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.
Cool is the word for Constance. A long emerald-cut lab-grown diamond sits in the middle with a princess-cut lab-grown diamond on each side, all set in 925 sterling silver. No scattering of smaller stones, no fuss, just three stones and the quiet elegance of step cuts.
The emerald-cut centre is a 6.00 × 4.00mm lab-grown diamond of 0.50ct. Two princess-cut lab-grown diamonds, each 3.75 × 3.75mm, add 0.66ct between them. This brings the trilogy to 1.16ct. A rectangle between two squares is the whole idea, and the proportions of the stones carry it.
Prefer gold? Constance is also made in solid 14kt and 18kt gold — see the gold version.
Constance chooses clear geometry
With 1.16ct shared between only three lab-grown diamonds, every stone in Constance is easy to see and enjoy. A 0.50ct emerald-cut centre sits between princess-cut sides weighing 0.66ct together, a trilogy engagement ring with clean, structured lines. Every stone is D to F colour and VS1 clarity or better. Constance is made in 925 sterling silver and tailored to the UK ring size you select.

Wearing Constance
Constance suits a smart day at work or an evening out. The cool 925 sterling silver goes well with the emerald and princess cuts, so all three lab-grown diamonds sit against one calm backdrop, and a silver polishing cloth keeps the finish fresh.
Caring for Sterling Silver
Sterling silver naturally darkens a little over time. It is normal, and a silver polishing cloth brings it straight back. Please don't use silver dip solutions on lab-grown diamond-set pieces, as the chemicals can damage the settings. Store it on its own in the pouch or box provided, and take it off before swimming, exercising or sleeping. See our Materials & Care guide for full instructions.
