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.
Silver takes an unexpected turn. Robyn crosses clean lines over the finger, giving a familiar ring form a sharper, more graphic character. It feels current without relying on one oversized focal stone, and brings interest from the direction of the band itself.
Across those intersecting paths sit 30 prong-set round lab-grown diamonds. Six measured sizes run from 0.90mm through to 1.40mm, including 19 stones at 1.20mm. That careful mix lets the setting continue through every change of angle. The 0.22ct total belongs to the complete geometric composition, making Robyn as much about line and motion as it is about light.
Prefer gold? Robyn is also made in solid 14kt and 18kt gold — see the gold version.
Robyn is a strong choice for someone drawn to clean design but unwilling to settle for a plain band. Its crossing form carries 30 round lab-grown diamonds, using six sizes to maintain the geometry across the finger. The ring is made in 925 sterling silver, and all its lab-grown diamonds are D to F colour and VS1 clarity or better. It is made specifically for your chosen UK ring size.
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. More complex pieces may take slightly longer. We confirm the expected timeframe in writing before production begins.
Robyn works especially well as the main shape on the hand, with its crossed top providing all the detail needed for daily wear. Pair it with unfussy silver earrings or a simple silver necklace. If adding another ring, choose a plain fine band and leave the intersection easy to see.
Sterling silver naturally darkens a little over time. It is normal, and a silver polishing cloth brings it straight back. Please don't use silver dip solutions on lab-grown diamond-set pieces, as the chemicals can damage the settings. Store it on its own in the pouch or box provided, and take it off before swimming, exercising or sleeping. See our Materials & Care guide for full instructions.
Are all the stones in Robyn the same size?
No. Robyn combines six sizes of round lab-grown diamonds: 0.90mm, 1.00mm, 1.10mm, 1.20mm, 1.30mm and 1.40mm. Nineteen of the 30 are 1.20mm, with the other five sizes making up the remaining 11.
How much lab-grown diamond weight does Robyn have?
The 30 round lab-grown diamonds provide 0.22ct in total. That weight is shared along the intersecting silver lines that make up the geometric top of the ring.
How colourless and clear are Robyn's stones?
Every lab-grown diamond in Robyn is D to F colour and VS1 clarity or better. The ring itself is made in 925 sterling silver and produced to the UK ring size you select when ordering.
