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.
