Assorted Bolivian Mineral Specimens from Classic and Contemporary Localities

10 Pages of excellent and affordable mineral specimens from Bolivia.  A great mix of rare, classic, unusual, well known and hard-to-find pieces that represent more modern discoveries and historic finds dating back decades.  There are a few pieces from my personal collection, as well as my parents' collections.  I've been putting together this update for a few years, continually adding good Bolivian pieces here and there, (from recent mining activity, dealers stock and private collections) and the end result was this huge update.  Even with the number of pieces listed, we still have plenty more to offer, so stay tuned !

Copper (leaf-like specimen) from Corocoro District, Pacajes Province, La Paz Department, Bolivia [./bolivia711/bol711b01a.JPG] Copper (leaf-like specimen) from Corocoro District, Pacajes Province, La Paz Department, Bolivia [./bolivia711/bol711b01b.JPG] Copper (leaf-like specimen) from Corocoro District, Pacajes Province, La Paz Department, Bolivia [./bolivia711/bol711b01c.JPG] Copper (leaf-like specimen) from Corocoro District, Pacajes Province, La Paz Department, Bolivia [./bolivia711/bol711b01d.JPG]

Copper (leaf-like specimen)

Locality: Corocoro District, Pacajes Province, La Paz Department, Bolivia

Specimen Size: 7.7 x 6.9 x 1.2 cm (small cabinet)


A very attractive “locality” specimen, and a surprise discovery from early 2011. These are the first Copper “sheets” that I have seen from Corocoro, and according to the locals, there were very few found. Most people are familiar with the Copper pseudomorphs after Aragonite from this locality, but to find non-pseudomorphic, native Copper is rather rare in my experience. This aesthetic, branching, "sheet" of Copper is a great display specimen from this historic locality. It truly resembles some kind of organic plant life, i.e., a leaf or even a scallop shell! Very unusual, and certainly out of the ordinary for Copper in general. Good Bolivian Coppers are not common on the market, and I was told that the locality was recently purchased by a Korean mining company, so collecting and obtaining specimens will become very difficult in the future.

Copper (leaf-like specimen)

This aesthetic, branching, "sheet" of Copper is a great display specimen from this historic locality. On the micro level the piece shows very unusual "wormholes" that gives the piece an amazingly organic appearance. It truly resembles some kind of plant life, i.e., a group of leaves or even a group of fire coral! Very unusual, and certainly out of the ordinary for Copper in general.

Copper with Chrysocolla, Cuprite and Gypsum

Locality: Corocoro District, Pacajes Province, La Paz Department, Bolivia

Specimen Size: 15.3 x 10.1 x 2.3 cm (large cabinet)


Most people are familiar with the Copper pseudomorphs after Aragonite from this locality, but to find non-pseudomorphic, crystallized native Copper is rather rare. This aesthetic, very good sized, branching, "sheet" of crystallized Copper is a great display specimen, not to mention a worthwhile association specimen from this historic locality. It has some of the most well-defined dodecahedral, tetrahexahedral and octahedral crystals I have seen from the locality. On the micro level (see photos) one can see blue-green Chrysocolla and metallic reddish Cuprite with some white Gypsum. These pieces started to trickle out around October of 2009 and this piece is arguably the best sample of this material that I have handled for aesthetics, quality, size and displayability. I actually held this piece back when I first obtained the lot as it was the best one at the time, and I hoped more would show up, but now two years later I haven’t seen another one as impressive. Good Bolivian Coppers are not common on the market, and I'm told that the locality was recently purchased by a Korean mining company, so collecting and obtaining specimens will become very difficult in the future.

Copper

Locality: Corocoro District, Pacajes Province, La Paz Department, Bolivia

Specimen Size: 6.1 x 4.3 x 0.7 cm (small cabinet)


A very attractive “locality” specimen from Corocoro which was collected in October of 2010. Most people are familiar with the Copper pseudomorphs after Aragonite from this locality, but to find non-pseudomorphic native Copper is rather rare. This beautiful, aesthetic, branching, arborescent group of crudely crystallized Copper is a great display from this historic locality. For the size and aesthetic, and this piece is one of the better samples of this particular material that I have handled. Keep in mind that the majority of the Copper from Corocoro is not crystallized whatsoever, so this one is certainly worthwhile for a collector of Bolivian minerals, or native elements. Good Bolivian Coppers are not common on the market, and I'm told that the locality was recently purchased by a Korean mining company, so collecting and obtaining specimens will become very difficult in the future.

