Lab-Grown Diamonds
A lab-grown diamond is a diamond. Not a simulant, not a substitute: carbon crystallised in the same cubic lattice, with the same hardness, the same refractive index and the same optical behaviour as a stone that formed underground. A gemmologist cannot tell the difference by looking; identifying one requires equipment that reads the growth pattern, which is why every stone we list carries a report from a laboratory that has done exactly that.
What differs is supply. Mined rough is finite and unevenly distributed across sizes and qualities, and its pricing reflects that scarcity. Grown material is produced to order, so the price curve is much flatter — the premium for going up a carat, or up two colour grades, is a fraction of what it is in mined stones. In practice that means most buyers here stop compromising: they take the size they wanted and the clarity they wanted, rather than trading one against the other.
The trade-off is resale. Grown diamonds do not hold value the way mined stones have, and anyone telling you otherwise is selling something. If the stone is to be worn rather than banked, that matters less than the two extra carats.

Questions people ask before buying
Are these diamonds certified?
Yes. Every stone is graded by GIA, IGI or HRD, and the report number is shown on the stone's page so you can verify it directly with the laboratory. A stone certified by any other laboratory, or ungraded, cannot be bought here at all.
Does the price include a setting?
No. Loose diamonds and ring settings are priced separately, so you can pair any stone with any setting in a compatible shape. The ring builder shows the two together and the combined total before you order.
What should I prioritise when choosing?
Cut first — it is the only grade you can see across a room. Then clarity down to eye-clean, usually VS2 or SI1. Then colour: G or H reads white in platinum, I or J in yellow gold. Then buy just under a landmark weight, because 0.95 ct looks like 1.00 ct and costs less. The guide to the 4Cs explains the trade-offs in full.
How much is shipping?
Nothing. Every order ships free and fully insured, anywhere in the world, at any order value. Import duties and taxes outside the United States are the recipient's responsibility.
Can I return it?
Yes, within 30 days, unworn and in its original packaging with the certificate. The return leg is arranged and paid by you, and must be insured and tracked.
Is there a warranty?
A lifetime warranty against any manufacturing defect, for as long as you own the piece. Full detail on the FAQ page.
