Marquise Diamonds
No shape gives more visible diamond per carat than the marquise. Its two points stretch the outline in both directions, so a marquise looks substantially larger than a round of the same weight and elongates the finger while it does so.
The classic ratio runs from 1.85 to 2.10. Shorter than that and the stone looks stubby; longer and it becomes fragile at the tips. Symmetry matters more here than in any other shape — if the two points do not align on a single axis the eye catches it immediately, so read the symmetry grade on the report rather than trusting a photograph.
Like the oval and the pear, the marquise shows a bow-tie through the centre. And because the points are the thinnest part of any diamond, a setting with V-prongs covering both tips is not a style choice but protection.
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.
