The Diamond, and Why It Was Chosen

Promesse Souveraine

The Promesse Souveraine is built around a 3-carat emerald-cut lab-grown diamond, colour F, clarity VS (3 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 three full carats, suspended from a 14K chain in white or yellow gold.

The diamond is F color, VS clarity — colorless, clean, laboratory-grown to the identical crystal the earth makes, and certified.

White gold reads it in marble; yellow gold, in gold leaf. Both are official languages.

Her Story

“Not an accessory. An autobiography, set in stone.”

Most promises are made in a moment. Sovereign ones are made in three carats, cut square, and worn where treaties are read aloud. Promesse Souveraine is exactly that document.

Three carats of emerald cut at the throat is state jewelry: long, stepped facets folding light into broad ceremonial flashes — the hall-of-mirrors effect, at embassy scale.

The cut conceals nothing, which is the entire diplomatic point. Every step is a window; every window is clean.

It hangs with the gravity of signed paper — composed at rest, incandescent in motion, never once informal.

Our Master Artisans in New York set the great rectangle in a reinforced frame, steps parallel to the degree, bail trued forward. Sovereign promises survive on precision.

Not a purchase. A declaration of arrival — ratified at the collarbone, effective immediately.

Not an accessory. An autobiography, set in stone — the sovereign edition, three carats, first printing.

Words get renegotiated. Stone does not.

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

The necklace photographed is finished, certified, and ready to ship from New York.

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.
