1.5 Carat Marquise Diamonds
At 1.50 ct a marquise reaches roughly 12 by 6 mm and covers most of the width of an average finger. Few shapes make this much impression for the money, which is the reason the marquise has returned after two decades out of fashion.
The bow-tie is the thing to inspect at this size. Marquise cuts show it more readily than ovals or pears because the outline tapers at both ends, and at 1.50 ct a heavy one darkens the whole centre of the stone. It is nearly invisible in a still photograph and unmistakable in the 360° view.
Because a marquise is shallow relative to its outline, it hides colour better than a deep shape would but shows inclusions near the points more readily. Look for a stone whose plot keeps inclusions toward the middle rather than the tips, where a prong cannot cover them.
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.
