“Conflict diamonds” or “Blood Diamonds” are largely a problem of the past. Since the early 2000s, the industry has set in place strict controls—called the Kimberley Process—to ensure that no diamonds coming from conflict-zones are traded. Currently, the World Diamond Council is focused on strengthening the scope of Kimberley.
As a result, 99.8% of all natural diamonds are certified by the Kimberley Process as conflict-free. The majority of natural diamonds today come from Siberia, Canada, Australia, and Botswana. (Botswana is one of the most peaceful, prosperous, and democratic countries in all of Africa.)
