It doesn't suck to be a fashion scion. Since Gaia Repossi's great-grandfather founded his eponymous jewelry line in Turin, Italy, in the '20s, the Repossi name has been interchangeable with luxury. Under her father Alberto's direction, the house became the official jeweler of Monaco's royal family. (Charlene Wittstock's engagement ring is a Repossi original, and it was rumored that Dodi Fayed was to propose to Princess Diana with a Repossi ring.) But Gaia, just 25, takes a fresh approach to designing bijoux burning precious metals and fully covering fingers and ears in modern works of art. The pieces, often spotted on Repossi's front-row-fixture friends, marry the Old World with the New their glamorous history written in the filigree.
