A friend of mine brought me some strange chunks, thinking they might be little meteorites. He said that whatever they are I can have them. LOL Here are some bad pics ... the first 2 are dry, the last 2 are wet ... First, I'm just about positive that they're not meteorites. They're VERY heavy for their size, they do attract a magnet, and they do look a bit like some meteorites I found on the web, but I think they're probably Magnetite with Pyrite (yeah, I know, the pics don't show the gold flecks). One piece, not included in these pics because it's already on my display table, has small, very glittery black crystals on it! I'm sorta wondering if these chunks could be sliced and cabbed. They'd be shiny black with gold Pyrite specks, without a doubt very beautiful. I'm just wondering if this stuff would be likely to ruin a saw blade and/or be very hard to grind down and polish. Anyone have experience with something like this?

Do a streak test on them. If you have anywhere from a reddish brown to a black streak- they are most likely iron minerals. If you don't have a streak- they COULD be meteorites. Further testing would be necessary. To be honest- they don't even look like meteorites.

They don't show any exposure to high heat, melting, fusing together, etc., like they would have received by passing through the atmosphere at high speed. Not likely to be meteorites. Bob

Hmmm, I dunno. These all have Pyrite flakes and/or flecks in them. I sent a piece to Phil (steelandstone) as a freebie in a box of rough I sent him, and I'm hoping that he can give an in-hand expert ID or opinion.
