Natural Oval Diamonds
An oval spreads its weight along the finger, so it reads larger than a round of identical carat — usually by around a tenth. That is the whole appeal, and it is also why an oval has to be judged on two things a certificate barely mentions.
The first is the length-to-width ratio. Between roughly 1.35 and 1.50 an oval looks elongated and elegant; below that it drifts towards a fat round, above it starts to look stretched. There is no correct number, only the one you prefer, but it is worth deciding before you look at stones rather than after.
The second is the bow-tie: the dark band across the waist that every oval has to some degree. A faint one adds contrast and life. A heavy one is a dead zone that no setting will fix. No grading report scores it, which is precisely why we put a 360° video on every stone — thirty seconds of rotation tells you more about a particular oval than the entire report does.
On mined ovals, buying at 1.40ct rather than 1.50ct is the sensible saving. The face-up difference is well under half a millimetre; the price difference is not.
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.
