Summary:
People have been finding loose diamonds across the United States and Canada since the early 1800s, but for the most part, no one knows where they came from. It was not until the 1990s that geologists tracked down the first commercial deposits, on the remote tundra of Canada's Northwest Territories. Yaakov Weiss, a geochemist at Columbia University's Lamont-Doherty Earth Observatory, is investigating the origins of these rich diamond mines.Content analysis:
