Is it meteorite? 5kg, 17×13×10cm

I would say Iron ore. Meteorites arrive under very high heat . They are usually pock marked and appear glazed. The red you see is rust most likely.

 

Ditto.

 

Lodestone

 

Isn't lodestone magnetised, like a magnet?
This stone has a magnet on it, so presumably ferrous, but Adam didn't say the stone attracted iron or steel items like a magnet does.

 

Magnet attracted to the stone.
The stone is not metal. I tested it with metaldetector

 

Iron ore is a stone from which iron is extracted. Hematite, for instance, is such a stone. Hematite is also used in jewellery.

 

Probably a lump of magnetite that has been knocking around for some time, hence the rounded edges and the colour. Though it is full of iron ore, typically 45-55%, though it will attract a magnet, it isn't in itself magnetic, unlike lodestone. The highest quality can up to nearly 80% iron.
Hematite, isn't magnetic at all, and doesn't rust either.

 

Stone is not attracted to iron thing. That black ring in the picture is magnet. I want to show that magnet attracted to stone

 

That is what we meant too.

 

So the real question is whether you can stick the rock on your refrigerator.

 

Yes, you're right. This is the kind of rock you can put in a machine and make it magnetic! I think it has to have a certain high percentage of iron ore but I'm not sure what the rest of the stone is made up of. We have the machine at work that magnetizes them.

 

This is what is inside many iron bearing meteorites ....
