-The classic round shape is the most popular. Like a wedding band, the circular shape of the diamond represents love without end. Women who prefer it are usually drawn to its traditional romance, and they themselves are honest and faithful, and halo setting refers to the placement of diamonds or other gemstones in a concentred square around a center stone. The halo setting makes the center stone appear larger—a great option to boost the appearance of a small diamond—and it increases the overall sparkle of the ring. They come in various interesting shapes, some of them even look like flowers. This halo is paired with pavé band. Extremly sparkle and elegant piece!
