This pair of ‘C’-shaped cuff bracelets is from the Gurunsi people of northern Ghana & southern Burkina Faso. They have been cast in bronze and are decorated with triangle, plaited rope and other motifs.
The two are not identical but most probably are and were worn as a pair.
An almost identical single example is illustrated in van Cutsem (2002, p. 57).
The two here have splendid wear and patina. Their contours have been softened from age and handling. They have a pleasing dark coppery hue. They are both decorative and sculptural.
