Radiant Cut Diamonds: Shape, Sparkle and Ring Settings

A radiant cut diamond combines a square or rectangular outline with cut corners and a brilliant style of faceting. It is worth considering if you like an angular shape but prefer a different pattern of reflections from an emerald cut.

Look Beyond a Single Ratio

Radiants vary in length and width. A more elongated stone looks different from a nearly square one, but a particular ratio is not a guarantee of beauty. Compare the actual diamond in motion and in several lighting conditions rather than choosing from table and depth percentages alone.

Keep the Shapes Straight

The original gallery includes other shapes. The oval halo and marquise shaped rings below are retained as comparisons, not labeled as radiant cut examples. For any stone whose outline is unclear in a photograph, check its grading report and a clearer view.

Evaluate the Stone and Setting Together

Look for an appealing outline and light pattern, then review color, clarity, measurements and origin in the report. No clarity grade automatically promises that every inclusion will be invisible to you. Inspect the individual diamond at a normal viewing distance.

Try the proposed setting to check its height and how it sits next to a wedding band. Discuss prong placement and stone security with a jeweler. Cut corners do not make a diamond immune to damage.
