Lab Diamond Radiant Cut Engagement Rings

About This Shape

Developed in the 1970s, this was the first square shape to feature a complete brilliant facet pattern on both crown and pavilion. The radiant cut diamond offers exceptional radiance compared to step alternatives. Cropped corners add durability and create a distinctive silhouette that sits beautifully in four prong or bezel mounts. Whether square or slightly rectangular, this shape appeals to modern tastes.

Radiant Solitaire Styles

A radiant solitaire engagement ring places full focus on the centre stone, letting its unique facet pattern catch the light from every angle. This timeless approach works beautifully in white gold or platinum where the metal enhances brightness. For those who prefer warmth, yellow gold creates a stunning contrast that highlights the radiant engagement ring's fire. Our solitaire options range from delicate bands to more substantial shoulders.

Lab Grown Options

Our lab grown pieces offer the same optical properties as mined stones at a fraction of the cost. Each lab grown diamond comes with independent certification confirming colour, clarity and carat weight. Choosing lab grown allows you to select a larger stone or higher grade within your budget. This shape in lab grown form represents exceptional value without compromise on beauty or durability.

Metal Choices

White gold remains the most popular choice for this shape, offering a contemporary look that maximises perceived whiteness. Platinum provides ultimate durability for those who prioritise longevity. Yellow gold and rose gold create warmer aesthetics that suit vintage inspired looks. All our pieces are crafted in 18 carat gold or 950 platinum, hallmarked in the UK to guarantee quality.

FAQs

Is this shape good for engagement rings?

Yes, the radiant is excellent. It combines brilliant sparkle with a modern rectangular silhouette. The cropped corners make it more durable than sharp cornered alternatives, and the 70 facets create exceptional fire and light return.

What are the cons of this shape?

The main consideration is that this shape can show colour more readily than round brilliants. We recommend G colour or above in white gold mounts. It can also appear slightly smaller than elongated shapes of the same carat weight.

Radiant vs emerald - which is better?

It depends on your preference. The radiant offers more sparkle due to brilliant faceting, while emerald has a sophisticated hall of mirrors effect. The radiant also hides inclusions better, allowing you to choose a lower clarity grade.
