For more than two centuries, jewelers have worked in the district of Hockley, northwest of the city center; today around 200 manufacturing jewelers continue the tradition in the Jewellery Quarter, producing more than a third of the jewelry made in Britain. A free booklet from the tourist office gives you the lowdown on shopping in the area. The city's Assay Office hallmarks 12 million items each year with the anchor symbol denoting Birmingham origin. The ornate green and
gilded Chamberlain Clock, at the intersection of Vyse Street, Warstone Lane, and Frederick Street, marks the center of the district. Shops are closed Sunday. The quarter is two stops along Metro Line 1 from Snow Hill Station.
