[meteorite-list] AD:Special NWA 4901 a pair of the oncemostexpensive NWA ever

[Jerry]

Cool Martin, guess membership in this list does pay dividends. I learned 
something.
Wonder with all the "tossing around" this meteorite's history involved, 
whether the QUARTZ showed signs of "Shock"?

Yes it is - normally if you're able to identify quartz on a suspected stone,
you can throw it away, as it's no meteorite.
But in a very few, of course as you mentioned in very small amounts, quartz
is found - e.g. in some Martian basalts, NWa 856 for instance (if I remember
right) has some.

Thanks Martin for the reference and the link. I know t is only trace, the I
find the presence of quartz interesting.
Is not this highly unusual for any meteorite?

Dear collectors,

our Special deals this weak with a true legend of the still young history of
NWA-meteorites.

With NWA 4901 as a pairing of NWA 011
we want to let you participate in that material,
which already found his place among the most famous meteorites in the annals
of meteoritics.

The senior collectors will well remember the enormous shake, NWA 011
provoked in the world of scientists and in the collectors community
likewise; the initial debates about its possible origin from Mercury, the
distribution of the material and so on.
Little shavings sold at 100$ per milligram, making that material to the most
expensive NWA ever and the 4th most expensive meteorite - after Calcalong
Creek and the very early DaG 400 and 262 - in history.

It would be foolhardy if we would try to delineate the astounding
particularities and circumstances about that meteorite
in a detailed manner here, as it never could rival the excellent write-up
about NWA 011 on David Weir's page.
(who surprisingly is still not yet awarded with the IMCA Gold Medal for the
excellent service, that he's supplying for many years to scientists and
collectors with his fabulous Meteorite Studies Site!).
Therefore we set here the link:
http://www.meteoritestudies.com/protected_NWA011.HTM

There you'll find all results of the analyses of NWA 011, the
interpretation, its complex genesis and thermal history, the supposed
origin, but also its turbulent human reception here down on Earth.

Perhaps in a short form: NWA 4901 has eucritic characteristics, but is a
basalt, stemming from an other former large parent body than Vesta.

Well, and beside the manmade uproar - NWA 4901 with it's leopardizing
interchange of transparent and opaque crystals..
that meteorite is one of the most eye-appealing and beautiful stones of all
in our opinion!
And we are sure, that many collectors, who already own a specimen from the
pairing-group will fully agree.

We decided to set up for sale a couple of budget-sized slices and priced
them at a irresistible 180$/g.
