The Claddagh Ring is the oldest traditions that’s widely known. The traditional ring given by young Irish men to their girlfriends as a gift, and sometimes it’s inherited from a family member. But the ring has a part in wedding ceremonies, too.
Single women traditionally wear the ring on the right hand, with the ring facing outward. When in a relationship, it’s turned inwards, indicating that the lady isn’t ‘available.’
But the ring is moved to the left hand when the wearer becomes engaged (point outward), and turned inward on that hand once married.
The symbolism attached makes the Claddagh a popular engagement or unusual wedding ring!!
