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?


Canada produces a wide variety of excellent quartz specimens including amethyst, smoky quartz, water-clear rock crystal, and red hematite stained crystals. Lots of habits, forms, and interesting growth features are encountered. Certainly there is plenty to satisfy the quartz collector. The article below highlights some of the more interesting localities.

QuartzCanadaBritish Columbia, Greenwood Mining Division, Grand Forms, Rock Candy Mine

Drusy quartz on fluorite, 12.5 cm
Drusy quartz on fluorite, 10.6 cm

Originally a fluorspar-silica mine. Now a commercial specimen operation and fee dig.

QuartzCanadaBritish Columbia, Slocan Mining Division, Riondel, Blue Bell Mine

6.4 cm

Produced fantastic plates of slender opaque white crystals (to over 15 cm long) associated with well-crystallized sulphides.

QuartzCanadaNova Scotia, Kings Co., Bay of Fundy

Crystals to 4 mm

Specimens are from basalt cliffs and slides. They often have zeolite crystals (heulandite, gmelinite, etc) on the amethyst. Localities include Amethyst Cove and Halls Harbour where a large find of amethyst was found in a farmer's field and collected by Eldon George in the 1970s(?). Nice specimens with good color are sometimes found on the beach. At Ross Creek, there is a small exposed of limestone that sits on the basalt. Here amethyst and smoky quartz are sometimes found lining agatized fossil tree branches.

QuartzCanadaNova Scotia, Guysborough Co., Boylston Quarry

A former roadfill quarry. Attractive orange and red hematite stained crystals have been found. Many are floaters, tabular and/or Fadens. Green chloritized crystals are also found.

QuartzCanadaNova Scotia, Halifax Co., Bayer's Lake Pegmatite

A business park. When it was expanded (and also when an adjacent highway was twinned) some nice dark smoky quartz crystals were found.

QuartzCanadaOntario, Carleton Co., Osgoode Township, Greely, Grant Quarry

Quarry in limestone which yielded very good specimens of short, doubly-terminated quartz and smoky quartz crystals to over 8 cm on matrix with calcite and dolomite crystals. The smoky colour of the quartz is created by hydrocarbon inclusions.
Collecting status: no collecting permitted.

QuartzCanadaOntario, Carleton Co., Osgoode Township, Greely, Greely Quartz Occurrence

Crystals to 3 cm

Series of diggings having yielded specimens similar to those from Grant Quarry. The quartz crystals can be both clear and smoky. Collecting status: no collecting permitted.

QuartzCanadaOntario, Leeds and Grenville Co., Rear of Leeds and Lansdowne Township, Lyndhurst, Steele Mine

16.1 cm

A mine and many prospects worked/explored for transparent quartz during WWII. Crystals are usually dull white, translucent to opaque. Milky 'phantoms', hematite and chlorite inclusions are not uncommon. Some crystals recovered were fairly large. A similar occurrence exists (crystals are smaller) called the Marble Rock quarry near Gananoque. This locality needs to be combined with .

QuartzCanadaOntario, Nipissing District, Temagami Township, Sherman Mine

Magnetite and jasper, 14 cm

Banded iron formation.

QuartzCanadaOntario, Rainy River District, Hutchinson Township, Atikokan

5.6 x 5.2 x 3.9 cm
3.8 x 1.9 x 1.9

An iron mining district.

QuartzCanadaOntario, Thunder Bay District

A region famous for its many amethyst occurrences. Many of them were exposed during exploration work for silver. The area is best known for its dark red hematite-included amethyst crystals. Occasionally, they are associated with green fluorite cubes and pyrite. Specific localities include the Old Ontario Gem Mine, Normanite Mine, Blue Point Amethyst Mine, Diamond Willow Mine, Purple Haze Mine and Mt Baldy.

QuartzCanadaQuébec, Gatineau Co., Hull Township, Highway 5 Extension
5 cm long crystal

A series of recent road cuttings that temporarily exposed, among other things, calcite veins containing rounded white and smoky quartz crystals. Most crystals were very heavily rounded, thus not noteworthy. Some of the larger crystals, ones to 5 cm, were decently formed. In a few areas, small (usually under 15 mm) transparent, very sharp crystals were found in vugs in massive calcite veins. Most (if not all) occurrences are now defunct.

