Daumet proposes to the creators of the luxury an alliance of matters and innovative gold alloys.

The company, based in Paris, offers particularly the first shiny white gold in the world (CNRS patented process).

This breakthrough white gold named SpinD Gold presents several major benefits:

An exceptional white colour

With its yellowness index < 19, no more rhodium-plating is necessary.

Non allergenic

No problem with health or certification.

Cost advantage

Tungsten alloy is less expensive than current palladium gold alloys.

No rhodium-plating means reduced after-sales and logistics costs.

Environmental benefits

A reduced carbon footprint, less energy consumption and pollution emissions.

Decorative coatings
  • Gold coating production according to volume and shape
  • First shiny white gold in the world
  • Sale of the PVD coating process licence
  • Implementation of the process in partnership with our customer

Daumet could personalize your products for your specific needs and creative challenges.

On any matter
  • Whatever the matter you work, we adapt ourselves.
  • Wood (marquetry), silk, metals, polymers, glass, leather…
  • Your creativity is our only guide.

Massive alloys

The Daumet team is currently working on providing SpinD Gold in other manufacturing processes such as powder sintering or casting.
