Dear List Members,

I announced a 'most intriguing' New Ungrouped Achondrite earlier this
morning, Northwest Africa 6704. Please find below a listing of what is
currently available. Concerning pricing, I asked a few people what they
thought this meteorite should be priced at considering the special
characteristics it holds;
1) Ungrouped and Scientifically important.
2) Numerous bubble trains that are currently under analysis to see if there
is still any gases trapped within some.
3) Very fresh and attractive matrix.
4) Rare minerals such as Awaruite and Very High nickel content in the metal

A price range of $100-150.00 per gram was suggested for polished slices but
I decided I wanted to offer NWA 6704 at a deeply discounted price to List
Members. I will be offering it for less than half that amount for my initial
public offering here. If future analysis identifies trapped gases or even
'atmosphere' from the parent body, you can be sure I will be raising prices
in the future. Along with the steeply discounted Special price, I am also
going to include a Free Gift that you will see at the end of the specimen
list below.

NWA 6704 has a very dense matrix which polishes to a high luster, making for
a very collectible meteorite. After cutting, polishing, providing type
samples and preserving the majority in a single main mass, there is a
limited amount available to collectors and museums. Each professionally
prepared specimen comes with a color ID card from The Hup? Collection and
will be shipped in a plastic display case, Riker-style box or Gem Jar,
depending on size of specimen, larger fragments will be shipped without
display case.

Original Announcement>>
Dear List Members,

Over the last four months I have been reorganizing my company to make things
easier for me in order to better serve the meteorite community. To start my
official Grand Re-Opening, I have the honor and privilege to introduce to

Northwest Africa 6704...
...a 'most intriguing' New Ungrouped Achondrite.

NWA 6704 is a most intriguing meteorite unlike any others known to man! Not
only does it have tremendous scientific value, it is one of the most
visually appealing meteorites with its dazzling display of yellowish-green
orthopyroxene crystals containing small grains of olivine and chromite
surrounded by large intercumulus grains of albite enclosing small grains of
awaruite (a rare very nickel-rich metal alloy). Oxygen isotope results plot
this achondrite within the field for acapulcoites-lodranites, but that is
where any comparison stops. NWA 6704 is unlike any other meteorite! If that
isn?t enough, this incredible meteorite contains an abundance of ?bubble
trains? within the orthopyroxene which appear to be devoid of fluid upon
initial inspection. Ongoing analyses are currently being performed to
measure the cosmogenic noble gases to determine its CRE age (time spent in
space) and to possibly detect trapped gases or even atmosphere from the NWA
6704 parent body!

NWA 6704 has a Total Known Weight of 8387 grams in a single, naturally
fractured stone that was discovered in Northwest Africa in 2010. In their
eagerness to see what was ?inside? the stone, the Algerian finders
unfortunately broke the largest pieces, as can be seen in the image of the
reassembled stone below. Also visible are the natural breaks along extended
segment boundaries which have been sandblasted over time in the Sahara,
smoothing the edges on the largest pieces and a more ?rounding? of the
smaller fragments. Oddly, NWA 6704 is almost entirely devoid of visible
fusion crust; only a single 1.5cm x 2cm patch exists, raising questions as
to how this can be. Through a determined effort over a four month period,
the distributed parts were purchased by Greg Hup? and reassembled into a
single stone resembling a ?puzzle?. It is remarkable that the finders were
able to collect even the smallest of fragments!

[TKW corrected here]
Northwest Africa 6704 (NWA 6704)
Purchased: 2011 Feb-May
Classification: Ungrouped achondrite

History: A single, dense, yellowish-green stone was found in pieces in
Algeria, and was purchased in February 2011 at the Tucson Gem and Mineral
Show and over subsequent weeks from Moroccan dealers by Greg Hup?.
Physical characteristics: Forty two pieces fit together as a single ovoid
mass (8387 g) with rounded, shiny exterior and small patches of remnant
black fusion crust. The interior is mostly pale yellowish green with rare
darker brownish grains and sparsely distributed small grains of opaque oxide
and metal.
Petrography: (A. Irving and S. Kuehner, UWS): Overall medium grained with an
igneous cumulate texture. Small grains of olivine (0.5-0.8 mm) and chromite
(0.1-0.6 mm) enclosed within large (to 4 mm) orthopyroxene oikocrysts, which
are in turn surrounded by large optically continuous, intercumulus grains of
untwinned albite and <0.1 mm awaruite. The silicates contain curvilinear
trains of tiny rounded inclusions (2-20 ?m), which appear on polished
surfaces to be empty bubbles with smooth rounded walls.
Geochemistry: Olivine (Fa51.6-53.2; FeO/MnO=120-140; NiO=0.9-1.0 wt.%),
orthopyroxene (Fs41.6-42.4Wo2.8-3.6, FeO/MnO=81-82; Cr2O3=0.3 wt.%),
plagioclase (Ab92-93An4-3Or4). Oxygen isotopes (R. Tanaka, OkaU): replicate
analyses of acid-washed material by laser fluorination gave: ?17O 1.015,
0.880; ?18O 3.922, 3.613; ?17O -1.048, -1.020 per mil.
Classification: Achondrite (ungrouped). This specimen is unlike other
achondrites in its combined features: relatively ferroan mafic silicate
minerals with elevated FeO/MnO ratios and anomalous Ni contents, extremely
sodic plagioclase, very Ni-rich metal, and oxygen isotopic composition that
plots within the field for acapulcoites-lodranites. Weathering is low and
limited to minor coatings of pale orange desert dust on broken surfaces.
Specimens: A total of 20.5 g of type material and two polished thin sections
are on deposit at UWS. The remaining material is held by GHup?.
