This interesting ring, made for a woman, is from the Bedouin people of Yemen.
It is decorated with granulation work and applied flattened disks. The bezel is raised and set with a red stone.
Related examples are illustrated in van Cutsem (2000, p. 99).
The ring here is stable, wearable, and has clear age. The contours of the ring and the applied decoration have all been softened from years of handling and wearing. It is heavy for its size.
