CHONDRULES
Chondrules were the first masses to form out of the dust and gas of the cloud that later became our Solar Sytem. Bound together by weak gravitational forces, becoming larger, stronger, crashing together, forging planets, collasping into asteroids. They were the first. Each one with the potential to become a planet with fate left to decide. They contain the stone and nickle-iron alloys like meteorites do, like planets do. They just never quite made it. These were carefully extracted from a friable meteorite, you can do it yourself with enough time.
