Radiant Diamonds

Radiant Cut Diamond Engagement Rings

The radiant cut diamond is one of the most spectacular shapes in fine jewellery — bold, brilliant, and unmistakably modern, yet with a timeless elegance that never dates. With 70 meticulously cut facets, the radiant diamond delivers exceptional light performance in every direction, combining the fire of a round brilliant with the architectural lines of an emerald cut to create something entirely its own.

At Alan Bick, our radiant cut diamond engagement rings are made to order in our Hatton Garden, London workshops — each one handcrafted to your exact specifications, with your choice of natural or lab-grown diamond, setting, and metal.

What makes the radiant cut special?

The radiant cut was developed specifically to bring maximum brilliance to a rectangular diamond shape. Its 70-facet brilliant cut structure — unlike the step-cut faceting of an emerald cut — means the stone sparkles intensely in all lighting conditions, hiding imperfections effortlessly and delivering a depth of brilliance that makes it one of the most impressive diamond shapes available.

The radiant cut’s trimmed corners give it a refined, contemporary edge while also making it more durable than sharper-cornered cuts like the princess. It is available in both square and elongated rectangular proportions, allowing you to tailor the look to your preference — chunkier and bolder, or slender and elongated.

Radiant cut diamonds also tend to offer excellent value compared to round brilliant diamonds of the same carat weight, making them a compelling choice for those who want maximum impact within their budget.

Our radiant cut diamond ring collection

Every radiant cut ring in our collection is available with a choice of natural or lab-grown centre diamond, from 0.5ct to 3.0ct, in your preferred colour (D–H) and clarity (FL–SI2), with optional GIA or IGI certification.

Why You Should Get a Radiant Engagement Ring

What do you get when you combine the linear structure of rectangular shaped diamonds with the brilliance of round diamonds? The result is a beautiful and unique diamond shape called Radiant. The radiant cut has 70 intricate facets, maximising its ability to reflect light which creates a luxurious, multidimensional sparkle, making the radiant cut one of the most brilliant fancy-cut diamonds.

Exceptional Sparkle

The radiant cut has a 70-facet structure, which makes it one of the most brilliant diamond shapes, as it can reflect light beautifully on all of its facets, creating an unmatched sparkle.

Versatility in Shape

The radiant-shaped diamond can appear to be more rectangular to give a slender and elegant look, and it can also be a squarish shape for a bolder, chunkier, and more dramatic look. Moreover, the trimmed corners and stylish lines that contour the stone make this unique cut the perfect choice for those who love something extraordinary.

Hides Imperfections

Since naturally occurring diamonds are formed over billions of years, no two diamonds are the same and that means they are prone to blemishes and imperfections. A major advantage of having so many facets is that the imperfections can be hidden and are less obvious in this cut.

Perfect for All Settings

The radiant cut looks great in all settings, and that’s because the cut itself is so stunning. You can put it in a solitaire setting, Halo, or with side stones, and it is sure to catch the eye of anyone who sees it. It looks beautiful against the traditional yellow gold band or for a more contemporary look, you can pair it with rose gold.

Unique Yet Timeless

Since the radiant cut diamond ring takes elements from the classic round diamond shape and the more modern rectangular shaped diamond, it offers a blend of unique and timeless elegance that appeals to a range of aesthetics.

Lea Radiant Cut Diamond Hidden Halo Engagement Ring

A masterpiece of elegance and craftsmanship, this radiant-cut diamond engagement ring is designed to maximise the brilliance of the centre stone and add refined details. The centre diamond is a finely polished radiant-cut diamond that is held securely in a claw setting, allowing maximum light to pass through for a sparkle unlike anything you’ve seen before.

What makes this radiant cut engagement ring truly special is the hidden halo, which is a delicate row of round brilliant diamonds that are set discreetly beneath the centre stone. These hand-selected diamonds perfectly match the quality of the main stone, adding an extra layer of shimmer that is visible from different angles, creating a subtle yet luxurious effect.

Weight

The centre diamond that comes in the setting is a 1.40ct stone; however, depending on your preference and budget, you can opt for any carat weight between 0.50ct and 3.00ct.

Colour

This setting comes in the colour F, which is nearly colourless and one of the brightest colours when it comes to diamonds, but you can also opt for a different colour depending on what you want for your buck Alan Bick offers a colour range from D-G.

Clarity

While this setting comes in VS clarity, you can opt for any clarity from FL (flawless) to VS2 (very slightly included 2).

Metal Band

The width of the ring is 2 mm, with an approximate total weight of 2.8 grams in 18ct gold and 3.8 grams in platinum. For 18ct gold (rose gold, white gold, or yellow gold), the ring will be hallmarked 750 inside the ring and 950 for platinum.
