Allende is often called the "best studied meteorite in history". It contains microscopic diamonds with unusual isotopic signatures that point to an extrasolar origin. These interstellar grains are older than the Solar System and may have been produced by a nearby supernova. They represent some of the oldest matter known to man and are estimated to be 4.567 billion years old....and amazingly they are 30 million years older than the Earth.
