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.
Una does not point to a single centre. It spreads the attention across a wide, domed band, using rows of different stone sizes to build depth and movement over the whole surface. The effect is generous and self-contained, a ring designed to feel complete the moment it goes on.
Its fifty-two round lab-grown diamonds graduate through four sizes: eighteen at 2.50mm, four at 2.20mm, fourteen at 1.70mm and sixteen at 1.60mm. They sit in a U cut, multi-row arrangement across the curved band. That changing scale creates rhythm across the whole surface.
Una gives you nearly two carats of lab-grown diamonds across one substantial, centre-free design. The graduated sizes make its wide domed surface feel considered from edge to edge, while the rows sit together in a U cut arrangement. Every lab-grown diamond is D to F colour and VS1 clarity or better. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel.
This ring is made to order in your size. Choose your UK ring size when you order — there is no extra charge for any size. 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. Standard UK sizes are available — if you need guidance, contact us before placing your order.
Every piece is crafted to your chosen metal and 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.
Wear Una alone when you want its graduated rows to read as one complete design. It can also sit alongside other rings, where the domed profile and changing stone sizes create contrast with a plain band. White Gold keeps the surface pale throughout, while Yellow or Rose Gold lets the metal show as a warmer part of the composition.
Are all of Una's lab-grown diamonds the same size?
No. Una uses four sizes to create its graduated pattern: 18 × 2.50mm, 4 × 2.20mm, 14 × 1.70mm and 16 × 1.60mm. Together they form fifty-two round lab-grown diamonds.
How are Una's stones set across the band?
The round lab-grown diamonds are arranged in multiple U cut rows across a wide, domed band. The design has no single centre stone, so the changing stone sizes shape the full surface.
What is Una's total lab-grown diamond weight?
The total is approximately 1.91ct. Una is made with fifty-two round lab-grown diamonds in four graduating sizes.
