Maybe just one more. Here's my very strange 29.5 gram Jepara pallasite.

That is an awesome Fukang specimen, thank you for sharing!!

I'll take some macro shots of mine soon, it looks like a back lit shot is the standard for pallasites??

I have to admit to a weakness for pallasites although right now I only own 3. Here are my Brahin and my little Esquel. The Brahin is my favorite specimen outside my collection of lunars and martians.

Great photos... shame that some Pallasites are put in acid to get the peridot quality Olivine crystals out of them :doah:

18th century German naturalist Peter Pallas probably turnes around in his grave by the idea ...

In the words of some of my Chicago south-side buddies, "Money make ya funny!". I guess profit, for some, is paramount.

I compare it to the killing of wildlife all over the world,
either for its fur or to have it mounted in an attempt to prove to ones self how brave you want everyone else to think you are.
As in meteorites and wildlife all their natural beauty lost for ever.

That is true. For the record, I condemn that practice. There are plenty of loose meteoritic olivines available, without destroying whole specimens to get them. It's kind of like killing a live seashell when the perfectly-good dead ones are lying all over the beach.

Hi,

I feel the need to play the devil’s advocate here. First a little background, I started buying meteorites 35 years ago. The first ones I purchased were for making jewelry. Since then I have become an avid meteorite collector. I have purchased some samples of Admire. The only stable sample in my collection is a thinsection. Has anyone seen a stable translucent slice of Admire? I know I haven’t. I have paid as high as 25 cents a gram for Admire. If the meteorite was stable it would sell for much more. I have seen multi kilo uncut specimens crumble away. I see no problem with dissolving the iron to free the olivine crystals from this meteorite. In my mind the dealers who do this are preventing customers from having the bad experience of watching their new purchase rust away. I say throw all the Admire into acid and save at least part of the meteorite.

Peter

Admire is very unstable, typically. But I have seen some stable Admire specimens. The stable ones I have seen were treated with the Pat Mulvany process. His process will render even the worst rusters into something stable. Unfortunately, he is on hiatus and is not taking work from the public at this time.

Admire needs active conservation or it will slowly disintegrate as Peter said. But, ruster masses can be saved. However, for some people, it's less expenses and trouble to simply destroy the meteorite in acid to harvest the olivines. With a little more money and time, the entire mass could be saved. That seems to be an increasing trend in this country - cheap and quick, instead of doing something the right way. Fast food meteorites!

Best regards,

MikeG

Hello Tom:

GREAT slice of Thiel Mountains - it is really difficult to get that meteorite!!

It is one of a few Antarctica meteorites that can be legally collected:

By the way I think your label is misspelled it says "Theil" instead of "Thiel".

Thanks for sharing...

Best Regards,

Hi All,
Here's an interesting specimen. It's one of my favorites and sometimes it's hard to find. Can anyone name her? Hint - Notice the angularity of some of the Olivine. Also, it has no He, Ne or Ar in its chemical makeup.


NOTE: MARTIN G.(UK), you can't participate. Sorry. :bawling:
