The folks at Pomellato clearly have a knack for picking partners. The Italian jewelry brand tapped brainy style icon Tilda Swinton to appear in its 2010 ad campaign; for the holiday season it has teamed up with Bergdorf Goodman to offer an exclusive preview of its spring Tango collection. Two rose gold bangles (below) and two rings—some embellished with brown diamonds—will be available exclusively at the New York department store in December, several months before arriving anywhere else. As excited as he is by the collaboration, Pomellato managing director Andrea Petochi sounds even more thrilled that he’ll have something new to bring home in time for Christmas. “My wife is addicted,” he says, laughing. “It’s become a problem” (at Bergdorf Goodman, New York; from $3,455 to $28,500).
