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.

Your eye knows exactly where to go. Tara uses two fine lines of smaller stones to guide it towards a full one-carat round centre, giving a classic shape a more deliberate arrival. The shoulders do not compete with the centre. They lead to it.

A 6.50mm round lab-grown diamond anchors the ring, with twelve 1.50mm round lab-grown diamonds shared across the shoulders. Thirteen stones create a total of approximately 1.18ct. Because every stone is round, the design feels connected from band to centre, while the change in scale gives Tara its clear hierarchy.

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

Tara leads to the one

Tara gives you the clarity of a one-carat centre with smaller lab-grown diamonds drawing attention towards it. The 6.50mm centre includes an independent IGI grading report, and the complete ring carries approximately 1.18ct. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. White, Yellow and Rose Gold are offered, with a separate 925 sterling silver version available.
