The diamond-ring decision is as exciting as it is weighty: Not only is this precious gem a significant expense, it also becomes a lasting symbol of your love. The shape of the stone conveys your style (oval and round shapes tend to be classic; emerald and square, more contemporary; pear and marquise, retro-chic). Take a look at these gorgeous rings to learn what style is right for you!
