No one congratulate me, I haven’t gotten engaged or anything.
But, if that should ever happen, I’d want be able to give something more special than gold or diamonds. And what could be better than making a ring out of metal that fell to Earth, flaming, from the heavens? 
My question is; how hard would it be to get enough meteoric iron to make a ring out of? How much might the metal cost, and how hard would it be to have it made into a ring?
You mean like this?
You rock. 
That is too cool! I think I might get one for the little woman. 
Yeah, but wouldn´t it be a real bummer on the weding day, if you find out that your fiance is a lizard-woman? 
That ring is nice. I do have to wonder if these guys are really using meteoric iron [as they seem to be pulling some purported “facts” about the meteoric material they are using right out of their ass](Here is a simple, primitive design carved from Gibeon meteorite metal. It is a nice, chunky pendant that can be worn on a silk or leather cord, as well as a silver chain. We acid etched this piece to bring out the Widmanstatten pattern, a crystal structure that occurs only in iron of meteoric origin. It is interesting to note that small amounts of the elements Enstatite and Tridymite can be found in the Gibeon meteorites. These elements occur only as a result of nuclear fusion. It’s fun to wear a piece of a star! Pendants start at $75.00, the pendant shown is about 15 millimeters in diameter. ).
You realize that every atom more complex than hydrogen and helium in you, your fiance, and in any ring you could possibly obtain was forged in a star by nuclear processes? The iron in your blood and the calcium in your bones was once part of a star. That’s pretty cool too.
Not the ‘elements’ Enstatite and Tridymite.
We are all star-stuff.
That’s what I was talking about. Apparently they have a new and improved periodic table that I don’t.
They are correct about the Widmanstätten pattern. If it does show that, then you can be sure it’s from a meteorite.
I’ll also note that one of our friends from graduate school (in planetary science) got a ring with an impact diamond when her now-husband (also in planetary science) proposed.
Just in case you want to go that extra mile.
Those are iron minerals, not elements.
Ooops, enstatite doesn´t have any iron on it… my bad, carry on.
Yeah, but if the meteorite were melted down and cast into a ring those markings would not reappear, would they?
Now, say I buy a ring. How can I be sure it’s authentic? I mean, I can buy “Moon Rocks” in a plastic baggie at the toy store.
Short of pulverizing it and doing extensive chemical tests, how can anyone buying from this site know they’re not being ripped off and getting recycled car parts?
Also, wouldn’t it rust, being made of iron and all?
When I got engaged, I had this exact same thought. In fact, more than a thought, I bought some meteorites and pursued it. There are glass-like meteorites as well, and I was thinking about making stones from it.
There are a couple problems:
First, I was thinking that since meteorites are rare, that they would be valuable. Wrong! I bought a handful (enough for 10 rings) for $20. Many people say money has nothing to do with love, but if my wife-to-be found out I’d spent only a bit more than I could’ve paid for one from a Cracker Jack box, well, I’m not sure she would’ve been impressed.
Second, meteorites are primarily iron. Which means that it’s an ugly metal and will easily rust.
Third, iron is difficult to make jewelry with because it’s so hard and has such a high melting temperature. As a teenager, I worked in a dental lab, and have some experience making crowns, and had made jewelry at that time using those techniques (casting of copper, silver or gold). And I couldn’t do that with iron. I thought about other techniques, such as grinding it down, but meteorites aren’t solid; they’re filled with small bubbles. So to make the ring nice, melting the metal is important.
For an unusual ring, how about Tungsten: denser than gold, very hard and certainly not cheap.
Adamantium!
