1.5 Carat Oval Diamonds
A 1.50 ct oval measures roughly 9 by 6.5 mm. Set east-west or north-south it covers noticeably more finger than a round of the same weight, which is why this band has become the default choice for buyers who considered a two carat round and preferred the proportions.
At this size the ratio decision carries more weight, literally. A 1.75 ratio oval at 1.50 ct looks dramatically longer than a 1.30 ratio oval of identical weight, and the slender version tends to photograph better while the fuller version tends to look richer in person. Choose deliberately rather than by price alone.
Colour becomes worth a second look here. Elongated shapes concentrate any warmth at the two ends, so a colour I stone that looks perfectly white as a round can show a faint tint at the tips as an oval. G or H is the comfortable range at this size.
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.
