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 princess-cut lab-grown diamond raised on a split-shank band lined with diamonds. The square centre stone and divided shoulders give this a sharp, modern engagement look.

A princess-cut centre sits where the band splits into two rows, each tracking around the finger. The twin rows add sparkle and width while keeping the focus on the clean lines of the centre stone.

  • Stone type: Lab-grown diamond
  • Centre stone: Princess cut, approx. 7.0mm (≈ 1.61ct)
  • Stone count: 35 diamonds
  • Total diamond weight: Approx. 2.46ct
  • 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
