The city's role as a world diamond centre can be explored at the Diamantmuseum. With an English-language audio guide in hand, start on the 3rd floor and let one of seven virtual guides assist in your quest for the perfect stone. The whole thing is very Antwerp - from the sultry fashions worn by the guides to the proud exhibits showing diamond-studded jeans. There's a special 'touch route' for visually impaired visitors.
