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.

Winnie proves that delicacy can still have direction. Its open halo draws a light circle around the centre, then the same round forms travel into the shoulders, giving a smaller-scale ring a complete and considered shape. It is easy to live with, but never an afterthought.

A 2.80mm round lab-grown diamond sits at the centre. Eighteen 1.20mm and fifteen 1.00mm round lab-grown diamonds form the halo and shoulder detail, bringing the count to 34 and the total to 0.31ct. The two accent sizes allow the design to move smoothly between its focal point and band.

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

Winnie's lighter way to shine

Winnie offers the detail of a halo and decorated shoulders in a refined 0.31ct design. Thirty-four round lab-grown diamonds give the centre a frame and the band a sense of continuity without relying on a large principal stone. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. A separate 925 sterling silver version is also available.

Wearing Winnie

Winnie's compact centre and detailed shoulders make it comfortable as an everyday favourite, whether worn alone or beside a simple band. White gold keeps the look tonal, while yellow or rose gold gives the round lab-grown diamonds a warmer frame. Let the open halo remain visible from above.
