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.
A full carat makes its own introduction. Thea presents that weight in cool silver, giving someone who prefers white metal a substantial solitaire without extra stones or decoration. It is assured, feminine and centred entirely on the oval.
The single lab-grown diamond measures 7.50 x 5.70mm and weighs approximately 1.00ct. A collet setting follows the stone, while the complete pendant measures approximately 13.2 x 7.5mm including the bail. Its softly rounded sides and longer profile give the design a recognisable silhouette from a distance, yet every part remains devoted to one stone.
Prefer gold? Thea is also made in solid 14kt and 18kt gold — see the gold version.
Thea delivers the significance of a 1.00ct lab-grown diamond in a clean silver solitaire. Its 7.50 x 5.70mm oval creates a generous face, while the finished pendant measures approximately 13.2 x 7.5mm including the bail. It is made in 925 sterling silver. The stone is D to F colour and VS1 clarity or better, placing quality beside the full-carat scale.
Sold as a pendant on its own. Add a matching chain with your order — a fine 18-inch cable chain in solid 925 sterling silver.
Every piece is crafted to order in your chosen metal. Our usual timeline is around four weeks from order to dispatch. More complex pieces may take slightly longer. We confirm the expected timeframe in writing before production begins.
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.
Thea suits a dark knit, a crisp white shirt or a bare neckline, anywhere it can take the central position. Smaller silver earrings keep attention on the 1.00ct oval, while a shorter unadorned chain can add a second line above. The matching fine 18-inch silver cable chain is optional.
Does Thea contain a full carat?
Yes. Thea holds one oval lab-grown diamond weighing approximately 1.00ct. It measures 7.50 x 5.70mm, and the complete pendant is approximately 13.2 x 7.5mm including the bail.
Does Thea have a halo or side stones?
No. Thea is a true solitaire, with one 7.50 x 5.70mm oval lab-grown diamond and no halo or accent stones. It is held in a collet setting.
What comes with Thea after it is made?
Thea is made to order in around four weeks and includes a 12-month guarantee plus free tracked and signed-for UK delivery. It is sold as a pendant, with a matching fine 18-inch silver cable chain available separately.
