Lab-grown diamond jewellery: how to choose
What a lab-grown diamond is
A lab-grown diamond is a diamond, grown in a laboratory instead of mined from the ground. It has the same carbon crystal structure, the same hardness and the same fire as a mined diamond, which is why it takes specialist equipment, not the naked eye, to tell the two apart. What changes is what your budget can do: a bigger stone, a finer design or a more generous piece of gold.
Start with the piece
Proposing? Begin with our engagement rings, from classic solitaires to halos and trilogy rings. For everyday sparkle, browse earrings and lab-grown diamond studs, necklaces and pendants, or a tennis bracelet. Buying for someone else? Our gift edit gathers earrings and pendants that need no ring size.
Choose your metal
Our gold is solid 14kt or 18kt, in white, yellow or rose, and never 9ct. 14kt gold is 58.5% pure gold and 18kt is 75%, against 37.5% in the 9ct that fills most high-street windows; our 14ct vs 9ct guide explains why that matters. For lighter budgets and everyday layering, the Silver & Lab-Grown Diamond edit sets lab-grown diamonds in 925 sterling silver.
Quality you can check
Every piece with a centre lab-grown diamond of 1.00ct or more comes with an individual IGI grading report as standard. Gold pieces are hallmarked at a UK assay office where the law requires it, so the purity of your gold is independently confirmed before it reaches you.
Made to order, delivered free
Nothing we sell sits in a drawer waiting. Each piece is made once you order it: around four weeks, including UK hallmarking where required. UK delivery is free, tracked and signed for, in a branded presentation box.
Your questions
Is a lab-grown diamond a diamond? Yes. It is made of the same carbon crystal as a mined diamond, with the same hardness and sparkle; only its origin is different.
Will lab-grown diamond jewellery last? Yes. A lab-grown diamond is just as hard as a mined one, and our gold is solid, never plated, so it is made to be worn every day.
Can you make something that is not shown here? Yes. Tell us about it on our custom jewellery page and we will design it with you.
