Radiant cut diamonds are fairly young, debuting in the 1970s. They’re similar to princess cut diamonds in that both are square shaped and cut for fire and scintillation. While princess cuts show diagonal lines when viewed from the top down, radiant cut diamonds have facets scattered seemingly every which way. The brightness of radiant diamonds is so concentrated that colored diamonds are often radiant cut to intensify their hues.
Like other square diamonds, the opposite sides of a radiant cut must be parallel to one another. You should also take care to ensure that the radiant diamond is mounted to prevent its corners from chipping. If you want your stone to really shine, consider a design that surrounds it with a halo of smaller diamonds. Your radiant diamond will live up to its name and more.
