It’s not unusual to see a starlet rocking a mess of diamond chains and crosses, but we really love what Rihanna’s doing here: pairing her tough girl jewels with a sweetly feminine dress and toned-down hair and makeup. Talk about balance.

We always love Nicole Richie’s late Seventies hippie chick look — a vintage-inspired headpiece is the perfect topper for this modern-day Stevie Nicks style.

Kim Kardashian knows how to attract the right kind of attention, and her sparkling disc earrings certainly draw all eyes straight to her face. It’s not a new trick: for ages, women have been wearing jewelry for its skin-flattering effect.

Emma Roberts’ aunt Julia has a quirky style, so it’s no surprise that this young actress has a totally individual look, too. We love her retro-inspired jeweled flower necklace, which would look just as good over a tee as it does with a party dress.

Emmy Rossum’s mix of high (gem-covered necklace) and low (jean jacket) should remind us of an important styling trick. We all have a few precious accessories in our closets, and wearing them with an everyday outfit makes for a truly modern look.

Every off-screen move Penelope Cruz makes is graceful, elegant and just plain stunning — kind of like these classic diamond hoop earrings.
