Points of Note
- The Checkers necklace required 1,750 hours of work to complete.
- A femtosecond laser was used to engrave a houndstooth pattern into onyx, removing material without heating the stone.
- The central technical challenge was calibrating the precise depth of engraving: sufficient to create visible relief, never deep enough to compromise the integrity of the stone.
- Creative Director Claire Choisne dedicated the 2026 Carte Blanche to the human being, expressed through five jewellery sets.
- The collection explores both the similarities that connect people and the differences that distinguish them.
Carte Blanche 2026: A Collection Rooted in the Human Condition
BOUCHERON, the Paris-based high jewellery maison founded on the Place Vendôme, has long granted its Creative Director a space of total creative freedom under the title Carte Blanche. For 2026, Claire Choisne has turned that freedom towards the most fundamental subject imaginable: the human being. The result is five jewellery sets that examine what we share and what sets us apart, translated not through abstraction but through concrete material decisions and extraordinary technical ambition.
The collection’s premise is quietly philosophical. Rather than drawing from architecture, nature, or heritage archives, as so many high jewellery collections do, Choisne has chosen the individual human as her primary reference. Each of the five sets reflects a facet of that central idea, with the Checkers set functioning as one of the most technically demanding expressions of the whole. For collectors and connoisseurs across the GCC, where high jewellery is worn and appreciated with genuine expertise, this conceptual grounding gives the collection a depth that goes beyond decorative ambition.
The Checkers Necklace: Femtosecond Precision on Onyx
The Checkers necklace is the product of 1,750 hours of concentrated craft, a figure that places it among the most labour-intensive individual pieces BOUCHERON has produced under the Carte Blanche banner. The defining visual element is a houndstooth pattern worked directly into the surface of onyx, a material whose deep black offers both dramatic contrast and considerable technical resistance. To achieve the pattern, the Maison’s workshops employed a femtosecond laser, a technology whose micro impulses ablate material at such speed that no heat is transferred to the stone.
That absence of heat is critical. Conventional laser or mechanical engraving on hardstone risks thermal stress, micro-fractures, or surface discolouration. A femtosecond laser sidesteps all of these risks by operating in pulses measured in quadrillionths of a second, lifting material cleanly before any thermal energy can accumulate. The craftspeople working on the Checkers necklace had to establish the correct engraving depth through trial and iteration: shallow enough that the onyx retained its structural strength, yet deep enough that the houndstooth relief reads clearly against the polished surface. That calibration, repeated across the full surface area of the necklace, accounts for a significant portion of the 1,750-hour total.
Pattern and Material in Dialogue
The choice of a houndstooth pattern is itself meaningful within the collection’s human-centred framework. Houndstooth is a textile motif with deep roots in tailoring and fashion, a motif born from weaving and associated with structure, repetition, and the interlocking of distinct elements into a coherent whole. Translating it from woven cloth into carved onyx required not simply reproducing its geometry, but reconsidering how a pattern designed for flexibility and overlap would read as fixed relief in stone. The result sits at the junction between jewellery and applied art, which is precisely where the Carte Blanche series positions itself each year.
Five Sets, One Central Idea
Beyond the Checkers necklace, the 2026 Carte Blanche comprises four additional jewellery sets, each approaching the theme of the human being from a distinct angle. Choisne’s framework of similarities and differences gives the collection structural coherence without imposing visual uniformity: the sets can be read individually as resolved pieces of high jewellery, or collectively as a meditation on human identity. This dual legibility is characteristic of the Carte Blanche approach, which has consistently produced collections that reward sustained attention rather than immediate visual impact alone.
For clients and collectors in the Gulf region, where jewellery commissions often reflect personal narrative and where the relationship between the client and the maison is close, a collection organised around the individual carries particular resonance. Fellow high jewellery houses such as VAN CLEEF & ARPELS and CHAUMET have also engaged with thematic storytelling at this level, but the specific technical ambition of the Checkers necklace gives BOUCHERON’s 2026 offering a distinct identity within the competitive Place Vendôme landscape. The full Carte Blanche campaign is presented in the official BOUCHERON film, which documents the laser-engraving process alongside the broader collection context.
Why It Matters
For GCC collectors who invest in high jewellery as much for its technical and conceptual content as for its visual impact, the 2026 Carte Blanche demonstrates how a maison can deploy genuinely novel manufacturing technology, such as femtosecond laser engraving on hardstone, in service of a clear creative vision rather than as a technical exercise in isolation. The 1,750-hour production figure for a single necklace is a concrete measure of that commitment.

Frequently Asked Questions
How long did it take to make the BOUCHERON Checkers necklace?
The Checkers necklace from BOUCHERON's Carte Blanche High Jewelry 2026 required 1,750 hours of work, with much of that time dedicated to engraving the houndstooth pattern into onyx using a femtosecond laser.
What technique did BOUCHERON use to engrave the houndstooth pattern on the Checkers necklace?
BOUCHERON's workshops used a femtosecond laser, whose micro impulses remove material from the onyx without generating heat, allowing craftspeople to achieve precise surface relief without weakening the stone.
What is the theme of Claire Choisne's 2026 Carte Blanche collection?
Claire Choisne dedicated her 2026 Carte Blanche to the human being, exploring through five jewellery sets the similarities that bring people together and the differences that make each person unique.
