On his right pinky, jewelry designer James Taffin de Givenchy wears a ring bearing the Givenchy family crest. As the nephew of Hubert de Givenchy, he keeps the family’s history close in his Manhattan apartment, too, with a 753-page leather-bound book from 1926 that traces his lineage back to about 1300. As outlined in the new 400-page tome Taffin: The Jewelry of James de Givenchy, out tomorrow from Rizzoli, de Givenchy gravitated to jewelry rather than clothing, taking a job in Christie’s West Coast jewelry department after graduating from the Fashion Institute of Technology. Later, he worked at the fine jeweler Veradura as vice president. Twenty years ago, he launched his own jewelry company, Taffin. Critics have compared his sophisticated designs to European jewelers like Fulco di Verdura and Jean Schlumberger. The new book showcases over 300 pieces created by de Givenchy over the years.
