This pair of large, ‘C’-form anklets is from Tunisia or perhaps Libya. They might also be of Nubian origin. They are of heavy, solid silver. The two have been contoured so that they are more comfortable to wear, given their weight. They have been engraved or incised with geometric motifs.
A related pair, illustrated in Nadler (2005, p. 69), is attributed to the Berbers of Tunisia.
The pair has excellent wear and patina, and is in fine condition.
