"there's a large and shiny specimen of massive gold standing in front of it - why should the mirror image of the gold not reflect its colour?"

good point - I was (not clearly) referring to the white quartz. it may indeed be the reflection of the gold specimen. I've sent an email to Ian - will report back.

But concerning the reflection: Of course you're right, tetrahedrite has a silver colour, not a golden one. But there's a large and shiny specimen of massive gold standing in front of it - why should the mirror image of the gold not reflect its colour? ;-)

Tobi, the reflection from the nearby gold might be true, I believe, but the asking price (125k) is simply unbelievable.

something else totally unique - at least to me - I think this is a gemmy tetrahedrite(??) - and priced accordingly. has anyone else seen gemmy tetrahedrite?
No, I've never seen gemmy tetrahedrite and I don't believe it exists. I think the specimen above is "just" very lustrous, but not really gemmy which would mean it is transparent. Nevertheless a breathtaking sample of that great sulfide!

Tobi


Hi Tobi,

You are right, it is not gemmy, but "just" extremely lustrous. :) After seeing it in person, I would say it's the most lustrous tetrahedrite I've ever seen!

PostPosted: Feb 15, 2017 05:23    Post subject: Tucson Show 2017 - A brief note  

A brief note to comment that I will publish much more images and comments in the close future and I'm sure other FMFers will do it too.
The reason of that slight delay is that Tucson is becoming more and more a really crazy Show, very demanding and that consumes all the time available, so only when we return at home we can find time to publish most images / comments.

Add to this the fact that to download the images is very slow in Tucson due the deplorable nets existing there, so now you know why this thread will extend during weeks (or months!)

A good example could be the Gail's thread which now, with her at home is arriving to its usual flying height ;-)

Tomasz Praszkier at Spirifer minerals always has interesting and fairly priced specimens - this year was no different. Here are a few of his newer offerings:
- Unique fluorite specimens from Namibia - hard to describe - see the photos
- Interesting barite - plates and stalagmites from Poland
- Silver minerals - especially polybasite from Fresnillo, MX. Tomek showed me one specimen that clearly displayed lustrous polybasite faces in association with other silver minerals
- Gemmy Fluor apatite from Ontario, Canada - colorful and many double terms
and
- there seemed to be a great deal of wonderful cassiterite from Viloco, Bolivia around the show and Tomek had quite a few excellent pieces. (My thought - the prices in general were remarkably low. I picked up about a dozen pieces at various dealers for prices that I consider as half of previous prices. This may be time to get a good one. Look for gemminess - many display a good bit of clarity.)

Included here also is a new find of Moroccan silvers - these were all etched from the enclosing calcite but some nice xls appeared - mainly dendritic but cubes also.

Good to see the silver minerals from Fresnillo and Morocco. They were available in Tucson - 2017 from a number of dealers with quite a range of quality. I quite enjoyed them.

"To be over the hill"

As in previous years, this year's party was a GREAT success and this success is provoking some "collateral damage" that neither myself, nor Gail & Jim Spann, likes. Due to his fame and the limited number of attendees Casa Vicente can welcome, this year for the first time we decided to set limits and that only those invited could attend. We welcomed those that had responded by accepting the invitation, so that we could know before the party the actual number of invited guests. The system worked well and for the first time we were able to know how many people would attend and get a control of the actual number of guests.

All the guests who RSVP'd loved this new system and there was a nice atmosphere at the party. So, next years party will be a somewhat different guest list. We will not always be inviting the same guests and so we can gather different friends without exceeding the legal number of attendees that can accept Casa Vicente. The Fire Marshall has explicit rules.

Please do not be angry, especially the few who have been left out this year, nor those who may be temporarily out for a year in the future. Either we do it like this or this party will be "over the hill” and that is something that we neither want, nor you, the attendees. 😉

Thanks to Gail for the edits

PostPosted: Feb 26, 2017 08:28    Post subject: Tucson Show 2017 - What's new?  

Barcelona 02/26/2017

In https://www.mineral-forum.com/message-board/viewtopic.php?p=55336#55336 Jordi Fabre wrote:
...This year it seems to have some interesting novelties...

A few days after the end of this year's Tucson extravaganza it is time to now summarize the new discoveries that were seen in Tucson this year. Three of them share the stage and I find it difficult to say which of them has been the most important but in my personal opinion I would put them in this order:

    • Djurleites-Chalcocites intergrowth from the mining area of Aït Ahmane. A couple of years ago we talked about this mineral that was first seen in Ste. Marie 2015 (Sainte Marie-aux-Mines Show 2015 - What's new?) but at that time the determination of the species was still imprecise and, above all, the quality of the specimens was too basic to consider them potentially interesting. Christophe Gobin believed in them more than anyone and was concerned with analyzing multiple samples in different laboratories until he was sure of exactly what they were, and also for two years he was concerned with trying to obtain the best possible specimens. Knowing how Morocco is, it could be called "miraculous" ;-) that he managed, as he did, to keep the subject in the dark, but he was successful and in Tucson presented the result of his efforts. Crystals of more than 5 cm of Djurleites-Chalcocites intergrowth on or without matrix that disappeared at the speed of light ;-). We all had in our retina the best specimen, a piece about 15 cm, coated with crystals of about 4 cm. with skeletal habit and with very good brightness and definition. A "wow"


