Radiant shaped diamonds are square or rectangular cuts with an evenly cut-cornered edge. Its 70 faceted cut maximizes the effect of the color refraction through the stone.
The Radiant belongs to the Modified cut type. It is a cut created from a combination of two diamond cutting styles, the Round and the Emerald.
The Radiant is considered one of the most common shapes used with Fancy Color Diamonds along with the Cushion shape. Diamond cutters often prefer to cut the rough into Radiant or Cushion cuts since due to the structure of the diamond facets, these shapes enable maximum potential to show the diamond colors.
