A radiant diamond can just as easily anchor a solitaire ring as it can sit as the center of a three-stone design flanked by trapezoid or baguette side stones. Which route you take often comes down to how much visual weight you want the center stone to carry on its own versus sharing the spotlight with complementary side stones of the same shape and finish.
For example, a 0.37-carat, IGI-certified, Ideal cut, I color, VS1 clarity radiant diamond is priced around $206. At this size, clarity and cut precision start to carry more of the price than carat weight alone, since inclusions become slightly easier to spot as the stone grows in size and surface area, especially near the center facets.
VS1 clarity holds up nicely here, keeping the stone looking clean without paying extra for a grade that wouldn’t be visible to begin with. Cut quality deserves just as much attention, since a well-proportioned radiant makes the most of every bit of its clarity and color grade combined, from every angle and in any light, indoors or outdoors.
Prong style is worth thinking through carefully with this shape. Four sturdy prongs at the corners tend to offer the best mix of visibility and protection for a radiant of this size and weight, day-to-day, without much added cost, complexity, or ongoing maintenance.
