These two silver pendants are from the Nubian people of Sudan.
Both feature a trapezoid-shaped plate with a saw-cut upper border attached to a silver tube through which a chain or leather cord could be threaded to allow for suspension from the neck.
Each is etched with naive, geometric motifs.
Both examples have superb age and wear from many years of handling and being worn.
Similar examples are illustrated in Fahmy (2007, p. 120).
