Lab-Grown Luxury: The Radiant Diamond Ring You Need

One thing everyone wants in an engagement ring? Sparkle. But not all diamonds are cut from the same cloth. One of the most jaw-dropping? The radiant cut diamond—with a name like that, it's gotta be good, right? Radiant cut diamonds often don’t get the love they deserve, mostly because they’re not as heavily marketed as rounds, ovals, or emeralds—but that’s exactly why they’re such a smart choice.

This stunning diamond shape offers the best of both worlds: the clean, modern lines of an emerald cut with the insane sparkle of a round brilliant, thanks to their extra facets. Plus, they look bigger for their carat weight and are more durable than princess cuts thanks to their beveled edges. Add lab grown radiant cut diamonds to the mix and you've got another plus side: affordability. But before you hit "add to cart" on your dream ring, let's break down everything you need to know about lab-grown radiant diamonds and the ring styles that make them shine.

The radiant cut combines emerald-edge elegance with brilliant-cut fire—aka sparkle that actually stops traffic.

Why Lab-Grown vs. Natural Diamonds?

Lab-grown diamonds are, quite literally, real diamonds. They have the same chemical composition, the same physical properties, and the same "OMG, that’s sparkly" effect as natural diamonds. The only difference? One was formed underground over millions of years, and the other was created in a high-tech lab in a matter of weeks. Lab grown diamonds and gemstones offer you a bigger, brighter stone for your budget, and they're more sustainable to boot. No mining is involved, they require less environmental resources and are an ethical choice so you can have a clean conscience.

What is a Radiant Cut Diamond?

The radiant cut diamond is the perfect mix of sparkle and structure, a brilliant hybrid between the fiery round brilliant and the sleek, sophisticated emerald cut. Designed in 1977 by Henry Grossbard, this diamond cut was created to maximize brilliance while maintaining the clean, geometric appeal of step-cut diamonds. They are unique for their dazzling 70-facet pattern that scatters light in every direction. Truly some of the best light performance you'll find in a square or rectangular shape on the market, perfect if you want classic sparkle with a modern twist.

Radiant cut diamonds come in two main shapes: square and elongated. The square radiant has a balanced, bold look, while the elongated version creates a finger-lengthening effect and is also fantastic for today's popular east-west engagement ring settings. One of the best things about a radiant cut is how well it hides inclusions and color—its faceting pattern is much more forgiving than an emerald or Asscher cut, meaning you don’t have to splurge on the absolute highest clarity grade to get a stunning, eye-clean stone. However, because radiant diamonds can vary in their exact proportions, it’s important to look at a stone’s length-to-width ratio to find the ideal shape for your style. A good rule of thumb: square radiants typically fall within a 1.00–1.05 ratio, while elongated versions can range from 1.15 up to 1.35 or more, depending on your preference.

Radiant Ring Styles to Love

So you're sold on a radiant cut stone now, right? Let's talk about the ring setting itself. Which styles look great with a radiant cut? Which fall flat? And which one is the right choice for you?

• Solitaire – A single radiant diamond on a slender band lets the stone be the star of this show. You can opt for a classic four-prong ring in yellow gold or go modern with a 14k white gold setting that shows off the brightness of the diamond's brilliance. Play with the width of the band, the number of prongs, or different ring profiles to make it your own.

• Bezel – Modern, minimalist, and super practical, a bezel setting surrounds the diamond in metal, making it great for active lifestyles. If you want a bit less metal, a half-bezel is a modern twist, which has metal on two sides of the diamond instead of all the way around. It's sleek, sophisticated, and shows off the scintillation of that radiant cut to its full advantage.

• East-West – A fresh, contemporary twist on tradition, this setting turns the diamond horizontally for a chic, unexpected look. The on-trend style can also help your diamond look larger as it spreads wider across the finger. Note that you'll want to shop for an elongated, rectangular radiant cut for this style, not a square one.

• Three Stone – Symbolizing past, present, and future, the three-stone ring setting is sentimental and offers tons of sparkle. There are a few different ways to rock this style. You can go with three radiant cut diamonds to really lean into the shape. You can go with the classic baguette side stones. Or you can mix and match diamond shapes for a totally unique take.

• Channel – Sleek and sophisticated, channel-set bands secure smaller diamonds in a smooth row with no prongs, making it a low-maintenance yet ultra-glamorous option.

• Split Shank – A stylish take on the classic solitaire, the split shank gives the ring a little extra dimension and detail. The shoulders of the ring spread out to frame your center diamond in a vintage-feeling vibe.

• Chunky – If you love a bold statement, a thick, heavy band paired with a radiant diamond creates the ultimate power ring. We love a modern lab-grown radiant cut diamond signet ring.

• Halo – A modern classic, halo rings encircle your diamond in a ring of smaller diamonds to add tons of brilliance and make your overall ring look larger. You can go with a slim, single halo or a multi-row look if you want something a bit more bold.

• Toi Et Moi – Meaning "you and me" in French, this style features two stones side by side, making it a super romantic and trendy choice. Thank Megan Fox and Ariana Grande for this one. Radiant cut diamonds make a great pairing with round, pear, and oval shapes, for instance.

Lab-Grown Fancy Yellow Radiant Diamonds

If you're looking for an engagement ring that breaks the mold, a lab-grown fancy yellow radiant diamond should do the trick. Radiant cuts are already known for their intense sparkle, but when paired with a vibrant yellow hue, they become otherworldly. The unique faceting of radiant cuts amplifies color, making fancy yellow diamonds appear even richer and more saturated. When shopping for one, aim for stones graded as “Fancy,” “Fancy Intense,” or “Fancy Vivid” to get the most eye-catching brilliance. Unlike step-cut shapes that soften color, the radiant cut enhances it, ensuring your yellow diamond glows with warmth and personality.

Fancy yellow radiant diamonds and radiant-cut sapphires bring bold energy to a timeless shape.

Radiant Sapphires: Bold, Bright, and Blue

Lab-grown radiant sapphire rings are another beautiful option, offering vibrant color, durability, and ethical sourcing all in one stunning package. Sapphires are known for their incredible hardness—second only to diamonds—making them an excellent choice for an engagement ring that can handle everyday wear. Lab-grown sapphires are chemically and optically identical to their mined counterparts but come without the ethical concerns or high price tags associated with natural stones. While deep blue remains the most iconic sapphire hue, lab-grown options open up a world of color possibilities, from striking pinks to rich yellows and even dreamy teals.
