There are many options available for designing engagement rings with side diamonds. For instance, consider a three stone diamond ring setting. In this diamond ring design, a gemstone of decent size will be flaunted at the center of a ring by means of a prong or bezel setting. Additionally, the center diamond will be flanked with accent diamonds of similar or smaller size on either side. This type of setting will be perfect for enhancing the size of your sparkler or to highlight the main gemstone. Halo is the most popular diamond ring setting so far. In this type of designs, a small or medium-sized diamond is encircled with a layer of tiny diamonds. Usually, all the gemstones here will be held in place using a bezel or a prong setting. A halo setting is perfect for enhancing the size, sparkle, and overall appeal of an engagement ring.
