OKN-765     Rutile in Quartz    Brazil.  Ex. Harold L. Dibble collection.  This aesthetic specimen measures 10.1 x 7 x 5.4 cm overall and has hematite crystals to over a cm and rutile crystals to 6.5 cm in citrine colored quartz.  Very clear, very easy to see the desired details internally.  Polished front and one sawn edge.  Remainder is natural.  Back is dominated by contacts from other crystals which gives the piece an attractive background to the rutile and hematite.  Sits perfect.  Excellent condition, a really fine display piece.  Uncommon to see rutiles this robust and attractive.   $450








OKN-766     Hematite on Quartz      Wawa, Ontario, Canada.  Ex. Harold L. Dibble collection.  Very, very dark purple or smoky quartz makes the piece almost appear black.  Nicely formed balls (hemispherical) attached to their surfaces.  Edge ctact as seen but crystals internal to the piece are damage free.  4.6 x 4.5 x 3 cm.  Some Styrofoam on bottom of specimen.  $50








OKN-767     Danburite     La Aurora Mine, Characas, San Luis Potosi, Mexico.  Ex. Harold L. Dibble collection.  A typical crystal for a popular occurrence.  This on measures 7.2 x 3 x 1.8 cm and is gemmier than most.  Good regions for faceting if desired.  The termination has two small chips as seen otherwise the piece is in good condition.  $40









OKN-768      Quartz (variety Ametrine)      Santa Cruz Province, Bolivia.  Ex. Harold L. Dibble collection.  This is a termination that has been polished to show the interior detail, especially the mixed purple and yellow color.  The yellow is minor in comparison to the purple which is normally the case with material from here.  8.2 x 8.2 x 5.2 cm.  Back has a couple chips but that certainly is not the side one would display.  The polish is excellent and it sits well several different ways.  $60








OKN-769    Quartz   RESERVED  Coleman’s Mine, Arkansas.  Ex. Harold L. Dibble collection.  A fine cluster measuring 10 x 7.1 x 5. 4 cm with crystals to 6 cm each.  I’ve searched and only find one crystal with a ding on its backside.  Outstanding condition overall given how much is here and vulnerable to breakage.  It dispalys damage free and sits well on a section of flat base or other ways.  Great views all around.  Top grade quartz from this prolific locality.  $90







OKN-770     Galena, Sphalerite, Quartz, Chalcopyrite     Dal’ negorsk, Russia.  Ex. Harold L. Dibble collection.  An attractive assembalage od species measuring 7.9 x 4.9 x 4.1 cm.  No damage, attractive high luster crystals.  Good for the location.  $175








OKN-771     Cinnabar on Dolomite      Fenghuang, Hunan Province, China.  Ex. Harold L. Dibble collection.  A good piece for this once prolific locale.  The primary crystal measures 1.2 cm across, is complex in form, transparent to translucent, and high in luster.  The entire piece measures 9.2 x 6.3 x 4.3 cm.  The main cluster is in good condition with the damage being peripheral from matrix rock attachments.  Excellent quality.  $200








OKN-772     Quartz      Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  A nice, smoky, skeletal crystal with high luster and lots of flash.  11.6 x 8.5 x 4.8 cm.  No damage, flat base, contact on small area of one edge.  Nice piece and price… $225









OKN-773      Fluorite    Pine Canyon, Catron County, New Mexico.  Ex. Harold L. Dibble collection.  A large example of this material measuring 9 x 8.5 x 5.7 cm with crystals to 1.5 cm on edge.  No damage, contacts on edges mostly.  More crystallization on sides and base but main display face holds the nicest crystals.  $200








OKN-774     Quartz      Hot Springs, Arkansas. (I think given some of the surface growth features that it is actually from Brazil).  Ex. Harold L. Dibble collection.  7.5 x 7.4 x 6.3 cm piece that displays nicely, has good clarity, but a couple tiny dings as seen.  Someone will love this piece at this price…. $35







OKN-775     Chalcopyrite with Quartz     Caspalca, Huarochiri, Lima Province, Peru.  Ex. Harold L. Dibble collection.  An attractive example with large crystals of good luster and interesting form.  9 x 6.7 x 4.8 cm.  No damage.  Edge contacts some of which are healed with pyrite crystals growing on them.  $250








