A Canadian mine says it has broken its own record for the largest diamond ever found in North America.
Dominion Diamond Mines has announced the "unexpected" discovery of a 552-carat yellow gemstone.
It was found in October at the Diavik Diamond Mine in the Northwest Territories, which is 135 miles (215km) south of the Arctic Circle.
========================================================
Canada has become a major source of diamonds since the discovery of so-called 'kimberlite pipes,' which are the geologic formations left after the death of ancient volcanoes.
