Heart Shaped Diamonds
The heart is the most demanding shape to cut well and the least forgiving to judge from a photograph. Everything rests on symmetry: the two lobes must match in size and roundness, and the cleft between them must sit dead centre and be sharply defined rather than shallow.
Size matters more here than in any other shape. Below about 0.50 ct the outline stops reading as a heart once it is set and prongs cover part of the edge — it simply looks like an irregular round. If a heart is the goal, start at half a carat and preferably above.
Aim for a ratio between 0.95 and 1.05: much wider and the stone looks squat, much narrower and the lobes lose their curve. Because the cleft and the point are both vulnerable, a five-prong setting that grips the point is the safest mount.
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.
