Diamonds may be a girl’s best friend, as the song goes, but the luxury jeweler Tiffany & Co. is Leigh Harlan’s best buddy. The company announced it will promote Harlan from associate general counsel to senior vice president and general counsel in charge of global legal affairs on May 22.

Harlan replaces Patrick Dorsey, 63, who is retiring after 29 years with the company, according to Friday’s announcement and the company’s filing with the U.S. Securities and Exchange Commission.
