In the 14th – 18th centuries in Europe, alongside locally produced amber works, there were also imported items decorated with amber, such as furniture, mirrors, boxes, tableware and cult necessities (crosses, rosaries, altars). Amber was seen not as a material for jewellery items, but as a valuable material to be used for decoration only. Amber crafts guilds were concentrated in Königsberg, Danzig, Lübeck and Brugge. Famous German master craftsmen have created many art works of this kind (Georg Schreiber, Jacob Heise, Nicolaus Turrow, Gottfried Wolffram, Christoph Maucher).
