The most beautiful examples of Jablonec costume jewellery can be found in the local museum. The collections are so comprehensive that three buildings are needed to house them. Exhibitions of glass, medals, pearls, buttons and other accessories are gathered together in a wonderful Art Nouveau building just outside the town centre. If you are particularly interested in jewellery, head for the Belveder Gallery. There’s also a small glass museum in the former glass producing hamlet of Kristiánov, one of the highest situated in the Czech Republic. You can also learn the secrets of the costume jewellery production process at the Pesničák workshop in Josefův Důl or try your hand at glass pearl polishing in Pěnčín.
