Meteorites to Avoid
      #6049025 - 08/27/13 02:59 PM Attachment (20 downloads)

Hi All:

This is my first post on the Space Rocks forum.

The other day my daughter was asking if I would ever buy a meteorite. I was looking on Astromart at that moment and one popped up for a very reasonable price so I bought it. This got me really interested in meteorites so I did a little reading and got excited and bought a few more

I didn't really know if I paid too much for them but I did some comparison shopping so I don't think I paid way too much if I did. But I liked the looks of these even though I either knew nothing or very little about the history. I was buying to get started.

Anyway, I did some more reading and found out how you have to take care of the iron ones and that they might rust. OK, I thought, that would be a shame for them to rust so I thought I could take care of them and at least I live in a dry climate.

Then my latest acquisition was a small Admire Pallasite. I thought my daughter will really like this one.

I have since read that some of these are not very stable. I have read different opinions, however. So I am wondering if anyone has more information on these. Are they unstable or does it depend on something. How long might they last?

I have enclosed some pics of ones that I have bought. I bought mainly on aesthetics rather than knowing much about them. But now I want to learn more! Lots of fun but I hope I don't spend too much What do you think of my starter collection? Are there any others to avoid that might be rusters or not stable? Thanks very much, Kent

Here is the first one that got me started.

Looks like you're off to a good start, Kent! Several nice specimens there... some that I recognize. I bought my first meteorites on Astromart, too... in 2005, I think. Prior to that, I had no idea one purchase their own space rock, to have and to hold. So I bought 3, thinking that would be he end of it. Ha! I have hundreds now, and need to scale back quite a bit!
Get a copy of Richard Norton's Rocks from Space to start learning more about them. And have fun! But be aware... they're addicting!

Thanks Linton. And thanks for the book recommendation. I was thinking a book would be a good idea. I can't believe how sudden all of this was though. Just because my daughter was talking about it. I just received the small one #3. I knew it would be small at .5 grams but wow it really is small. I need a magnifying glass to really appreciate it.

Yeah, a magnifying glass is a must, even for larger specimens.
But a stereo-microscope will be on your list before long! <g>

Ah a microscope. That reminds me. I do have a very good one that hasn't been used for years. It belonged to my dad who is now retired. I may have to get it out sometime. Under the light that .5 gram "stone" really has some nice features. It glitters. Thanks.

Hi Kent,

Welcome to Space Rocks. And welcome to a new lifelong obsession. Meteorites are like potato chips..... Just ask my poor wife.

You don't need to "avoid" certain meteorites because of rusting issues - instead, just avoid paying too much for them.

The majority of stability issues (rust, lawrencite, etc) are not caused by some inherent problem with the meteorite itself. Most instability is avoidable and occurs during poor preparation work where corners are cut to save time and money. Properly prepared, there really is no such thing as an "unstable" meteorite.

Nantan, Campo, and Admire are 3 good examples of meteorites with a bum rap as being instable. And yes, there are tons of examples of rusting Nantans on the market that look horrible. But, when properly prepared, it can be just as stable as any other iron meteorite.

Irons are much more problematic than stones and stony-irons tend to be a mixed bag. And oddly, some of the biggest and most well-known dealers on the planet do not properly prepare their specimens. I can't and won't name names here, but don't assume that a specimen you get from any famous dealer is stable - quite the contrary sometimes.

Over time, you'll get a good feel for who the dealers are who do the proper prep work without cutting corners. Word of mouth is a good place to start, as is a search engine.

If you have any questions, feel free to shoot me a private message - I can be much more candid in private, because I am a vendor and can't say certain things in the open forums.

Best regards and clear skies,

MikeG

Thanks Mike. Very informative. I had this picture in my mind of my Admire piece falling apart. I guess that could be quite some time if it ever happens. I hope mine was well-prepared but I may never know unless it starts falling apart.

Thanks again, Kent
