Beautiful ring but I believe Jan has the wrong information. My Claddagh is my wedding band. Wear it up right (top of crown towards your fingernail bottom of heart towards your knuckle) to show you are taken on the right hand or married on the left hand. If you are single it should be worn on the right hand with the crown "upside down" top of crown towards knuckle, bottom of heart towards nail. I hope this helps.

When wearing your Claddagh ring and the crown is facing twards your heart then you have found your true love and you are spoken for, when the crown is facing twards your fingernail it means you are single.
