No wonder, an infinity diamond engagement ring is one of the most preferred choices these days. Some of the amazing designs for such diamond rings are given below. Infinity Diamond Ring Band In this design, the main attraction is an 18k rose gold diamond ring band that is patterned with infinity designs. In order to lift up the overall sparkle of the ring, the entire band is paved with melee diamonds and a sapphire stone is bezel-set at the center of the ring. Pear Cut Infinity Diamond Engagement Ring This is one of the stylish options for infinity diamond rings. In this design, a platinum band flaunts a huge infinity design at its center. To raise the overall elegant quotient of the ring, a pear cut diamond of decent size is given at one of the infinity knots.
