Ferberite with Quartz

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

Specimen Size: 9.7 x 8.2 x 5.3 cm (cabinet)
Largest Ferberite: 7.8 cm


Unquestionably, this is the finest matrix Ferberite specimen that I have handled from this most classic of Bolivian localities. Siglo XX is probably best known for its phosphate species, and good Ferberites are a great rarity, especially such well-crystallized examples on matrix like this one! For years, I had only seen a scattered few Ferberites from this mine in photos, and in 2008, I acquired a very small batch of specimens from a miner who found them in a remote section of the mine. Sadly, no more were found, and I held these pieces in the hopes that more would come so I could post a bigger update. I’m fairly certain at this point that we may not see these specific Ferberites from Siglo XX again. This specimen hosts a predominant, sharp, large (for the locality), very well-formed, lustrous, jet-black, blocky crystal with a few accenting Ferberites which are associated with amazingly gemmy, very sharp, lustrous prisms of nearly colorless Quartz crystals! Ferberite is probably best known from other Bolivian localities such as Tasna, and I can’t remember a single specimen from Tasna with such attractive Quartz crystals as those seen on this specimen, which is remarkably NOT from Tasna!! On the display side, the piece is in great shape, despite some roughness around the edges. This is much more than a Bolivian Ferberite, as its aesthetic quality elevates it to give a broader appeal to a worldwide collector. For the size and visceral beauty, this is not just a “black” rock. It’s a great display specimen, the likes of which I have never seen from the renowned Siglo XX mine. If you’re a Bolivian collector, I have to believe you don’t have a matrix Ferberite as fine as this one.

Ferberite

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 15.8 x 10.8 x 5.4 cm (large cabinet)
Largest Crystal: 3.0 cm


A gorgeous full cabinet display specimen of Ferberite featuring dozens of incredibly sharp and well-formed, “wedge”-like blades with great luster and a stark jet-black color. There are even a few twinned crystals which are somewhat buried, but can be seen upon close inspection. Pieces this size from Tasna are not common for a few reasons. The material is so heavy that it often splits apart under its own weight in the blast underground during the mining process. Secondly, since Ferberite is somewhat brittle, the crystals tend to cleave fairly easily, which often leads to specimen that are riddled with damage. Lastly, the miners do not take the greatest care to preserve specimens after they’ve been collected, and will often throw them into a sack unprotected where they bash into one another, often ruining perfectly good pieces. This particular piece is in great condition for the size, as the majority of the crystals are completely undamaged. A small miracle to be sure to have such an eye-catching Ferberite from Tasna in this size. Accenting Arsenopyrite and Marcasite make for a gentle contrast throughout specimen. Hard to photograph and BETTER in PERSON.

Ferberite (twin)

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 3.3 x 2.4 x 2.3 cm (miniature)


A classic “V”-shaped twin (twinned along the {100} face) of Ferberite from the famous Tasna mine in far southern Bolivia. This locality has produced what have to be the finest twinned Ferberite crystals extant. Ferberite as a species is not known in well-crystallized examples worldwide, and the twins from Tasna are a favorite among collectors. This twin is a great example of this material as it shows a fairly “open” twin, with aesthetic form. Along with the amazingly sharp faces, good luster and minimal damage, it’s a very worthwhile representation of these classic specimens.

Ferberite (rare doubly-terminated twin) on matrix!

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 8.7 x 4.4 x 4.2 cm (small cabinet)
Ferberite Twin: 2.5 cm


A VERY rarely seen Ferberite twin on matrix from Tasna. Often, the Ferberites from Tasna are not found on matrix as they are heavy in nature and brittleness of the species causes it to fall off the host rock in the blast during mining operations. This specimen is not only an impressive, and dramatically aesthetic matrix piece, but the Ferberite twin is DOUBLY-TERMINATED, which is only seen in a very small percentage of pieces from Tasna. I acquired this piece in early 2009, and when it arrived, it was completely filthy. I honestly believe that the layer of oxidation and dirt that covered the piece actually helped to preserve the quality of the twin, as it’s amazingly sharp, lustrous, smooth and incredibly well-formed. Only a small corner of the twin has a “rub” which keeps it from being completely perfect, but it’s more than forgivable considering that virtually every Ferberite from Tasna has some kind of imperfection. A few accenting blades of Ferberite and nearly micro Quartz crystals sit on the matrix to create this beautiful and three-dimensional display specimen. The quality is superb, and the piece truly looks better in person as Ferberite is a difficult species to accurately photograph. A more than worthwhile matrix Ferberite that would make a great addition to any collection.