Phosphophyllite (classic textbook twins) with Siderite and Sphalerite

Locality: Unificada mine, Cerro Rico, Potosi, Potosi Department, Bolivia

Specimen Size: 3.1 x 2.2 x 1.6 cm (thumbnail)
Largest Crystal: 2 mm


Phosphophyllite is one of the most rare and beautiful species in the mineral world, and arguably, one of the most desirable phosphate species extant. It is not only highly sought after, but in recent years has been dubbed the "Holy Grail" of mineral species for collectors. Many collectors and dealers alike treasure this species for its immense scarcity and immeasurable combination of form and color. There are only a few localities in the world in which fine quality crystals of Phosphophyllite occur. The type locality is in Hagendorf, Germany, where the crystals rarely exceeded 6 mm in length. Over 50 years ago a second, and much more significant discovery was made in Potosi, Bolivia. This find produced some of the most spectacular, intense blue-green color, "butterfly"-twinned crystals up to 15 cm on matrix !! These days, the Bolivian specimens are considered great "classics", and outstanding specimens are few and far between. Though matrix specimens of Phosphophyllite do exist, they are very seldom seen in today's market. This specimen is a "classic", exceptionally rare, gemmy, incredibly beautiful specimen of the great phosphate featuring several small, very sharp, incredibly well-formed, gemmy, alluring, blue-green color “butterfly”-twinned crystals with tan Siderite and dark reddish-brown Sphalerite. I photographed the Phosphos under the microscope to better show their quality. These are stunning textbook twins of Phosphophyllite, and despite their smaller size, I still consider this to be a collector quality specimen. Please note that specimens Phosphophyllite simply are NOT seen in today's market, in ANY format !! Any mineral collector will tell you that a specimen Phosphophyllite is a great rarity and should be treasured not only for its scarcity and beauty, but sheer value on the market. It is hard for me to convey the difficulty that many collectors experience in the search for this mineral. This is the last good specimen from Unificada that I have to offer, and with so little coming out now, be sure to pick this one up, as I don’t know if more will be available in the future.

Phosphophyllite (classic “butterfly” twins)

Locality: Huayllani mine, Infiernillos mine, Huayllani, Machacamarca District, Saavedra Province, Potosi Department, Bolivia (new locality for Phosphophyllite in Bolivia)

Specimen Size: 3.3 x 2.1 x 1.7 cm (miniature)
Largest Crystal: 2.3 cm


This specimen is from the recent finds in the Machacamarca mining district in Bolivia. It is not from the typical Bolivian locality at the Unificada mine in Potosi. Phosphophyllite is one of the most rare and beautiful species in the mineral world, and arguably, the one most desirable phosphate species extant. It is not only highly sought after, but in recent years has been dubbed the "Holy Grail" of mineral species for collectors. Many collectors and dealers alike treasure this species for its immense scarcity and immeasurable combination of form and color. There are only a few localities in the world in which fine quality crystals of Phosphophyllite occur. The type locality is in Hagendorf, Germany, where the crystals rarely exceeded 6 mm in length. Over 50 years ago a second, and much more significant discovery was made in Potosi, Bolivia. This find produced some of the most spectacular, intense blue-green color, "butterfly"-twinned crystals up to 15 cm on matrix !! A little over a year ago, a second important locality for Phosphophyllite was discovered in Bolivia, and it did a great deal to bolster the number of Phosphophyllites on the market. This particular piece features dozens of exceptionally rare, fairly sharp, translucent, green color (partially iron-coated), euhedral crystals with classic "butterfly"-twins. The twins on this specimen are some of the largest I’ve seen from the locality, and this particular piece was one that I held back when I first purchased these specimens in anticipation that more were on the way. Sadly, very little followed, so I decided to take out this beauty and put it up for sale. It goes without saying that specimens of Phosphophyllite with crystals this size can be exceptionally pricey in some cases. We have all seen pieces in the past offered for many, many thousands of dollars, although this piece is not of the same calibre. It is however a good quality display specimen from a very exciting new find, which hopefully could one day produce specimens of the same size and quality as those from Unificada ! Please note that specimens of Phosphophyllite simply are NOT seen in today's market, in ANY format. Do not miss out on this piece as few seem to have been found, and very little is coming out if any at all right now.

