Round Diamonds
The round brilliant is the only shape with a universally agreed cut grade, and that is precisely why it stays the reference point. Its 57 or 58 facets are arranged to return light straight back to the eye, so a well-cut round forgives a lower colour grade that would show plainly in a step cut.
Because demand concentrates here, round stones carry a premium over a comparable fancy shape of the same weight. If budget is the constraint, dropping from a 1.00 ct to a 0.90 ct round changes the price far more than it changes the look on the hand.
What to prioritise: cut grade first, always. An Excellent cut in colour H will outshine a Good cut in colour E. Length-to-width ratio should sit between 1.00 and 1.03 — anything higher reads as visibly out of round.
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.
