According to the fact that fluorite is always one of the most favoured minerals for many collectors, i would like to know what your favourite localities for this mineral are. I know that many of you love this mineral as much as i do and i would like to see where your favourite fluorites are from. When a mineral comes in such quantity and quality from many hundreds or thousands of locations from all over the world, it is hard to pick some special ones, but i think it's worth comparing our favourites. If i had to make a choice of the ten fluorite localities i like the most, i would pick:

- Erongo mountains, Namibia
- Rogerley Mine, England
- Blanchard Mine, New Mexico
- Freiberg, Saxony
- Wölsendorf, Bavaria
- Fluorspar district, Illinois
- Le Burg, France
- Berbes, Spain
- Dal'negorsk, Russia
- Mont Blanc, French Alps
- Nagar, Pakistan

[James Catmur]

To which I would add

La Collada, Spain (especially Josefa Veneros)
Emilio, Spain

Hello Tobias,
You mention a mixture of individual mines and mining districts. For example, the Southern Illinois Fluorspar District had many specimen-producing mines, including the Denton, Minerva #1, Annabel Lee to name a few. On the other hand, the Rogerley is only one of many mines that have produced very good specimens from the North Pennines Orefield, centered on the Weardale region of Northern England.

For obvious reasons, I have a certain fondness for the Rogerley. However, I think the Boltsburn Mine produced by far the most spectacular fluorite specimens to come from the region, and perhaps ranks (in my mind, at least) as one of the world's premiere locations for the mineral. Unfortunately, the mine closed in 1931. Another North Pennines location, the Rotherhope Fell mine also produced some spectacular specimens in the 1920s and 1930s. It's production was nowhere near that of the Boltsburn mine and it remains a relatively known location to collectors outside the UK.

Cheers,
Jesse

An example below of a fine (although not typical) Fluorite from La Collada, Filón Josefa-Veneros, as well as an other example of an unusual Fluorite from Berbes (Coquera del Liso)

Hello Jesse, i know that the district in Illinois consists of many different mines and localities. But i used this imprecise description consciously because i like the fluorites from there generally, no matter if they come from the Annabel Lee Mine or the Minerva Mine. It's the same with the German localities Freiberg and Wölsendorf: Both consist of many different mines and district and produce a lot of different fluorites. And, for example, i like Freiberg fluorites no matter which mine they come from and if they are yellow, orange, green, black or blue ...

Glück auf!
Tobias

Here a fair colored fluorite from the Erongo Mountain with some Muscovite.
Until date Erongo still delivers some of the most amazing and different fluorite finds in Namibia. Pictured specimen is approx. 4x3cm in size / end 2007.

Regards from Namibia

[Namfluro]

Some lovely but different Fluorites from the Erongo Mountains. Great color variety and a different shape to some of the standard fluorites found at Erongo. The 2 pieces fit together perfectly - but were found apart and also bought from different people! :) 6 x 6 cm

Two more fabulous fluorite localities to add to the list:

Obira mine, Japan
Huanzala mine, Peru

[Joan Kureczka]

[Les Presmyk]

By the way, the original list of 10 localities must have been a metric list because there were 11.

I would add the following localities:

Naica, Chihuahua, Mexico
Elmwood mine, Carthage, Tennessee

[Joan Massagué]

I would add:
Chumar Bakhoor, Hunza Valley, Pakistan
Shangbao, Yaogangxian, and Xianghualin, all in Hunan, China

[Montanpark]

Hi all,
i would like to add El Hammam, Taourirt, Oumlaab/Erfoud and Tounfit from Morocco ... i love fluos too (@Tobias: in Germany i like Clara Mine and Rottleberode too),

cheers
Roger

P.S. attached a Okoruso, Namibia fluo

[Tobi]

Hi Roger, Clara Mine is indeed great (not only for fluorites, of course), and the Moroccan localities you mention are also fine, especially El Hamam.

A very good question you posed, Tobias, and obviously one that people were eager to make some comments on. Fluorite is a good mineral for this kind of a question, and obviously, there are a number of aspects about which one can debate, what qualifies the localities to be "the favorite" (color, crystal perfection, abundance, variety, and so on). Thinking about it a while (and peeking at your own list and the other comments), perhaps my own list of 10 could be,

Hardin County, Illinois
Mont Blanc/Chamonix, France
China (various localities!)
Huanzala, Peru
Weardale, Durham, England
Okorusu, Namibia
Berbes, Asturias, Spain
Blanchard mine, Bingham, New Mexico
Riemvasmaak, Northern Cape Province, South Africa
Castleton, Derbyshire, England

It's a cop-out to just say "China", but without consulting references I wouldn't feel qualified to attempt to name (or, to spell!) the numerous good locallities there. And I thought I'd add Derbyshire for its classic occurrence of banded fluorite, even if not known for fine crystals.

I was pleased to see that you, Tobias, had the Blanchard mine on your list, because I would also rate it such, but when one has close proximity and familiarity with a locality, it's hard to be certain if you are judging it objectively, or over-rating it because of your personal interest. For a #11 on my list, another "local" locality that I'd consider, are the occurrences of purple fluorite at Pine Canyon, West Burro Mountains, Grant County, New Mexico.

Cheers, Pete Modreski

At this point, I think that to avoid this thread become chaotic, the best to do would be that someone take charge of it and organize it. I can't do it because currently I'm overwhelmed with my (too) multiple obligations ;-)

Tobias, as you proposed the topic, could you please take charge of it? If yes, please control the evolution of the thread, prepare a list when you suppose that the arrivals of new localities are enough, publish the definitive list and then collect the votes of FMF members. I suggest to use "mp" to send the votes in order don't fill the Forum with the votes of every member, and I also suggest to vote 5 localities in order of priority, then Tobias should just cross the votes to get the final result.

How do you think Tobias? Of course if some other member want to take charge of it or collaborate with Tobias, it would be great. What I'm sure is that at this point we need a "thread capo"! ;-)
