Due to its distinct geologic conditions for their formations, the occurrence of diamonds is confined to around 35 countries in the world. While countries such as Australia, India, or Canada focus more on mining industrial diamonds, African countries such as Botswana and South Africa are better known for their production of gem diamonds. Diamond mining activities in many African countries are often also linked to conflicts and controversial human rights conditions.
According to data collected by the Kimberley Process Certification Scheme (KPCS), which covers an about 99.8 per cent of global diamond production, 134 million carats of diamonds worth US$ 12.4 billion were produced in 2016. This most recent figure is slightly up from the average annual production since the start of the financial crisis in 2008.
