A piece of meteorite from the Campo del Chielo fall in Chaco, Argentina. The iron crystals formed at the same time as the formation of the planets of this solar system, some 4.55 billion years ago. The fall was about 4,000 years ago. A simple loop has been attached to make this into the oldest pendant you can find.
