Traditionally, the Eternity Ring was usually worn between the wedding ring and the engagement ring on the ring finger of the left hand to connect them. This can be traced back to an ancient belief that the Vena Amoris (Latin for 'vein of love') flows through the left ring finger and provides a direct connection to the heart. However, this tradition cannot be proven exactly and there are many cultures that wear wedding and engagement rings on other fingers as well and give the same reason. In the end, therefore, it doesn't even matter what the tradition says, as long as you follow your own symbolism and feel-good factors. Eternity rings also look wonderful on their own or on another finger or can be combined very well with other rings. In the end, it's what you like and what feels right that counts.