Ferberite (twin)

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 2.9 x 2.6 x 1.2 cm (thumbnail)


A classic “V”-shaped twin (twinned along the {100} face) of Ferberite from the famous Tasna mine in far southern Bolivia. This locality has produced what have to be the finest twinned Ferberite crystals extant. Ferberite as a species is not known in well-crystallized examples worldwide, and the twins from Tasna are a favorite among collectors.

Along with the fairly sharp faces and matte luster, it’s a worthwhile representation of these classic specimens. The piece is contacted on the bottom, but still displays well as you can see from the photos.

Ferberite with Quartz

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

Specimen Size: 2.5 x 1.7 x 1.5 cm (thumbnail)


A very rarely seen Ferberite specimen from the famous Siglo XX mine in Bolivia. This attractive large thumbnail features one predominant and very sharp, well-formed blocky crystal of jet-black Ferberite with a few accenting blades of Ferberite and minor associated gem Quartz crystals on a small amount of matrix. Very good quality not only for the locality, but the species in general. Hard to photograph and better in person. If you’re a Bolivian collector, you know how difficult it is to obtain any Ferberite specimens from Llallagua, and this little piece should not be overlooked as it is much better quality than a reference specimen, and would make a great addition to any Bolivian suite.

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

Specimen Size: 11.0 x 8.8 x 3.7 cm (cabinet)
Largest Crystal: 3.7 cm


One of the best Ferberite specimens from the famous Siglo XX mine in Bolivia that I have offered. This attractive cabinet sized specimen features a few very sharp, well-formed blocky and bladed crystals of jet-black Ferberite sitting atop sharp, lustrous, gemmy, off-white colored Quartz crystals on matrix. Very good quality not only for the locality, but the species in general. Hard to photograph and better in person. If you’re a Bolivian collector, you know how difficult it is to obtain any Ferberite specimens from Llallagua, and this piece should not be overlooked as it is much better quality than a reference specimen, and would make a great addition to any Bolivian or worldwide suite. Very minimal damage and superb for the material, especially from this mine.

Ferberite (multi-twinned specimen!)

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 7.4 x 5.7 x 5.3 cm (small cabinet)


This is certainly one of the most impressive twinned Ferberites that I have seen. Rarely does one encounter single well-formed twins from Tasna, let alone a group like this! The piece is highly aesthetic and sculptural as it comprises several sharp, well-formed, black, tabular twinned blades (twinned on the {100} face) creating a rarely seen MULTI-twinned group. There are four distinct twins which are intergrown to form a very three-dimensional display specimen. This piece is complete on both the top and bottom, and is not cleaved, which is remarkable for a Ferberite of this size with so much weight. A small nick can be seen near the bottom, but when the piece is viewed head on, it’s not very noticeable. If the piece were 100% perfect, I would have it priced much higher as it is such a large and amazingly aesthetic overall specimen. This locality has produced what have to be the finest twinned Ferberite crystals extant, and this remarkable hand sized piece is definitely one of the best around for what it is. The Bolivian Ferberites (especially those from Tasna) are often and sadly underrated/overlooked, but in many instances will surpass other Ferberites from Yaogangxian or Panasqueira for size and quality.

Ferberite (multi-twinned specimen!)

