A radiant cut diamond has the rectangular outline and trimmed corners of an emerald cut with the brilliant-style faceting of a round. The result is a sleek, angular shape that sparkles as intensely as a round brilliant.
Radiant engagement rings suit buyers who like the geometry of an emerald cut but want more fire, who want a shape that hides inclusions well, and who want a stone that reads large across the finger. Radiants look sharp in a solitaire, dramatic in a halo and balanced in a three stone ring with trapezoid or tapered baguette sides. Elongated radiants lengthen the finger; square radiants look bold and modern.
Diamond Domain sets radiants with IGI-certified lab grown diamonds in F–G color and VS1–VS2 clarity, selected for even faceting and bright light return. Settings are available in 10K, 14K and 18K gold, platinum, and custom 22K or 24K gold.
Lab grown diamonds are real diamonds with the same hardness and fire as mined stones, and they are priced well below them at the same grade. Radiants are also priced below rounds per carat, which makes them one of the most efficient ways to buy size and sparkle together.
Every radiant ring includes free engraving, a lifetime warranty, free insured worldwide shipping, free US return shipping and 30-day returns.
Frequently asked questions
What is the difference between a radiant cut and an emerald cut?
Both are rectangular with cut corners, but a radiant is cut with brilliant-style facets that produce intense sparkle, while an emerald cut has long step facets that produce broad flashes. A radiant hides inclusions and color better; an emerald cut has a calmer, more open look.
How much does a radiant cut lab grown diamond engagement ring cost?
Radiant cut lab grown diamond engagement rings at Diamond Domain start at $1,049. Radiants are priced below round brilliants at the same carat weight because they retain more of the rough crystal. A lab grown radiant is priced far below a mined radiant of the same IGI grade.
Are radiant cut diamonds durable?
Yes. The trimmed corners of a radiant remove the sharp points that make princess cuts vulnerable to chipping, and diamond scores 10 on the Mohs hardness scale regardless of origin. Every radiant ring from Diamond Domain is covered by a lifetime warranty.
Are radiant lab grown diamonds certified?
Yes. Every radiant center stone is a lab grown diamond certified by IGI, with the report number laser-inscribed on the girdle. Our standard grade is F–G color and VS1–VS2 clarity, and we select stones with even, well-aligned faceting.
Can a radiant engagement ring be returned or exchanged?
Yes. You have 30 days from delivery to return or exchange the ring, and return shipping inside the US is free. If you would like help confirming your size or choosing between a square and elongated radiant, contact us before ordering.
