The Claddagh ring is by far the most popular Celtic jewelry item. Claddagh rings are a traditional ring given in friendship or worn as a wedding ring. The design and customs associated with it originated in the Irish fishing village of Claddagh, located just outside the old walls of the city of Galway. The Claddagh ring was first produced in the 17th century during the reign of Queen Mary II, though elements of the design are much older.
When worn on the right hand, with crown and heart facing out, the Claddagh ring signifies that the wearer's heart is yet to be won. When in love, it is worn on the left hand with the heart and crown facing inwards. The crown and heart facing inwards on this hand declare to all that the love of your life has been found and you shall never be parted.
