Diamond quality

D–F colour  ·  VS1 clarity or better

Every diamond is lab-grown, D–F colour and VS1 clarity or better. Round brilliant diamonds can receive a formal cut grade; fancy shapes are assessed through their proportions, polish, symmetry and overall make. Any piece with a centre stone of 1.00ct or more includes an independent IGI grading report or GIA quality assessment as standard.

A three-stone ring built around a cushion-cut lab-grown diamond, with a trillion-cut stone set to either side. The trio fills the finger while keeping a clean, classic outline.

A cushion centre is flanked by two trillion diamonds angled into the shoulders, giving a continuous line of stones across the top of the ring. The smooth band underneath keeps the look understated.

  • Stone type: Lab-grown diamond
  • Centre stone: Cushion cut, approx. 1.78ct
  • Side stones: Trillion cut (×2)
  • Stone count: 3 diamonds
  • Total diamond weight: Approx. 2.39ct
  • Certificate: includes an independent IGI grading report for the centre stone, at no extra cost.

This ring is made to order in your size. Choose your UK ring size above — 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.

Made to Order

Every piece is crafted to your chosen metal and ring size. Our usual production lead time is approximately two working weeks before dispatch. More complex pieces may take slightly longer. We confirm the expected timeframe in writing before production begins.

Styling

With a larger total carat weight, this trio makes a confident statement as an engagement or anniversary ring. Wear it solo to let the three stones stand out.
