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.

Sloane leaves a little room in the story. The open band breaks the expected circle, giving the ring a light, considered shape that stops short of closing. It is a modern pause, drawn across the finger in graduating stones.

Twenty-four round brilliant lab-grown diamonds build the form from both ends. The stones begin at 0.80mm and rise in steps to 1.50mm, swelling towards the front before tapering away again. Every stone is prong set, so the graduation remains clear. That open shape and measured change in scale are what make Sloane unmistakably itself.

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

The beauty of open space

Sloane brings shape as well as light, using an open band and 24 graduating round brilliant lab-grown diamonds to create a light, modern shape. The 0.23ct total is distributed from 0.80mm to 1.50mm, creating a deliberate rise towards the front. 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, alongside a 925 sterling silver version.

If you are unsure of your size, our ring sizer makes it easy at home — and your £5 comes straight back to you as a gift card.

Made to Order

Every piece is crafted to your chosen metal and ring size. Our usual timeline is around four weeks from order to dispatch, which includes UK hallmarking where required. More complex pieces may take slightly longer. We confirm the expected timeframe in writing before production begins.

Wearing Sloane

Sloane sits comfortably beside other stacking rings without crowding them. Keep the open shape clear by pairing it with a simple narrow band, or wear it alone so the graduated stones define the look. Choose the same metal as your regular rings for an easy, coherent stack.

Questions about Sloane

How do the stones graduate across Sloane?
The 24 round brilliant lab-grown diamonds range from 0.80mm to 1.50mm. They increase towards the front and taper away at the ends, creating the open band's balanced shape.

What setting does Sloane use?
Every round brilliant lab-grown diamond is prong set. The setting keeps the individual sizes readable as the 0.23ct total graduation moves towards the front of the ring.

Can Sloane be made to my ring size?
Yes. Select your UK ring size when you order at no extra charge. If you need help measuring, the ring sizer costs £5 and the £5 is returned as a gift card.
