"When I was sleeping I had a knock at my door and I opened my door and two men were there and gave me a pouch and said: ´A gift for you´," the model told the court, dressed in a classical, beige two-piece with a knee-length skirt.[break]
Her long, straightened hair was swept back in a stylish bun, and she wore a sparkling, choker necklace.
Campbell said she left the pouch next to her bed, went back to bed and opened it the next morning.
"I saw a few stones in there. Very small, dirty-looking stones," she said, adding "there was no explanation, no note".
The model told judges she "would not have guessed right away" that the contents of the pouch, "dirty-looking pebbles", were diamonds.
"I am used to seeing diamonds shiny and in a box, you know."
At breakfast that morning, Campbell said she told her then modelling agent Carole White and actress Mia Farrow about the gift.
"One of the two said that is obviously Charles Taylor and I said: ´Yes, I guess it was´."
Prosecutors of the Special Court for Sierra Leone have called Campbell, 40, to the stand in a bid to disprove the former Liberian president´s claim that he never possessed rough diamonds.
They say that Taylor, 62, had men deliver at least one so-called "blood diamond" to Campbell´s room after the two met at a celebrity dinner hosted by Mandela, then South African president.
Taylor allegedly took the diamonds to South Africa "to sell ... or exchange them for weapons".
Accused of seeking to "take political and physical control of Sierra Leone in order to exploit its abundant natural resources ... diamonds", Taylor has denied the claims.
Campbell said she gave the stones to a friend, an official of the Nelson Mandela Children´s Fund, "to do something with".
"I didn´t want to keep them," she said, adding there were "maybe three, two or three," stones in the pouch.
She added she never saw Taylor again and never confronted him about the gift, which she said she had not found strange.
"I get gifts given to me all the time, at all hours of the night," she told the court, adding that "it is quite normal for me to receive gifts."
White and Farrow, who both attended Mandela´s dinner, are to testify about the gift next Monday.
