Round cut diamonds are both the most popular and the most expensive shape. Maximise your budget by considering the nine fancy shapes, including princess, emerald, Asscher, cushion, marquise, radiant, oval, pear, and heart.
Round diamonds are a classic shape and complement every style of engagement ring available at Blue Nile. Keep it simple with a traditional solitaire ring, or enjoy maximum sparkle with a halo ring style.
Most customers choose a centre stone of just under one carat, but you can choose any carat weight for your engagement ring.
