This is an old ivory finger ring from the Dinka people, a Nilotic ethnic group living in South Sudan. They mostly live along the Nile River, from Mangala to Renk, in regions of Bahr el Ghazal, Upper Nile, and the Abyei Area of the Ngok Dinka. They are known for their marriage rituals and cultural demonstrations in various ceremonies. Such rings were worn by Dinka elites. Dinka men wore ivory rings with short knobs, usually decorated with the circle-and-dot motif. Frequent use often flattened the band on one side. These rings were considered ivory arm ornaments and were mostly worn on the left hand, as the right hand is used for eating. Dinka finger rings indicate status and are worn by men only. This ring has a wonderful aged patina with typical decorative markings and shows signs of usage, wear, and natural abrasion.
