The Diamond, and Why It Was Chosen

Harmonie de la Seine

The Harmonie de la Seine is built around a 2-carat emerald-cut lab-grown diamond, colour F, clarity VS (2 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 emerald cut is architecture in a stone — a broad open table and step facets that reward clarity with a hall-of-mirrors depth. It commands rather than sparkles.

An emerald-cut certified lab-grown diamond of two full carats, set in a riverbank prong mount of 14K white or yellow gold.

White gold is the Seine in winter light; yellow gold, in September's. Both banks are hers to walk.

Her Story

“Every great story has a jewel at its center. This is yours.”

The Seine does not rush. It has Paris on both banks and knows it. Harmonie de la Seine is two carats moving at that exact pace.

The emerald cut at two carats is the river at dusk: long, stepped facets carrying light downstream in broad, unhurried panels. No churn, no spray — current.

Its hall-of-mirrors depth rewards the patient eye. People will look twice, then a third time, then stop pretending they are not looking.

A cut this transparent keeps no secrets, which is why it is cut only from stones with none.

This one runs clear: F color, VS clarity — laboratory-grown to the identical crystal the earth makes, and certified.

Our Master Artisans in New York true every step parallel and level the table by loupe. Rivers meander; benches do not.

Portez ce que vous méritez — wear what you deserve. The river has carried worse advice and none better.

Every great story has a jewel at its center. Hers now has two carats and a current.

Cities are built where the water is this certain.

Want it grander or flanked? Our Atelier drafts your version free — a fully-rendered CAD in 24 hours, no credit card, no obligation.

The ring photographed is finished, certified, and ready to leave New York.

Easy monthly payments with Buy Now, Pay Later — the river now, the crossing paid in gentle spans.

Add Harmonie de la Seine to your cart — the current is already headed her way.

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.

The 2N Standard

Materials, Certification & Delivery

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.
