Usually our Marie wear her wedding ring on her right hand and her engagement ring on her left, in accordance to what is most common in Denmark.
According to tradition the engagement ring is closest to the heart, while the the wedding ring is on the hand you use when you swear on something.
There are probably other variants of that story, but that's the one I know of.
ADDED: Checked a picture. I actually think you are right, ldmemail.
