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.

Good design can create a rhythm you feel before you count it. Mabel sets two stone sizes across a half eternity band, giving the gold a measured beat that is clean, calm and quietly satisfying. It brings detail to daily wear without depending on a raised centre.

Eleven 1.60mm round lab-grown diamonds are balanced by ten at 1.00mm, making 21 stones and 0.24ct in total. Each sits in a collet setting within the band, so the metal shapes the spaces between them. That contrast of larger and smaller circles is what makes Mabel distinctive, ordered at first glance and more interesting the closer you look.

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

Mabel makes rhythm precious

Mabel offers the meaning of a half eternity ring with two stone sizes, 21 round lab-grown diamonds in all. The collet settings make polished gold part of the composition, while every stone is D to F colour and VS1 clarity or better. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. It is also available separately in 925 sterling silver.

Wearing Mabel

Mabel's low, flush-set stones suit frequent wear and pair easily with plain rings. Place it beside a simple band to emphasise the two stone sizes, or wear it alone for a lighter look. White gold softens the contrast, while yellow or rose gold makes each collet more visible.
