I looked through the catalog and was shocked to see unclassified and
unnamed stones being offered up as lunar and Martian meteorites! Wow,
the consignor must have saved a lot by completely bypassing the
classification process. Just throw out a worthless COA instead!
In the case of the La'gad stone, it looks as if somebody may be
confusing the red caliche deposited by Long-term weathering for crust.
Also the window displays saw marks! What ever happened to pride in
workmanship?

La'gad doesn't show up in the Meteoritical Bulletin. What institution or
scientist examined this exact specimen or is it unofficial or self-paired?

I had the honor and the pleasure (while they were temporarily in my possession)
of personally examining up-close some of the meteorites in this auction that
are from Western Sahara. I am no longer in possession of any of the meteorites
in this auction. All of these specimens from Western Sahara appear in the
Meteoritical Bulletin where all of the coordinates, masses (and the number of
pieces) and the owners are listed. All of the specimens from Western Sahara in
this auction can be considered the official main masses.
For clarity, where I may have relevant experience or have information that is
additional to what appears in the MBD or the auction description, I may feel
compelled to share those facts (some of you may remember, this List was
originally an educational, information-sharing forum). For instance:
I feel compelled to clarify the description for the La'gad specimen in this
auction:
https://preview.tinyurl.com/La-gad
Where the description states, "this specimen exhibits an irregular exterior with no
fusion crust", I would disagree and instead add that the images depict a
relict-fusion-crust where the surface is smoothly curving, it represents the original
ablated exterior of the La'gad meteorite. The only evidence remaining that this surface
was once covered in glassy fusion-crust is the iron-stained palagonite clay, the
end-product of devitrified glass. This is not a carbonate, and it is distinct from the
iron-stained caliche that is typically found in the crevices of most of the Lunar
specimens from this locality.
The surface that was fusion-crusted may be more apparent in this Randy Korotev

So, to all of you who have expressed an interest in Western Sahara meteorites,
thank you for giving me an opportunity to write on this subject.
And, at the risk of sounding like "David S. Pumpkins"...., "Any questions?"

There is a Eucrite in this auction that may look familiar, and I don't mean
because it looks like Bierschinken. It is NWA 7496 --
and here is where you have seen it before:
http://meteorites.wustl.edu/mugshots/nwa_7496_polymict_eucrite.htm
All photos by Randy L. Korotev
And it made an appearance in the textbook titled, "Asteroids":
http://bit.ly/2hvLJuD -- as well as, here: http://bit.ly/2ioeRn5
And here, as well: http://meteorites.superforum.fr/t6532p25-bonjour-a-tous
Although this "pin-up girl" of a Eucrite is a numbered NWA, it has published
GPS coordinates that show it was found in the country of Western Sahara.
Enjoy,

I just received my copies of the Heritage Nature & Science Auction
catalog. The photography is stunning. There are so many items and the
images are so large, they had to make two separate catalogs: one catalog
for all of the gold nuggets, gemstones, and fine minerals -- and in the
other, are the many meteorites.
Unlike most of the more recent auctions in which the Lunar and Martian
specimens are slices, there are some sizeable whole stones of planetary
material here.
You may want to add this to your calendar:
2017 November 4 Nature & Science Signature Auction - Dallas #5324
https://fineart.ha.com/c/auction-home.zx?saleNo=5324
Although it pales in comparison to the hardcopy catalogue, there is an
online-version for your convenience at this link:
https://fineart.ha.com/c/ecatalog.zx?saleNo=5324&ic5=CatalogHome-AucType-PrintedCatalogViewer-071515
I found it to be an educational read. I hope you find it to be enjoyable.
