x 8 cm along edges.  Over 17 cm diagonally.  Sawn flat base so it sits well showing off the tourmalines on all sides and top (nothing decent on back of specimen).  I think someone will have a place in their collection for this substantial specimen at this price.  $400
