Just speaking from experience, anything that looks like it is a nice wedding or engagement ring, if worn on either left or right hand will discourage single men from approaching you. The whole "put a ring on it" really does effectively send a message to the opposite sex about your availability. Just FYI if this is not a message you intend to send. I never thought about this until I got my engagement ring which I sometimes wear on my right hand and I joke about it to my husband that it really is a man repeller...to which his response was, the nicer the ring, the more effective the message, "beware! This woman is a lot of work! Stay away!" Lol.
