Northern Canada is an oasis of pristine wilderness where, for millions of years, a major repository of spectacular diamonds lay dormant. Canada’s magnificent gems were once buried under fields of ice 3,000 meters thick. As the glaciers melted, the indicator minerals that traditionally lead to the source were spread out over thousands of kilo meters across the barren tundra, making it a challenge to pinpoint the rich veins of diamonds. Eventually, success! In recent years, Canada has become the third largest supplier of gem quality diamonds to the world.
