Several Quartz veins are located south of the provincial town of Bastogne (known throughout the world because one of the most important battles of world war II was fought there, the battle of the bulge). The Quartz veins straddle the Wardin fault (faille de Wardin) that follows a rough line between the villages of Lutrebois, Marvie, Wardin and Schimpach (Luxemburg) in a north-east direction. Pockets in these sometimes very wide Quartz veins are usually filled with red pocket mud containing a lot of Iron, also Hematite (as "Glaskopf" ) and Limonite are usually present in the pockets. This is why the Quartz veins were mined, to take out the Iron rich pocket mud, Limonite and Hematite and throw away the Quartz, leaving nice crystals for collectors centuries later......Most of the occurrences are either on private property or state owned property so no searching for minerals should be undertaken without the authorisation of the land owner.

On the dumps of an ancient Iron prospect in a Quartz vein near the small village of Wardin many very nice specimens have been found in the year 2006 and 2007, they came in pretty groups up to 20 cm as well as loose crystals up to 12 cm in length. Of special interest is the fact that Faden crystals were quite common, as well a double terminated crystals.

Near the small village of Marvie nice Quartz specimens have been found recently in an old Iron prospect in a Quartz vein as well as from a forest road that cuts through a succession of Quartz veins. Some of the pockets contain Chlorite and many of the Quartz crystals from these pockets are Chlorite included, sometimes showing attractive phantoms. Also on the fields around the villages of Marvie and Wardin one can find good Quartz specimens (along with the odd world war II hand grenade!!)

In the 1970s and 80s several fissures were encountered in Les Roches quarry (on the edge of Bastogne town). They showed a nice Alpine type mineralogy; excellent slightly smoky Quartz crystals accompanied by Titanite, Apatite, Anatase and Chlorite. Some very fine examples reside in private collections in Belgium.

South of the village of Bertrix several localities produced fine Quartz specimens. The localities are situated on the edge of La Haie Forest.

What I consider (in my humble opinion) to be the most aesthetic Quartz specimens from Belgium are the Amethyst sceptres that were recovered from a Quartz vein near the village of Salm-Chateau. The Scepter crystals could get up to 5 cm in length and the most beautiful specimens were those where the Amethyst sceptres are neatly sitting inside Turquoise lined pockets, amazing!

Around the small town of Vielsalm Cotticule has been mined in many mines and quarries, Cotticule is a metamorphic rock containing many small Spessartine Garnets. It is used as an abrasive stone for sharpening razor blades and knives and has been marketed world wide. Nowadays only one quarry in the nearby town of Lierneux remains active producing Cotticule (now a luxury item whereas it used to be a household item...)
The Cotticule is intersected by small Quartz veins and inside pockets in thos veins nice small Quartz crystals could be found, often as sceptres. Apart from those a long list of interesting micros occur in them, most notable excellent Turquoise (also as single crystals)

In Brabant Province a couple of very large scale quarries exploit Porphyre, a very hard eruptive rock. Spectacular Quartz crystal have come out of the quarries of Quenast, Deux-Acren, Lessines and Bierghes.

On a field 2 km north of the small village of Amay many nice Quartz crystals were found in the 1970s.
Many of the Quartz crystal show a slight smoky colour and many are double terminated. Interestingly also quite a few Fensterquarz crystals were found.
A short story about the discovery of the locality: The doctor of Amay happened to be a mineral collector and had a small display cabinet with some minerals in his waiting room. One day a local farmer came to see the doctor and noticed the minerals in the waiting room upon which the farmer said to the doctor: "oh, I've got lots of those scattered around on my field". After asking for the exact spot and permission to dig in the field the doctor collected many nice crystals together with Jose Dehove (info Jose Dehove).

Of all the quartz localities in the United States, certainly the best know are the various localities in Arkansas. They have been producing quartz crystals for more than 100 years and were even used occasionally by the Indians to make arrowheads. They are seen in collections all over the world and production continues today. There are many different varieties of quartz, perhaps amethyst, agate, opal and petrified wood are among the best known. We will try and include them all here. What localities produce the best specimens of quartz and quartz family minerals? Well, certainly the Quartz from Arkansas would have to rank high on the list. Good amethyst specimens are always in demand by collectors, and those from Georgia can sometimes be spectacular, and those from Montana can also be quite nice. Not all varieties of Quartz need to be form in crystals to be highly valuable. Specimens of "gem silica" (agate colored blue by Chrysocolla) from Arizona can bring thousands of dollars per specimen. Though not quartz in a technical sense, we are including opal here because it is chemically very similar to quartz. Fire opal limb casts from Idaho can also bring high prices. Big, meter plus, slabs of fine petrified wood from Arizona can sell for tens of thousands of dollars. Specimens of quartz showing well formed examples of Japan Law twinned quartz are always popular with collectors and in this section of Quartz, Alabama to Montana fine examples from Arkansas and California may be best. Often times the quartz crystals from various localities are nice but not outstanding, but when they occur growing together with other minerals, those specimens can be worth many times what specimens of just the quartz would bring. A prime example of this are the smoky quartz crystals from Colorado that are sometimes found growing with beautiful blue amazonite crystals.

