The stone
Hydrothermal emeralds and lab-grown diamonds. Composition, hardness and refractive index identical to a mined stone — the difference lies in the place of birth, and in the price.


Fine jewellery — Geneva
Six pieces. Solid hallmarked gold, 9, 14 or 18 carat. Emeralds and diamonds created in a laboratory — same composition, same fire, an origin that can be named.
The house
We have reduced the collection to six pieces — four rings, a bangle, a necklace. Each exists in three carats of solid gold, all set with lab-created stones. It is a position, not a cost-saving measure: the full carat, complete traceability, and nothing to hide about origin.
Hydrothermal emeralds and lab-grown diamonds. Composition, hardness and refractive index identical to a mined stone — the difference lies in the place of birth, and in the price.
Solid hallmarked gold, never plated, never vermeil. Three carats for every piece: 9 for the sharpness of the drawing, 18 for the depth of the colour.
Every piece is mounted to order, in your carat and your size. Ten to fifteen working days, from the casting, in Geneva.

The campaign piece
The marquise is the cut that comes closest to the shape of an eye. An elongated emerald, ringed by a halo of diamonds, hung from a pavé-set bail.
We photographed it with no colour around it at all. That is how it is worn.

The emblem
An open bangle turned from solid stock — it is not hollow — engraved in a fan at the meeting point, an emerald cabochon at its centre.
It is the heaviest piece of the house, and the only one that carries the ocelle engraved by hand.

A stone born in a laboratory is not an imitation. It is the same stone — only its history is known.
