Cyanotrichite with Brochantite, Azurite, Malachite and Chalcoalumite

Locality: Grand View Mine, Cape Royal, Horseshoe Mesa, Grand Canyon National Park, Coconino County, Arizona

Specimen Size: 20.4 x 11.2 x 9.7 cm (large cabinet)


A superb large cabinet size display specimen of one of the most beautiful mineral species out there !! Cyanotrichite is a Copper Aluminum Sulfate and well-crystallized specimens in this size are next to impossible to obtain. The piece was collected in the mid 1960's by Leigh Price in the Grandview mine, which existed inside of the Grand Canyon! The mine is long defunct, and totally inaccessible, but when specimens were being recovered, they were some of the most incredible, and brightly colored specimens from Arizona, or anywhere else for that matter. This specimen consists of hundreds of excellent, bright blue color, acicular (needle-like) radiating aggregates or "sprays" of Cyanotrichite associated with dark green Brochantite, lighter green Malachite, deep royal blue Azurite and pale blue Chalcoalumite on matrix. The needles of Cyanotrichite are very delicate, but are equally stunning to view. You can see that Angela has provided some great photos of what these crystals look like close up. Please note that there have been almost NO specimens from this locality available on the market for a very long time. This is a very rare opportunity to own a unique and attractive association specimen from one of the more interesting localities in the United States. Very fairly priced for the size and obscurity of the material.

Quartz (var: “Smoky”) with Microcline and Albite

Locality: Glens Peak, Sawtooth Mountains, Elmore County, Idaho

Specimen Size: 24.5 x 18.1 x 7.3 cm (large cabinet)


ex.  Richard and Tresa Kosnar


Shortly before I was born, my parents went to Idaho to collect in the various pegmatites in the wilderness of the Sawtooth Mountains. Along with finding some of the finest natural color Aquamarine crystals from virtually any world locality, they collected some excellent specimens around Glens Peak. This specimen is the largest association “plate” from this area that I’ve seen. It’s a classic miarolitic cavity display piece featuring stark crystals of Smoky Quartz associated with pale beige to light pink Microcline and fairly lustrous, somewhat blocky little crystals of white Albite. Despite some nicks here and there, the specimens is in great shape overall and the fact that something this size was removed in one piece is certainly notable. Imagine the size of the pocket that yielded a solid plate this large. A beautiful and highly displayable piece from this remote region in the northwestern United States.

Copper

Locality: Houghton County, Michigan

Specimen Size: 31.9 x 27.2 x 4.6 cm (large cabinet)


The “Copper Country” of the Upper Peninsula of Michigan is undeniably one the most substantial mineral deposits in the western hemisphere. In its heyday, the area was the world's greatest producer of native Copper, and is best known not only for producing superb crystallized examples, but large display specimens to boot! Here we have a very dramatic, impressive, showy display piece featuring arborescent, or dendritic, growths of crystallized Copper flaring out like a large piece of metallic, branching fire coral. It is essentially crystallized all the way around, although crudely in many areas. The classic patina that is characteristically seen in the top specimens from this area is clearly exhibited in this eye-catching beauty. These specimens are becoming more and more difficult to find on the market today, and this is a very good sized specimen of this most highly sought after material from Michigan. Good crystallized cabinet sized Coppers from this area are amongst the most desirable of all native elements for collectors. For sheer size and aesthetics you can’t deny that this one is a powerfully poignant Copper from any locality. Very well priced for the amount of Copper present!

Quartz

Locality: Red Feather Lakes, Larimer County, Colorado

Specimen Size: 17.8 x 12.2 x 9.4 cm (large cabinet)
Largest Crystal: 6.6 cm


ex.  George Robertson


A notable specimen of lustrous, well-formed, hexagonal prisms of Quartz with minor reddish-brown Hematite tinting from the famous Red Feather Lakes area in northern Colorado. Well known Colorado collector George Robertson actually gave this piece to me (more appropriately my parents) as a present for my first birthday after a digging trip to the area a few months prior. This specimen is one of the largest presentations from this locality that I have seen with minimal damage and enough outward appeal to make it really stand out. A special piece to me, especially because it came from George, and the fact that it’s one of the better non-ore body Quartz specimens that I have owned from Colorado.

