What’s new for 2016? Instagram and Snapchat—once strictly social networks—are becoming ­viable retail channels. Man-made diamonds are ­moving into the mainstream. And we hear earrings are big. Really big. Statement Earrings Clothes may be the reason high-profile runway shows exist, but jewelry still steals the spotlight on occasion—like during the 2016 spring shows. Metallic danglers at Rosie Assoulin, side-facing tribal hoops at Marni, and metal-and-stone pairings at Loewe proved fashion is a firm believer in “Go big (on the lobes) or go home.” Not that jewelry designers need to be reminded of the merits of massive ear mobiles. “Spring fashion tends to be less structured,” says Amanda Gizzi, director of public relations and special events at Jewelers of America, “and oversized earrings are a fun way to bring the focus back to the face.” —Jennifer Heebner Ri
