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.
Louisa lets the oval breathe. Rather than closing it inside a halo, the design places a sequence of round lab-grown diamonds along the shoulders, leaving the centre's outline open and clear. The result feels bright, direct and beautifully balanced from side to side.
Its 7.40 × 5.40mm oval lab-grown diamond weighs 1.01ct. Twelve 2.20mm round lab-grown diamonds sit along the shoulders, creating a measured route from the band to the centre. Thirteen lab-grown diamonds bring the total to 1.55ct, with every accent large enough to hold its own place in the composition.
Louisa is for the buyer who loves an oval centre but prefers defined shoulders to a surrounding halo. Twelve 2.20mm round lab-grown diamonds create a clear, balanced approach to the 1.01ct oval lab-grown diamond. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. Each option is available in white, yellow or rose gold.

The open outline around the oval keeps Louisa visually clean, while the substantial round lab-grown diamonds add detail across the shoulders. It wears confidently on its own and can also sit beside a simple band, letting the oval remain the highest point of attention.
