About the design
A sculptural half-cylinder crafted in solid yellow gold, Lettre Douce is defined by delicate horizontal fluting inspired by the woven metallic threads found in historic French objets d’art.
Each groove is hand-worked into the surface, creating a subtle interplay of light and shadow that enhances the warmth and dimension of the gold.
Finished with a smooth, flat reverse for comfortable wear, Lettre Douce is a study in refined craftsmanship — an intimate object reimagined in gold.