Of all the common minerals, quartz is probably the most durable. On mindat, the most often hit upon mineral is quartz, and on Mindat's Message Board in the Mineral Cleaning and Preparation forum the most commonly asked questions are about hot to clean quartz specimens. You can scrub up your quartz specimens to your hearts content and even subject them to most strong acids without fear of damaging them. You can even cook them in crock pots with out worry. If you want to clean your quartz specimens, here is a link to an article that will tell you all about cleaning your quartz specimens and what you can do and should not do. [www.mindat.org].

The specimens pictured above are most likely from one of the Prince of Wales Island localities listed below, but I thought they were interesting enough to include them here even thought they have "lost" their exact localities. The Prince of Wales Island locality is much better know its fine stout black Epidotes than the few quartz specimens it produces. The good Japan Law quartz twin pictured below left may be the best one ever found at the locality and it may be ten times better than the next best one. The locality is remote, and to reach it you have to mount a major expedition or more commonly you hire an airplane that will land you a lake up in the mountains near the mine, camp in a little forest service cabin and each day hike up the mountain to the steep area where the epidote is found and then spend the day, often in the rain working with hand tools to remove the vegetation from the face of the mountain to see if you can expose any pockets of epidote and quartz crystals. The production of specimens from this locality will never be great, and if you have any good ones from there, you should cherish them.

Technically speaking the specimens pictured above are really more Wulfenite specimens than quartz specimens and appear here only because the Wulfenite crystals from this locality are commonly coated with drusy quartz. These are rather rare creatures and in spite of having lived and collected in California and Arizona most of my life, I have never managed to get a good one.

Quartz v. "gem chrysocolla" 5.7cm	© Rob Lavinsky


Quartz, Chrysocolla & Malachite, 4.9cm	© Rob Lavinsky

The piece of gem chrysocolla pictured on the left above would not look quite like that when the miner collected it. The high spots on the specimen have been polished up a bit and that is what makes them shine. If you look down in the valleys between the high spots you can see what was the natural luster of the specimen when it was collected. "Gem Chrysocolla" is almost entirely the chalcedony variety of quartz with just enough Chrysocolla in it to give it a pleasing blue color. Pure Chrysocolla is a pretty blue color, but on exposure it tends to crack and fall apart, but "gem chrysocolla" on the other hand is almost pure chalcedony, quite hard and takes a beautiful polish and is therefore ideal for making cabochons. When just the right amount of Chrysocolla and perhaps other copper minerals are present in the chalcedony, to give it just the right amount of blue color and the right amount of translucency, the price of finished stones for jewelry can be more than $100 per carat. So if you can get a piece of good gem chrysocolla that weighs a kilogram it has the potential of cutting perhaps 1000 carats of finished stones which could sell for $100,000. Thats not bad for a small rock that a miner might bend over and pick out of a blast pile in a large open pit copper mine. At the right time you could probably fill us the back end of a pick up truck in an hour or two and drive off into the sunset and never work another day the rest of your life.

Quartz v. chalcedony & chrysocolla, 11.9cm wide	© Rob Lavinsky

Drusy quartz growing on Chrysocolla and chalcedony colored blue by chrysocolla has been found at number of copper mines, but perhaps the most impressive locality for this kind of item is Inspiration mine in the Globe-Miami District. The color alone makes many collectors drool uncontrollably and when you add to this the gem value of good quality "gem chrysocolla" and you can come up with some very expensive specimens/cutting rough. Often these specimens are also associate with Malachite ond sometimes other Back on the 1950's the good grade gem Chrysocolla from the Live Oak pit was going for about $100 per pound. Today it can bring several thousand dollars a pound for specimens with just the right color and translucency. Good grade cabochons of "gem chris", can bring prices of $100 per carat. The Taiwanese Chinese are particularly attracted to this material. I have a number of good specimens of this material in my collection, including drusy specimens, but have thus far resisted the temptation of selling them for fear that their fate is most likely the cutters wheel.

The location of Stanley Buttes has been know to collectors for generations and and is much better know for its good specimens of yellow/brown/green specimens of Andradite garnet specimens. In the early days field collectors collected there pretty much as they pleased but as time passed the reservation Indians started started patrolling the borders of their reservation and kicking field collectors out. Today it is considered off limits to field collectors. Thought specimens of andradite garnets predominate at the locality, some few good specimens of quartz and quartz associated with andradite are produced. The combination specimens of quartz and andradite are really much nicer and more sought after than just the specimens of andradite without associated quartz crystals.

Quartz druse on chalcedony, before cleaning	©

The cleaning process in a case like this is fairly straight forward. High pressure water to clean off as much dirt as possible and then immersing the specimen in a solution of "iron out" or oxalic acid will remove any remaining "iron" staining.

Quartz & Hematite, 6.5cm wide	© Rob Lavinsky

This locality is almost with in a stones throw of the little desert community of Quartzite. During most of the year the place is nearly abandoned and the few locals that live there survive on the few cars that pull off the interstate to get gas or perhaps some hamburgers. In February, the snow birds descend on the area and the populations swells to tens of thousands with camp trailers and mobile homes creating a traffic jam on the single little main street that runs through the little town. They also carpet the desert for miles around to enjoy the giant out door swap meet and Rockhound pow wow. I don't think this tiny mine has produced a good specimen of quartz and hematite in the last 50 years. It has been beaten to death by field collectors for generations. About 50 years ago you could go there and break up quartz boulders on the dump, and if you were lucky you might find a small specimen of bladed hematite and quartz but you had to be real lucky, and even then I never was able to get one as good at the one pictured here nor did I know anyone who ever found anything that good. Some of the old field collectors in Arizona and southern California might have a nice specimen from there that they collected generations ago, but few of them had any as good at the one pictured. The mine also produced specimens of micro Zunyite crystals frozen in matrix.