    • A mine whose name I still do not know and located in East Ujimqin, Autonomous Region of Inner Mongolia, China, which for some months has been giving a very interesting material that has gone completely unnoticed because voluntarily or involuntarily it has been confused with material coming from the well-known mines of Huanggang (located about 800 km from this "new" mine). This mine is giving very beautiful associations of Hematite, variety iron rose, on Quartz and also large and very long white or reddish quartz (due to inclusions of iron oxides) with multiple crystals of some sulfide that I dare not say if it is Tetrahedrite-Tennantite, Sphalerite or Stannite (or even some other species…) partially coated by Pyrite or Chalcopyrite and associated with Calcites and Siderites. It is a very promising mine and if so far it has not been better known that has been because of the confusion with Huanggang. This had already happened previously with the Rhodonites and Tremolites of the Chaobuleng mine, also in Eastern Ujimqin and with the Borcarites, Pentahydroborites and Olshanskyites of the Shijiangshan mine that were also attributed to Huanggang, so we should not discard new and interesting finds in this remote part of the world that seems to be very prolific and varied beyond the famous Huanggang mines.


    • The Palmarejo mine in the municipality of Chínipas, Chihuahua, Mexico that had previously given some good Calcite, has surprised us this Tucson with huge pieces of large crystals of twinned Calcite, coated with a VERY white material that does not appear to be Calcite and with a second generation of crystals also of Calcite. The pieces are monumental and very decorative so they became sought after when they came to the light. It seems that the pocket in which they were found, discovered in October 2016, was as large as a truck so we do not discard the hope that in the future we can see more samples, although it is also true that in the great majority of samples the second generation of Calcite have brownish inclusions that makes them less aesthetic.
      In addition to this, in Palmarejo they also recently found a very curious mix of Rhodochrosite, Kutnohorite and pink Calcite, very aesthetic that if they continue to comes out I am sure that they will be generate interest among collectors. As I found unusual the presence of Rhodochrosite-Kutnohorite in this mine that for me was a classic polymetallic deposit and not so diverse I asked "professor" Peter Megaw and he told me that in fact Palmarejo is a very diverse mine and that in some way is similar to the mines of Guanajuato, even in the presence of silver, so we do not discard that Palmarejo can surprise us again.

Not everything in Tucson was limited to these three major novelties, there were some more novelties such as good: Coppers found in 2015 in the Acari mine in the province of Caraveli, Arequipa, Peru, from where we already knew pretty Chrysocolla but not (as far as I know) coppers. Also are the results of the research that are being done in the well known mine of Los Lamentos, Mexico where until now they had found Wulfenites that are different from the classic ones there, but of average quality and in this Tucson I already began to see some piece of great quality with large crystals and quite transparent. Then, from some place of Sonora, Mexico (secret for the moment), were seen some very promising Wulfenites that perhaps could be of quality in the near future. Another outstanding novelty was produced in the Mont St. Hilaire, Canada, where in November of 2016 it was found a few extraordinary Rhodochrosites, with similar quality of the best Rhodochrosites from other localities and that by its size and intense color far exceed the Rhodochrosites that were found there in August 2015.
Add to this a new locality in Venezuela, in the zone of the village of El Paují in Santa Elena de Uairen, that is giving extraordinarily defined hexahedral crystals of Gold. Plus the showy Chinese Fluorites of the Shizhuyuan mine in Hunan. Add to that in the Tamdrost Mine, Morocco, in addition to the large number of Silvers found they start to find Allargentum and Dyscrasite, similar to those of Bouismas, and also add the two novelties mentioned by John Veevaert in his always interesting chronicles Show Reports, large crystals of Bertrandite from the Golconda mine and Talcs from Lungau, Austria and with all this we can see that this year has been considerably better than previous years in terms of novelties.
But there are also two new "secret" novelties that we cannot talk about yet (shhhhhh ;-), Antlerites from Mexico and Cronstedtites from Morocco...

So without doubt: thank you Tucson for showing us this year so many good minerals, together with a good number of new discoveries that brightens our view! ;-)


More to come…

PostPosted: Feb 27, 2017 16:36    Post subject: Re: Tucson Show 2017  

I debated whether to add this reply onto the 2017 Tucson thread or start a new somewhat related topic, but here goes. And my reply is meant to be direct, thought provoking and even perhaps a bit brutal.

