The Story

The marquise cut was named for a woman. Louis XV of France commissioned it to mirror the smile of the Marquise de Pompadour — the corners that reach outward, the centre that deepens — and it has carried that charge ever since. It is the most elongating of all diamond shapes, the one that makes a 1ct stone look like 1.5ct and a wrist look impossibly elegant. It is theatrical and it knows it. The woman who chooses a marquise has decided that her jewelry should be memorable, not merely present.

This ring was not manufactured. It was built — at the bench, by hand, by our Master Artisans in New York whose training spans decades and whose standard is that nothing leaves the workbench unless it would survive the comparison to anything at any showroom in the world. The centre stone is 4ct . The centre stone carries colour grade F — colourless, the last of the three grades that qualify as truly colourless under GIA and IGI standards. Clarity grade VS. It is a certified lab-grown diamond — atom for atom identical to a mined stone in fire, hardness and brilliance, grown in a laboratory rather than torn from the earth. That single fact is the only reason a diamond of this grade can be offered at this price: no mine, no cartel, no markup — only the stone. It is IGI-certified — graded by an independent laboratory whose results are consistent, internationally recognised, and permanent. The setting is white gold — cool, architectural, the metal that steps aside and lets the diamond speak first.

Some women wait to be given the things they want. You are not one of them. This is the piece you choose on your own terms, with your own name on it — the quiet, permanent kind of luxury that does not announce itself because it does not need to. You earned the right to want it. Now take it.

A ring is a promise worn permanently. It is the most visible piece of jewelry a woman will ever own, and the one she will be asked about for the rest of her life. This one was made to answer that question beautifully. The 2N Diamonds Private Collection exists because the best diamonds in the world should not require a showroom, a middleman, or a price that makes you pause. Every piece here is priced direct — up to 45% below what retail charges for the same stone, the same grade, the same craftsmanship.
