Johannesburg, South Africa (CNN) -- A friend of supermodel Naomi Campbell handed over unpolished diamonds to South African police the day that Campbell testified at a war crimes trial for former Liberian President Charles Taylor, police said Friday. Police spokesman Musa Zondi told CNN that the diamonds are real. Campbell testified Thursday at a United Nations-backed Special Court for Sierra Leone that she had received the diamonds as a gift, then turned them over to her friend Jeremy Ratcliffe to auction for charity. She said on the stand she believed Ratcliffe still had the stones. Zondi said Ratcliffe could face charges of possession of unpolished diamonds.
