World's Oldest Diamonds Discovered in Australia

World's oldest diamondThe world's oldest known diamonds have been found encased in a crystal in Western Australia, scientists say.

The minuscule gemstones are 4.25 billion years old and could provide a rare glimpse into Earth's distant geologic past.

The discovery suggests that seas of molten lava that covered primordial Earth had cooled down faster than had previously been thought.

The find also suggests that plate tectonics, the process by which large shelves of Earth's crust move to create geologic activity may have already been underway.
