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.
Meaning does not need to be loud. Cora places an open heart softly to one side of the finger, turning a familiar symbol into something lighter, finer and more personal. It feels romantic, but the asymmetry gives it character rather than sweetness.
A slim gold line draws the heart while 10 round lab-grown diamonds follow one side of its shape. Each stone measures 1.20mm, bringing approximately 0.08ct of light to a design that deliberately leaves space open. That balance between polished gold and stones is what makes Cora recognisably its own.
Also in sterling silver. Cora is available in 925 sterling silver — see the silver version.
Cora carries its meaning in the shape itself, making it a thoughtful choice for love, remembrance or simply something personal. The 10 round lab-grown diamonds light one side of the open heart without overwhelming its fine gold outline. Every stone 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.
Cora is designed for everyday wear, with the open heart giving even a simple outfit a personal detail. Pair it with fine earrings or a pendant in the same gold colour, or let its off-centre shape bring a different line to a small ring stack.
Where are Cora's lab-grown diamonds set?
Cora has 10 round lab-grown diamonds set along one side of its open heart. Each measures 1.20mm, so the stones trace the shape while leaving the other side as a clean line of gold.
What is the total lab-grown diamond weight?
The 10 stones have a total lab-grown diamond weight of approximately 0.08ct. Every lab-grown diamond used by The Lab Jewellers is D to F colour and VS1 clarity or better.
Can I order Cora in my UK ring size?
