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.

Three moments, held in one clear line. Lena gives the familiar trilogy a calm, grounded character, placing three matched round lab-grown diamonds directly into the band. It can mark what has been, what is here now and what comes next, or simply appeal because its symmetry feels complete.

Nothing interrupts the order of the design. Each stone measures 2.50mm, so no single point takes over from the others. The U-cut setting keeps the trio integrated with the gold band, creating a simple, low arrangement that sits smoothly on the finger and makes sense beyond one special day.

Also in sterling silver. Lena is available in 925 sterling silver — see the silver version.

Three equal reasons for Lena

Lena is for someone who wants meaning and balance in equal measure. Its three matched 2.50mm round lab-grown diamonds total 0.19ct, forming a trilogy with no centre stone made more important than the others. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. White, Yellow and Rose Gold give you three different ways to make its simplicity your own.

  • Stone type: Lab-grown diamond
  • Stone shape: Round
  • Stones: 3 × 2.50mm
  • Stone count: 3 lab-grown diamonds
  • Total lab-grown diamond weight: approximately 0.19ct
  • Metal options: 14kt or 18kt White, Yellow or Rose Gold

Made to 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.

Wearing Lena

The low, smooth arrangement makes Lena an easy choice for regular wear. Its straight line of matched stones looks complete by itself, while the simple gold band also pairs neatly with a plain ring. Keep the trilogy central when you want its three equal points to carry the meaning.

Questions about Lena

Are all three stones in Lena the same size?
Yes. Lena is set with three matched 2.50mm round lab-grown diamonds. Their equal size gives the trilogy its calm symmetry and keeps the meaning open, without placing greater emphasis on the centre stone.

What setting does Lena use?
The three round lab-grown diamonds sit in a U-cut setting within the gold band. This creates the simple, low arrangement described in the design and allows the matched line of stones to feel integrated rather than raised apart.

How long will my made-to-order Lena ring take?
Lena is made to order in around four weeks and in your chosen UK ring size at no extra charge. Once ready, it comes with free tracked and signed-for UK delivery and a 12-month guarantee.