Chabazite on Prehnite from Upper New Street Quarry, Paterson, Passaic County, New Jersey [./lgcb812/lgc81205a.JPG] Chabazite on Prehnite from Upper New Street Quarry, Paterson, Passaic County, New Jersey [./lgcb812/lgc81205b.JPG] Chabazite on Prehnite from Upper New Street Quarry, Paterson, Passaic County, New Jersey [./lgcb812/lgc81205c.JPG] Chabazite on Prehnite from Upper New Street Quarry, Paterson, Passaic County, New Jersey [./lgcb812/lgc81205d.JPG]

Chabazite on Prehnite

Locality: Upper New Street Quarry, Paterson, Passaic County, New Jersey

Specimen Size: 15.4 x 9.7 x 5.6 cm (large cabinet)
Largest Crystal: 1.2 cm


The quarry at Upper New Street is over 100 years old (it opened in 1893). During the mid 1980's to early 1990's, there was a lot of collecting that took place between the Upper New Street and Lower New Street Quarries in an area that is affectionately referred to by some as "Middle New Street". The majority of the specimens from this area are still labeled as being found at Upper New Street even though they were not found in the quarry itself. Nonetheless, this is one of the most famous Trap Rock quarries in New Jersey and is probably most famous for its amazing and unique Prehnite casts after Anhydrite (sometimes called "fingers" or "snakeheads"). This specimen features several sharp, lustrous, pearly, pseudo-rhombohedra of Chabazite associated with green Prehnite on basalt matrix. The Chabazites are mostly white, but they do have a faint peach-pink color in areas, which is rare in my experience with this material. This mineral is not seen in well crystallized specimens from many localities, and the color contrast of this piece combined with the fact that it is from a now defunct locality makes it a very attractive and desirable East Coast classic.

Quartz (var: “Amethyst” and “Smoky”) from Petersen Mountain, Hallelujah Junction, Washoe County, Nevada [./lgcb812/lgc81206a.JPG] Quartz (var: “Amethyst” and “Smoky”) from Petersen Mountain, Hallelujah Junction, Washoe County, Nevada [./lgcb812/lgc81206b.JPG] Quartz (var: “Amethyst” and “Smoky”) from Petersen Mountain, Hallelujah Junction, Washoe County, Nevada [./lgcb812/lgc81206c.JPG] Quartz (var: “Amethyst” and “Smoky”) from Petersen Mountain, Hallelujah Junction, Washoe County, Nevada [./lgcb812/lgc81206d.JPG]

Quartz (var: “Amethyst” and “Smoky”)

Locality: Petersen Mountain, Hallelujah Junction, Washoe County, Nevada

Specimen Size: 19.6 x 12.2 x 9.3 cm (large cabinet)


Here we have a great Smoky Quartz and Amethyst specimen from a 2006 find in the Hallelujah Junction area along the California-Nevada border. I obtained this specimen directly from the man who collected it. It has very good form and color, for any locality, but is especially attractive for a U.S. piece. This specimen consists of a large, sharp, lustrous, translucent, well formed, partially skeletal and partly sceptered, crystal group with defined smoky and purple "Amethyst" bicolor zoning. Some minor contacts around the specimen keep it from being a world-class Quartz. It is not complete on the back, but most people recognize this area as one of the premier Quartz producing regions in the United States today, and pieces this size are not terribly common, and are becoming more desirable amongst collectors, so some damage is forgivable in my mind.

Barite

Locality: Elmwood Mine, Carthage, Smith County, Tennessee

Specimen Size: 21.1 x 17.6 x 11.3 cm (large cabinet)


A GIANT “snowball”-shaped crystallized group of translucent, ivory colored Barite from the famous Elmwood Mine. This locality is known for producing a handful of species, but a few of them are some of the most noteworthy mineral specimens from the United States. The Elmwood Mine is also well known for producing large and highly displayable examples of these specimens. Taking into consideration the contact on the bottom side/edges, this piece is very competitively priced for the dramatic size. Please note that the piece weighs over 15 pounds, so shipping will be approximately $70 according to the USPS as of August 2012.

