Hi Tracy,
Great job. The majority of times I have tried to educate a seller, I
have been told to go jump off a cliff. Some people just don't want to
hear bad news, even if it's factual. So this is definitely a victory,
albeit a drop in the vast internet bucket. Now, if only eBay would
start
Thank you all for your suggestions. I have passed them along to the seller,
along with a few reasons why I think the stones aren't real extraterrestrials,
and he is going to pursue the matter with a gemologist and his supplier. One
case of mistaken ID down, 10 to go []
Best!

Hi John, Peter and list
You could also try a sports trophy shop. They engrave on plaques for
the trophies. Some jewelers also have the machines. This is commonly
done with a diamond tipped scribe in a machine and a set of letters
where the scribe would copy the letters. Now there are laser
Thank you Peter!

Hi John,
Sorry, I misunderstood you. For engraving I would try a local gunsmith. If they
can't do, they will know someone who can. I have seen a lot of old time slices
that have their info etched on them and only a few that have been engraved. I
think either way would be great to and some
Peter, All,
Sorry if I'm not being clear.
Really what my buddy is looking for is someone who can engrave neatly onto an
iron slice. Preferrably with a machine of sorts designed for the purpose of
engraving.
Thanks though for the knowledge.
I appreciate your time responding. :-)

Hi John,
I am sure that anyone who etches irons can do this for you. All you need is
a resist. The simplest would be writing on the iron with a crayon.
Traditionally asphalt was used. If I were to do it I would purchase some
stickers since my hand writing is so bad. I am sure that there are many
Asking on behalf of a friend,
If there is anyone out there who provides a service of etching names onto a
slice of an iron meteorite (as if etching a name/phrase on a wristwatch) please
email me at bigjohns...@mail.com.
Thank you!

Dear meteorite-list members,
I thought I would forward this request, which I read via the Mineralogical
Society of America's listserv, MSA-talk. Giulio Solferino is looking for
photographs of the Seymchan pallasite for digital image analysis. Perhaps some
of you can help him or suggest
Distinguishing between terrestrial olivine and pallasite olivine
probably isn't quick and easy. Electron microprobe would show the
difference in the Fe/Mn which is diagnostic. I've never used one, but
a handheld XRF might be able to do this too. If you don't mind
vaporizing the stone with a laser
Once again, I have found someone on ebay (surprise factor zero, Captain!)
selling what I am convinced are fake pallasite cut gems. Unlike the last fake
seller I confronted, this seller seems willing to entertain the idea he may
have a fake or two, and wants to look into having them tested.
Thank you very much to everyone that was willing to share information. I
submitted pictures to the Meteorite Picture of the Day (MPOD) so everyone can
see this wierd stone.
Thanks, Derek.__
