| I recently ordered two new meteorites, which just arrived in the mail today:
First is a cut of Allende, a witnessed fall and an extremely well-studied meteorite. A primitive carbonaceous chondrite, it is made of materials accreted directly out of the solar nebula, and reveals details of the formation of the solar system. It is older than anything of this world, and even the world itself.
The second is a pallasite. I've been wishing for one of these for a long time.  These come from the boundary region between the core and mantle of differentiated asteroids. The core is made up of the dense metals, while within the mantle grow large single crystals of olivine. Mixed together at the boundary, and then shattered free in a large collision, and eventually improbably crashing on Earth... when recovered and thinly sliced, there is revealed a rare beauty. There is a total of about 10 tons of known pallasite, which is only about 3.5% of the mass of all recovered meteorites, and a fraction of the total mass of diamond mined each year.

| Very cool slices, but those must not have been cheap.

| Yeah, pallasites in particular are not cheap. They're comparable to buying platinum by weight. Other types can actually be reasonably cheap to buy though.

| What would be the best asteroid to live on that doesn't orbit a planet? And isn't round?

| steeljaw354, any asteroid accept for Chariklo. Just build inside the asteroid and you have a natural shield from space debris

| Hornblower, I could imagine 43 eros would make a good asteroid base, hollowing the inside out for space, and mining the inside out.

128 Nemesis. Because who wouldn't want to live on an asteroid named Nemesis?

Oh gosh, there are tons of meteorite traders and sellers out there, and I've bought from several over the years. My most recent came from a dealer in Arizona who both buys from other collectors and travels to strewn fields to find new ones.
Just try looking around online. Be sure to do your homework before you buy, though. Obviously try to make sure the seller is reputable. (You can eBay meteorites, but this can be dubious). You'll want to know what a particular meteorite looks like and how much they tend to sell for by weight, so that you don't get ripped off. You'll also want to know how to care for the meteorite. Meteorites contain elemental iron. Iron rusts. So you'll want to take steps to prevent further corrosion of your meteorite. This is especially true for polished slices of iron meteorites. With complete stones you can be less cautious.
Finally, give thought to what kind of meteorite interests you. Most people think of meteorites as small, pitted lumps of dark metal. These are iron meteorites, which are less common falls, but easier to find. It's possible to get iron meteorite fragments for fairly cheap, and they make great show-pieces. But there are lots of other types of meteorites, too, which can look very different and have interesting things about them.

Awesome! 94 grams is a good-sized piece. That wouldn't be the Zag meteorite by any chance would it? That (and Monohans) are the only known meteorites with salt crystals in them!
