Robert Haag, dealer in meteorites, holding the world's most expensive stone fragment. It is a piece of a meteorite that originated on Mars, and is worth about $1.3 million. It is possible that this fragment was thrown up from the surface of Mars following a giant impact, some of the ejecta being sent out of Mars' atmosphere and into interplanetary space. Such fragments could then drift for millions of years before colliding with another body such as the Earth.
