The 70 facets in a Square Radiant cut diamond allow it to emanate a tremendous amount of shine, it is a nice bridge between a cushion and a princess cut, and for that reason looks beautiful set with both rounded or square cornered diamonds.
The GIA gives this diamond cut a name on its certificates that is a bit of a mouthful: “Cut-Cornered Square Modified Brilliant”. This is a detailed way to describe the specific way the diamond is cut. In the diamond trade we simply use the term “Radiant Cut” to describe this particular diamond cut.
There are a number of variants in this cut design, so don’t assume all are the same. The configuration of the faceting on these diamonds can vary from diamond to diamond. There is no “rule” that applies to the way the cut should be faceted.
From a ring design point of view, these diamonds are often used in halo rings and are very suitable in “Art Deco” styles, having a very geometric outer shape. It is a cut type better suited as a centre stone in a ring.
