Can I wear Engagement ring on any hand?

The purpose of an engagement ring is to tell the world you're "taken" and the world knows that by it sitting on your left ring finger.

I think what ever makes you comfortable is what matters. But people may not think your married when you wear it on your right hand. So its hard. But i think you should try to atleast break out of the habit of doing that. I do that too, i have a habit of putting my ring on my middle finger, but im getting better. I actually want to look married. So yea, i think you should try to break the habit!

Left-hand ring finger ONLY.

No it must go on the third finger of your left hand, unless you are in Russia, in which case it is the third finger of your right.

it's supposed to be on your ring finger on your left hand to symbolize the engagement/marriage
