This is a piece of the Fukang meteorite, a 1,003 kilogram meteorite discovered near the Chinese city of Fukang.
It is a pallasite, a type of stony–iron meteorite, with olivine crystals throughout. Only about 1% of all meteorites are pallasites, and this one is believed to originate from deep inside intact meteors created during the formation of the solar system about 4.5 billion years ago