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 4.4 x 3.2 x 2.8 cm (miniature)


This was one of the very few multi-twinned pieces from the recent find of these amazing specimens (June of 2010). This species was sometimes previously referred to as "Wolframite", which was supposed to be an intermediary species between Ferberite and Hubnerite, but has since been discredited. This eloquent piece features a few sharp, highly lustrous, jet black blades of Ferberite which are twinned along the a{100} face. It is not a simple twin consisting of two blades, but rather a few blades in parallel growth twinned together. The piece has a small contact towards one of the corners, but considering that the large majority of Ferbs from Tasna have serious damage problems, this one is in great shape, and displays well from a few angles. The luster is better than the majority of the Ferberites from this mine, and the piece is complete on both the top and bottom, and is not cleaved, which is impressive as most of the Ferberite twins are broken on one end. Bolivian Ferberites (especially those from Tasna) are often and sadly underrated/overlooked, but in many instances will surpass other Ferberites from Yaogangxian or Panasqueira for size and quality. BETTER in person, and difficult to photograph, but as is the case with the majority of Ferberites from Tasna, they don’t like the camera, and take my word for it, this is a good for the size and the fact that it’s a multi-twinned specimen.

Ferberite (twin)

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 4.6 x 4.2 x 3.8 cm (miniature)


A fantastic and hefty twinned Ferberite specimen from the famous Tasna mine in Bolivia. This mine is probably best known for its Ferberites, and it’s because of twins like this. As a species, Ferberite is rarely found in twinned crystals, most often as blades. This impressive and attractive twin has wonderful blocky form with very sharp faces, excellent luster, great form and very little in the way of damage. It’s incomplete on the back where it came off the matrix, and one corner of the twin has a slight “rub”, which I consider to be trivial, as virtually every Ferberite twin from Tasna has some kind of damage. Bolivian Ferberites (especially those from Tasna) are often and sadly underrated/overlooked, but in many instances will surpass other Ferberites from Yaogangxian or Panasqueira for size and quality.

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 4.2 x 3.3 x 2.2 cm (miniature)


One of the most attractive miniature sized specimens of twinned Ferberite from Tasna that I have offered. The piece features not one, but two eye-catching twins of Ferberite which are aesthetically intergrown to create a lovely display specimen. An associated gem quality Quartz crystal on the base of the specimen is a great touch. A very small nick on the top of the piece is the only spot of damage that I can see on the display side (the piece is incomplete on the back where it detached from the pocket wall). It’s rare to find a pair of intergrown twins like this from Tasna, especially with sharp faces, great and form and in such good condition! This is more than just a “black” rock just based upon its visceral beauty. Very showy and desirable for the species!

Ferberite

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 16.3 x 9.7 x 7.8 cm (large cabinet)
Largest Crystal: 7.7 cm


A remarkable large cabinet display specimen of Ferberite from the classic Tasna mine in southern Bolivia. It is not common to find pieces of this size with such great crystallization and quality! Many sharp, rather lustrous, well-formed, jet-black, stepped bladed crystals of Ferberite are aesthetically sitting on massive Arsenopyrite matrix. For the most part, the piece is in great condition, with a few minor blemishes here and there, which truly do not detract from the overall appeal and sheer visual impact of this impressive specimen. One of the larger blades in the center of the piece is actually doubly-terminated, and countless more are so eye-catching, that you have to marvel at a specimen of this stature. I have to stress that because the piece has such a great three-dimensional quality, and the fact that the crystals have good luster, it was a difficult specimen to photograph, and is better in person. If you like large display specimens, and you’re looking to expand your collection with a top-notch Ferberite, this is the one for you.

Ferberite

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 3.6 x 3.3 x 2.8 cm (miniature)


A predominant, sharp, lustrous, fairly thick blade of Ferberite is surrounded by several smaller blades and one little “closed” twin of equal quality. The main crystal is contacted on the side, hence the reduced price, but it’s still a good reference specimen from this famous Ferberite producing locality.

Ferberite (twin)

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 3.1 x 2.1 x 2.0 cm (thumbnail)


A classic “V”-shaped or “heart”-shaped twin (twinned along the {100} face) of Ferberite from the famous Tasna mine in far southern Bolivia. This locality has produced what have to be the finest twinned Ferberite crystals extant. Ferberite as a species is not known in well-crystallized examples worldwide, and the twins from Tasna are a favorite among collectors. This twin is a great example of this material as it shows a fairly “open” twin, with aesthetic form. Along with the amazingly sharp faces, good luster and minimal damage, it’s a very worthwhile representation of these classic specimens.

Ferberite (multi-twinned specimen!)

