Brazil has supplied collectors with wonderful mineral specimens for decades.  The gem material such as tourmaline, aquamarines, and topaz receive most of the acclaim, however there are a great diversity of Brazilian minerals worth noting.  Because we purchase older collections we often have fine examples of Brazilian minerals that are not common in today's contemporary mineral market.

Citrine)     Brazil.  Harold Dibble collection.  The location was not specific on this one but natural citrine is rare so it is likely  Resplendor, Minas Gerais.  This is an attractive point measuring 14.4 x 6 x 4.5 cm.  It is transparent with the majority of its interior being gem quality.  Minor chipping on one edge of termination as seen in second image.   $250

Backside

OKO-536      Quartz, Feldspar, Muscovite      Minas Gerais, Brazil.  Ex. Harold L.

OKM-213

OKM-213    Quartz Faden     Minas Gerais, Brazil.  Ex. Harold L.

OKO-759

OKO-759      Quartz      Minas Gerais, Brazil.    Ex. Harold L. Dibble collection.  A large doubly terminated, smoky crystal dominates this piece.  There are a couple tiny rider crystals as well but, the really odd thing is the matrix.  It is a mix of green and yellow brecciated material.  The yellow actually looks like brazilianite but I am unsure as I have not seen a piece quite like this before.  The specimen measures 12.4 x 8 x 7 cm.  There are no contacts nor damage.  An especially fine specimen.  $650

 

 

 

 

 

 

OKO-757

OKO-757    Quartz      Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  A big parallel growth section of what was probably a huge crystal.  Main body is free of damage (the white areas are simply white colored quartz) and the edges are contacts.  Discoloration of front of big crystal seen in the second image was from a sticker I failed to notice when taking the pictures.  It is now removed.  15.7 x 15.4 x 6 cm.  $150

Dibble.  4.8 x 3 x 1.6 cm specimen with a 2 cm green, transparent to translucent uvite embedded in the side of a clear quartz crystal.  No damage but the back shows regrowth to the uvite so it appears incomplete in side or back view.  Front and other side view beautifully.  The quartz show secondary growth on a couple of faces and some tiny quartz attachments.  A very aesthetic miniature that is mounted on an acrylic base.  Very good example of this older Brazilian material.  $275

OKP-162

OKP-162      Tourmaline on Quartz     Brazil.  Ex. Harold L. Dibble collection.  The tourmaline on this quartz crystal is a nice bluish green color and very  translucent.  The tourmaline measures 11.2 cm and only has one termination (the other is entirely broken off and it is the backside termination that is lower on the specimen) while the entire specimen is approximately 20.5 x 11 x 11 cm.  The quartz is damage free and even the contact and base are healed.  I've made the damage to the tourmaline clearly visible.  Front view is nice but the damage is visible from the back and sides.  Small tourmalines in base of the specimen.  Sits nicely and displays well when positioned as seen in the first image or turned slightly more.  $600

 

 

 

 

 

OKO-762

OKO-762      Quartz (variety Amethyst)      Irai, Rio Grande de Sol, Brazil.  Ex. Harold L. Dibble collection.  This is a fine example of this popular material.  It measures 17.5 x 14 x 3 cm.  It served as the cover specimen on the first draft of Harold's book on quartz.  It is much better in hand with good luster an nice, complete form..  There is no damage and the only contact is on a small part of the flange seen on the lower left in the first image.  A small part of the flange was repaired (so well I can not tell where even with close scrutiny).  The backside is also free of any damage or distractions.  $750

 

 

 

 

 

 

OKO-727

OKO-727     Tourmaline on Quartz     Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  21 x 8.4 x 7.5 cm.  Lots of breakage so I'd consider it rough, at best.  Good green tourmalines to over 7 cm each but, almost all are missing terminations. $130

 

 

 

 

 

 

OKO-728

OKO-728      Quartz and Calcite     Irai, Rio Grande du Sul, Brazil.  Ex. Harold L. Dibble collection.  A purple, pink, green, gray mix of colors compose this large plate of quartz stalactites.  23.5 x 21 x 9 cm.  There are a couple calcites on the backside edge which don't show in any of my photographs.  About a dozen stalactites are incomplete but, this appears to have been done in-situe and I don't think it is damage from human hands.  The best stalactites are well formed and terminated by bulbous clusters of colored quartz.  A fine, showy piece that will display well.  $450

 

 

 

 

 

 

OKO-152

Back

OKO-152    Uvite on Magnesite   Brumado, Bahia, Brazil.  A fine cluster with clear to slightly green, totally transparent, ascicular tourmalines all over these white (often with red inclusions) rhombohedral magnesite crystals.  3.3 x 3.2 x 2.2 cm piece that appears to be a floater.  No apparent damage, views great from any side.  Mounted in a perky box.  Very nice.  $50

 

 

 

 

 

 

 