Barite on Sphalerite

Locality: Elmwood Mine, Carthage, Smith County, Tennessee

Specimen Size: 16.3 x 15.8 x 7.2 cm (large cabinet)
Barite “Ball”: 8.1 cm


This locality is known for producing a handful of species, but a few of them are some of the most noteworthy mineral specimens from the United States. The Elmwood Mine is also well known for producing large and highly displayable examples of these specimens. This wonderful large cabinet specimen features a “snowball”-shaped crystallized group of translucent, ivory colored Barite sitting on crystallized, highly lustrous, “Ruby Jack” Sphalerite matrix. Honestly, there is no real damage to speak of on the display side, and the Sphalerites are even dotted with a few small golden Calcite crystals. With great aesthetics and quality overall, this one stands out as being more than a simple Barite from Elmwood. A highly desirable association specimen from this world-class locality.

Hemimorphite

Locality: San Antonio Mine, East Camp, Santa Eulalia District, Mun. de Aquiles Serdán, Chihuahua, Mexico

Specimen Size: 23.4 x 11.7 x 10.3 cm (large cabinet)


Some of the world's finest Hemimorphite specimens have come from the Santa Eulalia area in Mexico. These specimens are some of the most aesthetic and eye catching pieces from this locality. This specimen features dozens of VERY good sized, gemmy/translucent, sharp, lustrous, individual prismatic crystals of white to colorless Hemimorphite on gossan matrix. For the size, quality and overall aesthetics of this specimen, it is a great Mexican display piece from this classic locality.

Fluorite

Locality: Naica Mine, Naica, Mun. de Saucillo, Chihuahua, Mexico

Specimen Size: 16.4 x 9.2 x 6.0 cm (large cabinet)
Largest Fluorite: 4.3 cm


ex.  Frank Daniels


A gorgeous, "water-green" color, GEM quality, sharp, lustrous, intergrown cuboctahedral crystal group of Fluorite sitting atop minor associated Galena and Pyrite. This piece is not from a recent find at the mine, but actually about 30 years ago (late 1970s). For the quality, it is a desirable large cabinet from this incredible locality. The Fluorites are stunning in their transparency, so much so, that they are very difficult to accurately photograph. Some peripheral damage can be seen on the piece, but it certainly is not a deterrent in my opinion. The specimen came from the well-known collection of Frank Daniels.

Gypsum (var: “Selenite”) (“fish-tail” twins)

Locality: Naica Mine, Naica, Mun. de Saucillo, Chihuahua, Mexico

Specimen Size: 21.6 x 16.2 x 13.3 cm (large cabinet)
Largest Twin: 9.1 cm


A superb representation of the famous “fish-tail” twinned Selenite Gypsum specimens from the incredible Naica Mine in Mexico. Many people have seen the footage of the immense “Cave of Swords” inside of Naica that is filled with multi-thousand pound crystals of Gypsum that dwarf anything ever seen before. Gypsum might be the most famous mineral from Naica due to the intense media coverage that has surrounded the discovery of these incredible underground “caves” – it’s really a series of giant Gypsum pockets!! This piece is a fantastic example of the older material from Naica, which was found 30-40 years ago. The crystals have beautiful satiny luster with excellent gemminess and the classic form that made these specimens so desirable.

Rhodochrosite

Locality: Manuelita Mine, Morococha District, Yauli Province, Junín Department, Peru

Specimen Size: 22.7 x 16.8 x 8.3 cm (large cabinet)


A marvelous large cabinet Rhodochrosite specimen featuring dozens of sparkling, soft pink botryoidal groups on matrix. Some of the “balls” are actually hollow underneath, indicating that they probably have formed as an epimorph or “cast” after a preexisting mineral. No real damage to speak of, and truly eye-catching for the material. You just don’t see big display specimens of Rhodochrosite like this from any locality on the market, and this particular piece is very fairly priced considering that it measures nine inches across!