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 8.2 x 3.6 x 3.6 cm (small cabinet)


This was one of the very few multi-twinned pieces from the recent find of these amazing specimens (June of 2010). This species was sometimes previously referred to as "Wolframite", which was supposed to be an intermediary species between Ferberite and Hubnerite, but has since been discredited. This eloquent piece features sharp, highly lustrous, jet black blades of Ferberite which are twinned along the a{100} face. It is not a simple twinned specimen, as it hosts THREE individual twins which are beautifully intergrown. The piece has a “rub” towards one of the corners, but considering that the large majority of Ferberites from Tasna have serious damage problems, this one is in great shape (especially for the size). The luster is better than the majority of the Ferberites from this mine. Like many Ferberites, the piece looks better in person, especially when you can hold it in your hands and rotate it in the light to see all three twins. Bolivian Ferberites (especially those from Tasna) are often and sadly underrated/overlooked, but in many instances will surpass other Ferberites from Yaogangxian or Panasqueira for size and quality. For the size, quality, and the fact that there are THREE DISTINCT TWINS together, this is a special piece.

Ferberite

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 7.3 x 6.4 x 4.6 cm (small cabinet)
Largest Crystal: 6.2 cm


A beautiful bladed group of Ferberite from the famous Tasna mine. The crystallization is excellent for the species and the locality. Many sharp, highly lustrous, very well-formed, jet-black blades (some of which are doubly-terminated) and two small “closed” twins of Ferberite are intergrown to create this eye-catching and impressive hand-sized specimen. A minor amount of Arsenopyrite and Marcasite can be seen on one side of the specimen. Despite a little bit of rough edges around the periphery, the piece is in amazingly good shape. BETTER in person, and difficult to photograph, but it would certainly make a worthwhile addition to any collection. Blades of Ferberite this size and with this quality are few and far between from Tasna.

Ferberite (very aesthetic group)

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 5.2 x 4.8 x 4.2 cm (small cabinet)


A highly aesthetic and really dramatic Ferberite specimen, not only from Bolivia, but any world locality. The biggest problem with a lot of “black” rocks (because of my affinity for them, I like to call them “black beauties”) is the fact that they’re not always terribly aesthetic. THIS piece is one of the most eye-catching Ferberites I’ve seen. This incredibly three-dimensional and sculptural display specimen features a beautiful, sharp, very well-formed, multi-twinned group that is actually DOUBLY-TERMINATED !! If that wasn’t enough, the twins are beautifully intergrown with sharp, layered blades of Ferberite on the side. The piece displays well on its own from a few angles, and the piece is in great shape all around, and certainly is even more impressive in person. Ferberite was sometimes previously referred to as "Wolframite", which was supposed to be an intermediary species between Ferberite and Hubnerite, but has since been discredited. Bolivian Ferberites (especially those from Tasna) are often and sadly underrated/overlooked, but in many instances will surpass other Ferberites from Yaogangxian or Panasqueira for size and quality.

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 4.8 x 2.3 x 2.1 cm (miniature)


A wonderfully well-crystallized, and eye-catching “closed” twin of Ferberite with great form, sharpness and luster is coated by spherical aggregates of pale golden Marcasite and minor grey Arsenopyrite. The piece is virtually undamaged on the display side and when propped up, the piece displays beautifully. Good Bolivian Ferberites are often not found with any associated minerals, especially with any kind of aesthetic appeal like this one. It’s a great full-sized miniature to boot!

Ferberite (twin)

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 3.5 x 3.1 x 3.0 cm (miniature)


An impressive and attractive twinned Ferberite from Tasna. This species was sometimes previously referred to as "Wolframite", which was supposed to be an intermediary species between Ferberite and Hubnerite, but has since been discredited. This eloquent piece is sharp, highly lustrous, jet black twinned crystal of Ferberite (twinned along the a{100} face). For a final aesthetic touch, one can see a sparkling spherical aggregate of Marcasite on the top (or bottom depending upon the angle) of the twin! The piece has a small contact towards one of the corners, but considering that the large majority of Ferbs from Tasna have serious damage problems, this one is in great shape, and displays well from a few angles. The luster is better than the majority of the Ferberites from this mine, and the piece is complete on both the top and bottom, and is not cleaved, which is impressive as most of the Ferberite twins are broken on one end. Bolivian Ferberites (especially those from Tasna) are often and sadly underrated/overlooked, but in many instances will surpass other Ferberites from Yaogangxian or Panasqueira for size and quality.

