Eternity rings have been called many different things throughout the generations and they have come to represent many different things to people. Wedding rings, on the other hand, have a single universal purpose. They are used to signify the union in marriage between a man and a woman. With that being said, both wedding rings and eternity rings have been used in the same sense when being exchanged by couples during wedding vows. Beyond the more familiar types of rings associated with weddings, such as engagement rings and wedding bands, you will find new styles of diamond jewellery such as beautiful eternity rings.
