1 Carat Oval Diamonds
An oval spreads its weight along the finger, so a one carat oval looks larger than a one carat round — typically around ten percent more visible surface, and the elongation lengthens the hand as well. For anyone who wants the presence of a bigger stone without the price of a bigger stone, this is the most efficient page on the site.
Decide the ratio before you compare. Between 1.30 and 1.40 an oval looks full and classic; from 1.45 upward it reads distinctly slender. Both are correct, but they are different rings, and the difference is obvious side by side while being nearly invisible in a single photograph.
Then check the bow-tie — the dark band across the centre that appears when the pavilion is cut too deep or too shallow. Every oval has one; on a well-cut stone it is faint and moves as the diamond moves. The 360° view on each product page shows it far better than any still image, and at one carat it is the single thing most worth your attention.
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.
