A platinum cushion-cut engagement ring looks like a pillow-like diamond nestled on a sleek and classy metal, giving it the ultimate softness. This ring setting is not particularly loud due to its metal but looks absolutely stunning with its timeless quality. Platinum is a sturdier metal that will last longer than other metals, making it richer in its appearance. The cushion cut displays broader facets with rounded sides, reflecting light and fire with great brilliance.
