Scientists proudly display oldest crystal on Earth

April 10, 2005

A tiny piece of rock 4.4 billion years old went on display in, Sunday for one day only. A jazz band played music, with rocks for percussion, which they said might be appropriate for displaying the bit of crystal, barely two human hairs wide.

The tiny gem was found in in 1984, and analyzed in 2001 by experts, and has led to the reappraisal of early.

geophysicist Professor John Valley said his work proved the crystal could only have formed in a low-temperature environment.

"The whole thing is something that captures your imagination," he told reporters. "This is our first glimpse into the earliest history of the Earth. The miraculous thing about the crystal is that we've been able to make such wide-ranging inferences about the early Earth."

The exhibit was under police guard. The tiny sliver will return to Australia with a professor from in, who discovered it in 1984. It will go to a museum.
