I come from a culture where rings don't mean much but am right now in US and trying yo figure out which ring goes where? I understand the engagement ring is a big deal and goes on left hand ring finger but not sure of others. Like eternity band? 3 stone ring, 5 stone ring, colored rings, wedding bands? Does it really matter which ring is on which finger, I don't want to be laughed at for wearing the wrong ring on wrong finger. Ty