Quartz v. petrified wood, 12cm wide	© 2003 John H. Betts

There is a region near Holbrook, Arizona that is world famous for its petrified wood. In 1906 a portion of this area was set aside as a National Monument and upgraded to a national park in 1962. It is destination that every mineral collector and rockbound should visit. Big colorfully long and chunks of petrified wood litter the surface in many places and though you might not want to put one in your collection you can't help but be impressed. The petrified wood from this locality can vary in color, but is is famous for its red color with occasional spots of pale green and blue. Some of the logs are huge and can reach two meters in diameter. On some of the ranches that surround the park also have abundant deposits of petrified wood on them but over the years the more easily accessible material has been collected and sold. The most highly desired pieces of wood show the original round shape of the tree trunk or limb and when cut and polished have minimal defects in terms of cracks or holes.The more colorful the better. Some logs have produced beautiful "rounds" of more than a meter in diameter and have been sold for more than $10,000 each. I have been told that some of the logs on the privately owned ranches are so big that they can't be moved and that to be cut, they would have to have a big wire saw built on the sight to cut them down into manageable sizes. Some wonderful tables and desk tops have been made from some of these.

Washington Camp is now a ghost down in southern Arizona and in 1920, probably its high point, had a population of about 5000 people with their economy bases on mining in the area. Since the early 50s the locality has been know to collectors for the broad array of quartz specimens that it produced, many of them from underground. It is probably best know for specimens of Quartz Japan law twins found there, some of them with "ears" as much as 20 cm and perhaps even more. In the early days the locals did know know about Japan law twinning in quartz and all the specimens were more or less equal. Dick Bideaux of Tucson told the story that once when he and his father were visiting the camp, they went into the one little general store where the owner/operator George Gerard was selling quartz specimens from the mine for $2 per pound. Even as a young age, Dick knew what Japan law twins were and they gleefully went thorough his inventory of quartz specimens and picked out all the good ones with Japan law twins. Later George Gerard closed his little general store, moved to Yuma Arizona and became a wholesale mineral dealer, mostly selling flats of cheap tourist rocks to rock shops. Some of the Quartz Japan law twins show quartz crystals twinned multiple times and make for very interesting specimens.

Quartz
Arkansas

Most of the quartz specimens from Arkansas are found in the Ouachita Mountains some of which extend into Oklahoma and some good quartz specimens are found in Oklahoma, but they are not nearly as well known as those from Arkansas. Though the quartz crystals from these localities have been known for more than 100 years it was not till the advent of World War II and the need for quartz radio oscillator plates of untwinned quartz for the control of radio frequencies that the area was heavily investigated for untwinned quartz crystals. Some were produced but the main source of this type of quartz was found in Brazil and hundreds of tons of Brazilian quartz were imported for this purpose and also used to build the US national strategic stock pile of quartz. This stock pile has recently been sold off because suitable quartz can now be grown in large stainless steel autoclaves more economically. The Arkansas deposits occur throughout the thick, deformed Paleozoic shales, sandstones, and cherts exposed along the central belt of the Ouachita Mountains. Steeply dipping fractures closely related to the major folds control the deposition of most quartz. Most of the crystals are transparent only at their tips and grade into translucent to white quartz near their bases. There are also localities for quartz crystals in Hot Spring, Pike, Pope, Pulaski, Sevier and, Yell counties. In Mount Ida (Montgomery County), Ocus Stanley began the modern mining of quartz in 1930 and this is generally considered to be the heart of the quartz country. Ocus Stanely was sort of considered to be the grandfather of quartz specimen dealers in Arkansas.

Most of the quartz crystals found in Arkansas are rather simple hexagonal prismatic quartz with few associated minerals. Sometimes the quartz crystals from there have green inclusions of chlorite group minerals that can produce "green" quartz and quartz crystals with striking green phantoms. Some calcite has been found as well as specimens with little rough crystals of Ankerite. Some quartz specimens can reach more than a meter in diameter and the maximum crystals size may approach a meter in length, but the best specimens are usually much smaller. A few striding specimens exhibiting Japan law twinning have been found and one spectacular specimen recently on display at Tucson may have sold in the six figure range. Probably the finest quartz from Arkansas have been found at the McEarl mine.

Irradiated smoky Quartz, 28cm wide	© 1

The specimen of smoky quartz above is not a natural specimen. It has been exposed to gamma rays and turned a dark smoky black. A certain small percentage of Arkansas quartz specimens is sent to companies that sterilize food by the use of cobalt 60 generated gamma rays to turn the quartz from white to almost a black. Most of the time not very good specimens of quartz is used for this purpose, because collectors frown on treated and "enhanced" specimens and the better grade specimens will bring more in their natural state. A small amount of aluminium in the structure of the quartz that sometimes replaces a small percentage of silicon in the structure allow the radiation to create the smoky color in quartz. The radiation treatment can be controlled to give any degree of smoky color desired but this is rarely done, and the quartz that is treated just gets "blasted" and turned almost black in color.

