The reason? I married my wife in a Ukrainian Orthodox church and have never felt the need to move it even though we live in a country where 99.99% of people wear it on the left hand.

My ring is a small silver metal band that maybe cost $20.  Nothing to brag about.  Yet it has been the subject of hundreds of conversations over the last 8 years because of its placement.

That's the power of jewelry–for better or worse it sends signals about who we are, what commitments we have made, and our status in society.   

Step outside the norm and people notice.  Depending on your goals, this may be a good thing or a bad thing.
