Supermodel Naomi Campbell told the war crimes trial of Charles Taylor today that she was woken in the night and given a pouch containing "small, dirty looking stones" after a charity dinner.
Giving evidence to the trial in The Hague, Netherlands, Campbell said she met Taylor for the first time during a meal in September 1997.
She told the court that two men knocked on her door in the middle of night as she stayed at the home of former South African president Nelson Mandela and presented her with a pouch containing gems.
"They were very small, dirty looking stones," she said.
The model told the court she discussed the incident with fellow guests the next morning and was told: "That's obviously Charles Taylor."
Campbell is said to have received a "blood diamond" from Taylor, who faces charges including criminal responsibility for murder, rape, sexual slavery and the use of child soldiers.
The 40-year-old model, from Streatham, south London, refused to take part in the trial at the Special Court for Sierra Leone in The Hague until she was issued with a subpoena.
She arrived at the courthouse in The Hague surrounded by police officers. She did not speak to reporters outside.
Campbell said she was told the stones were "probably" diamonds but did not know for sure
She said she "assumed" they were a gift from Taylor.
"I didn't know anything about Charles Taylor," she said. "I had never heard of him before, never heard of Liberia before, never heard of the term 'blood diamonds' before, so I just assumed it was."
She said she did not know who presented the gift.
"I didn't know if it was staff of the house," she said. "I didn't know where they came from."
The model added that she had not wanted to attend the hearing and described it as an "inconvenience".
"I don't want to be here. I was made to be here... This is an inconvenience to me," she said.
She was reluctant to attend because she wanted to protect her family, she said.
Despite believing the stones were a gift from Taylor, Campbell had no intention of thanking him.
She said: "I had no way of contacting him and I had no intention of contacting him."
Campbell said she had "read up" on Taylor using the internet and learned that he had supposedly "killed thousands of people".
"I don't want my family in danger in any way," she said.
She said she had given the stones to a colleague and added: "Once I handed them over... it was out of my hands."
Campbell said the stones were "very small" but could not offer any further detailed explanation of them.
"I'm not a diamonds expert but they were very small," she said.
Campbell said she was not a "boastful person" and denied flirting with Taylor during the dinner.
"When I am with Nelson Mandela - and I think everyone in the world feels the same way - my focus and attention is on him," she said.
Under cross-examination, she also denied speaking directly to Taylor on the night.
"I spoke in general," she said. "I was interested in him. I had never heard of Liberia before. He said that he was the president of Liberia."
She said she was not involved in any conversations at the dinner table about diamonds.
"I was sat beside Nelson Mandela and if there was a conversation about diamonds, it wasn't with me," she said.
