The halo engagement ring design features one, or many frames of smaller diamonds around the ring's center stone, often secured in a prong setting. Halo rings can be round or squared off on the sides. This style offers security and can also make the center stone appear larger! Halo engagement rings featuring halos of diamonds or other gemstones encircling a center gem were designed at least as early as the Victorian era and were popular in the Art Deco and Retro eras as well. Growing in popularity, halo engagement rings in rose gold are becoming a sought after style because of their romantic look.
