Diavik's diamonds are forged by intense heat and pressure deep within the earth of the arctic north.  55 million years ago, volcanic activity injected kimberlite magma towards the surface, bringing with it diamond bearing ore and forming the kimberlite pipes which are today mined for its precious ore.

The Diavik Diamond Mine is located in Precambrian rocks of the Slave Geological Province. This ancient rock was formed about 2.7 to 2.5 billion years ago and is among the world's oldest geological structures. The Slave Geological Province is known to host deposits of gold, copper, zinc and diamonds, and has produced much of the North's mineral wealth.

Kimberlites are the roots of small and ancient volcanoes and are a common means by which diamonds are brought to the surface of the earth. The Diavik Diamond pipes range in surface area from 0.9 to 1.6 hectares and extend well below 400 meters below the surface. As an indication of the rarity of diamond-bearing kimberlite, only 23 of the 5,000 kimberlites found in the world contain enough diamonds to mine.
