IGI Certified Diamonds
The International Gemological Institute grades more diamonds than any other laboratory in the world, and it grades the overwhelming majority of lab-grown stones. If you are shopping grown diamonds anywhere, you are almost certainly reading IGI reports.
That concentration is genuinely useful. The single hardest thing about comparing diamonds across sellers is that laboratories differ in strictness, so two stones with the same letters are not always the same stone. Within IGI-graded inventory that problem largely disappears: the reports are internally consistent, which means a VS1 here is a VS1 there, and the comparison you make on screen is the comparison you would make with both stones in front of you.
An IGI report carries the full picture — cut, colour, clarity, carat, measurements, proportions, fluorescence, and for grown stones the growth method — along with a plotted clarity diagram. Every report number is printed on the product page and can be checked against IGI's own database before you spend anything.
We list IGI alongside GIA rather than instead of it, and each stone states its laboratory plainly. Both come with a 360° video, which is still the only way to see a bow-tie or a dull crown.
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.