Quartz, 5.2cm wide	© Joseph A. Freilich

In the 1990s a find of quartz at this locality produced some specimens that many consider to be the worlds best specimen quartz. The crystals were long and prismatic, transparent and exceptionally shiny. Often the striations on the prism faces were spaced just so that they seem to act as diffraction gratings and create subtle rainbow colors along the length of the prisms. Crystals up to about 30 cm were found and brought thousands of dollars each. Collectors as well as the new age people went nuts over these things. I hope some day we may be able to show good pictures of some of these specimens rather tan the nice but comparatively rather sad little specimens shown here.

There are two quartz localities in the Saline valley. The one that produces the Japan law twins is really not down in the valley, but located high up in the the north end of Nelson range of mountains that bracket the Saline valley on its south end. They were found in a little copper prospect by Robert Bartsch of Pasadena California and with the help of Dr. Gary Novak the bulk of the fine specimens were collected. The locality was a skarn deposit that also produces some not very remarkable epidote and garnet specimens. The locality was very steep and down off the crest of the mountain. A wooden platform had to be built so that a few holes for explosives could be drilled. One of the better specimens had two in echelon six inch twins was destroyed during the cleaning process. Fewer than 50 good specimens were collected. The other Saline valley quartz locality produces nice smoky quartz crystals, though mostly as single crystals. This locality is located toward the north end of the valley a bit west of the road. Many of the crystals exhibit good left and right handedness and were abundant enough that several hundred pair were collected and sold to a mineral of the month club. The largest crystal from the find was about 20 cm, but as usual, the better specimens were substantially smaller.

Petersen Mountain actually straddles the state line between California and Nevada and specimens have been found in both states. In the Quartz, USA article that includes Nevada, more pictures are shown. The locality has been dug by generations of collectors and recently in a more organized manner by claim holders. The locality is often called Hallelujah Junction after a wide spot in the road that used to be the location of a small general store. The locality is famous for the fine quartz scepters that are found at the locality, some of which are smoky and some of which are of amethyst.

These specimens look pretty good, but these are exceptional for the locality and most of the specimens the locality has produced are not nearly this good and you usually have to work very hard for what you get. Compared to the tons of better amethyst specimens that are produced annually from the basalts of Roi Grande do Sul, these specimens represent a good recreational outing with lots of hard work for the people who collected them. The localities are represented by some shallow surface workings and probably not be dignified with the name of Mine.

This mine has produced a good quantity of large quartz crystals, most of which have inclusions of pink Montmorillonite. Their virtue is perhaps best displayed when these crystals are cut open and polished. Norm Dawson who operated the mine for many years had a yard full of the crystals. He found that cutting them in half and polishing them provided more financially rewarding than just selling the natural crystals. The mine is much better know for the wonderful morganite Beryl specimens that it produces.

A pegmatite that has been worked on and off for years.

It did produce some few good quartz specimens, but nothing that would make a bishop kick a hole in a stained glass window.

Nebraska is probably the most mineralogically challenged states in the country, perhaps rivaled in its paucity of specimens only by Hawaii or Puerto Rico. These Quartz pseudomorphs after Gypsum are not unique because they are found at other localities, but I thought they were pretty cool and worth of inclusion here in Best Minerals.

Fire opal has been dug at Virgin Valley for at least 100 years and fine examples of it have sold for thousands of dollars. Unfortunately the opal from this locality, thought it is often displays fabulous colors, is not very stable and has the reputation of cracking if left out of water or oil for a long time. Most of the fire opal has been found as replacements of limb casts, but other fossilized material has also been found converted to fire opal. Back in the 1960s there was a well known jeweler/rock shop in the Phoenix, Arizona called Hodson's after the owners name. He owned property or had claims in the Virgin Valley, Nevada area where they periodically mined for fire opal. In the store they had a fairly good size fish tank and in the bottom of the tank on the gravel floor, they kept a number of fist size limb casts of fire opal from their mines. It was a great way to display them and it also helped to preserve them from cracking.

This locality has produced a few crystals of quartz containing inclusions of stibnite, but they are few and far between and never plentiful. Also the crystals are rarely more than an inch or two in length. In some of the crystals, the stibnite has been altered or partially altered to other antimony minerals. At the Bottomley Prospect which may be were the crystal pictured here came from, Scott Klein of Great Basin Minerals spent several days digging a trench .7x5x2 meters and for his trouble recovered "several dozen" quartz crystals between two and three cm long with stibnite and altered stibnite minerals included in clear quartz. That makes for some pretty expensive little quartz crystals. I don't think he has returned to dig there again.

Quartz scepter, largest ~7cm tall	©

Petersen mountain is right on the state line between California and Nevada and fine smoky/amethyst scepters have been found on both sides of the line. The mountain has been dug on by amateur collectors and commercially for a long time. There have been many claims filed on various portions of the mountain and some of the claims like the Crystal Tips No.1 actually is right on the border of California and claim papers have apparently been filed in both states. Currently mining regulations make mining in Nevada more congenial than in California so the two commercial digs that are currently intermittently operating are working on the Nevada side of the mountain. I don't think it really makes any difference to collectors exactly where on the mountain any particular specimen came from, nor is there any practical way of knowing or maintaining the provenance of each specimen. Recently a very fine large scepter was mined that was at least a foot long with a great big fat mostly smoky scepter sitting on a long slender quartz crystal. Some people would murder their grand mother to get their hands on a specimen like that.