No. BOL711B11 - $ 950.00

Hopeite (!!) (first known specimens from South America!) with Phosphophyllite

Locality: Huayllani mine, Infiernillos mine, Huayllani, Machacamarca District, Saavedra Province, Potosi Department, Bolivia

Specimen Size: 5.2 x 3.7 x 1.8 cm (small cabinet)
Largest Crystal: 5 mm


One of the most exciting and yet incredibly limited discoveries for Bolivian minerals. Bolivia is well-known for its phosphate minerals, but Hopeite (despite its fairly simple chemistry) has never been reported. This is not only a first-time find for Hopeite from Bolivia, but to the best of my knowledge, these specimens are the first ever Hopeites from South America! I acquired just a few of these specimens when I purchased the Phosphophyllites from this locality, and I honestly thought them to be a fairly common and unassuming associated species i.e., Barite. To the credit of Alfredo Petrov and Dr. Tony Kampf at the L. A. County Museum, they were able to verify that these specimens were indeed Hopeite! Hopeite is truly only known from a few world localities in fine crystallized specimens, the most famous being the Kabwe Mine (Broken Hill Mine) in Zambia. The pieces from Bolivia are reminiscent of the classic and highly sought after Zambian specimens, showing the same “tooth” like habit. As a matter of fact, when I acquired these specimens, the miner in Bolivia who found the specimens was referring to them as “dientes” (Spanish for teeth). This piece is filled with dozens of translucent, white to off-white color Hopeite crystals which vary in habit from slender “blades” to incredibly well-formed blocky orthorhombic crystals. If the immense rarity of a Bolivian Hopeite was not enough, this piece is associated with the incredibly rare, and highly desirable phosphate species, Phosphophyllite, which many collectors and dealers have dubbed the “Holy Grail” of minerals! The contrast of the satiny white Hopeite with the light blue-green Phosphophyllite sitting on the reddish-brown altered Sandstone matrix makes for an eye-catching specimen. Without question, these specimens stand as one of the greatest rarities that I have handled from Bolivia, and would make a superb addition to any rare mineral suite. This specimen was collected in late 2010, and to the best of my knowledge, no more have been found.

Hopeite (!!) (first known specimens from South America!) with Phosphophyllite

Locality: Huayllani mine, Infiernillos mine, Huayllani, Machacamarca District, Saavedra Province, Potosi Department, Bolivia

Specimen Size: 3.7 x 2.3 x 2.2 cm (miniature)
Largest Crystal: 4 mm


One of the most exciting and yet incredibly limited discoveries for Bolivian minerals. Bolivia is well-known for its phosphate minerals, but Hopeite (despite its fairly simple chemistry) has never been reported. This is not only a first-time find for Hopeite from Bolivia, but to the best of my knowledge, these specimens are the first ever Hopeites from South America! I acquired just a few of these specimens when I purchased the Phosphophyllites from this locality, and I honestly thought them to be a fairly common and unassuming associated species i.e., Barite. To the credit of Alfredo Petrov and Dr. Tony Kampf at the L. A. County Museum, they were able to verify that these specimens were indeed Hopeite!

Franckeite on matrix (!)

Locality: Siglo XX Mine (Siglo Veinte Mine), Llallagua, Bustillo Province, Potosi Department, Bolivia

Specimen Size: 7.0 x 4.2 x 3.3 cm (small cabinet)
Largest Crystal: 1.1 cm


Franckeite is a relatively rare iron, lead, tin, antimony sulfosalt, which is not often found in well-crystallized display specimens, especially on matrix! This is one of the very few specimens of Franckeite that I have seen from the famous Siglo XX mine, and certainly one of the most eye-catching. The piece hosts several groups of Franckeite consisting of somewhat "sword"-shaped crystals forming spherical aggregates which are sitting on minor iridescent Sphalerite and/or Wurtzite with minor associated Pyrite and Quartz on matrix. A great quality specimen for somebody looking to own a rare and attractive "black" mineral. This is also a good opportunity to acquire something that is rarely offered in the open market, especially on such attractive matrix! This species belongs to the only group of minerals that forms in naturally "round" or "cylindrical" shaped crystals. This specimen was collected in August of 2010, and is excellent for the material. There were only a handful of good specimens, and well crystallized pieces ON MATRIX like this are few and far between from any locality. A wonderful rare species from one of the most classic mines in Bolivia!

