Lab-grown diamond quality

D–F colour  ·  VS1 clarity or better

Every lab-grown diamond is D–F colour and VS1 clarity or better. Round brilliant lab-grown diamonds can receive a formal cut grade; fancy shapes are assessed through their proportions, polish, symmetry and overall make. Any piece whose centre stone, on its own, weighs 1.00ct or more includes an individual IGI grading report as standard. Total carat weight does not count towards this.

Willow refuses to follow a straight line. Its band curves into an open wave around a round lab-grown diamond, turning a familiar solitaire into something fluid, expressive and full of movement.

The swirl draws away from the 6.50mm centre, leaving open space around the stone and creating the impression that it floats within the curve. This sculptural shank is the defining part of Willow, softening the geometry of the approximately 1.00ct round centre with a continuous, flowing gesture. It is made for someone who sees their story as movement, not convention, and wants the ring to carry that feeling.

Also in sterling silver. Willow is available in 925 sterling silver — see the silver version.

Willow moves differently

Willow has a sculptural, fluid profile, using an open swirl to cradle the centre with lightness and movement. Its 6.50mm round lab-grown diamond weighs approximately 1.00ct and includes an independent IGI grading report. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. White, Yellow and Rose Gold are available, plus a separate 925 sterling silver version.

Wearing Willow

The open wave gives Willow an airy shape and keeps the round centre visually distinct from the band. It has enough movement to wear confidently on its own, where the full curve remains visible. Worn alone, the full curve of the swirl stays in view.

Questions about Willow

What creates Willow's floating appearance?
The open swirl shank curves away in a fluid wave around the centre lab-grown diamond. That open space separates the stone visually from the band, creating the light, floating effect that defines Willow.

What are Willow's centre stone details?
Willow is set with one 6.50mm round lab-grown diamond weighing approximately 1.00ct. It is D to F colour and VS1 clarity or better, with an independent IGI grading report included.

Can I choose Willow in Rose Gold?
Yes. Willow is available in 14kt or 18kt Rose Gold, as well as White or Yellow Gold. It is made to order in your chosen UK ring size at no extra charge.
