The Ottoman Empire was noted for the quality of its gold- and silversmiths, and particularly for the jewelry they produced. Jewelry had particular importance as it was commonly given at weddings, as a gift that could be used as a form of savings. Silver was the most common material used, with gold reserved for more high-status pieces; designs often displayed complex filigree work and incorporated Persian and Byzantine motifs. Developments in design reflected the tastes of the Ottoman court, with Persian Safavid art, for example, becoming an influence after the Ottoman defeat of Ismail I after the Battle of Chaldiran in 1514. In the rural areas of the Empire, jewelry was simpler and often incorporated gold coins (the Ottoman "altin"), but the designs of Constantinople nevertheless spread throughout Ottoman territory and were reflected even in the metalwork of Egypt and North Africa.