Side with minor damage

OKN-776    Aragonite    Morocco.  Ex. Harold L. Dibble collection.  A large single crystal measuring 5 x 2.4 x 2.3 cm.  Floater with only a tiny scraped area on bottom.  Really nice, lustrous example.  $45







OKN-777      Galena and Chalcopyrite    Madan Rhodopi Mountains, Southeast Bulgaria.  Ex. Harold L. Dibble collection.  6.5 x 6.2 x 2.4 cm plate with nice damage free crystals and only moderate edge contacts.  Nice material that for the time has been available at good prices.  $30








OKN-778     Pyrite with Quartz     Leiyang, Hunan Province, China.  Ex. Harold L. Dibble collection.  An aesthetic example for the material from the location… it measures approximately 8.5 x 6.5 x 6 cm.  The only damage is to the big pyrite on the one edge as can be seen.  The views are nice from any direction.  The quartz are all double terminated.  Good luster, great form with the crystal divergence being quite attractive.  Sits upright on its own.  $75








OKN-779     Pyrite     Huangshi, Hubei Province, China.  A fine group with bottom and minor back/side contact.  The cubes are lustrous and well developed with very light striations.  Largest cube has two tiny dings.  Sits and displays very nicely as can be seen.  8.3 x 5.3 x 4.7 cm.  Nice example.  $60








OKN-780     Quartz Faden     Dara Ismael Khann District, Warirstan, Pakistan.  Ex. Harold L. Dibble collection.  An 8 x 3.6 x 3 cm strand of quartz with an obviously well developed faden line.  A very tiny contact from wall rock on one end.  No damage, aesthetic with nice clarity.  $60

Dibble collection.  5.8 x 4.5 x 3.2 cm example with a couple large, blocky, lustrous ferberites.  Lightly striated on their largest faces.  Termination on large crystal is really nicely developed.  No damage except on backside matrix contact.  Stands upright nicely.  $120








OKN-782     Vivianite      Santa Fe, Oruro, Bolivia.  Ex. Harold L. Dibble collection.  7.2 x 3.8 x .9 cm single crystal with fantastic color and great form.  Exceptionally well terminated and nice from every direction.  No damage, no breakdown, no issues.  $300








OKN-783    Quartz with Chlorite Inclusions     Aurina Valley, Trentino, Italy.  Ex. Harold L. Dibble collection.  A single crystal measuring 9.5 x 3.3 x 3 cm.  Minor chipping as seen.  The real attention getter are the fantastic green phantoms!  Backside has a contact area at base and chip.  $190









OKN-784      Barite, Quartz, and Fluorite     Socorro County, New Mexico.  Ex. Harold L. Dibble collection.  I assume this is from the Bingham mine or surrounding area.  The vuggy matrix has several openings with the largest of them holding a nice thin tab of clear barite that measures 2.3 cm on edge.  It is damage free as is the fluorite in that one and other vugs, but surrounding material that was in contact with matrix is incomplete.  A great piece for someone interested in this region and wanting to complete a locality suite.  11.5 x 8 x 5.4 cm.  $175








OKN-785      Grossular      Lake Joco, Mexico.  Ex. Harold L. Dibble collection.  A large pair of intergrown crystals, rather large for the location, for sure, that measure 7.2 x 7.2 x 6.3 cm.  A couple of minor contacts, as seen, but overall in nice condition.  Good luster and great for as one would expect from material from this find.  $95








OKN-786      Hubnerite and Quartz     Pasto Bueno, Peru.  Ex. Harold L. Dibble collection.  An aesthetic miniature that measures 3.8 x 2.3 x 2.3 cm.  Base is flat so it stands on its own.  No damage, edge contact on what I would call the back is even minor.  Fine little example with high luster, nice translucence and excellent balance between the diverging sprats of hubnerite and overgrowing quartz.  Small but really attractive.   $100








OKN-788      Tourmaline on Microcline   Barra de Salinas, Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  8.5 x 7.9 x 4.5 cm Plate of blocky, low luster feldspars with a 1.3 cm tourmaline embedded in one side.  The tourmaline is a greenish blue, gemmy and highly striated (too bad it is small).  No damage.  $85