Childrenite

Locality: Siglo XX Mine (Siglo Veinte Mine), Llallagua, Bustillo Province, Potosi Department, Bolivia

Specimen Size: 2.3 x 2.0 x 1.7 cm (thumbnail)
Largest “Sphere”: 4 mm


Some of the best crystallized phosphates from Bolivia are found at this locality. Childrenite is a relatively rare hydrated, iron aluminum phosphate and some of the better and more unique specimens of this mineral come from Llallagua. There are only a few localities in the world where this mineral is found. This specimen features several excellent, rare, semi-lustrous, brownish color, intergrown spherical aggregates (comprised of dozens of triangular bladed crystals) of Childrenite. I have photographed the crystals under the microscope to better illustrate their quality. This is unique material, and this is one of the ONLY pieces that I have to offer. A rare display specimen of this great phosphate from this amazing locality. Don't miss out on this one.

I have photographed the crystals under the microscope to better illustrate their quality. The fact that the spheres are somewhat isolated and not completely intergrown makes for an impressive and rarely seen representation from Siglo XX. Certainly one of the VERY few matrix Childrenite specimens that I have offered where one can see beautifully crystallized spheres with the naked eye. This is unique material, and this is one of the best and ONLY pieces that I have to offer. A rare display specimen of this wonderful phosphate from this amazing locality.

Bournonite on Siderite

Locality: Viboras Mine, Machacamarca, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 9.8 x 6.5 x 4.5 cm (cabinet)
Largest Crystal: 2.7 cm


Matrix specimens of Bournonite from Machacamarca are hard to find, especially in the small cabinet to cabinet size range. Crude mining methods combined with brittle nature of the Bournonites (and sometimes their host rock) do not allow many crystals to leave the mine on matrix. This piece features several very well defined, metallic, steel-grey color, sharp, semi-lustrous tabular crystals of Bournonite on iron-stained rhombic Siderite matrix. For the size, aesthetics and quality of the piece, it is certainly one of the better specimens in this size range that I have had to offer in years. Virtually no damage to the Bournonites.

This piece was collected in August of 2009, and is one of the few matrix Bournonites in this update. An eye-catching small cabinet specimen hosting a sharp, lustrous, silvery bladed crystal of metallic Bournonite on iron-stained micro-crystallized Quartz. It is a small miracle that the piece was not completely destroyed in the blast when it was found, let alone the fact that the crystal stayed on matrix!

I have to say up front that this piece simply is better than the photos indicate. The HIGH luster of the faces made it difficult to photograph. The specimen is in great shape overall, and the robust crystals with their sharp, well-defined surfaces are very hard to find from this mine. The piece is twinned and shows the classic "cogwheel" shape that was made famous by the classic specimens from Cornwall, England.

ex.  Brian Kosnar


A really interesting and certainly unique display specimen of  Bournonite from this famous locality. This piece is unlike anything I have offered from Machacamarca, as it features wonderful, sharp, lustrous, layered, tabular, gun metal grey color crystals which are sitting atop lustrous, striated black crystals of Sphalerite with minor greenish-brown Siderite. A great association specimen of this well-known material, and we really went crazy with the photos on this one because it has so much going on. With so many average quality Chinese Bournonites on the market, these Bolivian pieces might get lost in the mix, but when they're good, they are very impressive. This piece was found in early 2009, and was actually part of my personal collection for a time.

Bournonite (“cogwheel”) on matrix

Locality: Viboras Mine, Machacamarca, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 9.1 x 4.7 x 3.8 cm (small cabinet)
“Cogwheel” Group: 3.1 x 2.8 cm


To find a fine quality "cogwheel" such as this on matrix from Machacamarca is not common, and the photos honestly do not do this piece justice as it is much more eye-catching in person. This piece features a few attractive "cogwheel"-twinned crystal groups of Bournonite with superb luster sitting atop a matrix of micro Pyrite, Quartz and Sphalerite. The "cogwheels" feature dozens of discreet, striated "cogs" that form the edge of the fairly thick metallic grey crystals. One side of the crystal is contacted where it more than likely was removed from the host rock, but the piece in general is in very good shape.

