eternity engagement ring

A coworker of mine has a beautiful alternative to the traditional engagement ring; her engagement ring SET is comprised of a diamond eternity band and two different gold bands.  So beautiful!  I love this idea, especially if you are a little non-traditional and don't absolutely love the idea of a large diamond spinning around on your finger.  A diamond eternity band can give you just as much sparkle and 3 different styled rings is such a beautiful way to make them all your own.  I'd start with this rough diamond eternity band and add on from there!