A number of quarries in the New Jersey trap rock area produce quartz casts after glauberite and they can be distinguished from anhydrite casts which are quite a bit more common by their diamond shaped cross sections. The ones pictured above are good, but better ones are shown below and some of them even have other minerals growing inside the casts. Good stuff, especially for pseudomorph collectors.

Some consider these to be the best Quartz Japan law twins that the US has produced. They are far from being the largest cut their luster and smoky color which is very unusual for quartz twins sett them apart as something special. Some smoky quartz from the El Capitan mountains is restricted for collecting and at one time, agents from the US Federal government were seen at various mineral shows trying to find out who dug the specimens and even sent agents to a gem and mineral show in Europe to look tor specimens. I suspect that the agents just wanted a vacation trip to Europe.I have a small specimen of smoky quartz crystals from the locality that has a small well formed Allanite crystals growing with the quartz.

The quartz crystals from the Herkimer County region of New York state have been known long before "white men" came to North America and indigenous people who lived in the region. Settlers found them in their fields and in the streams of the area and in time came to be know as Herkimer diamonds after a military officer and whose name was eventually given to the area of what is now Herkimer County, New York. The quartz crystals have been called herkimer diamonds because they are shiny and sparkly look like what the settlers thought a natural diamond might look like, though it is unlikely that any of them had ever seen a natural diamond crystal. Frequently they are doubly terminated and are found in cavities in the local limestone, more correctly dolostone. The region has been the happy hunting ground for field collectors for more than 100 years. Currently all the land in the area is either privately owned or property of the State of New York which frowns upon people digging big holes in their property, people still flock to the area to collect their pretty quartz crystals. There are several places where for a fee you can dig to your hearts content and if you are willing to work like convicts on a rock pile you can still on occasion find fine specimens. Over the years it has become increasingly difficult to find fine specimens, but the people keep coming. Almost all the specimens of crystal clusters that are sold to collectors. Almost all the crystals that are found are found as loose crystals and though at one time they may have grown together, time, the geological processes that take place in the ground and the mining processes act to break the crystal clusters apart and to get nice crystal clusters, the crystals must be carefully fitted back together and glued in place. Almost all the fine clusters of herkimer quartz that are know today have been made by carefully fitting the crystals back to gather. Given the great amount of hard hand labor that is needed to find these things today, there will never be any big quantity of them on the market, and the prices for the find examples of them will always be high. Sometimes the quartz crystals from this region can reach more than six inches in size, these large crystals are always full of cracks and never as perfect as many of the smaller crystals. A perfect transparent doubly terminated undamaged "diamond" of more than an inch is rare, and I don't think I have ever seen one larger than two inches and the ones that are larger than an inch often tend to have a slight smoky color. Sometimes the pockets in the limestone where the crystals are found will produce hundreds of small, many of them the size of rice grains. Although there is not much of a market for them, collectors carefully collect them up and sometimes you will see small glass bottles filled with hundreds or even thousands of these tiny brilliant doubly terminated quartz crystals. I have always wanted one of these bottles, but have never seen one for sale. Sometimes the quartz from this region has little black inclusions of some carbon based material and people have speculated that this may be one of the reasons for the particular brilliance and transparency of the quartz from this locality.

Oklahoma is generally better know for the reddish colored Barite roses rather than its quartz crystals, but part of the same geological formation that produces the wonderful quartz crystals in Arkansas intrudes a bit into Oklahoma and the area produces some surprisingly fine quartz specimen. The big single point shown below is exceptional.

The fire opal from this locality gets much better than the examples we currently have to show you. Some of the best ones can be seen in the Rice museum in Hillsbrough, Oregon.

From the variety of fine quartz specimens that this locality has produced it is easy to understand why is was such a popular collecting site for collectors. The "raspberry" scepters were probably the most sought after specimens that the locality produced, but who could resist the fine Quartz Japan law twins that the locality produced? Some of the specimens pictured here were as good as they got.

The locality is most famous for fine clusters of prismatic Quartz crystals associated with bright shiny cubic pyrite. Some of the quartz showed sceptered ends, and that only increased their appeal. Whole summers were spent by teams of collectors working like trolls often hanging from ropes on the canyon sides in order to work. But when you can collect specimens like this, it is worth it.

Quartz - Australia
SiO₂ trigonal

Here will go the best quartz pictures that we have from Australia and some general comments about the quartz specimens from Australia.There are localities out there with fine specimens that are not even mentioned on mindat. Also in some instances there are sometimes pictures on mindat, of specimens from a locality, but they were so ratty that I did not include them here, but there may also be really good specimens from there that we should talk about in this article.
Any comments or corrections are also welcome.