OKJ-809

Bottom side up

OKJ-809      Aquamarine       Minas Gerais, Brazil.  Ex. Paul and Dawne Dunning collection.  A 1.2 x .7 x .6 cm, partially etched crystal.  Minor yellow glue to be removed.  No damage floater.  $30

Harold Dibble collection.  Fine clear crystals compose this 11.4 x 8 x 7.7 cm cluster.  Healed base and one area with non-healed contact or breakage.  A couple points are completely missing, broke off, but the specimen still displays very well.  $170

 

 

 

 

 

 

OKO-733

OKO-733      Beryl      Criminoso, Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  A large gem crystal of an unusual light green color.  It measures 5.7 x 3.6 x 3.5 cm.  One termination steeply inclined (looks to me like a healed surface vs. an actual set of faces however it also could be an etched termination.  In either case it is complete, natural and damage free.  There is one good side on the piece with the other sides showing chips on the striated prism faces.  One large contact at base of backside of piece.  It certainly has issues but is still a major specimen.  There are at least a couple of hollow tubes running almost the entire length of the crystal.  They are plugged at the termination by a light brown mineralization or clay.  $1,500

 

 

 

 

 

 

OKO-734

OKO-734    Tourmaline on Muscovite      Brazil.     Ex. Harold L. Dibble collection.  This is likely from the Pederneria Mine.  Many multicolored tourmalines to over 6 cm each cover the surface of this plate of muscovite.  The plate is large (16 x 12.4 x 5 cm), and in the shape of a shallow dome.  Crystals are everywhere but most are incomplete or broken.  The majority are blues and pinks, often with pinks having blue rims.  The largest tourmaline is quite nice; however, there is distracting mica overgrowths making it somewhat camouflaged.  $300 takes it.

 

 

 

 

 

 

 

OKO-736

FIGURED SPECIMEN

OKO-736    Quartz     Boca Rica Mine, Galileia, Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 87 by Harold Dibble.  A fine large scepter of smoky quartz.  Lots of skeletal growth on both the cap and stem of the crystal.  It measures 14.5 x 9.4 x 9 cm.  There is some chipping and a little damage to cap in one spot but it is not distracting and on back of piece (even though you can view this piece from any direction nicely).  Well developed clay inclusions... not random, nice layers in between skeletal layers.  Very high luster, even for quartz.  Base is well developed and even more skeletal than the cap.  Very little base contact.  An excellent specimen of aesthetic quartz.   $1,500

 

 

 

 

 

 

OKO-737

FIGURED SPECIMEN

OKO-737      Quartz    Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 18 by Harold Dibble.  It is not hard to figure out why this fine specimen was used in a book on quartz.  It is large, clear, interesting in form, average for luster, but so attractive in-hand that it really gets one's attention.  It measures 16. 5 x 4.4 x 4.1 cm and shows a strong Tessin habit development.  One of its two terminations has a micro rub (Wilber).  Light prism striations on some faces.  A fine piece.  $950

Dibble Collection.  Deep smoky colored, transparent quartz point with no damage and high aesthetic values.  Great luster and form, rich color, gemmy except at base.  Termination has a large rainbow as seen in third image.  $600

Back side with heavy tourmaline encrustation

Base with watermelon tourmalines

Top termination showing green and watermelon tourmalines

OKN-703     Tourmaline with Quartz      Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  One of his finest specimens this huge crystal cluster measures in at an impressive 58 cm long.  It probably weights in at approximately 100 to 150 pounds as I can just barely lift it waist high.  The main quartz crystals are double terminated and heavily encrusted by and included by large green tourmalines to 16.5 cm long and over 3 cm wide each.  The base termination and what I would call the top (top in the first two photos with myself) have very attractive watermelon crystals that are among the largest crystals in the quartz.  The back side is more heavily coated with a thick aggregate of tourmalines of all sizes.  The tourmalines are for the most part transparent with bigger ones being translucent.  The green is quite dark by very clearly GREEN, not black.  It is likely that many more of the crystals are watermelons (having pink cores and green rinds) but unless they are broke it is difficult to tell with casual viewing.  The luster on both the quartz and the tourmalines is excellent.  I just washed the specimen before the photos were taken but the specimen IS DRY, not wet.  The photos are obviously not studio pics and this is all the photographic work I am willing to put into this piece.  It is simply too difficult to move around.

There are plenty of tourmalines that are not terminated but equally as many are.  The terminations are crude to very nice depending on the crystal.  The quartz is in excellent shape with far less damage than would be expected for a specimen of this large a size.  The top and bottom terminations each have a small area with chipping... very minor.  I will not ship this piece so it is for pickup here or at a show I do.  A reasonably close personal delivery could possibly be arranged for a small fee.  A dolly is required to move this specimen and it is very difficult to move floor to floor (but is possible with effort). 

