As its name might imply, the radiant-cut diamond is a diamond designed for the most radiant woman. Celebrities from Drew Barrymore to Megan Fox have all donned the radiant-cut diamond on their ring finger, and it’s no wonder! Radiant-cut diamonds are similar to princess-cut diamonds, but were actually created first. Their beauty is derived from the fact that both the crown (the top of the diamond) and the pavilion (the bottom of the diamond) have a brilliant-cut facet pattern that directs the light to create a uniquely vibrant effect.
