Natural Diamonds

Every natural diamond in this collection crystallised somewhere between one and three billion years ago, roughly 150 kilometres down, and reached the surface in a volcanic eruption that happened long before anything walked on land. That history is the entire reason mined stones are priced the way they are, and it is worth being clear about: you are paying for scarcity and provenance, not for any optical property a grown stone lacks.

Because supply is finite and uneven, the pricing behaves in ways worth exploiting. Price steps at the round weights, not at the millimetre, so a 0.92ct and a 1.00ct look the same on the hand and do not cost the same. Faint fluorescence is discounted well beyond any visible effect. Certain shapes — marquise, pear, emerald — are cut from awkward rough and priced by how much of it survives, which is why a 1.50ct emerald cut can undercut a 1.50ct round.

What we do not discount is cut. A poorly proportioned mined stone is still a poorly proportioned stone, however old it is.

Every diamond here carries its original GIA, IGI or HRD report, and every one can be viewed in 360° before you commit to it.

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.
