Emerald-cut diamonds are characterized by step cuts and a long table. Although emerald-cut diamonds are less brilliant than round diamonds or princess diamonds, they are revered for their clarity. Emerald-cut diamonds are known for their angled corners and step-cut, as well as their rectangular shapes. Because of their long table, inclusions are more easily seen on emerald shape diamonds than other more brilliant cuts. Emerald-cut diamonds are named as such because the cut was originally only used on emeralds.
Square-cut or Asscher-cut, diamonds are a popular diamond shape that are characterized by a step cut. This cut results in less light return when compared to their more brilliant alternatives, but offers a more vintage appeal. Square-cut diamonds feature cropped corners, which give it a unique, almost octagonal shape. Square-cut diamonds became very popular during the 1920s and as a result, are a desirable diamond cut for a vintage looking engagement ring.
Radiant diamonds are best characterized by their brilliance and facets. Radiant cut diamonds feature cropped corners (similar to a Cushion Cut) and brilliant cut (similar to a Princess Cut). Radiant shape diamonds are a great choice for people who like the square or rectangular shape the Square or Emerald but want more sparkle. Radiant cut diamonds tend to hide flaws better than Square or Emerald cuts because they are cut with many facets, whereas the latter cuts have large tables that easily show flaws.
