I agree that it depends on where you live. A friend of mine is Irish and she wears her rings (wedding and engagement) on the ring finger of the left hand like most Americans, but her dh is Dutch and he insists that it should be worn on the ring finger of the right hand. And I may be mistaken, but I believe that in some cultures the engagment ring is worn on one hand, but after the marriage it is moved to the other hand.
