The center princess-cut stone is secured in a classic four-prong setting that highlights its crisp edges and brilliant faceting. Two pear-shaped side stones are positioned gracefully on each side, enhancing the overall sparkle and adding a soft contrast to the strong square center.

The shoulders feature delicate accent stones that provide additional brilliance while maintaining a clean and balanced profile. The gallery structure is carefully designed for both visual appeal and structural strength, ensuring secure stone setting and reliable casting results. The shank includes a smooth inner band for comfortable everyday wear.
