Naomi Campbell appeared in a Netherlands courtroom to testify in the case of Charles Taylor, a ex-Liberian ruler who is charged with eleven counts of war crimes ... including giving a gift of blood diamonds to the supermodel.

The alleged gift was given at a September 1997 dinner that was hosted by South Africa's former leader, Nelson Mandela. Campbell says she recalls being given a pouch with "dirty-looking stones."

Prosecutors claim that this is proof that Taylor had been illegally selling diamonds to pay for a civil war in nearby Sierra Leone from 1992 to 2002. In addition to Campbell being a guest, Mia Farrow and Quincy Jones were also at this 1997 dinner party.

As to why Campbell was given these stones in the first place is still being investigated. Charles Taylor is also accused of sexual enslavement, murder, rape and recruiting child soldiers.