New South Wales, Clive Co., Torrington, Silent Grove Mine


Quartz, Silent Grove	© Jon Mommers

[info from Jon Mommers] "These were recovered from an old tin mine known as Silent Grove, the geology is representative of the granite-hosted cassiterite deposits found throughout that area. Large groups and thousands of single crystals, upto 40cm long were collected about a decade ago in a commercal operation to recover Cassiterite specimens for the collector market. Some very impressive Cassiterite clusters to 10cm and single to 4cm were recovered on smokey quartz crystals. Silent Grove was a working tin mine and from what I have been able to ascertain was first worked in the early 20th century."

I have a specimen matching this one, labeled Silent Grove Road, Torrington. A good number of these superb crystals were found in about 1998 -1999. As I heard it, contractors were digging a trench for roadworks, when luckily some collectors came by and noticed the crystals, and eventually a big dig ensued. There have been a number of other quartz outcrops producing good specimens in the area exposed following logging and road works.

Quartz, Tambar Springs	© Greg Andrew

This general area is well known for fine stellerite and heulandite. Early on many specimens were labeled Coonabarrabran or Gunnedah, both towns a long way from the main collecting sites. There are at least three principal sites:
Garrawilla Station, Coonabarabran district, Pottinger Co., New South Wales, Australia
Glendowda Station, Tambar Springs, Pottinger Co., New South Wales, Australia
and
Mount Mitchell Station, Tambar Springs, Pottinger Co., New South Wales, Australia.

Specimens are found in large cavities in vesicular basalts with pink stellerite and red heulandite, which sometimes have attractive globular clusters of drusy quartz overgrowing them. A large amount of material has been collected by private collectors and dealers, but most landowners present have banned collecting due to some colectors doing the wrong thing by them.

Hanging Rock is an old gold mining village and also a rock face on the Northern Tablelands, New South Wales, Australia. This former gold mining town is situated about 10 km south east of Nundle. Nundle is noted as one of the best areas in the State for crystals. Some gold and other precious stones to be found include zircons, green jasper, sapphires and serpentine minerals
Nundle was established at the foot of the Great Dividing Range when gold was discovered at “The Hanging Rock” and nearby Swamp Creek in 1852. By June 1852 there were 300 diggers on the fields at Oakenville Creek.[2] . Prospectors from California, Europe and China were also digging along the Peel River and up the mountain slopes.

Quartz, CSA mine	© Martins da Pedra

CSA Mine is an underground copper mine located in Cobar, Central Western NSW. The mine initially started in 1871 with an erratic production history until 1964, when Broken Hill South Ltd began large scale production. The mine passed to CRA in 1980 and then to Golden Shamrock Mines in 1992. The mine was closed in 1997/8 following its acquisition by Ashanti Goldfields and was reopened in 1999 by Glencore.
Since 1965 the mine has extracted substantial quantities of zinc, lead, silver and copper, but today, CSA Mine focuses on mining copper, with a silver co-product.
Good specimens are rarely seen.

Quartz, Blue Hill	© James Tzaferis

The smoky quartz crystals from Blue Hill are found in north/south striking quartz veins cutting metasediments of Ordovician age. The quartz veins are genetically related to fluids from nearby granitic intrusions of Carboniferous age. Although veins up to one meter wide have been found most are between a few centimeters and thirty centimeters. The crystals are retrieved from clay filled vughs which appear randomly within the veins. Gem clear crystals up to fifteen centimeters have been observed and larger ones most probably exist. Although rarer, groups or clusters of crystals have also been collected. [from Mark Rheinberger]

Quartz, Tarana district	© mark Rheinberger

Tarana lies within a narrow section on the eastern side of the Bathurst Batholith. The granites that make up the Bathurst Batholith are mostly barren of mineralization, although Feldspar, Quartz and Clays were mined in the Tarana district. Around Tarana and other areas to the south, Quartz (Amethyst, Smoky) and Feldspar crystals have been found in small gas cavity pegmatite bodies (miarolitic cavities). These cavities are difficult to locate but occur in the granite generally near the margin of the batholith.[From Mark Rheinberger]

The Smoky Quartz crystals range in size from tiny to about half a meter long (to date). Crystals often show signs of multiple episodes of growth and sometimes Amethyst forms last covering the smoky with small amethyst crystals. Amethyst scepters also occur occasionally on the smoky quartz.

This was an important site for collecting amethyst in the 1970’s-1980’s, but I gather the site is nearly worked out now. The actual site was on a neighbouring station, accessed via Corona, but I forget the name now. The collecting focused a on a couple veins with open vughs with generally small crystals to about 1 cm. They range from pale to very deepl coloured.
Some samples are quite green , from bleaching from exposure to the sun (these contain fine inclusions of a green micaceous mineral). Other are smoky to near colourless.

Wave Hill Fossicking Area lies within Wave Hill Station (also known as Kalkarindji ). The Designated Fossicking Area is designated as FA8 on the Northern Territory Government Department of Mines and Energy maps. (http://gemfossicking.com.au/wavehill_station.html)
Gemstones found in the Wave Hill area of Kalkarindji include Prehnite, Smokey Quartz, Agate, Jasper, Amethyst, Citrine crystal and Calcite. Extensive areas around here are under lain by volcanic rocks; these basalts contain geodes which decompose and weather out over time to form hollow lava encrusted boulders with their inner surfaces encrusted with crystals. These can be found either on the surface or buried in the soil. Where the boulder has been broken or decomposed banded red and white agate or quartz crystal remains.

