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.
A garden held in gold. Zinnia turns the softness of a flower into something you can keep close, with forty round lab-grown diamonds gathered across its petals. It feels joyful rather than formal, romantic without waiting for an occasion.
The detail is in the way the stones grow. Six exact sizes, from 1.00mm to 1.50mm, are arranged so the floral form reads as one continuous design rather than a collection of separate points. Each round lab-grown diamond is prong set, allowing the graduated pattern to carry the eye across the whole bloom.
Also in sterling silver. Zinnia is available in 925 sterling silver — see the silver version.
Zinnia gives you the richness of an intricate floral design while keeping every detail precise. Its forty round lab-grown diamonds total 0.36ct, with graduated sizes shaping the petals and bringing rhythm to the surface. 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 the flower a distinct character.

Let Zinnia be the focus on one hand, where its floral outline can be seen clearly. It also works at the centre of a considered stack, with simpler bands giving its graduated petals room. The choice of White, Yellow or Rose Gold lets it sit easily with jewellery you already wear.
How are Zinnia's forty stones arranged?
Zinnia uses six graduated sizes of round lab-grown diamonds, from 1.00mm to 1.50mm. Their changing scale shapes the floral pattern, so the petals flow together as one continuous field rather than appearing as separate clusters.
What is the total lab-grown diamond weight?
The forty round lab-grown diamonds total approximately 0.36ct. Every lab-grown diamond set by The Lab Jewellers is D to F colour and VS1 clarity or better, giving the detailed floral arrangement a consistent quality.
Can Zinnia be made in my ring size?
Yes. Zinnia is made to order in your chosen UK ring size at no extra charge. If you are unsure, the £5 ring sizer can be used at home, and the £5 is returned as a gift card.
