Serti sur Vide — French for 'setting on emptiness' — is the Repossi setting technique in which gemstones appear to float against the wearer's skin without visible prongs, bezels, or supporting metal, achieved through internal structural elements concealed beneath or behind the stone. The technique has become one of the three signature design pillars of the contemporary Repossi house under creative director Gaia Repossi, alongside the Berbère and Antifer collections, and produces pieces that read as suspended diamond rather than as set-stone jewellery.

How the technique works

The visible appearance of suspension is achieved through a small internal frame — typically a slender wire or rail — that holds the stone from beneath or behind, with the supporting metal hidden by the stone itself or by careful placement against the body of the piece. The technique is distinct from tension setting, in which the stone is held by spring pressure from opposing sides of the metal frame, and from flush setting, in which the stone sits within the body of the metal. Serti sur Vide leaves the stone visually free on multiple sides, with the supporting structure read as an architectural element rather than as a setting.

For pavé and micropavé applications of the technique, the same principle is extended across multiple stones, with each held by individual internal supports that disappear into the overall composition. The result is a band or surface of diamond that appears to float against the skin without visible mounting metal.

Application across the collection

Serti sur Vide pieces include rings, ear cuffs, and pendants, with the technique applied across both single-stone and pavé configurations. The signature ring forms include the long, slender pavé bands that wrap the finger with diamond-only visible surface, and the single-stone rings in which a centre stone appears to sit on the finger without intervening metal. The ear cuffs apply the same principle along the helix and lobe, with pavé diamonds appearing to outline the edge of the ear.

The technique demands tight tolerances in both the cutting of the stones and the construction of the internal supports, and the production work is concentrated in the Repossi atelier in Paris and a small number of approved partner workshops. Serti sur Vide pieces are typically priced toward the upper end of the Repossi range, reflecting both the technical complexity and the visual impact of the technique.

Trade and design context

The conceptual lineage of Serti sur Vide runs through the broader twentieth-century history of low-profile and concealed-setting techniques, from the illusion settings of mid-century commercial jewellery to the high-end concealed-setting work of houses including Cartier and Van Cleef & Arpels. The contemporary version under Repossi is distinguished by the architectural design context — the supporting structures are themselves part of the visual composition rather than disappearing entirely — and by the integration with the Antifer geometric vocabulary in many pieces.

For collectors and dealers, Serti sur Vide pieces are recognisable on close inspection by the visible internal architecture and by the specific Repossi design language. Authentication of pieces presented in the secondary market follows the standard Repossi procedure of comparison against current production, hallmarks, and where available the firm's records.