QuartzCanadaQuébec, Jacques Cartier Co., Montréal, St. Michel District, Francon quarry

FOV 2.2 mm

QuartzCanadaQuébec, Rouville Co., Mont Saint-Hilaire, Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry)

2.1 x 1.5 x 1.0 cm

Black quartz crystals to over 15 cm have been found at Poudrette. Some specimens were associated with gaidonnayite.

QuartzCanadaQuébec, Windsor (Richmond), Autoroute 55 roadcuts

Chamosite included, 19 mm

Alpine veins exposed on several road cuts locally known for fantastic transparent quartz crystals, sometimes included by chlorites, to over 8 cm.

QuartzCanadaQuébec, Capitale-Nationale, Agglomération de Québec, Cap Diamant

The Cap Diamant is the most important geographic feature of Quebec city and when Jacques-Cartier visited Quebec (3rd trip) in 1541, he found numerous small quartz crystals in the cliffs and thought that these were diamonds. Hense the expression "as false as Canadian diamonds" (not so true now, since the discovery of diamonds in NWT, northern Quebec and Ontario). The Cap Diamant quartz can reach up to 5 cm, are for the most really clear, some with skeletal habit and sometimes with water and gazeous inclusions. Other quarries in similar geological formations in the appalachian region have produced similar quartz.

QuartzCanadaQuébec, Estrie, Frontenac Co.,Le Granit RCM, Saint-Ludger, Baskatong Quartz Mine

An exhausted and abandoned quartz mine that exploited a huge circular pod of massive quartz ~200 m in diameter. The mine operated in the 1980s and 1990s by 2000 it was abandoned. The circular pit has nearly vertical walls and is now water filled. During the mining operations some crystal lined cavities with colorless crystals up to 20 cm were found. Minerals found on the dumps indicate the presence of Alpine-type veins and clefts.

QuartzCanadaQuébec, Estrie, Le Val-Saint-François RCM, Bonsecours (Lawrenceville), Mine Cristal (Adams farm)

Superb transparent and lustrous quartz crystals were recovered at this location. Larger crystals, usually clouded, can reach 10 cm in diameter. In the 1970s the locality was worked by Mr. Adams. He used a hydraulic mining method, pumping water from a small pond and using a hose to wash away the soil . The occurrence has been converted into a small mine that supplies a metaphysics shop on the same property. Collecting is limited and permission may be obtained on select dates by Mines Cristal Quebec.

QuartzCanadaQuébec, Montérégie, Les Jardins-de-Napierville RCM, Sainte-Clotilde-de-Châteauguay, Sainte-Clotilde-de-Châteauguay quarry (Marcil quarry)

Produced some very nice, short, doubly-terminated quartz crystals. Several specimens of amethyst were also found at this location.

how do you add hyperlinks to words in your posts? Seems it doesn't like html commands.

Rock Currier March 25, 2009 01:06AM
I am amazed that you have jumped in and done as much as you have. I guess that you wan't to take the article on Canadian quartz in hand.

Here is the information you need.
2. Linking text to images.
Note that in the article above on aluminium that there are images that can be brought fourth by clicking on the selected number after Picture, Like Picture one two etc. They look like this: Picture one. To make this happen you will need to write a tiny bit of code which looks like this < url=>< /url>. It won't look exactly like this because I have inserted an uneeded space before url= and /url which you will not do. Next you will need to type in the text between the brackets that you want to link to your text. In the case above, the code string will now look like this < url=>one< /url>. Next you will select from the Mindat photo gallery the image you want to link to your text. Click on the thumbnail image of the one you want and a large image of it will appear in a separate window. At the top of the window is a field that will contain the URL that you will need to insert into your code string to make the link. In the case above where "one is linked to that particular aluminum image, the URL is: http :// To make this url appear here in this form I had to add an extra space after the http. The final step to linking your text to the image is to insert the URL after the equal sign in the code string which will finally look like this: < url=>one< /url>, but without the extra space before url and /url. When you post your article or save the changes on a reedit of your article, you won't see the code at all, but only your selected text in blue. Clicking on the blue text will open the linked image.

If you will read what is at you will find more about the formatting of these articles and suggestions on how to work better. Ill check back in with you from time to time. Let me know when you want the red ink to start.

Ok. I'll get back to it as soon as possible.

First post here on mindat, but I think I can contribute positively on this subject. I'm specializing in Quebec minerals, particularly minerals from the applachian geological region. In my collection, I have some interesting quartzes from the following localities in Quebec :

- Highway 55
- Saint-Pierre-de-Broughton
- Mont Saint-Hilaire
- Bonsecours
- Carriere Calway
- Asbestos and Black Lake

For now, some of the specimens of quartz are posted on my personal website (see

Almost all of these photos need to be redone, if time permits, I can do some within a week or so.

