The Marquise de Lumière is built around a 1.5-carat marquise-cut lab-grown diamond, colour F, clarity VS (1.5 ct total), set in 14K White Gold / 14K Yellow Gold and IGI-certified — independently graded, permanent, internationally recognised. It is a lab-grown diamond: atom-for-atom identical to a mined stone in fire, hardness and brilliance — the only reason a diamond of this grade reaches you at this price.
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 necklace 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 1.5ct . 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.
“Not an accessory. An autobiography, set in stone.”
The marquise was commissioned by Louis XV of France — the most elongating of all shapes, theatrical and unmistakable.
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 necklace rests at the hollow of the throat — the first thing a room notices and the last thing it forgets. This one was made for that moment: the one where she walks in and everything changes. The 2N Diamonds Signature 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. Wear it tonight on a Buy Now, Pay Later plan — 0% interest for 6 months via PayPal, or finance up to 24 months. You waited for the right piece. This is it.
This is the kind of luxury that does not shout, because it does not have to. Bring it home on six months at 0%, or stretch it across twenty-four, and let it be the one decision you made purely for you. You have earned every carat of it.
Every 2N diamond is finished by hand by our Master Artisans in New York — cutters and setters whose training spans decades, and whose rule is absolute: nothing leaves the bench unless it would survive a side-by-side comparison with anything in any showroom in the world.
These are the same diamonds we have supplied to wholesalers and jewelry houses for years — the exact grade, the exact craftsmanship. Now they reach you directly, at the price the trade pays, with no showroom, no middleman, and no markup standing between you and the stone.
That is the whole of the 2N standard: only the finest diamonds earn our name, set into pieces built to be owned for a lifetime and handed down — delivered to your door, insured, in a hand-finished velvet box that no one will open but you.
