These three, different, large and sculptural anklets are of silvered cast bronze and silver alloy.
Each is beautifully cast with motifs to suggest interlocking chainwork, bells and so on.
The two smaller examples have small grains inside so that the anklet would rattle when the wearer moved.
Each has wear and obvious age.
See Hoek (2004, p. 143) and Ghose (2016, p. 201) for related examples.
