I stumbled across this Q & A at The Knot and it made me realize that many people don’t understand the basics when it comes to wedding and engagement ring etiquette. This answer provides you the general rules:
I’m clueless when it comes to engagement ring and wedding ring etiquette. Do I have to have a wedding ring, or could I just continue to wear my engagement ring after I’m married?
Though there’s not necessarily a correct way to do it, most married folks do wear their wedding rings at all times (with or without their engagement ring). After all, it’s a symbol of your love, devotion, and, well, the fact that you’re no longer engaged — you’re married!
Our advice? Choose a wedding ring you love and won’t mind wearing all the time. It doesn’t have to be a perfect match with your engagement ring. You can choose to wear your wedding ring and engagement ring together on your left hand; wear your wedding band on the left and engagement ring on your right; or just wear your wedding ring. (Many women choose not to wear their engagement rings all the time simply because their setting could snag on clothing, among other reasons). If you really love your engagement ring, you should wear both rings. That way, you can still show off your engagement ring, and your happily wedded status.
