Features

The Radiant Cut is a unique and fusion cut comprised of usually seventy facets together with specific trimmed edges. Square-shaped Radiant cuts typically have ratios around 1.00 – 1.05 whereas rectangular Radiants may have ratios from over 1.05 up to 1.50. Its versatile configuration incorporates both the brilliance and depth of a round brilliant , an Emerald and a Princess cut making it one of the best options for all kinds of jewelry.

Because of its extra facets, the Radiant cut can distribute more light through the stone making it one of the most brilliant of all square- and rectangular-shaped stones. It can also hide some inclusions more efficiently than other shapes.
As it is a patented cut, it may be termed as a Cut-Cornered Square on a laboratory certificate (eg. GIA or AGS), or a Rectangular Brilliant if it has a ratio greater than 1.05.
