Round Diamond Ring

This round diamond ring is designed to feel clean, modern, and intentional. Set in a smooth bezel of solid gold, the diamond is framed with precision, creating a look that feels both refined and quietly bold.

Each Round Diamond Ring is individually created by our London atelier.

Round Diamond Ring with Bezel Setting

This round diamond ring takes one of the most classic diamond shapes and gives it a more modern, design-led finish. The bezel setting surrounds the diamond completely, creating a smooth outline that feels clean and considered.

Rather than relying on traditional prongs, the design focuses on simplicity and structure, allowing the diamond to feel more integrated into the ring.

Round Diamond Engagement Ring or Everyday Ring

This round diamond ring works effortlessly as both an engagement ring and a standalone piece. The round cut is known for its balance and light performance, while the bezel setting gives it a more contemporary, wearable edge.

It’s a strong option for those looking for something timeless but less traditional in its execution.

Lab Diamond Round Ring: Size Options

This round diamond ring is available in a range of lab-grown diamond sizes, allowing you to choose the level of presence that suits your style.

Available sizes: 0.75ct to 4ct
Diamond type: lab-grown diamond
Cut: round brilliant

Each stone is selected for strong brilliance and balance, ensuring it performs well in everyday light.

Bezel Set Round Diamond Ring Design

The bezel setting fully surrounds the diamond, offering protection while creating a smooth, uninterrupted silhouette. This makes the ring particularly suited to daily wear, without compromising on impact.

The polished gold edge enhances the diamond’s shape while keeping the overall look minimal and refined.

How to Style a Round Diamond Ring

This round diamond ring is versatile and easy to style.

Wear alone for a clean, minimal look
Pair with a simple band for a modern bridal set
Stack with fine rings for a layered, contemporary feel

Its simplicity allows it to work across different styles without feeling restrictive.

Why This Round Diamond Ring Stands Out

Bezel-set round diamond for a modern finish
Available from 0.75ct to 4ct lab-grown diamonds
Clean, sculptural design with strong presence
Suitable for engagement or everyday wear
Solid 14k or 18k gold construction
A refined alternative to traditional prong-set rings