Ferberite (doubly-terminated twin) with Quartz

Locality: Tasna Mine, Rosario section of Cerro Tasna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia

Specimen Size: 2.8 x 2.8 x 2.1 cm (thumbnail)


A VERY rarely seen doubly-terminated Ferberite twin from Tasna. This specimen is an impressive, fairly sharp, semi-lustrous DOUBLY-TERMINATED twin which is only seen in a very small percentage of pieces from Tasna. A few small gem Quartz crystals on the side of the piece make for a great accent to this already eye-catching little specimen. The back of the twin has a “rub” which keeps it from being completely perfect, but it’s more than forgivable considering that there virtually every Ferberite from Tasna has some kind of imperfection. The piece truly looks better in person as Ferberite is a difficult species to accurately photograph, so much so that we decided to draw a red “X” on one of the photos to help illustrate the twinning planes. A more than worthwhile Ferberite that would make a great addition to any collection.

Ludlamite (unique sphere-shaped aggregate)

Locality: Huanuni mine, Huanuni, Dalence Province, Oruro Department, Bolivia

Specimen Size: 3.5 x 2.7 x 2.1 cm (miniature)
Ludlamite Group: 8 mm


This is without a doubt one of the most distinctive Ludlamites I have seen from Huanuni. Typically, the Ludlamites from this locality are found in fan-like “sprays” or even “bow tie”-shaped aggregates, but to find a sphere-shaped aggregate like this is exceedingly rare. Additionally, the vast majority of the Ludlamites from this mine are found on Pyrite or Limonite matrix, and to find them associated with Quartz is also incredibly rare. The Ludlamite “ball” on this piece is virtually undamaged, and has a pleasing rich green color with good luster and translucence. The final touch to the piece is sitting on rarely seen Quartz and Siderite matrix with minor black Cassiterite. It’s a fairly aesthetic specimen with the Ludlamite “ball” smartly propped up at the top of the piece, and it displays well from a few angles. If you’re a Bolivian collector, or a phosphate collector, or if you like unusual, rare, colorful minerals, then be sure to pick this one up as it’s the only one like it that I have to offer. There are truly about 5 localities in the world that produce fine crystallized Ludlamite specimens, and ALL of them, except for Huanuni and now defunct. PLEASE NOTE: There have been no more of these specimens found for several years from this locality, and it is a possibility there will never be any more, so don't miss out on a good quality and uncommon piece from a classic Bolivian locality.

A beautiful Ludlamite specimen from the famous mine at Haununi. This mine is actually the LARGEST Cassiterite deposit in the world, but is best known for its phosphate species. There are truly about 5 localities in the world the produce fine crystallized Ludlamite specimens, and ALL of them, except for Huanuni and now defunct. This piece features a pair of beautiful “sunburst”-like sprays of pleasing green color Ludlamite with good luster, sharpness and translucency/gemminess sitting on wonderfully contrasting brownish Limonite with golden metallic underlain Pyrite. Great condition overall, and a superb representation of the species and the locality. PLEASE NOTE: There have been no more of these specimens found for several years from this locality, and due to newly imposed circumstances regarding the removal of specimens from the mine, it is a possibility that we may not see any Ludlamites from Huanuni for a long time.

Augelite with Chalcanthite

Locality: Machacamarca Mine, Colavi, Saavedra Province, Potosi Department, Bolivia

Specimen Size: 7.5 x 5.1 x 2.5 cm (small cabinet)
Largest Crystal: 6 mm


This specimen was collected in 2004, and the pieces from this find were some of the best Bolivian Augelite crystals to hit the mineral market in a long time. This piece features several fine, sharp, lustrous, colorless, gemmy crystals of Augelite associated with blocky whitish Barite and small Quartz crystals and Pyrite on matrix. The reverse side of the specimen shows exceedingly rare, bright electric blue Chalcanthite, which I have only seen on a few pieces from this locality. Augelite is not seen often in any format from any locality, and for a Bolivian Augelite, this is a good representative piece, especially with the wonderful Chalcanthite association!
