Buying guide

What makes a radiant cut different

A radiant cut has the straight sides of an emerald cut and the facet pattern of a round brilliant, so it combines a clean outline with strong sparkle. Its corners are trimmed, which makes it less likely to chip than a princess cut. Radiants range from nearly square to long rectangles, and a longer stone looks larger on the hand.

Choosing a setting

A solitaire with four prongs shows the full outline. Halo and hidden halo designs add lab-grown diamond accents around or under the center. Side stone and three stone settings, including some with marquise side stones, build width along the band. Bezel settings wrap the edge for a sleek, protective look, and vintage, floral and milgrain designs suit an older style. Split shank and twisted bands add detail at the shoulders.

Metal and price

Yellow gold is offered on the most designs in this collection and warms the center; white gold makes it look crisp and bright; rose gold adds a soft blush. Settings start from about $400, and most are between about $1,000 and $1,300. That price covers the setting; the center is priced when you choose it.

Made to order

Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.

Radiant Cut Engagement Rings FAQs

What is a radiant cut diamond?

A radiant cut diamond is a rectangular or square stone with trimmed corners and a brilliant facet pattern. It blends the outline of an emerald cut with the sparkle of a round, so it looks both structured and lively. In a ring, the trimmed corners make it easier to set securely than a sharp-cornered princess cut.

Is radiant cut good for an engagement ring?

Yes. A radiant cut sparkles strongly, hides small inclusions well thanks to its many facets, and its trimmed corners resist chipping. An elongated radiant also looks larger than its weight. The main trade-off is that some radiants carry extra weight in the base, so compare face-up size as well as carat weight when you choose the center.

What are the disadvantages of a radiant cut diamond?

The main disadvantages are hidden weight and uneven proportions. Some radiants are cut deep, so they look smaller face-up than their carat weight suggests. Shapes vary widely from square to long, and a poorly cut stone can show a dark bow-tie shadow. A well-cut radiant never looks cheap; its sparkle is simply bolder and more angular than a round's.

Are radiant cuts more expensive?

Usually not. A radiant cut often costs less per carat than a round brilliant of the same weight and quality, because cutting it keeps more of the rough crystal. Prices are similar to other fancy shapes like cushion and oval. On this page, settings start from about $400, and the center is priced separately when you choose it.

Radiant vs cushion cut: which is better?

Neither is better; they suit different tastes. A radiant has straight sides and trimmed corners for a crisp, modern outline, and its sparkle is bright and sharp. A cushion has rounded corners and softer, larger flashes of light that read more vintage. Both hide inclusions well. If you like clean lines, choose radiant; for a softer look, choose cushion.