Bournonite (“cogwheels”)

Locality: Viboras Mine, Machacamarca, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 3.7 x 2.0 x 1.2 cm (miniature)


A hard to find "cogwheel" group of sharp, thick, blocky modified twinned crystals of Bournonite with excellent metallic luster. The piece displays well from a few angles. The stacked appearance of the crystals, combined with the bright luster makes this one of the more eye-catching smaller Bournonites in this update. With so many average quality Chinese Bournonites on the market, these Bolivian pieces might get lost in the mix, but when they're good, they are very impressive.

Bournonite on Quartz

Locality: Viboras Mine, Machacamarca, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 2.9 x 1.6 x 1.5 cm (thumbnail)
Bournonite Crystal: 1.3 cm


This piece was collected in August of 2009, and is one of the few matrix Bournonites in this update. An eye-catching specimen hosting a sharp, lustrous, silvery bladed crystal of metallic Bournonite on iron-stained micro-crystallized Quartz. It is a small miracle that the piece was not completely destroyed in the blast when it was found, let alone the fact that the crystal stayed on matrix!

Bournonite

Locality: Viboras Mine, Machacamarca, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 3.4 x 2.5 x 0.4 cm (miniature)


A wonderful single crystal of Bournonite showing BRIGHT metallic luster, and superb form. Crystals with high luster from this mine are not common, even in toenail/small miniature sized crystals like this one. The piece is complete all the way around and damage free, save the base where it came off the host rock. It certainly could be classified as a “cogwheel” piece, as it is twinned, and does have some small “cogs” around the edges.

Bournonite

Locality: Viboras Mine, Machacamarca, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 3.1 x 3.0 x 1.9 cm (thumbnail)


A pair of very well-formed, sharp, semi-lustrous, soft metallic grey colored tabular blades of Bournonite are intergrown to create this eye-catching little display specimen. The crystals are virtually damage free, save for a very small contact on one edge. For an added touch, the crystals are associated with micro grey Quartz. Great quality and rather aesthetic for the material. From a find in June of 2007.

Bournonite (“cogwheel”-esque twins)

Locality: Viboras Mine, Machacamarca, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 2.9 x 2.2 x 1.9 cm (thumbnail)


A hard to find "cogwheel"-esque group of sharp, fairly thick, blocky modified twinned crystals of Bournonite with excellent luster and aesthetics. The piece would be classified as a large thumbnail / small toenail, and displays well from several angles (my favorite being the last picture). The stacked appearance of the crystals, combined with the bright metallic luster makes this one of the more unique smaller Bournonites I have handled from this mine. Excellent condition on the display side.

Specimen Size: 2.5 x 2.0 x 1.6 cm (thumbnail)


An attractive little Bournonite group hosting a pair of intergrown, sharp, semi-lustrous, metallic grey color bladed crystals. Overall, the quality is certainly better than most from this mine, and it’s essentially damage free save the bottom where it detached from the matrix.

“Cogwheel”: 2.3 x 2.0 cm


ex.  Brian Kosnar


Without question, this is one of the finest matrix “cogwheel” Bournonites that I have handled/owned and offered for sale. I honestly don’t keep much from Bolivia for my personal collection, and I almost never keep the best piece from any lot, but this one was really special, so much so that I had to hold on to it for a little while. It remains as one my favorite Bolivian Bournonites that I’ve seen. I have to say up front that the piece is rather difficult to photograph, and it’s simply BETTER IN PERSON. A very good quality, COMPLETE, sharp, lustrous, silvery colored classic “cogwheel”-twinned crystal group is aesthetically flaring off lustrous, golden, octahedral metallic Pyrite matrix. The “cogwheel” is essentially undamaged, save the tiniest of “Wilbers” on the edge. It’s amazing to me that you can see all sides of the “cogwheel” as it’s not buried into the Pyrite matrix, which is EXCEPTIONALLY RARE in my experience with the material. If you’re a Bolivian collector, or a collector of fine quality sulfides/sulfosalt display specimens, then you cannot afford to pass this one up. The piece is priced accordingly for the superb quality, rarity and the fact that it is literally one in several thousand. I cannot recall a comparable Bournonite from Machacamarca, and I can say without fear of contradiction, that this piece is truly one-of-a-kind.
