Cushion Cut Diamonds
The cushion is the oldest shape still in wide use — a rounded square with soft corners, descended from the old mine cut. Two very different diamonds share the name, and the report will not tell you which one you are looking at.
A crushed-ice cushion scatters light into many small glints and hides inclusions well. A chunky or modified cushion returns fewer, larger flashes and looks closer to a round. Neither is better, but they photograph almost identically and look nothing alike in the hand, so use the 360° view before choosing.
For a square cushion aim for a ratio of 1.00 to 1.09; above 1.15 you are into elongated territory, which has become the more fashionable of the two. Soft corners make this one of the most durable shapes for daily wear — there is no sharp point to catch or chip.
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.
