Fuelling wars

Rough diamond caches have often been used by rebel forces to finance arms purchases and other illegal activities. Neighbouring and other countries can be used as trading and transit grounds for illicit diamonds. Once diamonds are brought to market, their origin is difficult to trace and once polished, they can no longer be identified.

Did Someone Die for That Diamond?

Some diamonds have helped fund devastating civil wars in Africa, destroying the lives of millions. Conflict diamonds are those sold in order to fund armed conflict and civil war. Profits from the trade in conflict diamonds, worth billions of dollars, were used by warlords and rebels to buy arms during the devastating wars in Angola, the Democratic Republic of Congo (DRC) and Sierra Leone. Wars that have cost an estimated 3.7 million lives.
