It's been said that trying someone's engagement ring on your left ring finger is bad luck for single women. Why? I'm not sure, but even though I know it's just an old wives tale, it's one superstition that I don't want to test! Since I love to try on engagement rings, I always slip them on my right hand, just in case. But what about you? Ladies, do tell, when you try on your a friend's engagement ring, do you put it on your right or left hand?
