This ‘C’ form silver bracelet is of high-grade silver. Its sides flare out and it is decorated in niello black enamel work with vegetal scrolls.
Also, there are prominent applied cone-form bosses of coiled silver wire and green and orange enamelwork. The bosses have been attached by silver rivets.
See Amel (1998, p. 285), and Rabate (2015, p. 59, p. 93) for related examples.
The example here has plenty of signs of age and has no obvious losses.
