How a hard-charging CEO is changing the world’s largest jewelerIf you want to see the epicenter of the jewelry business, visit Signet Jewelers’ headquarters in Akron, Ohio. The 500,000-square-foot campus houses 2,500 employees—all of whom do the not-so-easy work of supporting the company’s U.S. retail division, Sterling Jewelers, which totals 1,954 stores, including such varied brands as Kay Jewelers, Jared the Galleria of Jewelry, outlets, and regional stores, not to mention the company’s growing e-commerce presence. (Signet also owns 511 stores in the United Kingdom under the Ernest Jones and H.Samuel labels.)
