GOODBYE COACH: Reed Krakoff isn’t the only one leaving Coach. Kerry Diamond, Coach Inc.’s divisional vice president of public relations and collaborations, is also exiting the company. Diamond, a former magazine editor, spent two years at the leather goods brand and today will be her last day. “I’m leaving to work full time on my restaurants and on Cherry Bombe, the magazine I’m launching with my friend Claudia Wu,” Diamond said in a mass e-mail she sent out Thursday afternoon.
