Diamonds

Throughout history, society has chosen many ways, including diamonds, to display wealth. Diamonds are rare and ancient and gems from the Northwest Territories are up to three billion years old.

The majority of northern diamonds are gem-quality and destined for jewellery.

As the hardest known material, diamonds have been used for centuries as an abrasive in cutting, drilling, grinding and polishing. This is the dominant industrial use for diamonds.

Diamonds also have the highest thermal conductivity of any material at room temperature and are used as a sink to dissipate heat in electronic devices such as computers and diode lamps.
