Heating iron meteorites is not a good idea. High heat alters their crystal structure. Even when cutting or grinding iron meteorites you need to prevent them from getting excessively hot. Come on James, just a little 300-400F on the surface. I had no idea they are that sensitive. Super hot may not be a good description. But a good firm buffing does have effects on slowing rust. Certainly there is a higher temp buffing compound of the wax or urethane family that would leave a rust proof coating. What do you think ? Heated powder coating does wonders. Research it if you disagree. I have been in to meteorites for quite a few years and have done a lot of research. The meteorite sites state not to get the iron meteorites hot, even from cutting. If you don't agree then don't challenge me challenge the meteorite experts who said this first.

1dave, what kind of meteorite is the ring made of? Did your son-in-law's finger turn red when he wears the ring? I wondered if he may be having an allergic reaction to nickle? I read an article that mentioned the Muonionalusta meteorites are sometimes sold as Gibeon. How do you discern the difference between the two? Hi Jan, if it's the same article I read you check to see if it came from a Chinese jewelry supplier and set your stop-watch to see how fast it starts to rust LOL! Here's some info on stopping rust. Vegas James may have better/more specific info but check this out: www.meteorites.com.au/odds&ends/ironrust.htmlIt is really sad to spend a lot of money on a beautiful piece of iron meteorite just to have it rust away in a short time. That is why I avoid collecting certain iron meteorites such as Nantan, because they are notorious rusters. Personally I think the best bet is to remove the meteorite clean it up and re-etch it, then zinc plate it. This should stop the rusting as the zinc would act as a sacrificial metal while still allowing you to see the etch pattern.

I have seen zinc jewelry from Turkey. Why not do the zinc ? I assume by electro-plate ? Would it not cover up the patterns of the meteorite ?

Sorry, but they live near Seattle in Washington, I'm down in Cedar City Utah. I gave them this web location. Perhaps they will chime in ?
