This is a very special vintage Fede ring!  Crafted from solid 18ct Gold, and marked as such on its interlocking rings, it features two hands, joined together in union, which open to reveal a small gold heart.

The meaning of 'Fede' is best described from the Latin phrase, “mani in fede,” which means hands clasped in faith'. It was symbolic of faith and trust - and was used as an engagement ring. In celtic areas, the same ring was called a Gimmel (twins) ring.
 
This ring is currently a UK size K 1/2, which is a US size 5 1/2.  It weighs 4g of 18ct Gold and is in excellent vintage condition.