Similar material occurs on nearby Camfield Station.
"Theses sites are in the Wyalong Ranges, south west of Katherine and when you get to Top Springs Roadhouse head south west towards Wave Hill you will see the ranges, that have much basalt and is the place to find Quartz, Agate (mostly pink and white banding) and Prehnite. Much of the amethyst has pit marks but very good examples do exist. [Costas Constantinides ]

Quartz veins in late Proterozoic sandstones in operating and abandoned quarries produced some superb crystallised quartz specimens especially in the 1960’s - 1980’s – maybe still? There were a lot of sites, a couple of the best are the Ashton and White Rock Quarries (see below). Crystals were up to 150mm long, usually glassy to white and sharp but with some clay and/or iron staining needing cleaning. Its not usually easy to pick the exact location of the specimens.

Quartz veins are well exposed on the rocky surface on Philosophers Ridge and near the Iron Blow mine. Although the veins are highly weathered and decomposed, spectacular quartz crystals to 6 cm can be collected, usually lustrous and colourless or milky. Some exhibit fascinating chlorite and haematite inclusions, colouring them variously green, red or black, or rarely smoky or amethystine. Some of the haematitic quartz crystals are sprinkled with small black to blue anatase crystals.
It occurs as lustrous, often spectacular crystals to 50 mm in several varieties: colourless; green (chloritic); red to bluish or black (haematitic); or rarely smoky or amethystine crystals (Day, 2001), as well as a massive, milky gangue mineral. Quartz forms in at least four stages: it is the main matrix and second crystallising phase in vughs in the veins , but it may overgrow later minerals, indicating a spasmodic deposition and forming interesting "phantoms". Some good Japan-law twins and “faden” habits occur. Some exhibit fascinating vermicular chlorite and specular to colloidal haematite inclusions, usually much less than a millimetre in size.

Prince Lyell mine, Queenstown district, Tasmania, Australia

The Mt Lyell copper-gold mines produce some excellent crystallised specimens of quartz, usually with chalcopyrite, haematite, dolomite-ankerite and other minerals, in late stage veins. The deposits are generally considered to be of Cambrian volcanic origin, but the late stage, mineralised but undeformed veins,may be of Devonian age.

The opportunities to collect on the mine leases are infrequent and collecting is discouraged by mine management. However some miners continue to rescue specimens of reasonable quality and these are readily available from some outlets in Queenstown and elsewhere.

http://www.mindat.org/photo-211904.html
The mine is developed on a number of relatively narrow quartz lodes traversing hornfelsed slates of the Ordovician to Early Devonian Mathinna Beds. The lodes are related to an underlying granite, part of the Ben Lomond pluton, of late Devonian age. These granites are responsible for the tin and tungsten mineralisation throughout Tasmania, and some of the gold, copper, silver and lead mines also.

The veins are vuggy and mostly zoned, with a selvage of muscovite-cassiterite-wolframite, overgrown by quartz, topaz, fluorapatite and fluorite, with a central zone of late stage sulphides, haematite, scheelite and carbonates. There may, however, be several generations of some minerals. The wallrocks are hornfelsed, and locally silicified, sericitised and tourmalinised.

Quartz makes up the bulk of the veins, and occurs as good crystals in vughs, from colourless to smokey, amethystine or white in colour.

They are, again like Rosebery, volcanogenic massive Pb-Zn-Fe-Cu sulphide deposits hosted by the Cambrian Mt Read Volcanics. Quartz occurs in lustrous crystals to ~6 centimetres in vughs in both the Que River and Hellyer Mines. Good, small tennantite-tetrahedrite crystals have been found on quartz crystals in the Que River mine (Fig 9).

From Steve Sorrell at crocoite.com:
Mooralla has long been a famous collecting area, mainly in lapidary circles, and is renowned for its spectacular specimens of smoky quartz. Lesser known is the occurrence of other forms of quartz, including epimorphs, and a small number of other minerals.
The popular smoky quartz collecting area of Mooralla, also known variously as Black Range or Anderson’s Creek, is located west of the Grampians in western Victoria near the Rocklands Reservoir. The township of Mooralla consisting mainly of a few buildings, is a few kilometres to the southeast. See Map at MultiMap.com.

Access is via a rough track, which is often difficult to travel on, particularly following bouts of wet weather. The collecting area itself is Victoria’s only? fossicking reserve, and is "looked after" by the Horsham Gem Club members. Fossickers are allowed to camp there, and a toilet facility was erected a number of years ago. Those that have used this facility will attest to the resilient nature of the local flies, who may be trapped for many months, but when the lid is lifted, sound like a jumbo jet taking off as they escape!

The treasured smoky quartz "geodes" that have been highly sought since the 1960s, occur in a decomposing rhyolite, and are sometimes described as miarolitic cavities. Where once good specimens could be extracted from near the surface, holes are now dug down to depths approaching 6 metres in the main part of the field. For those that like smaller specimens, loose crystals, or the other minerals that are occasionally found, shallow holes to about 2 metres deep at the perimeters of the field will fulfill their needs.

