Thanks @doubleunary.  Note that this person has been walked through this checklist and has gone as far as getting his rock identified as "rock from hydrothermal vent". He posts about once a year to ask the same question.

Perhaps someone can clarify: I'd had the impression that some of the earliest "magnetic stones" found 2,000 years ago were of meteoritic origin... So I'm confused in the self-test checklist that "attracts magnets" is immediately disqualifying.

@paulgarrett I don't see how "attracts magnets" is disqualifying, the paths 1-2-4-5-7 or 1-2-3-8-7 both lead to "Send me some photos".

<p>I witnessed a meteorite fall. I have had some test done. I believe it is a Martian meteorite. It seems very hard to get any help and was looking for a company who authenticates Martian meteorites for a fee.</p>

Also https://astronomy.stackexchange.com/questions/33770/oxygen-isotope-analysis?noredirect=1&lq=1 You do not have a Meteorite.  You may have a piece of basalt from a hydrothermal vent.

I witnessed a meteorite fall. I have had some test done. I believe it is a Martian meteorite. It seems very hard to get any help and was looking for a company who authenticates Martian meteorites for a fee.

An easy way to determine whether a rock is a possible meteorite and worth a look by a scientist is to walk through the [Self-test checklist](https://sites.wustl.edu/meteoritesite/items/self-test-check-list/):

![flowchart](https://sites.wustl.edu/meteoritesite/files/2024/04/Self-Test-1c68230331dd6b2c.jpg)

Debora Rios and colleagues at the Nacional/UFRJ in Brazil, adapted by Randy L. Korotev, [WashU](https://sites.wustl.edu/meteoritesite/items/self-test-check-list/)

Also take a look at [Meteorwrongs](https://sites.wustl.edu/meteoritesite/items/meteorwrongs/).

If the rock passes the self-test, and you remain convinced that the rock is a meteorite, you will find pointers to institutions that study such rocks at one of the pages linked at the above site.
