At D.Bachet, each creation reflects French fine jewellery craftsmanship, where material and line are carefully balanced. We work with certified recycled 18k gold and 950 platinum, alongside natural diamonds selected for their quality, origin and precise proportions. Every element is chosen with a strong focus on traceability and responsible sourcing.
Crafted in our French atelier, each piece takes shape through precise and considered handwork. Our jewellery is designed to endure over time, both in its structure and in the meaning it carries.
At D.Bachet, each creation is handcrafted within our French workshop. We prioritise one-of-a-kind artisanal production, far from mass-manufacturing standards, to ensure meticulous attention to every detail.
This approach allows us to craft jewellery with architectural lines and rigorous precision. By placing the artisan’s touch at the heart of the process and authenticating it with our Makers’ mark — our workshop’s signature lozenge-shaped seal — we ensure that our signed and numbered pieces possess an excellence and durability that define our Maison’s singularity.

The choice of our precious metals reflects a constant quest for precision and sustainability. At D.Bachet, we work exclusively with 18k gold (750/1000) and 950 platinum.
Of French origin to ensure environmental responsibility, our metals are struck with the State hallmark (the Eagle’s head for gold and the Dog’s head for platinum). This official seal guarantees the absolute purity and value of each of our creations.
18k gold: Composed of 75% pure gold, it is the reference alloy in fine jewellery. It offers a balance between brilliance and strength, ensuring the piece holds its form over time.
950 platinum: A rare, naturally white metal, distinguished by its density and stability. It does not tarnish and retains its properties over time.
Controlled origin
Our precious metals are sourced from trusted French partners, within certified supply chains that include recycled materials. Their transformation takes place in France, ensuring full continuity in the traceability of the material.
