I suppose it would be possible to artificially blue an iron meteorite. Being
a gun collector, I do know a bit about it. This Sikhote is definitely not
artificially blued. The black oxide that blues metal is only ~2.5
micrometres thick. This crust is MUCH thicker and only resides in the
regmaglypts where less wear would naturally occur. I believe an artificial
blue would be easy to recognize for some people, but you never know! As
people say, buy from reputable dealers!

Now I'm curious what an artificially blued Sikhote looks like. It is a
wonderful preservation technique for gun barrels, but if misrepresented on a
meteorite, could be a bad deal! Anyone have an artificially blued meteorite
to post?

Cheers,
Mike

Hi Mike,

Interesting you should say that. I remember a discussion on the list a few
years ago as to whether or not some Sikhote-Alins had been blued to improve
their appearance.

Crust on irons...most definitely! This Sikhote has THICK crust in some of
the regmaglypts. Thick enough that you can chip it off. It's like Blued Gun
Metal.
