Oldest diamonds discovered in the world

Geology - In Australia, researchers have found diamonds, which are
more than four billion years old, making it only slightly younger than
the Earth itself as jewelry are not good are the microscopically small
stones. Nevertheless, they are very valuable for the research because
they allow conclusions about the early history of the earth.
Seven million years could be measuring wrong, but something like a
huge uncertainty, disappears in the face of the dimensions at issue
here: 4.252 billion years old are the diamonds, the researchers at the
University of Muenster have been excavated in Australia. "We have
worked with the diamond carbon, the oldest relic in hand," said the
mineralogist Thorsten Geisler. Carbon is a basic building block of
life.
Report their find Geisler and his collaborator Martina Menneken in the
British science journal "Nature" (vol. 448, p. 917). Although diamonds
can not be dated directly, but these pieces of jewelry from the early
history of the earth in the mineral zircon included. And the age of
zircons can be determined absolutely.
