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 refined three-stone ring built around an elongated radiant-cut lab-grown diamond, framed by a pair of step-cut emerald side stones. The trio sits low and balanced across the finger, giving the centre stone its full presence while keeping the overall profile clean and wearable.

The radiant centre is flanked by two emerald-cut diamonds that echo its proportions. The shoulders run into a smooth, gently tapered band that meets the side stones flush, so the line of the ring stays uninterrupted from every angle.

  • Stone type: Lab-grown diamond
  • Stone shapes: Radiant centre with emerald-cut sides
  • Centre stone size: 7.50 x 5.50mm (approx. 1.5ct)
  • Stone count: 3 diamonds
  • Total diamond weight: approximately 1.70ct
  • Certificate: includes an independent IGI grading report for the centre stone, at no extra cost.
  • Metal options: 14kt or 18kt White, Yellow or Rose Gold
