Top 5 Biggest Diamond Mines In the World

Diamond mining is one of the world's most prestigious and profitable industries. For centuries, diamonds have been an essential component of royal crowns. But in addition to jewellery, they are used in business and science. Being the most complex material on Earth, they’re used to cut, drill, or grind other hard materials. 

The diamond industry is a multibillion-dollar market. Diamonds are used to manufacture tools and machinery, such as drills and saws.

If you're interested in learning about the treasure houses of diamonds (a.k.a. diamond mines), you're in the right spot. Several methods are utilized to reach the world's diamond reserves, including open-pit, underground, and alluvial mining (used for riverbeds and beaches).
