A radiant halo engagement ring combines the beauty of a radiant-cut centre stone with the added sparkle and glamour of a halo setting. The centre stone is cut in a rectangular or square shape with trimmed corners, known as a radiant cut, and is surrounded by a halo of smaller diamonds. The halo setting is a popular choice for engagement rings as it enhances the overall appearance of the centre stone. The smaller diamonds in the halo create a frame around the centre stone, making it appear larger and more brilliant.
