BRENHAM, Kansas: Stony-iron (Pallasite). Found October 30, 2005.
I must have sold a lot of pieces like this one years ago. It seems that every time I sell one that has come back to me, another appears. Like the others, this was cut from a 69 kilogram all iron specimen that Steve Arnold found on the date listed above. This has one natural edge that is about 50mm long with the remaining edges being saw cut. This is etched on both sides and shows a nice but not super vibrant etch pattern. There are a couple tiny thin brown oxidation lines along a fine crack near the edge (even Gibeon gets those) but they are so fine that I’d risk doing more damage to the piece by trying to mess with them. A good piece that is obviously quite stable, given the environment it was previously stored in.
74.0 gram etched part slice – 50mm x 50mm x 3mm - $120

CAMPO DEL CIELO, Argentina: Coarse octahedrite (IAB). Found 1576.
Here is actually a really nice etched (on both sides) “complete slice”. This does not show a speck of oxidation anywhere! Looking at the edge, I personally think that this was cut from a really large “nugget” – one of those pieces that results from a larger meteorite being broken up after being frozen in liquid nitrogen (gads, I wish I had patented THAT idea when I came up with it to help out a guy that rapidly needed 5000 plus small iron meteorites for a project he contracted for without first checking to see if 5000 of ANY small irons existed at the time – which they didn’t). I have never had a problem with any of those things rusting for some reason, and that seems to be the case with this specimen as well. The etch on this is about as good as these things get – not real clear thanks to the scale of the etch structure but still enough to give the proper idea. This is a perfect piece for a hand or display specimen for someone that needs a truly coarse etch coarse octahedrite.
141.0 gram complete etched slice – 70mm x 50mm x 5mm - $70

ESTHERVILLE, Iowa: Stony-iron (Mesosiderite). Fell May 10, 1879. Tkw = 317 kilograms.
This is actually a “trade in”. I had a 15g piece that I picked up in Tucson but a customer just happened to call shortly after I got home asking if I had a piece of this meteorite. He asked if I would accept a trade in and I said “sure”. This is pretty much a square cut piece that has no natural edges. One edge has a shallow semi-circle indent that is actually from where a core sample for research was removed from the original large specimen. Regardless, this is an aesthetic piece. It has a nice mix of metal and silicates (close to 50/50). This is a thin cut piece that has a good surface area and even passes light (dark emerald green) through several of the silicate crystals.
5.6 gram part slice – 30mm x 26mm x 1mm - $115

NWA (6619): Carbonaceous chondrite (CV3). Found January 2011. Tkw = 3367 grams.
This is an almost complete slice. It has a natural edge around the entire edge except a 50mm straight cut along the bottom. This specimen shows a half dozen or so fairly large chondrules (3mm to 5mm size) and a lot of small chondrules and CAIs in a fairly dark matrix. The official Meteoritical Bulletin description says this has a light gray matrix. I think the issue here is that this particular piece has been quite highly polished (and, as I mentioned on an item on one of the recent lists, this usually darkens a meteorite’s tone substantially). I know that this is “the right stuff” as it does match online pictures of other pieces and comes in a sealed (well, taped shut anyway) display box with the Certificate of Authenticity from Mirko Graul, the person that brought this stone to research. As this is taped, my thickness measurement below is only a good guess.
33.2 gram almost complete slice – 60mm x 47mm x 3mm - $230

NWA (8563) (?): HED achondrite (Eucrite, monomict). Found August 2014. Tkw = 9125 grams.
I put a (?) on the “name” of this one as some quick research indicates that this particular piece is likely NOT from the mass that Mike Farmer bought and had researched under this number. The hand written note that came with this specimen may indicate that it came from the guy he may have gotten his piece from. Even if this is the case, this should have been sold to my friend as “may be paired with” NWA (8563). Regardless, this piece certainly looks like it could be paired based on the description in the Meteoritical Bulletin. This is a complete stone (well, more likely a natural weathered / wind-polished fragment anyway) but it clearly shows that its internal structure is composed of fairly large (cm or two sized) fine-grained eucrite areas separated by black shock veins. Frankly, if this piece were mine (it is a consigned specimen) I’d cut it up as I think this thing would look (and likely sell) great in slices.
367.6 gram natural fragment/ individual – 80mm x 70mm x 40mm - $2000

SAINT SEVERIN, France: Ordinary chondrite (LL6). Fell June 27, 1966. Tkw = 271 kilograms.
I got these two pieces as extras along with a larger specimen that I needed for a lab that wants to do some research on this meteorite. Its been quite a few years since I have had a piece of this material and saw what looked to be some pretty silly high prices when I went about looking for the needed research piece. I managed to find someone that was willing to be reasonable so I got some extras for myself. These are two thin part slices that each has a natural edge (one of the shorter sides on the smaller piece and about 50% of the larger piece) but I wouldn’t call it “crust” (though some super fine secondary crust might be present). Neither of these is much to look at honestly. They have a fairly uniform medium gray color and only some hints of breccia texture (though the smaller piece does have a nice obvious lighter 7mm x 5mm clast in its center). Not beautiful, but rare stuff to come by these days (and these are from an ex Robert Haag specimen so I know they are real)..
a) 4.12 gram part slice – 37mm x 18mm x 2mm - $165
b) 5.23 gram part slice – 40mm x 20mm x 2mm - $210

TAMDAKHT, Morocco: Ordinary chondrite (H5). Fell December 20, 2008. Tkw = about 100 kilograms.
This is the witnessed fall where most of the pieces got broken up hitting rocks high in the Atlas Mountains. This 1/2 end piece (book-end cut) is no exception. Though this has fusion crust covering most of the back -side, most of the edges show fresh breaks. This has a few tiny hints of adhering dirt but no rust so this was an early recovered piece. The large cut face is very light gray (with a 14mm x 8mm lighter yet clast in the center) and shows lots of bright fresh metal. This specimen is in a neat plastic and glass display box that has a built in prop for sitting at an easy viewing angle.
12.8 gram ½ end piece – 36mm x 20mm x 9mm - $50
