Oscar nominees Leonardo Dicaprio, Djimon Hounsou and Ryan Gosling were among the stars making a subtle diamond trade protest at the Academy Awards last night (25FEB07). The three actors wore red teardrop pins after agreeing to model the Amnesty International symbols aimed at raising awareness about diamonds mined in war zones. DiCaprio and Hounsou were both nominated for their roles in BLOOD DIAMOND, which further highlights the issue of gem-mining in global trouble spots. Meanwhile, Gosling plans to auction off his pin to raise cash for a Ugandan burns victim he recently met. Speaking on the red carpet last night, the actor said, "Her name's JOYCE. I met her a week ago. Eighty per cent of her body is covered in burns. She was wrapped in a carpet and set on fire. This is an example of what's going on in northern Uganda.
