What is the prettiest cut diamond?

There is no single prettiest cut of diamond, as the visual appeal of jewelry is a matter of personal preference. If you love the sparkle of diamonds, brilliant cuts like the round, cushion, radiant, princess, pear, oval and marquise may appeal to you. Step-cut styles, which include Asscher, emerald and baguette, allow the beautiful color of a gemstone to take center stage. Find a large collection of diamond jewelry on 1stDibs.
