This sculptural pair of rings made for each of the two big toes, is of silver that has been gilded (gold plated).
They would have been worn by a woman in either Yemen or Oman and are based most probably on an Indian prototype.
They are of hoop form, with rounded tops and a flat base. The hoops are decorated with bands of fine granulation work of varying sizes and forms, and each has then been topped with a loop from which three gilded silver bells are suspended.
The pair is in fine condition with no losses or repairs.
