Where are diamonds found?
The geography of where diamonds are found depends largely on the volcanic activity of an area. Naturally occurring diamonds are found within Kimberlite rocks, which are found along the trails of old volcanic pipes. Essentially, the diamonds, which form in the Earth’s mantle are thrown up to the Earth’s surface by volcanic eruptions. Often, diamonds are also found in alluvial deposits, which are the sediment deposits left behind by rivers and streams, as the rocks transported by the movement of the water.
Whilst diamonds are relatively rare gemstones, they can be found in a variety of locations across the globe, thanks to the presence of kimberlite. Diamonds are found in 35 different countries, most notably, South Africa, Russia and Botswana, but also areas around Canada, the US, China and Brazil. Diamonds are most often associated with South Africa, as this is where the 83.5ct Star of Africa, once the world’s largest diamond, was found in 1869, sparking the diamond rush of South Africa. Soon after, the diamond monopoly De Beers was founded in area.
Once mined, diamonds move to various hubs dedicated to such professions as diamond cutting and polishing and diamond grading. Located in the USA, the GIA are the most notable diamond grading lab, whilst cutting and polishing often takes place in India and Belgium.
