Radiant diamonds combine symmetry, fire, and brilliance to offer, in one stone, the best traits of round and princess cut diamonds.  This stunning 1.5-carat radiant diamond from Blue Nile is an excellent example of the alliance of form, function, and fire in radiant diamonds.

What is a Radiant Cut Diamond?

As a member of the mixed-cut family of diamonds, a radiant diamond has 70 facets compared to 58 in the modern round brilliant. All these facets make radiant cut diamonds, as the name suggests, radiant.

Radiant diamonds also bring exceptional form as well. Trimmed corners allow for greater versatility when used with a wide range of settings, offering exceptional brilliance regardless of the design.

1.50-Carat Radiant Cut Diamond Blue Nile

Radiant cut diamonds offer a hybrid between shape and brilliance. Since round cut stones have the highest luminance, radiant cut stones bring a different symmetry but with similar fire and brilliance. Radiant diamonds also cost 20-39% less than round diamonds – compare this radiant diamond and this round diamond from Blue Nile.  These characteristics make them ideal for a diamond engagement ring that will truly stand out.
