(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.
During her appearance, Campbell said she didn't know who sent her stones, which were delivered to her room in Pretoria, South Africa late at night.
But Farrow told prosecutors: "She said that in the night she had been awakened. Some men were knocking at her door. They were sent by Charles Taylor and they had given her a huge diamond".
Both Farrow and Campbell were guests at a dinner hosted by Nelson Mandela in 1997, which Taylor also attended.
The next morning, Campbell told the tribunal, she shared the story of receiving stones with her then-agent, Carole White, and Farrow. CNN
