Princess Cut Diamonds
The princess is a square brilliant: it keeps far more of the original rough than a round, which is why it has historically cost less per carat for comparable quality. If you want the largest certified stone your budget allows, this shape is usually the answer.
Its four corners are the weak point. They are the thinnest part of the diamond and the most likely place to chip, so a setting with protective corner prongs matters more here than the style of the head. Ask about it before you choose the mount.
Ratios of 1.00 to 1.05 read as square to the eye. Because the faceting is brilliant rather than step, a princess hides inclusions well: SI1 is generally safe, and colour tends to concentrate in the corners rather than across the table.
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.
