It might be the ugliest diamond you'll ever see, but within this brown sliver of carbon is a gem of a find for a University of Alberta scientist working to unravel an ocean-sized mystery deep beneath the Earth.

These findings support the theory that much of the Earth's original crust has been recycled by the process of subduction, helping to explain how the Earth has formed and changed over time.
