Traditionally, Claddaghs are expressions of love and friendship. Like most traditional symbols, the origin of the Claddagh has been obscured by the passage of time. It is almost certainly from the Irish fishing village of Claddagh, near Galway.
The Claddagh has become an enduring symbol of affection. The heart in the center of the design represents love, the hands that surround it represent friendship, and the crown at the top (if present) is symbolic of fidelity. Claddaghs are worn on the left hand, facing inward, if your heart is spoken for. If you are unattached, wear the ring on your right hand, facing outward.
