The stone meteorites.
|The nickel iron compound is in the most stone meteorites that is why the space stones are heavier than the terrestrial ones. But their main minerals are silicates (olivine and pirogues).

They consist of the same material as the meteorite, but look like separate grains on its out. Their origin is not clear yet.|
