Radiant Cut Diamonds
The radiant was designed to solve a specific problem: how to get the outline of an emerald cut with the fire of a round. Its cropped corners and brilliant-style faceting do exactly that, which makes it the most forgiving of the rectangular shapes.
Because it scatters light rather than mirroring it, a radiant hides inclusions and colour far better than an emerald cut of the same grade. You can drop to SI1 and to colour I or J with much less risk — which is why a radiant often buys visibly more diamond for the same budget.
Square radiants sit at 1.00 to 1.05; elongated ones run 1.25 to 1.45. The elongated version is currently the more sought after and looks longer on the finger.
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.