Salut Francois,

That would be great! The Bonsecours locality is the 'Adams Farm', I will include the new mine's name when I update the post (which I will do as soon as possible, have been busy writing other things).

Another noteworthy locality is the Baskatong Quartz mine in St-Ludger. Have you any specimens from there as well?


Woodrow Thompson April 03, 2009 01:21PM
Hello Philippe and Francois,

The Lawrenceville/Bonsecours/Adams Farm locality is the "Mine Cristal Québec" tourist attraction. I have been there, but they do not permit much collecting. People have told me that some of the "local" quartz specimens in their shop are actually from other parts of the world. Is that true?

Nice web site, Francois! Thank you for bringing it to our attention.

I have not heard anything regarding that. A little info bit: When I spoke to collectors who visited the mine, they said that it had cost 100$ up front and they had to pay extra for the specimens they collected. The tour guide apparently judges what you should pay for them. The tour guides could also limit what the collectors kept.

Having seen specimens from before their commercial venture, I can guarantee that the locality has at least at one time produced true nice specimens.

Francois Letourneau April 03, 2009 09:15PM
Philippe, Woodrow,

Regarding the Mine Cristal Quebec quartz occurence...

I will not enter in the debate regarding where the quartz come from in the mine boutique. What I can say for sure is

-1 As mentioned by Philippe, many very fine specimens of quartz were discovered from this location before it turned out as a commercial exploitation. Some of these specimens can be seen in local museums.

-2 It is possible to visit the mine in a guided tour during the summer months. When I did this activity, I was able to take a look to some cavities in massive quartz where you clearly see large quartz crystals in the vugs. Some of them reach almost 10 cm. Due to iron oxydes present in the water that flows on the crystals, many of them are coated by brown stain. No collecting is allowed during these tours. There is a "metaphysical" part during the visit, the geological part is only 10-15 minutes in the 1 hour tour.

-3 Once a year, there is a one day field trip to the mine where you can dig for your crystals (I don't know if it is still ongoing). Philippe is right again, when I did this activity, I had to pay 80-100$ (don't remember the exact cost) and had to pay to keep few specimens amongst the ones I discovered. I opened a few small vugs and extracted many quartz specimens, the largest one reached a good 8 cm. Clearly, there are still nice specimens to be found there, but the owners are doing so at their own pace...

Let's get back to the article topic.

Regarding the Baskatong quartz mine, I have also specimens from this locality. They are quite large and not really clear. I'll take some photos for reference purposes.

I think we should mention the Cap Diamant (Cape Diamond) quartz in the article. The Cap Diamant is the most important geographic feature of Quebec city and when Jacques-Cartier visited Quebec (3rd trip) in 1541, he found numerous small quartz crystals in the cliffs and thought that these were diamonds. Hense the expression "as false as Canadian diamonds" (not so true now, since the discovery of diamonds in NWT, northern Quebec and Ontario). The Cap Diamant quartz can reach up to 5 cm, are for the most really clear, some with skeletal habit and sometimes with water and gazeous inclusions. Other quarries in similar geological formations in the appalachian region have produced similar quartz.

Rock Currier April 03, 2009 09:22PM
You are getting lots of good suggestions. Don't get discouraged. Just evaluate them all slowly and carefully and ask further questions if you need and incorporate them into the article. There will hopefully be many other people that will chime in with other good suggestions and each one will help make the article stronger. When someone chips in with some well written bit of information you may want to just copy it as is and place it in the article, with appropriate credit of course.

I have just rewritten the introductory remarks to the Best Minerals section that include a new section of the format that we are currently using and advice to authors. If you get time you may want to read them over. If you find errors or have questions, please get back to me.

Hi Woody & Philippe,

I have heard the story from several people that the "metaphysical" quartz being sold at "Mine Cristal Québec" is mostly Brazilian. It is possible that the deposit was exhausted. However, this is still a major Québec quartz locality, or at least it was for many years. I have first visited the Adams farm in 1974 when Mr. Adams was mining the quartz which was in the soil, probably from one or more collapsed (by tectonic movement) Alpine type vein. He used a hydraulic mining method, pumping water from a small pond and using a hose to wash away the soil, which he demonstrated to us. We bought 8-10 pieces from him mostly single crystals. The largest crystal in our collection is 16x7.5x7 cm, but there were much bigger ones available. Many of the crystals had some natural damage, and many had evidence of rehealing. We still have about 10 specimens in our collection and there are many in local (Québec) collections. There is at least one very good specimen at the CMN. I last visited the place 3 years ago, but it was closed. I have GPS coordinates and I am actually surprised that I have not input this locality in MINDAT.
Philippe if you want to do the input here are the coordinates: 45º26'38"N; 72º16'56"W.
St-Ludger was a major quartz locality, but unfortunately by the time I managed to visit, the huge quartz pod was mined out and the pit was water-filled. The dump material is pretty well beaten up but there must have been fantastic specimens there.

