Given as a symbol of a promise to love forever, eternity rings are a beautiful way to show the love of your life how much she or he means to you.
Eternity rings come in "full" and "half" designs. Full eternity rings have stones all the way around the band, and half-rings only have stones on one half of the band resulting in a more practical and less expensive ring. Full rings are somewhat impractical due to the thickness of the band, and the stones used must be fairly small and re-sizing them is difficult so they are mostly custom made.
Diamonds are the most commonly stones used on eternity rings but other gemstones are also used.
