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.
One stone. Nothing to hide behind. Sylvie is for the person who has made one clear choice and wants the ring to say it with the same confidence. A single round brilliant lab-grown diamond takes the centre, with a slim polished band that gives it nowhere to disappear.
The centre is approximately 1.50ct and 7.4mm across. A tapered head lifts it clear of the finger and lets light enter from every side. The plain band keeps the design focused and leaves room for a wedding band now, then an eternity ring later.
One confident choice does all the work. Sylvie gives you one approximately 7.4mm, 1.50ct round brilliant lab-grown diamond, with an independent IGI grading report included at no extra cost. The tapered head opens the centre to light from every side. Choose 14kt white, yellow or rose gold for the harder, more scratch-resistant gold, or 18kt in the same colours for more pure gold and a heavier feel. Every UK ring size costs the same.
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 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.
The slim polished band keeps Sylvie easy to pair without competing with its centre. Wear it beside a plain wedding band, then add an eternity ring later if you wish. The raised tapered head leaves the centre clear, while the plain band keeps the stack balanced.