Pyrite

Locality: Quiruvilca Mine (La Libertad Mine; ASARCO Mine), Quiruvilca District, Santiago de Chuco Province, La Libertad Department, Peru

Specimen Size: 15.3 x 14.3 x 7.9 cm (large cabinet)


A remarkable Pyrite from the famous Quiruvilca Mine in Peru. This superb specimen shows exceptionally large, sharp, intergrown pyritohedra with wonderful metallic luster. Even though the periphery of the specimen is contacted, the back of the piece is partially crystallized(!), which is rare in my experience with larger Pyrites from this mine. Often, Pyrite is not found in crystals over a few inches, and a piece like this in such amazingly fine condition is certainly rare on the market. This piece was mined in the early to mid 1970’s.

Hydroxylapatite on Microcline

Locality: Sapo mine, Ferruginha, Conselheiro Pena, Doce valley, Minas Gerais, Brazil

Specimen Size: 22.7 x 20.0 x 9.5 cm (large cabinet)
Largest Crystal: 3.5 cm


In 2004 some of the most unique and eye-catching specimens of Hydroxylapatite were discovered. These pieces feature flattened dipyramidal crystals with the most unusual and eye-catching bicolor blue-green and yellow zoning. The majority of the specimens were found on "buff" color Microcline, and this monster specimen is no exception. It’s easy to say that these are some of the most distinctive Apatites in the world, and of great interest to collectors. It has to be said that these are the finest Hydroxylapatite specimens extant, certainly from the standpoint of color. Readers of the Mineralogical Record know that the Sapo Mine in Brazil was profiled in the July/August 2009 issue. This piece is very fairly priced compared to smaller pieces on the market with smaller crystals.

Specimen Size: 19.8 x 11.0 x 7.3 cm (large cabinet)
Largest Cassiterite: 1.8 cm


ex.  Richard A. Kosnar


This is the finest specimen that I’ve handled from this lesser known greisen deposit in bleak Siberia. A fairly large and hefty, doubly-terminated, slightly “smoky” Quartz crystal group plays host to several sharp, lustrous, mostly black, well-formed, prismatic tetragonal Cassiterite crystals (some of which have formed “drill bit” twins) which are dotted along the prism of the Quartz. If you are a Russian mineral collector, or if you appreciate large Quartz / Cassiterite association specimens, don’t miss out on this fairly priced mineral specimen. From my father’s collection (specimen #Sn/Qtz 895 R), who obtained it directly from Gene Foord who traded it after a visit to the former Soviet Union. The piece was valued at $3000 at the time.

Fluorite

Locality: Le Burg Mine, Alban - Le Fraysse area, Tarn, Midi-Pyrénées, France

Specimen Size: 20.5 x 13.3 x 6.2 cm (large cabinet)
Largest Crystal: 3.4 cm


This well-known mine near Tarn in France is essentially an impressively large vein of nearly solid Fluorite that measures nearly three quarters of a mile long. The vast majority of the specimens from the mine are blue in color with superb gemminess, color, luster and form. Centuries ago, this locality was apparently mined for Copper, and was remarkably rediscovered in 1945 and mined from 1954 until April 2006 for Fluorite. Mining went nearly 1,000 feet underground and produced an amazing 650,000 tons of Fluorite. When it closed, it was the last Fluorite mine in France. Typically, the specimens from this mine are riddled with damage, but this beautiful display specimen is in very good shape showing beautifully transparent / gemmy, rich blue to green color sharp, lustrous intergrown cubes of Fluorite. The yellow spot on the specimen is caused by underlain iron, but makes for a beautiful contrast. Like most blue Fluorites from any world locality, the color is best viewed in sunlight, where it is more intense / saturated. No serious damage on this one, only a few minor nicks here and there, certainly better than the vast majority of specimens I’ve handled from the locality. These are surely some of the finest contemporary Fluorites from any world locality. This particular piece was collected in 2004.

Calcite with Malachite

Locality: Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia

Specimen Size: 20.8 x 15.5 x 9.6 cm (large cabinet)
Largest Crystal: 2.0 cm


Tsumeb is amongst the most prolific of localities in the world, arguably the most significant locality extant, at least from the standpoint of the minerals found there. This excellent large cabinet display specimen is loaded with dozens of highly lustrous, off-white color, sharp, very well-formed rhombohedra of Calcite which are associated with forest green color “velvety” Malachite. Additionally, some micro emerald green Dioptase and olive green Duftite can be seen on the specimen as well. How often does one encounter such a large, fine quality mineral specimen from the most classic of localities in such amazingly good condition? The photos are great on this one, and it looks even better in person!

