Diamonds Over $5,000
Above five thousand dollars you are no longer choosing a category, you are choosing a particular stone — and the reports start to matter in a different way. In this range we would rather you read the proportions than the summary grade.
Three numbers do most of the work on a round brilliant: table percentage, depth percentage, and crown angle. Two stones can both be graded Excellent and still perform differently, because Excellent is a band rather than a point. A table in the mid fifties with a depth around sixty-one and a crown angle near thirty-five degrees is the classic combination, and at this budget you can simply insist on it.
Fluorescence is worth understanding rather than avoiding. Strong blue fluorescence carries a real discount, and in the majority of stones it has no visible effect at all — occasionally it even helps a warmer stone face up whiter. In a small minority it causes a milky haze. The 360° video tells you which one you are looking at, which is why we put one on every stone.
Large stones also need the setting to be right. Every diamond here can be set in any mount in the range.
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.
