Devoted to the history of jewellery, the Schmuckmuseum Pforzheim (Pforzheim Jewellery Museum) is the only museum of its kind worldwide. Some 2000 exhibits, including an extensive ring collection, reveal the vast diversity of jewellery over five thousand years. The collection on permanent display focuses on treasures from Greco-Roman antiquity, the Renaissance and Jugendstil/Art Nouveau as well as contemporary art jewellery. The history of the jewellery industry in the "golden" city of Pforzheim is also surveyed. In addition, visitors can continue to rediscover the Museum at regular special exhibitions.
