It was a night full of white roses, jewels, and some of Hollywood’s biggest stars at Bulgari‘s “Decades of Glamour,” which kicked off the 2014 Academy Awards and celebrated 130 years of — you guessed it — glamour. “They’ve been around for more than a hundred years and their stuff from the archives is amazing. They continue to be strong and the modern stuff is really incredible as well,” says Naomi Watts, the host of the evening’s party. The space at the Soho House on the Garden Terrace in West Hollywood displayed various Bulgari earrings and matching diamond necklaces, mixed in with framed portraits of A-listers who have worn pieces from the famed jeweler at numerous red carpet events—including Watts herself, Sandra Bullock, Anne Hathaway, and Nicole Kidman.

Joining the host—who added a colorful vintage Bulgari necklace to her black strapless Altuzurra dress—were fellow actresses including Emmy Rossum, Ashley Greene, and Kate Hudson, who also wore pieces from the Bulgari collection in honor of night. “There’s something about it that for me [is] iconically ’70s—I love ’70s—and they still sort of hold onto that,” Hudson explains to InStyle.com. “They’re just a great jewelry house and their stones are incredible. The colors are just beautiful, they really know what they’re doing.” As for Hudson’s choice of jewels, she picked a stunning Bulgari pendent necklace that matched her bold Emilio Pucci ensemble. “I love yellow,” says Hudson. “Yellow’s a happy color.” To see more stars from the diamond-studded party, look through our gallery!
