La Marquise
Heritage diamond jewellery defined by precision setting and timeless silhouettes — a benchmark of the maison.
A discreet atelier composing white-label collections, curated sourcing and bespoke creations for the world's most considered jewellery houses — from New York to Paris.

Atelier M is the partner of choice for jewellery brands seeking uncompromising craft without the burden of infrastructure. We work quietly — across diamond sourcing, master-set production and bespoke commissions — so our clients can place their name on pieces of irreproachable quality.
Three generations of atelier knowledge. One global supply network. An obsession with the millimetre.
A constellation of houses, each composed for a distinct sensibility — all bound by the same exacting standard.

Heritage diamond jewellery defined by precision setting and timeless silhouettes — a benchmark of the maison.

Effortless contemporary pieces, designed for the modern woman who wears luxury as a daily ritual.

Couture craftsmanship in pearls, gold and high jewellery — a quiet statement of considered elegance.
We craft entire collections under your name — from initial mood and material selection, through CAD and master-setting, to final hallmarking. Your brand. Our hands. Always behind the curtain.


For the singular commission — a one-of-one engagement, an heirloom reimagined, a private client's vision. We source the stone, draft the design and shepherd the piece from sketch to silk-lined box.
Partner with us to bring your jewellery visions to life. Our team is ready to discuss your requirements and craft exceptional pieces for your brand.