Quartz is the dominant mineral found at Mooralla. The most popular, sought after, and aesthetic form, is the so-called Mooralla Crystal (smoky quartz), which may be found as simple or complex crystals, or groups of crystals to many centimetres in length, and rarely as sceptres. Many of these crystals are not simply a dark form of quartz, but exhibit wisp-like curls of smoke that swirl through the crystal. Gas bubbles in liquid inclusions are not uncommon but are difficult to find until you have "got your eye in". Recent editions of both the Mineralogical Record and the UK Journal of Mines and Mineralogy have featured photographs of Mooralla Crystals (although both have misspelt the locality as "Moorella"), and the special publication from the Mineralogical Society of Victoria, Gemstones of Victoria, features a small section on Mooralla.
Loose crystals are common where they have weathered out of the rhyolite. However, deeper down, specimens on matrix can still be collected, but beware. Some crystals that look like they are firmly attached, may come away when the specimen is washed. Even many of the more resilient crystals may show signs of damage to terminations and internal fractures, possibly pointing to some geological activity after they had formed.

Other forms of crystalline quartz include pale lilac amethyst, which is scarce and usually only occurs in small crystals up to about 1cm in length, and small colourless quartz to only a few millimetres which often lines cavities. Rarely, cavities may be filled with banded agate, a cryptocrystalline form of quartz.

Some seven or eight years ago an area measuring 200 x150m was excavated on a pegmatite exposure near Terip Terip, to a depth of about 30m, when pumps could not keep up with the influx of ground waters and work stopped. Dark smoky with good lustre and large gemmy sections were recovered mainly as singles to 50cm, with crystals measuring 20 to 30cm being relatively common. Unfortunately, their recovery was undertaken by a number of well intentioned but inexperienced collectors and the majority of specimens showed significant damage. The largest group I have seen recovered from this deposit measured some 60x 50cm at the base. [Jon Mommers]

No one goes to Mt. Antero to try and dig quartz crystals, they go looking for crystals of aquamarine. If you can't fine aquamarine crystals you are happy to find good Phenacite crystals, but if Quartz specimens are all you can find, well you will take those too. The locality had been prospected and dug on for more than 100 years. Probably the first notable success was Ed Over who was able to dig some good aquamarine crystals that if my memory serves me ended up at Harvard University. He camped down below timber line and each day hiked up a couple of thousand feet to his diggings. The locality is renown for its terrible electrical storms. More than one person told me that they have run down the mountain in fear of their life because of the lightning bolts striking around them. One old timer told me about the time he felt the hair on his head standing up and when he would lift his rock hammer into the air it would hum. This locality will likely never be a big producer.

There are many pegmatites outcropping on both sides of Crystal Creak and in the Crystal peak region and all of them produce quartz crystals of one kind or another. Waling through the hills you can sometimes find quartz crystals laying on the surface of the ground along with pine needles. I found a nice crystal in just this way. The idea in prospecting this area is to find quartz crystals or fragments of quartz crystals in the soil and then track their source uphill till you find the pegmatite they weathered out of and then start digging. The goal is not to find fine smoky quartz crystals,which most of the quartz in this area is, but to find pockets of blue microcline crystals (amazonite) associated with smoky quartz crystals. But, if you can find only good quartz crystals, well you take those instead. Of course if you want to be cruel you scatter a few of them around for the next guy to find and make crazy dreaming of the fine pockets of crystals that they must have come from.

Quartz, ~4cm wide	© Paul Gilmore

The Roncari quarry is a trap rock quarry and periodically the encounter pockets containing fine daotlite, quartz, prehnite and calcite crystals. The quartz crystals are not particularly outstanding, but they are often prismatic unlike their drusy cousins from most of their New Jersey cousins from the Watchung traps. Not many localities produce prismatic quartz with daotlite and prehnite associations, and some of them can make for striking specimens. Many quarries produce good specimen, but unless there is someone there to collect therm, they are all run through the crusher.

This amethyst locality has been known for almost 100 years. It has produced some surprisingly good amethyst specimens and recently one that that was truly astounding. It is pictured above, the first one on the left. A dark purple cluster of amethyst crystals sitting on small snowy white quartz crystals. Even being familiar with the fabulous amethyst specimens from Rio Grande do Sul, Brazil and the Artigas region of Uruguay, this one stopped me in my tracks and made me stare. Now all they need to do is find a few hundred more of them so the price will come down enough so I can afford to buy one.

One one quite knows what to do with them. They are good for gardens and door stops. Collectors will generally not put them in their collections. They have even been used as back drops for little mining tableau's with tiny pewter miners working in their crystalline depths.

The locality has been known for more than 100 years and at one time was mined commercially for faceting grade amethyst, and some of the gems reputedly made their way to the retail establishments of Tiffany's in NY City. As you can see, it also has produced some nice specimens, but for US amethyst, those from Jackson's Crossroads are much better.

Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?

Quartz
SiO₂ trigonal

Here will go a good picture of a quartz specimen from Switzerland and general remarks about the quartz from this country.

Here are some url's to some of the better quartz specimens here on mindat that can be considered for inclusion in the article. These, in mosc cases are just for temporairy use untill we can get images of the much better specimens that are almost certainly out there. We should also consider that there are probably localities out there with fine specimens that are not even mentioned on mindat. Also in some instances there are sometimes pictures on mindat, of specimens from a locality, but they were so ratty that I did not include them here, but there may also be relly good specimens from there that we should talk about in this article.
