Radiant Cut Lab Diamond Engagement Rings

Radiant lab grown diamonds combine a straight-edged, cropped-corner outline with brilliant-style faceting. They are worth considering if you enjoy the structure of an emerald cut but would prefer a livelier pattern of sparkle. Radiants can be nearly square or noticeably elongated, so compare their face-up dimensions.

Look closely at the facet pattern

Some radiants have broad flashes while others appear more finely textured. Neither pattern is universally better; ask to see photographs and video of the actual stone, paying attention to brightness across its centre and corners. The laboratory report can tell you about dimensions, colour and clarity, but it cannot show how you will feel about a particular pattern of light.

Consider the diamond's colour and clarity in context

Radiant cuts contain many facets, and their light pattern may make some inclusions less conspicuous than in a step cut of comparable size. This is not a reason to disregard clarity: examine the individual diamond and its report together. Warm metals can give the setting an entirely different character, while platinum or white gold emphasises its crisp outline. Try not to choose a grade without looking at the actual result.

A narrow solitaire band highlights the cut, while a halo gives its geometric outline greater width. Consider the position of the corner claws and the height of the setting, particularly alongside a future wedding ring. Compare the wider range in our radiant engagement rings.
