After 20 years in the Wabash Jewelers Building, Chicago Diamond Center, a family-owned jeweler, has moved to the historic Pittsfield Building, now home to more than 30 fine jewelers. Built in 1927 and granted Landmark Status in 2002, the 38-story professional office building exhibits the unique characteristics of those skyscrapers that first began to shape the Windy City’s distinctive skyline in the early 1900s.
