Big Little Lies star Zoe Kravitz employed a similar jewelry strategy by balancing her Dior Haute Couture gown, adorned entirely in black and rainbow-colored feathers, with a neat, tailored double diamond choker and other understated diamond pieces from Tiffany & Co.

Presenter Jessica Biel floated onto the red carpet in a languid, glimmery goddess gown straight from the Ralph & Russo runway. She and stylists Rob Zangardi and Mariel Haenn grounded her look with some serious diamonds—geometric dangle earrings, a bypass ring and a blindingly gorgeous riviere bracelet, all by Forevermark.

A notorious red-carpet risk-taker, Project Runway host Heidi Klum gobsmacked jewelry lovers with her choice of saucer-sized hoops and stacks of wide bangles (the arm party on each wrist extended to her forearms). The supersize scale of these Lorraine Schwartz pieces, plus the fact that they were made of wood and diamonds, made this a boho chic moment writ large.
