Halo setting is a popular style especially in engagement ring designs. A halo setting features a circle of smaller diamonds or gemstones that surround the center stone. It can come in various shapes, such as round, heart, cushion or pear, and is often used to create a stunning and shinier look. Moreover, this distinct design enhances the brilliance and perceived size of the center stone, which means it makes the center stone look bigger and more glamorous.
