Yes, Yep, Yeah Jason!

You forget always, how old I am.. A more proper answer would have been:
"Thank you for bringing it to my attention, I'll correct it."

I remember that in my active time in the IMCA-board such cases like yours
were the most common complaints filed against members. The solution isn't a
big thing, usually the board commended to the indicted to use those simple
terms:
An "unclassified" in a prominent position and "likely" and "possible".

You know, you have to give to the potential buyer the proper information as
a base for him to make his decision.
Your stones are unclassified according the guidelines of the Meteoritical
Society and the Code of Ethics of the IMCA,
Regarding the latter you have to indicate that.

Whether a collector or buyer concedes to you sufficient experience and
competence to identify your samples by your own correctly, you have simply
to leave to him.

I wouldn't have wrote that, if not already a case had happened, showing that
your advertizing of the possible 7034 pairing can be misleading.
After the fuss in media around NWA 7034 a not yet so experienced German
collector found your offerings and was convinced to get a true part of the
original NWA 7034 stones.

You've to put yourself in the position of the various collectors, not all
are content with the intrinsic properties of the material itself, to some it
adds a lot to such a sample, to print out the articles from the media and to
be able to show his specimen to others while pointing on a photo in these
articles, being able to say, from this very stone my sample was taken from.

Also you will confess, if asked by a collector, which stone he shall choose:
That one from an unnumbered group, not listed in the Bulletin, of a likely
pairing of NWA 2975 at 500$/g or that one from a grouplet officially
classified and with an own number designed at 500$/g,
you'll commend him the latter, as you know the techniques and the customs of
meteorite collecting.

So that collector asked in a forum, what the members would think about your
offer.
(I wished, that someone else than me would have given an answer to him, (but
the others were inert.) cause now I gave the opportunity to a member there
to continue to knit his favourite legend, that the incarnate evil strikes
again to annihilate the world's dealership)

Well and I answered him, that he should ask you again, whether your share
will be officially classified or not.
And told him, that if for him more the material itself is important, he can
buy it, as I rely in your abilities to recognize it, though if he cares for
later swaps, sales ect. that, what I had written in the last posting.
And that's up to him, to decide.
(Another member added an understandable opinion, that if a meteorite costs
10k$ a gram, the collector could expect, that it had been properly
classified).

Btw. meteorites do not travel only in space, but from collection to
collection.
How easily that NWA-numbers you use in your description can later slip on
the label, mislabeling the specimen.

Anyway,
if a classification would make your material more expensive, is not of
interest for a collector
neither whether a material is too common and recognizable for you personally
(an argument which that Jorge could have used too)
He needs only the proper information about the status of the material to be
able to make his decisions.

And anyway,
Whether meaningful or not, these are the rules, which you signed to obey,
when you joined that club of IMCA.

Well in that sense, I think, that club would certainly advise you to change
your advertizing in the manner I explained to you.

Best!
Martin

Hello Martin, All,

No, no, no, and no.

I do not directly refer to the NWA 7034-paired material on my website as NWA
7034. I merely state that it is paired material. In the case of 7034, I
scrutinized even the smallest fragments and volunteered a fragment for
destructive analysis here at school. One of the fragments I received was
not the same material as NWA 7034, and it is set aside. Admittedly, the
sample for work is not 20% of the weight of the lot of fragments. But ,
since I'm not self-assigning an NWA number, the rules have been followed.

"Standard practice" would dictate that I donate 20% of the lot of fragments
to science, which would not necessitate cut samples from every fragment I
have. If I didn't know what I were doing, and donated a ~2 gram fragment
from the ~10 gram lot, most of the smaller pieces *could* be terrestrial
crap, but the meteorite would be analyzed, approved, and you would (I
assume) not be questioning it.

While you may not examine prices carefully, a few weeks ago, the standard
price for NWA 7034 was $20,000-30,000 per gram for pieces less than a half
gram or so. Only pieces in the gram+ range were as little as $10,000 per
gram.

I started my pricing at $10,000 per gram and went down to $5,000 per gram
for larger pieces. My prices were a fraction of the advertised price for
these stones, and unless other dealers have dropped their prices by ~50% or
more, my prices are still lower.

So, yes, my specimens are priced at a fraction of what other specimens are
(or were) priced at. I haven't looked around in the past week or so, but I
assume that's still true. Since I paid just over five times as much per
gram for this material as I have for any other meteorite from NWA, I think
that's fair.

Why donating 20 grams or 20% of the material would enable me to raise prices
by 50% to 300% is beyond my comprehension, though.

I donated a fragment of the NWA 2975 lot to destructive research at UC
Berkeley; it was mechanically destroyed, and the maskelynite crystals were
removed for several Ar dating runs (which did agree with the conclusions
reached by other dating methods for NWA 2975).

Of course, since those stones could also have come from different locations,
in theory, I would need to cut or break each one to confirm it, right? Even
the ones that weigh 0.1-0.2 grams.

By and large, I try to be reasonable with such things. Where do you draw
the line between a large find like Taza or NWA 869 and something like NWA
2975? NWA 801? Each of these meteorites are now examples of large finds
with hundreds, if not thousands, of individuals on the market. As such, I
thought NWA 2975 would be a fine name to use.
Everyone knows it, the stones are easily recognizable, and there is already
much of it in labs waiting to be studied.

http://curator.jsc.nasa.gov/antmet/mmc/NWA2975.pdf

I accurately describe TKW's to the best of my knowledge and describe things
as fully as I can on my website so that there is no potential for
misinformation.

The vast majority of our stones are individually analyzed. The only stones
on the website that have not been analyzed -- yet, that I would be willing
to say have an official number on our website -- are NWA 2975. It's too
common and easily recognizable to bother.

Regards,
Jason
