Cut in half, Any thoughts?

[jungliston1]

Hello all, had this cut by a rock and gem store. Store owner, when he finished cutting it said, he had never seem a terrestrial rock like this. Any thoughts as to what kind of rock?
Thank you for the help,

Can we have more context as to where it was found? You don't have to say exactly where.........Do you have other pictures showing the outside features of the rock?

Thanks

Rick

There are a variety of ores that when cut show the patterning you have there, and meteorites as well though I rule that out for your specimen. One can see a large number of crystal boundaries and by the distortion your stone has been altered by high pressure much like metamorphic rock. As to its composition check for magnetism, try a streak test, hardness test, specific gravity test and if you can find someone with an XRF reader it would help. Off the cuff I'd guess its a mixture of iron sulfides much like pyrite.

Possible rocky meteorite, looks like the
Chelyabinsk meteorite sample.

The Chelyabinsk meteor was the size of a small apartment building, not the bus size as reported in the news.

Can see where DDancer is coming from.....A meteorite iron pattern is generally like this:




There are few others with meteorites. If Edward adds more parts of the puzzle together here, it would be resolved I would imagine?

LL Chondrite

Not all meteorites are full of metal

Chondrite- They are the most common type of meteorite that falls to Earth .

Take it to a University and have it X-rayed .

Widmanstätten patterns, also called Thomson structure ~ the lines you see in Sierra's photo~ are a result of etching a meteorite and are not apparent otherwise as a result of just cutting a stone. At least not to my knowledge. You could slab another bit and give it a shot though. I'm not convinced that it is a meteorite due to the apparent pores in the material and its low luster for metals endemic of metallic or mixed stony metallic meteorites I have seen over the years.
Just my opinion however. Could you post a picture under natural light and a view or two of the other sides of the specimen?

Was using that as a comparison.........

Didn't want to say which meteorite has a smooth finished polish surface like that until jung posted more pictures.......

Some kinda iron-oxide; hematite or magnetite? Streak test it!

Hello all, had some XRF Scans done on some of the rocks I had to see the elemental compositions of them. Any help to point me in the right direction would be great. The 'UNKNOWN', is for both Specific Alloy and the Geo Standard of known compositions. Thank you for the help,
