The radiant cut diamond also looks wonderful in an array of engagement ring settings, whether it is used as a single stone or is surrounded by accent diamonds. Of course, whether you want a solitaire style ring or one with diamond accents is a personal choice much like the diamond cut, to begin with. Besides, look into these aspects to make the most of radiant diamond ring settings. The length to width ratio of the radiant cut gem is what determines how rectangular its shape will be. If the ratio is between 1.00 and 1.05, then it will produce a square shape. If you want a rectangular radiant cut diamond, then make sure the ratio is from 1.30 to 1.50. The radiant cut stone has clipped corners, similar to one with a step cut, but has brilliant facets. It is an ideal cut choice if you are looking for plenty of fire and clean lines.
