Radiant cut diamonds have the outline of emerald cut diamonds, but they show a far greater shine. They lengthen the finger and come at a bigger discount than round ones, making them a great choice for engagement rings. A very fine-cut sparkle can shine as bright as a round diamond, but it costs much less. Due to their relatively affordable price point, they are also popular for non-engagement jewelry such as diamond studs and pendants.
