Flawed, Precious Stones Carry Clues From Deep in the Mantle

Earth’s oxygen-rich atmosphere creates extremely oxidizing conditions at the surface. Anyone who has seen rusty metal has observed oxidation in action: the oxygen steals electrons from the metal, creating crusty, red, iron oxide. Within Earth’s core, however, low levels of oxygen create much more reduced conditions. Intuitively, many researchers have supposed that Earth’s layers become less oxidized with depth, but few samples have emerged from the deep Earth to support or disprove this idea.