Stellerite

Locality: Aurangabad District, Maharashtra, India

Specimen Size: 20.2 x 15.7 x 8.2 cm (large cabinet)
Largest “Ball”: 6.0 cm across


Fine crystallized Stellerites are only found in a handful of world localities, and to find one in a large cabinet specimen such as this is remarkably rare. The quality of this particular Stellerite is nearly as good as the species gets, especially from the standpoint of size. It comprises dozens of sheaf-like crystals which have formed into spherical aggregates creating a very visceral and aesthetic overall specimen. It has top luster with a smooth creamy beige color and is nearly completely undamaged on the display side. One does not encounter Stellerites like this from any locality, and the quality leaves nothing to be desired. If you are a Zeolite collector, or simply enjoy outstanding large specimens of minerals that are seldom seen in such quality, do not miss out on this significant piece.

Azurite and Malachite

Locality: Liufengshan Mine, Guichi District, Chizhou Prefecture, Anhui Province, China

Specimen Size: 17.8 x 14.5 x 13.3 cm (large cabinet)


This is a dramatic large cabinet display specimen of Azurite on Malachite from the prolific Liufengshan mine. It features thousands of tiny, sharp, lustrous, midnight blue Azurite blades which have formed in pseudo "rosette"-shaped aggregates and are scattered atop deep forest green (mint green underneath) Malachite on matrix. The color contrast is just beautiful and truly resembles classic material from Bisbee. The specimen displays beautifully, and really draws one's attention. For a specimen of this size, it is very showy and is one of the better "big" pieces of this material that I have handled. These specimens are commanding high prices, even from the Chinese dealers.

Calcite (Manganoan)

Locality: Shizhuyuan Mine, Dongpo ore field, Yizhang Co., Chenzhou Prefecture, Hunan Province, China

Specimen Size: 20.2 x 13.3 x 11.7 cm (large cabinet)


A beautiful, light pink color, "pagoda"-style crystal group of compressed, stacked Calcite "poker chip"-shaped rhombohedra creating a very attractive display specimen. The crystals are actually overgrowing a first generation of scalenohedral Calcites to create the “spires”. These are great contemporary Chinese classics showing superb form with great displayability. Get these while you can because they won't last forever, and for the overall quality, this is a good large cabinet-sized display piece of these very attractive Calcites. Despite a few rough spots, it's still a worthwhile Mn-Calcite from what is arguably the most productive mineral producing country of the last 10 years.

Quartz “cast” after Anhydrite

Locality: Xiefang Mine, Ruijin Co., Ganzhou Prefecture, Jiangxi Province, China

Specimen Size: 19.2 x 14.4 x 6.2 cm (large cabinet)


A beautiful display specimen found about a year ago (June of 2011) in China featuring rather lustrous, sparkling, “sugary” white Quartz crystals which have formed amazingly distinct hollow “casts” or epimorphs after preexisting Anhydrite crystals. It should be noted that the “casts” could have formed after Glauberite, but the striations to me are indicative of Anhydrite, despite the somewhat blocky monoclinic form that can be seen on the underside of the specimen. This is the best specimen of these casts that I have handled, and they were very limited in their production. More than just a Quartz specimen, and truly impressive from the standpoint of the actual epimorphs. Superb quality and very reasonably priced for what it is.

Calcite

Locality: Fengjiashan Mine (Daye Copper Mine), Daye Co., Huangshi Prefecture, Hubei Province, China

Specimen Size: 17.1 x 13.8 x 8.4 cm (large cabinet)


A wonderful Calcite specimen comprising superb, attractive, large, razor-sharp, highly lustrous, translucent, pale-pink (iron-included) to nearly colorless twinned scalenohedra. When it comes to Chinese Calcites, Daye Co. has produced some of the finest extant, and this one is no exception. Virtually all of the crystals are pristine, save one at the bottom that unfortunately is cleaved. Otherwise, the piece is in great shape and due to its depth and three-dimensional quality, is very difficult to photograph, so it does look better in person.

