(CNN) -- Actress Mia Farrow testified Monday that supermodel Naomi Campbell named Charles Taylor as the person who presented her with a diamond. Farrow was testifying at the war crimes trial of Taylor, the former president of Liberia who prosecutors allege funded a brutal civil war in Sierra Leone using blood diamonds. A so-called blood diamond is mined in war zones and used to fund rebels and warlords. The stones have fueled bloody conflicts in Africa for more than a decade. Farrow's testimony at the United Nations-backed Special Court for Sierra Leone contradicted that of Campbell, who took the stand last week.
