Jewelry at the Oscars

Diamonds and platinum once again ruled at the Oscars, but a few celebs, like Heidi Klum, used colorful jewelry to accent their red carpet ensembles -- Heidi's red dress is in sync with her work to help raise awareness for women's heart health. Angelina Jolie, Amy Adams and Phoebe Cates all accessorized with bold, colorful jewelry, and Freida Pinto's diamond drop earrings were reportedly vintage pieces from her native India. Mickey Rourke chose one piece of jewelry for a sentimental purpose -- his necklace included a photo of his 18-year old Chihauhau, Loki, who passed away a week ago.