Hemimorphite

Locality: Wenshan Mine, Wenshan Co., Wenshan Autonomous Prefecture, Yunnan Province, China

Specimen Size: 24.7 x 14.8 x 6.7 cm (large cabinet)


This very showy plate from Wenshan, China features a very desirable color, close to "electric-blue", botryoidal Hemimorphite forming a thin “crust” on matrix.  The electric color has made these the most popular specimens, though hard to get.  The Hemimorphite is fairly lustrous - a Smithsonite-like luster - and actually slightly translucent.  The color in person is even more intense than the photo shows.

Calcite

Locality: Fengjiashan Mine (Daye Copper Mine), Daye Co., Huangshi Prefecture, Hubei Province, China

Specimen Size: 16.2 x 13.0 x 7.8 cm (large cabinet)


One of the better examples of these exciting lavender or lilac colored scalenohedral Calcite specimens from the famous Daye Copper Mine in China. A very lustrous, satiny, translucent, lustrous, well-formed, beautifully colored crystal group sits on a thin amount of matrix. The piece was difficult to photograph, and gorgeous in person, even when considering the cleavage on the base of the crystal. The main display side of the piece is virtually damage free, with only the smallest of imperfections on the side of the crystal. If you’ve wanted one of these stunning Calcites for your collection, look no further, as this one is priced to sell, especially when compared to some of the 5-figure specimens that we have seen on market recently.

Spessartine on Quartz (var: “Smoky”)

Locality: Wushan Spessartine Mine, Tongbei, Yunxiao Co., Zhangzhou Prefecture, Fujian Province, China

Specimen Size: 16.2 x 11.7 x 8.8 cm (large cabinet)


These Spessartines are some of the most attractive and highly displayable specimens to come out of China. This particular piece features several hundred lustrous, gemmy, strong orange, trapezohedral crystals of Spessartine measuring up to 5 mm sitting on a pair of stout, very dark (“Morion”) Smoky Quartz crystals on beige Microcline matrix. The color in the Spessartine crystals is very attractive, and they are not at all dull or pitted. This material is becoming less and less available on the market, and keep in mind that there are only a few worldwide localities that produce this color of Spessartine in fine specimens. Gem orange Spessartine specimens are NOT easy to find these days from any locality, especially on matrix, and with good associated minerals. Good specimens from this area seem to have dried up in recent years, and will only increase in value the same as additional orange Spessartines from other worldwide localities such as the Little Three Mine in California.

Prehnite (unusual “fingers”)

Locality: Balochistan (Baluchistan), Pakistan

Specimen Size: 24.6 x 23.1 x 5.8 cm (large cabinet)


These are some of the most unusual Prehnites I have seen from any locality. At first glance, one might think that these are "casts" or epimorphs after another species, as Prehnite has been known to do, but upon close inspection you can see that these are completely solid inside, and are basically Prehnite stalactites or non-epimorphic "fingers". Some of these "fingers" are broken and show a radial growth pattern in the center. Really strange for the species. I have only seen a handful of these specimens on the market, and nothing new for several years. This particular piece, despite the larger size, does have some contacts here and there, hence the reduced priced.

One of the great Alpine staples for any collector is the classic Adularia specimens from the Swiss Alps. Historically, Adularia was classified as a variety of Orthoclase, but it is now defined as “a more ordered low-temperature variety of Orthoclase or partially disordered Microcline”, so now everything labeled as Adularia is classified as being a potassium Feldspar. This piece is from my father’s Alpine collection (#Adular 694 S), and was the best large cabinet Adularia that he owned. It features dozens of sharp, incredibly well-formed, pseudo-rhombohedral (monoclinic), “wedge”-shaped crystals – some of which are twinned – which range from porcelain white to translucent / pearlescent in clarity. The rich moss-green color is due to a coating of Chlorite, which grades from a very gentle dusting to a full-on inclusion, creating entirely “green” Adularia crystals. Nearly all of the crystals are pristine, and if that wasn’t enough, the specimen can be displayed from either side, creating a completely different perspective that either shows the subtle green and white contrast on one side, or the stark green appearance created by an abundance of Chlorite on the other. This is a beautiful specimen from this very historic and well known region in Switzerland. The piece comes with two of my Dad’s labels as well, although one is only a photocopy as the original was actually stolen in Tucson earlier this year.
