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.
Robyn looks drawn before it looks decorated. Clean lines of gold cross at the top of the finger, creating an architectural shape that gives every round lab-grown diamond a clear route to follow. It suits the person who notices structure, proportion and the pleasure of a piece that feels designed from the ground up.
Thirty prong-set stones map the crossover in six exact sizes, beginning at 0.90mm and reaching 1.40mm. Nineteen 1.20mm round lab-grown diamonds create the central rhythm, while the remaining sizes resolve the changing lines. There is no conventional centre stone. The meeting of the gold paths is Robyn's focal point.
Also in sterling silver. Robyn is available in 925 sterling silver — see the silver version.
Robyn makes the architecture of the ring the reason to choose it. Thirty round lab-grown diamonds total 0.22ct and track the clean crossover, with six stone sizes allowing the setting to follow each change in the gold. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. White, Yellow and Rose Gold each give its geometric lines a different visual temperature.
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.
Give Robyn space on the finger when you want its crossed lines to read at once. In a stack, place it beside a plain band that supports the geometry without competing with it. Its architectural shape also pairs well with simple earrings or a clean pendant in the same chosen gold colour.
Does Robyn have a centre stone?
Robyn is built around crossed lines rather than one conventional centre stone. Thirty round lab-grown diamonds follow the geometric gold paths, making the point where those paths meet the visual centre of the complete design.
What stone sizes are used across Robyn?
Robyn uses six sizes of round lab-grown diamonds, from 0.90mm to 1.40mm. Nineteen stones measure 1.20mm, while the other sizes help the prong-set arrangement follow the changing lines of the crossover.
What quality are the lab-grown diamonds in Robyn?
Every lab-grown diamond set by The Lab Jewellers is D to F colour and VS1 clarity or better. Robyn contains thirty round lab-grown diamonds with a total weight of approximately 0.22ct.
