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 continuous line of lab-grown marquise diamonds set all the way around, this is a piece built for impact. Each stone is angled against the next so the row reads as one unbroken ribbon of light around the neck.

One hundred and twenty-four marquise-cut lab-grown diamonds run the full length of the necklace, each pointed stone tilted in the same direction to form a fluid, feather-like line. A secure box clasp keeps the row continuous and sits flush with the design.

  • Total diamond weight: approximately 18.60ct
  • Diamonds: 124 marquise-cut lab-grown diamonds
  • Stone size: 5.50 x 3.00mm each
  • Station size: approximately 3.2mm along the chain
  • Closure: box clasp
  • Metal options: 14kt or 18kt White, Yellow or Rose Gold

Chain

Supplied as a complete necklace. Choose 16, 18 or 20 inches above — 18 inches is our standard and the price is the same whichever you pick.