The piece is most suited as a large home decor or museum piece.  When properly lit and backlit it glows!  Fantastic display piece.    $6,000

 

 

 

 

 

 

OKO-732

FIGURED SPECIMEN

OKO-732    Quartz     Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  This is a strange piece described in Harold's book.  It is composed of small stalactites of quartz.  It looks to me like there are thin tabular calcites capping some of the quartz stacks.  VERY strange.  Not very aesthetic so $200 will find it a new home.  19.1 x 12 x 6.1 cm.  No damage.  $200

 

 

 

 

 

 

OKN-976

Scew dislocation

OKN-976     Topaz with Screw Dislocation     Virgem da Lapa, Jequitinhonha Valley, Brazil.  Ex. Harold L. Dibble collection.  This is a pleasing light to medium blue, natural topaz of very high quality.  The really unusual part is it obvious screw dislocation growth feature running its entire length parallel to the "c" axis.  More common in the beryl family of minerals these are quite uncommon in topaz crystals.  This one is only a couple millimeters wide but is much more obvious than my one image indicates.  It can be seen very clearly through the largest of the five non-etched faces.   Take my word on this one..."you can't miss it"! 

The luster on this fine specimen is exceptionally high showing no frosting or abrasion.  It is a damage free floater showing many surfaces etched to different degrees.  Some quite lightly and others heavily leaving behind razor sharp edges.  Internally all gem showing none of the typical veils or internal fracturing.  I only do point and shoot photography for these listings and this is one of those specimens that deserves better.  The crystal views great from any side and sits perfectly for display without a base.  Only one small chip on backside.  It is exquisite in hand and likely the finest specimen from Harold's collection.  7 x 6.6 x 5.5 cm overall.  $8,500

 

 

 

 

 

 

 

OKN-975

OKN-975    Topaz     Virgem da Lapa, Jequitinhonha Valley, Brazil.  Ex. Harold L. Dibble collection.  This is a pleasing medium blue, natural topaz of very high quality.  The luster is exceptionally high showing no frosting or abrasion.  There is one internal but shallow crack on one side that I've tried to show clearly in the fourth image.  Internally very clean for this material... almost all gem.  Great faces visible on all sides less one (the back) which is a mix of contacts that are healed, etched surfaces and a couple small chips near the base of the crystal.  Extremely good condition even on a micro level showing no minor dings, rubs or marks.  Great consistent color with no distractions from its high aesthetics.  The base is cleaved so the specimen sits great without any base.  Only one small chip on backside.  8.2 x 6.5 x 5 cm overall.  $5,500

 

 

 

 

 

 

 

OKN-327

Bottom

OKN-327     Quartz      Minas Gerais Brazil.  Ex. Harold L. Dibble collection.  This floater totally complete with beautiful, clear point to 6.4 cm each.  The piece measures 8.4 x 6.5 x 5.3 cm overall.  Base is somewhat flat so it sits great.  The highest of lusters, aesthetic form, and fantastic quality.  One tip ding that needs magnification to find.  $300

 

 

 

 

 

 

OKN-127

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

Back?

OKM-824      Quartz    Brazil.   Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 75 By Harold Dibble.  This large cluster at first glance has an Arkansas look to it... lots of tabular, double terminated, clear to milky crystals compose this large, 16 x 11 x 8 cm cluster.  The damage is minor with two spots on the front showing crystal breakage and back and a few more.  Overall in nice condition as Harold's book and the images show.  High luster well formed crystals without distracting qualities such as staining, contacts, etc.  $700

 

 

 

 

 

 

 

 

OKM-822

Back

OKM-822     Quartz       Brazil.    Ex. Harold L. Dibble collection.  A large plate measuring 22 x 17 x 5.3 cm.  Smoky tips on parallel growth (actually one crystal or a healed shard off of one huge crystal) with gemmy interiors to upper half of specimen and more included interior to lower half of specimen.  Very nice displayable example of high luster.  Only the very tiniest of tip dig on last termination.  Upper regions are the quality of fine alpine quarts like that from Switzerland.  Really nice piece for a Brazilian specimen.  $550

 

 

 

 

 

 

OKM-809

This seems to be the best (most accurate) color representation

OKM-809    Topaz     Virgem da Lapa, Jequitinhonha Valley, Brazil.  Ex. Harold L. Dibble collection.  This is a beautiful rich blue (images appear more washed out and lighter than the actual piece, also there are no green overtones, it is a true rich blue) natural topaz of very high quality.  The luster is exceptionally high showing no frosting or abrasion.  The accessory species is lepidolite and is sparse providing an attractive and not distracting highlight to this gemmy crystal.  Internally very clean for this material with no serious fracturing.  Views through to an etched backside that has some large smooth chipped regions that blend nicely with the etched regions.  One end is chipped and other fully terminated.  13.1 x 6.1 x 5 cm overall.  I've shown plenty of photos so you can determine if the backside damage distracts you.  I do not think it is distracting.  I feel it is a high quality example of rare to find material.  $7,500
