The Duo Luxe Silver Ring w. Emerald & Champagne Diamond

Gamme Blanche pieces are crafted in silver and gold — Marine has moved away from vermeil entirely, choosing to work only in materials that hold their beauty over time and can be worn in every situation without compromise. Production is small-scale and handcrafted, with responsibly sourced stones and metals, and close, transparent relationships with the artisans she works with. New designs arrive not according to a fixed calendar but in response to travel, encounters, and seasons of inspiration.

The design language is specific: asymmetry, soft curves, octagonal shapes, and a recurring fascination with the hidden. Many pieces contain secret mechanisms or unexpected details — symbols, as Marine sees them, of the interior life we rarely show. Her personal standout pieces are the POUDRE ring, an asymmetrical octagonal design set with two stones that conceals a secret opening, and the pendant LE PARFUM, inspired by her mother's bottle of Chanel N°5. Both capture what Gamme Blanche is at its core: jewelry that holds a story the wearer knows is there, whether or not anyone else does.
