Medieval English gold ring ca 1350-1400. Universally called stirrup rings, but this name is a 19 th century description denoting the shape of the ring that reminds one of an early form of stirrup. They are mainly set with cabochon sapphires and have been found in eary graves worn by Bishops. Sapphires were un cut to remind the wearer to the natural God given beauty of the heavens. In some ways the heavy symbolism makes these rings devotional jewellery.