One of my minor interests is Québec quartz localities, especially in the Eastern Towships (Estrie).

Thanks Francois and Laszlo!

I did a small update, more to come and I have to research a few localities. This will come probably in early may when some of my mineral projects are done. If anyone can beat me to it, please do!

Woodrow Thompson April 04, 2009 02:29PM
Hi Francois, Laszlo, and Philippe,

Thanks for your interesting comments on the Adams Farm quartz locality. From everything I've heard, it's an important addition to the Best Canada Quartz gallery! I first became aware of this locality many years ago when I purchased a quartz crystal in a Quebec City gift shop, which almost centainly came from Adams Farm. It has amazing clarity and brilliance. When I went to the present Mine Cristal Quebec with Ernie Schlichter and others, we obtained specimens directly from the owner. The crystal groups have a little interstitial graphite, which I think we also saw in the in-situ pockets when we got a tour of the pit. Perhaps this graphite is an indicator that will help people to verify the location for some of the specimens from here??

There are also some nice quartz crystals in one of the asbestos mines at Thetford Mines, whiich were being sold at the local mineral museum. This greatly surprised me because I wouldn't have expected them in the ophiolite district. Probably you know of the locality, but I will send details later this weekend.

Hi Woody,
The Quebec City gift shop was the major distributor of Adams farm quartz for many years.

There are quartz veins in the Jeffrey mine with excellent smoky crystals up to 12 x 7 cm. See photos of specimens in Mineralien Welt 2009/1, although some captions have been screwed up as to ownership. This article (by Horvath & Spertini) presents the latest updated mineralogy of JM that will surprise you.

There are also good quartz specimens at Mine Lac d'Amiante at Black Lake and other asbestos mines in the area. I suspect that there are Alpine type veins in the Black Lake - Thetford Mines area in the asbestos mines, but nobody bothered looking.

Woodrow Thompson April 06, 2009 09:32PM
Hi Laszlo,

The quartz locality that I was thinking of is the British Canadian Mine in Black Lake. I have a couple of specimens from there with colorless transparent crystals to ~ 8 cm long. There is no matrix, but as you suggested, they most likely came from some kind of alpine vein.

Is Mineralien Welt available through any English speaking distributor? My German is even worse (by far) than my French! I spotted the issue with your article on the M. W. website, but couldn't understand enough of the instructions to place an order.

The Sundstorm locality is a prospect that was explored for uranium mineralization in 1957 (if my memory serves well). That is really as much information as i have along with what is on the locality page and that is from a Donald F. Hewitt publication.

The orange Barite is diagnostic for the amethyst specimens from some localities in the Thunder Bay amethyst mining area. I collected this stuff with my kids many years ago at the Dorion mine, but it could probably be from any of several nearby localities. On the way in we saw a pure white epilobium in a road side patch of usual large pink ones. I never saw that again.
See this thread.

I'm in Toronto. I feel the need to go out and find some crystals in Northern Ontario. Can someone please share with me where I should go prospecting, being totally new to this. And what tools do I need? My wife and young kids would have to tag along, so are there facilities where they can feel comfortable while having the experience of prospecting for crystals and gold?
Rock Currier December 01, 2011 08:09PM
Hello Newbie,
You need to put your request in the Collecting forum on the message board and not here in Best Minerals. No big deal, but let me also give you a bit of advice that may be useful to you and make your request to the members on Mindat more productive. You should sign up with your real name on mindat. If you use a "street name" a lot of people here will think you have something to hide. Also, many of the good localities to collect at are not freely given out. The reason for this is that if they are, hoards of people descend on the place and trash it out and piss off the land owners royally. So the people that know about them are not about to hand this information so someone who they don't even know who they are talking to. To find the really good localities you will need to develop a personal relationship with some of the old timers in your area who know where they are. Once they come to trust you, they will likely be much more fourth coming about good places to dig.
