Dear Collectors,
Here is my first "summer bargains" list. I am sorry it is going out at such a weird time, this was the soonest I could pull something together. I do realize that, in general, these are larger/ more expensive pieces than a usual list. But then the point of this sale is to raise at least a reasonable sum to pay bills and a lawyer or two.

BEDIASITE: Texas tektite.
This is a large specimen, unfortunately, has a large chip (about 25mm x 25mm) on the bottom. But then, with it sitting on a shelf (wood not glass anyway) or a table, you cannot see it. The remainder of this is fairly plain with very shallow etching that still seems to show a good amount of flow/ stretching lines. I think that this is my only Bediasite specimen remaining.
32.9 gram chipped individual – 37mm x 31mm x 18mm - $175

CASILDA, Argentina: (H5). Found 1937. Tkw = 18.35 kilograms.
Here is a beautiful complete slice from the 13 kilogram piece I bought a few years ago (that had been sitting in a Denver basement for 10 years before I bought it). This is dark but quite fresh showing lots of metal in a mottled dark greenish gray/ almost bluish gray matrix. I think this is the only complete slice I have of this and certainly the only piece I'll sell at this price (this usually brings around $4/g).
452.9 gram complete slice – 165mm x 40mm x 6mm - $900

DHOFAR (026), Oman: Lunar anorthositic melt breccia. Found 2000. Tkw = 148 grams.
This is one moon rock that, frankly does not look like one. This has just the occasional small (really small) bright white fragment in a brown matrix. Not exiting but not real common either.
.39 gram part slice – 15mm x 9mm x under 1mm - $400

NWA (2824): diogenite, anomalous. Found 2005. Tkw = 485 grams.
Here was a really weird rock that really did not look like a meteorite when I got it. Luckily, it was and a rare one no less. It, mineralogicaly is a diogenite but its oxygen isotopes show that it is not from Vesta. It seems to be from the same parent body as the famous Ibitera eucrite. Like Ibitira, this meteorite also contianed vesicles. However, unlike Ibitira, these are very small and few and far between.
a) .9 grams – 15mm x 11mm x 2mm - $90
b) 5.8 gram slice – 45mm x 28mm x 2mm - $500

NWA (2871): (Lodranite). Found 2005. Tkw = 2467 grams.
Here is a nice solid natural fragment that could easily be cut into slices (I thought about cutting into a couple nice end pieces and may yet do that). This was originally classified as an acapulcoite but later work showed that its fairly large crystal size showed it was really a lodranite.
50.3 gram natural fragment – 40mm x 35mm x 20mm - $1000

NWA (2968): achondrite ungrouped (Dunite). Found 2004. Tkw = 268 grams.
This was among the largest of the blocky fragments that made up this weird meteorite. I made the mistake of trying to cut a few pieces of this but it simply crumbled into little cubic and rectangular pieces. It later turned out that this meteorite was pretty much nothing but shocked olivine. As such, I think it was the first or second dunite known (a dunite is a "rock" that is pretty much all olivine). This is my only piece and the others sold out (quite rapidly) at around $200/g.
9.65 gram fragment – 18mm x 17mm x 14mm - $800

NWA (4857): Martian (Shergottite). Found 2007. Tkw = about 1 kilogram.
This is a really nice piece of the "new" Mars rock that was available 5 years ago. This was the first time that collectors could get a nice basically complete Mars rock individual. This is a particularly nice complete piece for this material. It has a nice rounded (oriented maybe) shape and wind polished fusion crust covering probably 85 to 90% of its surface.
1.72 gram complete individual – 11mm x 10mm x 8mm - $650

NWA (5745): (Ureilite). Found 2006. Tkw = 9kilograms.
For some reason this is listed as "provisional". Tony Irving did the work on this and confirmed that it was indeed a) a ureilite and b) the same as NWA (2218). None of this was a surprise as the Moroccan that had the original 9kg piece broke it apart at the Tucson show. David Gregory got the bulk of it – about 6kg
(NWA (2218)) Mike Martinez and I got about 1.5kg (NWA (5745). Anyway, this nice end piece seems to be my last specimen of this stuff. This was really hard to cut (thankfully that was Mike's problem). The research showed that this was a bit unusual in that was very low in pyroxene and is composed mostly of olivine with graphite and micro-diamonds (hence the hard cutting). This piece sits nice to display naturally. 
71.3 gram end piece/ cut fragment – 55mm x 40mm x 22mm - $1000

ODESSA, Texas: Coarse octahedrite (IAB). Found 1922.
Here is a not so beautiful but interesting piece of this hard to come by now meteorite. It is a fairly plain flat specimen that that has only minor thumb-printing on one side. It has a rather large split in it that nearly breaks the thing in two. Thinking this was simply a weathering crack (even though the rest of the specimen is nice and solid) I had thought of possibly finishing the job and making two end pieces out of this. I began "work" on this thing by wire brushing it a bit (only moderately, I left the pockets natural). Some quasi-shiny chinks of material fell out of the "weathering crack". It turns out that this is NOT really just a weathering crack (where the meteorite splits apart along the Widmanstatten structure) but a cohenite inclusion! I figured this out by running the XRF on a chunk of the material that fell out – high Fe, a bit of Ni and only a little bit of S or P (ruling out troilite and schreibersite). So, I decided to leave the thing as it is (some cohenite is still indeed visible in the narrow end of the crack). This specimen will come with the 6.3 grams of cohenite I recovered while brushing this iron.
1270 gram individual – 125mm x 70mm x 35mm - $700

SEYMCHAN, Russia: (Pallasite). Found 1967.
Here is a super thin etched complete slice that is roughly 40% pallasite so it shows nice etch structure in the metal zone but still has nice pallasitc zones. This was cut using a wire saw (an expensive endeavor as this meteorite is generally hard to cut) and is polished on one side (the "back" still shows some wire saw marks) but etched on both sides. There is some minor rust spotting on the back unpolished side (this spent some time in humid climate while uncoated0 but this is minor and has not spread what so ever in the years I have had this set aside (4 or 5 maybe).
74.5 gram super thin complete slice (40% pallasitic) – 155mm x 80mm x under 1mm - $375

SEYMCHAN, Russia: (Pallasite). Found 1967.
Here is my personal collection biggest and best slice that was cut from a 5kg or so block I got years ago. The crystals in this are really gemmy and this is nearly as pretty as Esquel or Imilac. I thought I had this sold (for higher than the price here) so I was not worried about the $ and lawyers issue. However, the buyer changed their mind and decided that they could, after all, live without the piece (in all fairness, they already have several pieces that are as nice as this, just not quite as large. I know – they got those from me and they were cut from this same block). I could have sold this in Tucson for over $10k (to someone that had seen it the previous year) but I did not bring it as I was told there would be a bunch of really nice large slices for really cheap at the show. It turned out that these slices were nice but really large (2kg or so I think), had a lot more metal in them and were priced at $10/g anyway! (and supposedly sold out no less). Oops!
990 gram gemmy complete slice – 270mm x 200mm x 3mm - $7500