I have been to Tucson 5 times in the past 12 years, but not this past one despite it being on Midwest minerals and having one of my specimens displayed as part of the Indiana State Museum case. Why I did not go, I question myself, but I made the decision not to travel alone and no one wanted to go out there with me this year. So, I have been following all the pix and while they are quite interesting, I find that all the unidentified folks are as unrewarding as looking at and maybe buying unlabeled mineral specimens. Unidentified people, like unlabeled mineral specimens are both no-nos!

The pix also show part of another looming problem. Many of us collectors are getting up there in age. Sure there are youngsters and younger adult collectors, but going to regional and especially national shows and looking at the pix of the attendees at these regional and national shows, shows many collectors well over 65, even into their later 70s, and older. I am almost 74 now and traveling less. I suspect within a few short years there will be a lot of us older folks no longer traveling to the shows. Will we be replaced by a newer younger crowd in the same numbers as previously??? Who knows!

The attendance at the big US national shows has, over the past several years, also shown a significant decline. This includes this year's Tucson show. This was even mentioned as part of the Collector's Edge online summary of the show. The Spann's, especially Gail, is very enthusiastic making each show seem like all is "wine and roses", but unfortunately it is not. She does need to keep it up as enthusiasm generates more enthusiasm!
As to sales, there are always dealers who do well and some who do not. This is a complex interplay of the economy, the specific dealer's merchandise and the prices etc. Hi end dealers, with their clientele and the right specimens seem to do okay; there will always be hi end collectors buying hi end collectibles of whatever they collect, but many middle range and lower end dealers are having problems as travel expenses rise, specimen prices rise and attendance falls off with the aging collector base. Some of these dealers seem saddled with flat after flat of more common mid-range stuff in unending abundance. Certainly different than collecting coins or stamps; maybe a turn off for some collectors to see ALL the specimens available.

Today younger collectors have their time taken up by other interests and fewer collecting sites to help get them interested and keep up their interest. This is, in part, reflected by the continued decline in circulation of mineral related periodicals. I receive the periodicals Rocks and Minerals and The Mineralogical Record. I have received them for 25 years now. Over the past several years, I have reviewed the year end paid circulation figures which are required to be available at the end of each year. For R&M 2015 (vol 90/6) was 5242 copies and 2016 (91/6) was 4508. For MR, a heavily endowed higher end periodical, 2015 (vol 46/6) there were 4791 paid copies distributed. For 2016 (vol 48/1) the total paid circulation was 4064.
Both periodicals have shown declining readerships in recent years. Maybe a reflection of less interested collectors including the younger ones for R&M???

Much more could be said. All that I have mentioned needs be openly discussed and addressed if our hobby, from the highest end collector to the routine collector base is to maintain and flourish in the upcoming years. BOB

PostPosted: Feb 27, 2017 20:15    Post subject: Re: Tucson Show 2017  

Hi Bob, You've raised some good points here. While I really appreciate our regular and tireless reporters who keep us posted on Tucson and other shows, it is frustrating to see so many photos of unidentified people and specimens. Better to have one good photo of somebody who is named, than half a dozen or more virtually identical pics that could almost make a video if you strung them together.

I can usually spot a few old friends among the party crowds in the show reports, but many remain unrecognized, and I suspect the problem is worse for beginning collectors and readers in other countries.

The preponderance of older people in the hobby (and I'm one of them!) is getting alarming, but I wonder if some of this impression is because FMF and other websites focus on the high end shows, where the biggest budgets meet the best rocks. How about all those many other shows around Tucson? Do they attract younger collectors, or just more geezers who happen to prefer beads and agates?

Regardless, I hope the situation doesn't result in continued circulation declines for our leading mineral magazines. We are fortunate in the U.S. to have journals like Min Record and Rocks & Minerals, of such high quality and frequent publication!

If these comments are meant for me I would like to respond. I did not intend for most of these photos to be posted. I did not want most of these photos to be posted. Actually, after I found that they had already been posted, I tried to provide names and descriptions, but gave up in frustration after having done the first batch. As indicated at the beginning of the second group these are mostly close friends and even identifying them would mean little to nearly all FMFers. I agree with Bob Harman that unidentified people in photos are not really very interesting. All I can say in this case is I apologize. I didn't even know how to delete them.

No problem, John! I was giving my impression of general Tucson photo coverage in recent years, in the hope of making it more informative for all readers. Rock on!

I agree. All fixed, please see: https://www.mineral-forum.com/message-board/viewtopic.php?p=55916#55916

Great news for me to read these comments because it takes a lot of time take the photos, process the photos, make a choice on photos of others, delete with Photoshop the dates in the photos when them appear, publish them, search for the right names, don't do typos or mistakes on these names and even publish good photos of minerals to satisfy everybody. So, as unfortunately in general I do not have much time available, from now I will publish the posts I really like to publish and, as usual, I will try to do it in the best, proper way I can.

Thanks to everybody.
