Amazing Stories (Heritage House): Treasure Under the Tundra: Canada's Arctic Diamonds (Paperback)

It is said that the sparkle from Canadian diamonds mimics the awesome and seductive radiance of the northern lights. Yet until 1991, no one thought diamonds could even be found in Canada--no one except geologists Chuck Fipke and Stu Blusson, who uncovered diamond-rich kimberlite in the Barrens at Point Lake in the Northwest Territories. Their spectacular discovery caused great excitement in international diamond circles and sparked the largest claim-staking rush in Canada since the 1896 Klondike gold rush.

The two geologists sank their lives and savings into their belief that they'd find diamonds in the Barrens, and the story of their quest is a dramatic tale of perseverance in the face of immense odds.
